SR20DET Head Gasket Replacement How-To - Project GripS14

[@unijabnx2000]

I had some spots on my pistons that looked the same... just rolled with it, finished the gasket installed and still running great 3+ years later.

[@patrickdeed5143]

It's not common to find someone happy about a blown head gasket but i just blew mine and im pretty happy that you uploaded this and it really isn't all that difficult. Appreciate the video and if oyu could upload a video soon of the installation of the head studs id be forever grateful. Thanksss

[@speedacademy]

+Patrick Deed Well I was bummed at first but this is what happens when racing so I just look at it as a chance to create more content for the channel. Like showing you how to install head studs. I'll have a video in about 2-3 weeks depending how long it takes for me to get a used SR.

[@danieltubbs5422]

I've been binging on all of your videos during this crappy winter, this is my favorite channel.

[@JuniPapas]

It was sad to see the SR blow, what really made me tear up was the music used that put it all together (previous episode), but I'm glad to know that this beautiful S14 has a very great owner, I'd trust no one else but Peter with this S14. Great job keep up the perfectionistic work that is Speed Academy! Much love from Texas.

[@luiscovarrubias8941]

I don't own a sr or a Nissan but I just like watching any kind of video speed academy uploads :)

[@speedacademy]

+Luis Covarrubias That's awesome! Thank Luis.

[@JamesKim13]

Guys, I just came across your channel and I have to say I'm loving it! I am also in Toronto so It's great to see some locals building, may I say, at the highest, cleanest and the most professional level. I vote for an SR short block which will be reliable with some supporting mods and give you the least amount of headache. A bit boring yes but It's an engine us mortals can access so we can relate a bit better. Keep up the good work guys! Cheers!

[@speedacademy]

+James Kim Well thanks James! Great to hear you're liking the content. The SR is definitely staying. It's just a matter of whether I overhaul the bottom end of buy a used one. Decisions, decisions.

[@kernoodles]

this would be a great chance to make a video (or a series) about how to install an SR and what plug goes where. can't wait to see grips14 get a new heart and run again

[@speedacademy]

+Kern Lee I'll be shooting a whole video series on pulling the old engine and swapping in the new one so you'll get to see a bit of the install process. If you want a guide check out our site for a full details writeup: speed.academy/nissan-240sx-sr20det-swap-guide-part-1/

[@Headovrh33lz]

good to hear you're sticking with the SR

[@speedacademy]

+Ned 82 It makes sense, I like how well balanced the car is with it.

[@blankpage1995]

1jz would be so awesome. i dont know why everyone suggests going 2jz. unless you plan to make more than 5-600hp whats the point of buying an engine that cost close to twice as much when the 1j can handle 500hp all day. i hope you go 1jz in the future in at least some sort of rwd car on speed academy. these videos you guys put out are of the utmost quality and you guys deserve so much more sponsor support and subscribers. cheers for bringing us all awesome content.

[@speedacademy]

+That-JDM-Fascination! Thanks for the kind words. I totally agree, if I were to swap it Id go 1JZ. No need to make more than 350whp for this chassis to have fun in.

[@Fyxxterzc]

It's good to hear you're sticking with the SR. Was going to comment that a 1J would add mass over the front strut towers and add a little understeer. And with you doing an ls swap into a 240 before I'd go that route if you want to keep it "grip". That is if it can keep most of the weight toward the center of the car which you would know from your previous experience. Much luck with the build!

[@speedacademy]

+Fyxxterzc I think the SR is ideal for grip driving. I just need to make it more reliable!

[@shadowsaiyan]

Keeping that SR alive! Way to go, Pete! For a second, i was thinking VET head, but that's crazy talk!

[@speedacademy]

+duane willis That is crazy talk haha. I need to stick with a simple solution here.

[@shadowsaiyan]

+Speed Academy The K.I.S.S. Method of car building FTW - Keep It Simple, Stupid!

[@speedacademy]

+duane willis I like that and am DEF sticking to with this fix.

[@northerns1560]

Good to hear that you want to stick with the SR, hopefully you have better luck with the next one.

[@speedacademy]

+NorthernS15 I hope so too. This time Ill be a bit smarter with it so I should be good to go.

[@tjbenton3589]

So, is there a reason that you couldn't replace the pistons (and I would assume hone the cylinders?) and have the cylinder head repaired? Or would the cost of doing that be more than just replacing the engine? Either way, sorry for your loss. :(

[@MatteoVittoni]

You should really consider the swap option. 1JZ are great engines: they have a lot of potential still remaining plenty reliable. It is definitely going to cost you a bit more but it would really make the difference. Anyway, I must congratulate you for the channel. Greetings from Italy!

