Machine Shop INSPECTS My FORGED $300 M50 ENGINE. IS IT USABLE?!

I brought the block and pistons to the machine shop and they used a micrometer to measure the pistons and a bore gauge to measure the bore of the engine! We find out if the block is savable or not.

what would you guys do if you were in my position? help me decide!

[@anxtzyz]

k tune e30 (jk )

[@RyanRoadReaper]

Run the proper gasket. Don't cheap out using spacers. You can get away with that at low power and stress levels, but with the amount of power you're gonna make with a boosted S52, you're just adding another failure point to the equation and God knows BMWs don't need anymore reason to break 🤣

[@michaellee3310]

Build it back up and send it

[@AdilAaronAkhtar]

Machine/replace the pistons and run just a cutring gasket without a spacer Decompression plates on High compression engines is a bodge fix for low boost/power builds and not the correct way to do it

[@MarkyDGFX]

Use that motor that’s overboard which is s52 clone minus the throw on the crank you can use 86.5 or 87mm cut ring on ur block if the bore is greater than 86mm. I’d go 160-180 thickness for cut ring to get you some drop in compression if you like

[@undercutian9658]

“We’re diy guys we don’t know what that is that’s machine shop talk”😂😂 I love the content and the get it done yourself attitude

[@ellyboos177]

Take it to the machine shop to be resurfaced and use the proper mls head gasket 🙌

[@Ijustwantsometop]

BABE WAKE UP JOEL UPLOADED

[@FishFind3000]

Send it with the old owners setup and just put a tiny turbo and low boost so it spoils instantly. Or…. Super charge it.

[@gunerz3146]

These Videos are the best motivation to finish my e30 and just get my basic maintenance done on my other stuff… even when things aren’t going to plan you just gotta make it work and be smart with your $$

[@reyvoi5413]

thats what yalp be saying.for 3 years tea it down and build it up cost 6k no engine Lol

[@MarkyDGFX]

Keep the 10.8:1 comp factory is 10.5:1 use cut ring no spacer and use pump gas for 12-18psi set up and e85 for for the rest. Keep in mind high compression makes good power even FI those pistons are more durable than factory cast pistons to begin with regardless of the compression your using if your tuner is comfortable with it. I did 9:1 JE custom pistons on my s50 with eagle rods flex fuel motor i’d say it’s good for 800whp full e85 currently running 18psi-30psi max haven’t put it on dyno yet but should be competing at ///MPact next month

[@imnota]

That's what I would do, maybe even lower on pump but he's always driving on E anyways, with E85 and forged pistons high compression really isn't dangerous. I've seen some people do like 11.5 compression on E85, he only has 10.8 and even with just the cutring by itself it's gonna be like 10.5 because the cut ring is thicker than oem gasket.

[@henningberge4463]

Im a 18 year old boy from Norway🇳🇴 and the e30 has been my dream car for a very long time now. Im learning som much from your videos, and enjoy every video you post❤️

[@jeromejrolon-guerrero681]

I would get the proper head gasket, and put all new bearings and rings.

[@gsingh93]

Look up amp44 pistons, price is considerably less than most big brands. I'm using them in my m54b30 turbo, making 600hp for the past year no issues.

[@gediegengegonnt31]

Glad to hear that those pistons perform well, just bought some 8.5:1 for my m50b28 turbo.

[@Northern_]

Russian sanctions would like a word about that lol

[@harrisoncoulter1]

Dude. I’ve built a few motors and I think I would just send it. Be meticulous on inspecting the rings and cleaning everything but there is barely any wear from what I can see.

[@brettkrehling8738]

Pretty crazy how interchangeable all the parts are on these cars

[@squarrl]

flattest thing to get easily is a bit of glass then put wetsand paper on it.

[@rejjaN01]

Me and my friend, and pretty much everyone I know in Sweden who runs M50 turbos use the "Athena cooperring gasket" and it holds boost very well and seals good.(probably the same as the one you have, but rebranded?) My friend runs 782whp and 1053nm in his m50b28. As for rings, I dont see a problem using the same ones if they come from that engine, maybe double check the ring gap while you can. Depending on what type of bearing it is, I would change them if they are cheap kind becuase they dont cost that much(its a peace of mind type of investment).. Also run e85 to reduce risk of detonation, also more power.. My overall best tip is, do it right the first time. That's always gonna be cheapest in the long run. Cheers

[@terrancecollins2696]

Had to sell my JZ build because of personal reasons and was looking for another platform to build in the future … I’ve already found an M50 for $500 going to probably build that for my next build this channel is a huge help Also 10:1 is not really that high for today’s tuners lol there are cars running 12:1 with big ass turbos with a good tune obviously on ethanol/race gas

[@MFullaStyle]

I have a sudden boost of motivation to finish my big turbo jetta ..just giving me a whole bunch of ideas

[@walseee]

Keep up the amazing videos, Legit the highlight of my day

[@aaronkraemer9887]

I'd have the pistons cleaned up and run em, same with the rods, send the block to the machine shop for a hone, deck and hot tank. Have them mic the crank and give it a polish. Get the rotating assembly balanced, and put in a new set of main and rod bearings and piston rings. Run whatever head gasket thickness to keep it in the 9.5-10.5:1 CR with a factory or close quench. The high CR is fine you'll just make a ton more power on lower boost and the drivability off boost will be better and you'll spool faster. This will also help if you go e85 as the higher compression is more efficient and you'll be able to run less boost to make big numbers, which means less stress/improved reliability/fatigue in the long run

[