[@speedacademy]

+Matteo Vittoni I have a 2JZ ready to drop into my BMW wagon as my next project so I think I will stick with the SR for now in the S14. Appreciate you watching all the way from Italy! Thanks. :)

[@zacharyparis9830]

are you running the stock turbo? why the external wastegate?

[@mtk4158]

forge and go upto 450 bhp, hybrid turbo etc, love the show especially project s14 as ive a zenki s14 here in ireland and use these videos for advice. keep it up!

[@speedacademy]

+Micheal Kirwan Thanks, I'd love to build the engine proper but time and funds tell me to stick with a stock SR and just get it running again.

[@that.white.80]

5:55 Kens rx7 looks good all painted!! whens an update coming for his car?

[@speedacademy]

+Benjamin Ellsworth He's working on it slowly so we'll have a video up in the coming weeks.

[@juanc5149]

I ran a pitted piston for 2 years at 456 rwhp. Basically I had the pits polished out. And slapped the head back in!

[@Steve-qr2lm]

What caused the blown head gasket to start with?

[@DIGPLatinodriftking1]

I dont understand why you would get a new sr. Send it out for combustion chamber work, mill the head flat again, then get new stock pistons if youre on a budget. But I suppose if you're pressed for time then a new engine would be the better route.

[@michaelkarr7558]

+Xander Cage , yeah, this looks reparable. Need to find a good machine shop and head guy and it should be good.

[@sydneycbr6466]

+Xander Cage A whole new SR block can probably be found for less than the cost of that machining work.

[@iBLOODBATHproduction]

+SydneyCBR6 I agree. Also once you start having machine work done you will most likely just want to keep going. You will get more for your money because of bench fees most shops charge.

[@DIGPLatinodriftking1]

SydneyCBR6 Yeah but thats for the block. This guy needs a long block. So once he does purchase one he might break even as opposed to fixing this current SR

[@speedacademy]

+Xander Cage The cost of fixing this engine is way too expensive ($1500+) versus buying a used stock one ($700) and for my application I dont need a built engine rather a stock one with a good head gasket and studs should do the trick.

[@HellRaZarSR20det]

i remove the turbo housing every time . it makes it so much better to get the turbo out and off though i have an s13 so im not sure on clearance differences from the s14 . good vid brother thanks !!!!

[@masetcp]

how do you like the 1jz? I've had a ls1 in my s14 and I have been thinking 2jz. good luck thanks for your proper s14!

[@mcdadcoleman]

I was in a similar situation. I bought a used SR that was supposed to be fine but when I pulled the head to start to refresh the motor, I found bad damage to the cylinder wall between 1 and 2. The top 1/4" of the wall was actually broken off. Really bad. I had no come back with the seller. (no I couldn't do a compression test, the engine was on a stand) So I could either buy another used SR or I could resurrect the one I had. I sent the block off to be sleeved and have new pistons installed. That work is still being done. I also need to get the head into a shop to see if its ok. So, I don't think your SR is junk necessarily. You could buy another engine or do what I'm doing and make a bullet proof bottom end. It ended up being cheaper for me to go that route and I'll hopefully never think about the bottom end again.

[@speedacademy]

+Mark Coleman Damn, that's a shitty situation. I hope the engine that I buy is in proper running order but I'll be pulling the head so I'll find out very quickly if it is or isnt.

[@Monderakos]

this made me think of my sr20det, im going to tune it right now do i have to change the head gasket and the bolts? im running an evo 8 turbo about 1 bar pressure. for the build i would reccomend to build this engine if the block is good and the head, buy new set of pistons and rods ,build a proper exhaust manifold throw sr20de cams and you are good to go

[@speedacademy]

+Monder Phoenix It's never a bad idea but it depends what you are doing with the car (drift, track, street use). If you'll be road racing then I definitely recommend it. It can save you the headache that I'm about to go through.

[@Monderakos]

+Speed Academy i agree with you mate

[@harrish1978]

Hey mate what the warpage on Sr20det.

[@Martin-nc3nv]

same thing happen 2 me , i got all brand new parts for my built head and took it to the machine shop cost me around $700 for the machining but i took it to the best shop in my city that does amazing work, $2,000 into the head now im working on the built block .

[@speedacademy]

+Martin 651 If you want an SR that you can beat on then there's only one way to do it and that's build one to handle the abuse so you are doing it right!

[@GrantCulham]

Maybe I missed it, but other than the piston what's rendering the bottom end "junk"? Or are SR20DET cylinder heads by themselves not possible to find?

[@speedacademy]

+Grant Culham The bottom end isn't junk by any means but with the pistons being damaged it's pretty worthless, it's worth $100 or $200 bucks max since there are so many of them in this condition. I'll hold onto it and if I ever decide to build a built motor then I'll use this block.

[@deshiitimmons416]

Yupp I completely agree with you on that. Are we going to see an engine swap video.

[@speedacademy]

+Deshii Timmons Yup, Ill be pulling the old engine and install a running SR soon.

[@deshiitimmons416]

+Speed Academy yessssssss lol.

[@FentonDaniel]

Watching this video was so painful, I hate engine tear downs. Gotten to the point with wrenching on cars that it's not even fun anymore. I like driving not wrenching. Hope to see the car running in top shape in the spring. Any ambitions of swapping in some aftermarket pistons?

[@speedacademy]

+Daniel Fenton It was a bitch to teardown but on the bright side it made for a good video haha. Naa, the cost of putting pistons in and fixing the head is way more then me buying a used engine.

[@Frankjp555]

Did you weld the wastegate v-band adapter to the manifold yourself? if so what process was used and is this a long term modification?

[@speedacademy]

+Frank Pawloski I didn't. I had a local fab shop do it to ensure the weld penetration was proper. They drilled the hole in the manifold with a press then TIG'ed it up if that helps any.

[@Frankjp555]

+Speed Academy It does thank you! I know welding cast is a nightmare but it's nice seeing that some people prove it's possible.

[@speedacademy]

+Frank Pawloski With a powerful welder there shouldnt be any problems. A good fabrication shop can handle this job and it's very worth it. I have precise boost control with zero boost creep.

[@ndh8445]

external gate on cast manifold is tops! not many people realise the cast mani has better spool than tubular ones but also can flow a lot more than you would think (300kw)

[@speedacademy]

+thesamandnath I LOVE the external gate. The boost control is so precise and like you said the manifold has shown to make good power for me, 340WHP.

[@Alex_Lamus_99]

Forged internals for the replacement engine perhaps?

[@speedacademy]

+MrAlexLamus Not worth it since I just want to make a reliable 300-320whp. Stock should be fine with studs and a metal headgasket.

[@claudiodecina2670]

Awesome video very informative, I agree with sticking with the SR, it will keep the front more "Pointy" than the 6 cylinder swap, and it is a base that you are already familiar with.

[@speedacademy]

+Claudio Decina Agreed, the SR will stay because the car feels really good with it. I just need to improve some minor things and it should be super reliable.

[@claudiodecina2670]

+Speed Academy definitely, like you said ARP head studs will keep the head from lifting up under higher pressure, and also the multi-layer steel head gasket will keep things well sealed up. hoping to see the old girl running again soon haha :D.

[@speedacademy]

+Claudio Decina Lets hope it all comes together with no issues!

[@christianVSR]

Would a 1jz swap ruin your weight distribution? Sure it would make easy reliable power but what would happen to the balance of the car? Anyways thanks for the awesome videos

[@christianVSR]

What caused the detonation?

[@christianVSR]

What caused the detonation?

[@speedacademy]

+christianVSR It's a heavier engine so it will a bit but it all depends what you're building the car to do.

[@speedacademy]

+christianVSR lifting the headgasket.

[@KoreRacing]

Dang that sucks! Had a similar problem on a Jag XType I had for a while. Looking forward to seeing the new SR going in. Have you guys considered doing a series about going endurance racing? Not LeMons or Chump Car but like World Racing League, 25 Hours of Thunderhill or something similar?

[@speedacademy]

+KoreRacer We've actually been thinking about taking the FRS to 25hrs of Thunderhill but we just need to find a sponsor to make it possible. It'd be an awesome event to run.

[@mgdolbey212]

i would get a set of je pistons and rods for it and get the head sorted maybe flow it and cc it maybe a valve spring kit and she will be strong what do you think or keep it nissan and find a rb25det dont do the 1jz or 2jz route or stick a nissan V8 like they do with fordsburgs 350z

[@speedacademy]

+Matthew Dolbey It's going to cost too much to swap the pistons and rods and fix the head. Much quicker and easier for me to just grab a used working SR.

[@DriverModPlus]

would you consider getting a NEO VVL head with new forged pistons and ARP head studs for an SR20VE+T? or go with an NA high revving build?

[@speedacademy]

+BRIKKgoesHAM The cost of those parts and work is too much for the budget right now. I just need to get the car up and running with minimal expense.

[@DriverModPlus]

+Speed Academy in that case, would you reckon aftermarket rocker arm stoppers for the head? They should be somewhat cheap, and will prevent valvesprings and retainers from popping out under higher revs, and it limits the overall movement, and inertia in the valvetrain.

[@speedacademy]

+BRIKKgoesHAM I mentioned this in another comment but I have had bad luck with rocker arm stoppers so I dont use them. I also don't bounce the rev limiter so I should be good.

[@Happyliew98]

do something crazy !! swap a v8 ls1 !! price is pretty affordable and it definitely have power that you need or u can go nissan all the way with rb26 or just 2jz all the way :) awesome car project !! can't wait for next episode

[@speedacademy]

+TheNiceboy360 I've already done an LS3 swap into an S13 (kzbin.info/www/bejne/o4msop2XjdCbd5o) so V8 won't be something I'll do again, not in this platform.

[@simonnorup]

as long as the piston seal and the rods aren't bend your bottom end is okay. you should give the top of the piston a fine polish to knock off the high spot. the same goes for the combustion chamber as long ass your valves seal. you should check for warpage . i work as an engine builder and i have build a 6 cyl 2.5L bmw race engine with about 800hp that still runs now almost a year after it was done this way and that was necessary to weld the chamber to get it to seal

[@speedacademy]

+simon norup I agree, I think I could run the pistons as is if I wanted but the head has material missing around the valve so there's no way to fix it without welding, something I dont want to do.

[@garagemonkey526]

@@speedacademy late to the game but have a similar problem. So the block /bottom is good right? I am in same position but I can’t make videos off this and I’m broke!!

[@thicknick734]

when you blow a head gasket, should you worry about coolant getting into the block like by the crank?

[@thicknick734]

+Nikki Naydenov or into the combustion chambers rather

[@crazydogdude]

+Nikki Naydenov Honestly if you did an oil change it would just flush all the old contaminated oil out of the engine.

[@thicknick734]

crazydogdude fair enough

[@speedacademy]

+Nikki Naydenov The coolant that gets into the combustion chamber burns off but if you get it into the oil then an oil change is going to be necessary.

[@theorymotorsports]

Great video, thanks so much! I may have to do this soon on my SR and I'll definitely be using your video as a guide.

[@cruzader0]

Whats with the couple minutes of black video after the outro? (editing issue?)

[@speedacademy]

+cruzader0 Yup, brain fart on my part. That's what happens when I've been working for 12 hrs straight. I clipped it though so it's gone now. :)

[@cruzader0]

+Speed Academy Awesome :) Keep up the amazing videos!!!

[@TheTurbooneg]

I'm curious how you lifted the head? I thought sasha used to race sr motors and knows how hard they can be pushed? especially with meth/water installed......

[@speedacademy]

+TheTurbooneg Its not tuning that lifted the head, using a stock head gasket and head bolts (that I found out were re-used from a previous head swap) have to be what caused the head to lift. I was making too much power, Sasha told me 300-ish whp is usually the max on stock block but I of course got greedy.

[@TheTurbooneg]

+Speed Academy Thank you for the clarification, it makes much more sense now. That pesky power bug bites every time! lol

[@speedacademy]

+TheTurbooneg He said, 340whp is a lot for this block and I was like but I wont run it like that for long. Well it definitely didnt take long haha.

[@TheTurbooneg]

+Speed Academy haha....... Ive Def said the same before!

[@Bunchofhelmets]

Good to see the SR is going back in.

[@speedacademy]

+D.P.S Videos (DPSVideos) One more time and if it fails me then it's out for good lol

[@doctorlobsteroctopus]

Such a good an explanatory video! So sad to see the damaged motor though :(

[@jdmcommute]

Yep, I was going to start commenting about how this was going to be more than just a headgasket swap but I figure I would wait until the end. Lol. I wouldnt consider the block a paperweight though, with enough time and money it could be turned into a bored monster, the head could be ported polished and cc opened up along with bigger valves etc. but like I said. "Time and money" Its easier to go with another SR. I would also like to mention that usually the O2 sensors get screwed up when headgaskets blow. Something with the burned coolant that throws them off. So I would check on those or if your running a Bosch wideband maybe just replace it. Sweet setup though when finished. And more boost????? Lol!

[@speedacademy]

+jdmcommute Good call, Ill check the AEM wideband to ensure its working properly. As for more boost. Im going to be going with less, maybe 14-15psi to ensure I have a super reliable setup.

[@jdmDC2ftw]

Why do they not come with the superior head gasket from factory?

[@speedacademy]

+Dc2 Not for more power production. Stock boost OEM is fine but anything more and a headgasket is a good safety measure.

[@BenExell]

You seem so happy talking about your wrecked engine. I'd be flipping tables haha

[@speedacademy]

+BenXL Haha! When you do this for a living Ben you get used to blowing engines up. Plus I look on the bright side and think of the new videos Ill be now making. :)

[@JustinCB403]

can the old sr20 be rebuilt?

[@speedacademy]

+JuStin C. B. The block would need new pistons and honing at the very least. The head would require a bunch of work to reuse so yes it can be rebuilt but the cost will far exceed what I'll pay buying a used stock SR engine.

[@alexderus7480]

Have you told Sasha about this? What did he have to say about it?

[@speedacademy]

+Alex Derus Yup, when Sasha originally tuned it he told me that 340whp was alot of cylinder pressure for a completely stock block so it was going to be a bit risky especially for track use. I should've listened to him and turned the power down but I got greedy. After it happened, he said pretty much the same thing.

[@Elxmo]

Every SR I've taken the head off has had the same pitting in the pistons, one SR20DE, two SR20DET and an SR18DE from a Primera.

[@speedacademy]

+Elxmo Ugh thats never good! These engines dont take well to detonation!

[@SiGNALz]

Unfortunate ending but hopefully the s14 will be back soon! Cant wait to see the s2k with itb as well

[@speedacademy]

+SiGNAL We're working on both! The ITB job has turned out to be a bit more complex that we wanted but it's going to make for some cool videos.

[@NoGunLicense]

That sucks man! Hope every works out!

[@speedacademy]

+NoGunLicense It always does, just more time and money will be burned lol

[@MrDannyd9]

Machine the head, replace the pistons, and check the block decking. It is a good motor, and u can make improvements where you need it (lower compression to help with detonation), versus buying a stock SR20.

[@MrDannyd9]

+MrDannyd9 for about the same price too!

[@speedacademy]

+MrDannyd9 Not a chance. All that work will be easily $1500 dollars here. I'm buying an engine for $700 so that seems like a no brainer.

[@MrDannyd9]

+Speed Academy sounds like a steal! Did u ever figure out the detonation problem? Octane? Too much boost? Running lean? I know u had mentioned that the lack of coolant rendered a hot head, but what about the possibility that the overheating caused the old hose to burst initially? Then, exacerbating the situation. P.s. Is that Candian dollars?

[@speedacademy]

+MrDannyd9 The heat caused the detonation since combustion chamber temps must have skyrocketed after the headgasket failed. That led to everything else. Yes that's Canadian dollars.

[@internalcombustion8744]

damn dude i thought it would be a pain getting the water hoses off etc, but i guess they on the manifold and only a pain when taking manifold off . thats so good :D thanks for this video its amazing

[@brianrobinson9979]

I agree with everyone who is saying RB swap. Keep the heart of the car in the family (Nissan with Nissan, Toyota with Toyota, etc.) So RB26DET rename it GodzillaSGrip14 and maybe a Rocket Bunny Boss V2 Bodykit.... If you guys ever need any ideas for a build my mind never stops designing vehicles. I'm a truck driver who loves cars of all kinds. It helps me stay awake on those long night drives.

[@speedacademy]

+Brian Robinson Those are all great ideas Brian. I'd love to do an RB swap but right now its just not in the cards. I need to get the car running ASAP so I can start on my next project which means sticking with an SR on this one.

[@brianrobinson9979]

+Speed Academy what's the next project Pete? or do we have to wait and find out?

[@speedacademy]

+Brian Robinson If you watch the video you can see the car covered up in the background. It's my BMW E39 Station Wagon that I plan on swapping a 2JZ into. That's the next immediate project!

[@brianrobinson9979]

+Speed Academy that's gonna be outrageous! can't wait to see it come together

[@jonkat323]

Great video! An engine swap is going to make for an awesome video. Quick question, how come you don't run aftermarket slimline radiator fans?

[@speedacademy]

+Jon Kat Great question, I actually have a set of SPAL fans but have read many threads that say the stock fan and shroud are the best for flow and surpass any aftermarket fan option. The Nissan road racing forums is where I got all this info hence why I've stuck with them.

[@davidhong5556]

Why is the sr20 so illegal? Just got a s13 with a sr20 swap

[@speedacademy]

+David Hong It's not however in some states (california) its not legal because the engine was never used in the US.

[@UNKNOWNUNT1TLED]

do the 1jz swap you will not regert it

[@topherblais13gaming]

+isaac guibert no 2jz

[@topherblais13gaming]

yeah

[@ZWortek]

Build the SR, swap a 1j in or an rb26 :D. My vote is on building the SR, I think it would be sweet if you continued with it.

[@speedacademy]

+TheLastTank I dont have the time or money to spend building the SR. Instead Ill just buy another used one and seal it properly with head studs and a metal gasket.

[@ZWortek]

Speed Academy Understandable, you guys do have a lot of projects on your hands. Glad you're staying with the SR though.

[@JAracer21]

its a sr20det problem i had that happened to my gtir (pulsar) but i had the block crack and yes running 25psi with a hx35 will do that.

[@speedacademy]

+Andres Moxam Damn, thats bad. I was only running 16psi so thankfully it was just the gasket and piston and head that got ruined... Wait that's still alot of parts haha.

[@MistrMcGill]

in my opinion, leave the Silvia with its original turbo four design. just get the spark, timing etc. dead on and tuned to the t.

[@speedacademy]

+Mister McGill Thats the plan!

[@MistrMcGill]

Speed Academy and this plan will be the most balanced and fun to drive. I always wanted to build a car like Keiichi Tsuchiya's white Silvia S14. It's perfect!

[@mbsnyderc]

The damage isn't bad enough to need a new engine it's minor an won't effect the engine operation and it's repairable.

[@xtraCreamcheese]

Why buy a new SR? Is the idea of rebuilding it too far gone?

[@ryanbarbolt3691]

What's up with the FD?

[@speedacademy]

+Ryan Barbolt Video coming very soon!

[@Hayleboi]

Pete....do an LS Swap or a 2J...pleeeeeeese. I'll take vacation and fly up to CA and help

[@speedacademy]

+Hayleboi Haha, thanks for the generous offer but I've already done an LS swap into a 240 and Ill be doing a 2J into my BMW so I'm sticking with the SR for now.

[@ryancameron237]

Could maybe even push an rb or a 2JZ, would be nice! Lots of useable torque/power from those too! Only problem with that could be, it gets very expensive very fast... Good Luck lads!

[@speedacademy]

+Ryan Cameron Exactly, the costs add up so fast that I'm just going to stick with the SR since its the affordable and right choice at the moment.

[@ryancameron237]

Totally agree. And you can push enough power through an SR anyways!

[@trancextend]

And that's how my project blew up too. I have a ka that's been on development for a year now.

[@speedacademy]

+trancextend Cool! KA's can be really good engines.

[@Headovrh33lz]

sick another Speed Academy vid!

[@asquaredtheking]

@speedacademy get an SR20VE and swap it with a DE 8 weight crank and make crazy HP Numbers for displacement size.

[@speedacademy]

+asquaredtheking Sounds complicated and expensive haha. Maybe in the future but I need a simple fix at the moment.

[@asquaredtheking]

+Speed Academy good thought but just remember with a VE neo vvl engine people make 220+ NA power just imagine on boost. thanks for the reply love your channel!

[@PhoenixZong]

have it machined?

[@speedacademy]

+PhoenixBHO The block yes but the head would need to be repaired. $$$

[@CarsnStuff]

Forsure go with ARP head studs.. When i went single turbo i added a 3 layer steel head gasket and that thing handles all the boost and torture i want it to. Personally i actually torque my arp studs to 90 ft-lbs even though it was recommended by arp to do 80. Personally im glad i did it the way i did.

[@speedacademy]

+Review Guy Thanks for the advice, I also heard going to 90 isn't a bad idea.

[@CarsnStuff]

Yeah i mean i can only speak for my experience. I personally have had good success with what i've done. Im sure there are other people who have done things completely opposite with same results. but as long as it works for you thats what matters.

[@alloutofbubblegum8165]

it's a good idea to have a little bit of paranoia in regards to timing chains. but also that a bummer about your engine turning out to be junk now. i will be looking forward to seeing the next episode.

[@speedacademy]

+Norm Anderson Agreed, better safe than sorry right!

[@dhruvluhar5844]

Get the sr form the s15 spec r with the six speed

[@speedacademy]

+Dhruv Luhar They are really expensive and hard to find up here. 5K+!

[@dhruvluhar5844]

+Speed Academy Yeh i guess thats a big turn off :p what about an sr20ve-t?

[@speedacademy]

+Dhruv Luhar That's also a very expensive head and modifications to build a VE. Im sticking with the simple SR for now. :)

[@sanjujgeorge94]

It might be the water/meth system as they have been linked to detonation in some cylinders do to the mixture not reaching them.

[@speedacademy]

+Sanju George The mixture should be fine but Im going to double check the meth system when I get the car back up and running.

[@SailingGoonies]

Check a/f after rebuild if u weren't logging. Det could have caused gasket to blow. Would hate to see rebuilt head pop too.

[@speedacademy]

+DisplayName I was watching it while ripping on the track and it was in the low 11s so I wasnt running lean. Besides, I have AF protection set up in the EMS. If it runs lean it will pull timing and boost.

[@marcog8130]

You guys should do a 350z build

[@speedacademy]

+Marco G We've thought about it but since we have the 240 its a bit redundant at the moment.

[@bmw316iTurbo]

turbo is ok?

[@speedacademy]

+bmw316iTurbo I inspected the exhaust turbine and it looks to be in perfect shape so the turbo is going back on as is.

[@bmw316iTurbo]

i checked the following videos about this build, i seen you install the metal head gasket and arp studs, is the bottom end, head, stayed the same? or did you swaped for another? thanks for reply

[@speedacademy]

+bmw316iTurbo No the bottom end and head are a different engine, all stock still.

[@bmw316iTurbo]

more boost! thanks

[@FacuDvls]

yeah, i think the engine swap would be better. 1 or maybe 2jz twinturbo, that would be awesome!

[@90Alex]

I vote for the LS swap hahaha. Good luck with the build!

[@speedacademy]

+Alex S S Been there and done that so I'd like to do something else if I swap it.

[@90Alex]

+Speed Academy The VQ35DE can be another idea for a swap, or turn the SR20DET in a SR20VET. Anyway i will enjoy seeing the process :D

[@speedacademy]

+Alex S S I like the VQ but its too tall of an engine. Have to cut the hood to make it fit so I don't like that at all.

[@itzzToon]

all that work Pete. All that work, just to have it poo in your coffee. you cant have the block honed and the head machined and ported to fix this issue?

[@speedacademy]

+itsToon That's racing for ya! I could have the block honed, replace the pistons, etc. but the cost of all that will be double of what I will spend buying a used SR engine.

[@itzzToon]

+Speed Academy ....but what if it happens again? lol.

[@speedacademy]

+itsToon Then I start over and put an S2000 drivetrain in haha.

[@sparklingsams3155]

I just replace the water pump forgot to put the belt and I stood there watching coolant level then boom. Head gasket f up. 🙄

[@joseanbauza282]

2jz or Rb🙌🏼🙌🏼

[@CircuitAce]

Thank you for keeping the SR20

[@speedacademy]

+CircuitAce It makes sense. It's still a great engine. This time I'll do it the right and more reliable way.

[@KevinParra27]

sr20 Pete! maybe bore it out to a 2.2 liter! I'm shocked that you are still running a clutch fan and not an electric setup considering how long you have owned the car.

[@speedacademy]

+Kevin Parra If you go search around the forums the stock clutch fan is actually the best solution for cooling. It outperforms anything aftermarket. I have a set of SPAL fans sitting on the self but havent installed them because all the road racers recommend keeping the clutch fan.

[@imSchwaggy]

when you get the new one are you gonna bore it? (stroker) whatever its called lol.

[@speedacademy]

+im Schwaggy The cost isn't worth it. Way too much expense for the small bump in mid-range. It'd be cheaper to just get a 1J swap.

[@imSchwaggy]

+h0rr0r100 yeah i know. i wanted to know why they didn't do that instead of a swap. but he said it would be expensive.

[@goughgreer-barry1773]

might as well get some rods and pistons for it, upgrade fuel and turbo and really have some fun...

[@speedacademy]

+Gough Greer-barry Thats the right way to do it but right now I need an easy fix, used SR.

[@MC1796]

Coolest swap would be a Nissan VK56DE. They use this V8 platform in motorsports in the Australia Supercars series and Nissan put it in the GTR GT-1.

[@speedacademy]

+MC1796 Agreed but the cost and swap work is just too much for me right now.

[@MC1796]

Yeah, it is a pricey one. Have you ever thought about putting a VET head on the new engine and/or stroking it if the pistons are shot?

[@speedacademy]

+MC1796 VET head is a lot of work to mate it to the SR block and I just dont have the time and funds for that either. Same thing in terms of stroking the engine, the cost is not worth it for me.

[@MC1796]

+Speed Academy Yeah it is a lot of work just for VVT, cutting back the firewall is a pain as well. Well, I'm out of ideas haha. Ask Tomei if they'll give you a SR genesis motor for free, you know, for long term product testing...

[@speedacademy]

+MC1796 Haha, you know what's funny. I have good connections of Tomei and thought about it but then said it's still going to take too long to get an engine so I'm sticking with the junkyard SR lol.

[@ejbluth]

The joys of sr life.

[@speedacademy]

+Eric Jungbluth Truth. So much fun until this happens.

[@weskopr]

I prefer a full regrind on the head and deck the block before changing the gasket. Usually means you don't have to do it twice. :D

[@speedacademy]

+Veselin Georgiev Exactly, hence why it just makes sense for me to find a used SR that I can swap out the gasket and not have to deal with decking and fixing this engine.

[@brandoGTR48]

Why not go KA-T?

[@speedacademy]

+brandoGTR48 That would be going backwards for me. I pulled the KA to put the SR.

[@1dickycat]

Why not just rebuild the block you have? I mean, it didn't look like the block was all that bad, just the pistons and a lil on the head. Personally, I would just take the block to your machine shop and have them spec it out and magnaflux it to double check for cracks. Then id get the head ported and polished with new valvetrain. The P&P should take that roughness in the combustion chamber down and in turn, your head will flow much better. Just my $0.02..... Whatever you guys decide to do, please hurry! Cant wait for the next video! Makes my day when I come home from work and see a new SA vid!

[@speedacademy]

+1dickycat Cost. It will easily double the cost to rebuild the engine versus go buy a stock used one. Plus the time and effort it takes to build it will mean less time for other projects that I need to start working on!

[@1dickycat]

Ok, In that sense i can understand.

[@blu73]

well thats gutted.. but from a selfish point of view we now get more project grip s14 videos which is (for me) very good news

[@speedacademy]

+blu73 Haha, that's exactly what I was thinking. More work for me but at least there will be lots of S14 content on its way.

[@shyshydad]

New SR, ARP head studs, ACL Race Bearings, JE HG, JE PISTONS, Eagle Rods..... Wide up that boost boy!

[@speedacademy]

+Mathew Donnelly haha so much work for that. ARP studs and HG then go rip!

[@shyshydad]

+Speed Academy ;) hehe

[@Wcr3w]

you want to do the same with a sierra cosworth 4x4 :) You are cool with your tutorials thank you to you

[@speedacademy]

+serge benamou If I had time most certainly haha but I cant keep up with all my projects!

[@Wcr3w]

I hope so :) Continue your videos . They are interesting

[@ChaseDiaz_garage_works]

Overhaul, dyno, race, break and repeat. Good time to show a proper engine overhaul with his opportunity.

[@ChaseDiaz_garage_works]

With this opportunity **

[@speedacademy]

+Chase Diaz The cost of fixing this engine is way too expensive versus buying a used stock one and I haven't had much luck with built motors so I like to stick with stock.

[@ChaseDiaz_garage_works]

+Speed Academy word....but I think you guys should definitely look into the detonation issue a bit more. S14 on the dyno to see some data logging. Maybe iat is high..engine too lean.?? Who knows. You guys know what to do. I am rambling

[@speedacademy]

+Chase Diaz I've blown up a few motors in my time and trying to chase the cause often leads to a few unknowns which right now I really don't have time for. I want to just get a working engine back in the car and running so I can focus on a few other projects.

[@eoken1788]

sounds good! sad that the crazy chain of events happened.

[@speedacademy]

+Eoken That's racing for ya, it wont be the last time this happens either. When you're constantly stress testing parts engines tend to blow up.

[@jj1999cool]

I would love to see a rb26 but thats not very smart cuz of parts n stuf so get the1j

[@speedacademy]

+Julian0255x Plus, it would require so much more fab work.

[@fila1445]

i vote for engine overhaul. That darmage doesn't look that bad

[@speedacademy]

+fila1445 The cost and time aren't worth it for me. I'll buy another SR this week and hopefully get it installed soon there after. With a rebuild it would take much longer and that's time I dont have right now.

[@DiogoDC123]

I vote 1j swap

[@topherblais13gaming]

+Diogo DaCunha 2j

[@lilfluffynacho269]

I agree with the 1jz maybe a 1.5jz

[@BeeBeefy]

+Diogo DaCunha 1jz is good. Dont waste a 2jz on a grip car. 1JZ can get pretty decent amount of power

[@weskopr]

+Diogo DaCunha 1j's are pretty heavy, and for the power target i don't think it is viable to do a complete engine swap involving fabricating, electronics and gearbox and clutch magic. SR20's are good motors and a replacement should pop in in a day ;)

[@lilfluffynacho269]

+Veselin Georgiev true and I like a nicely built sr20
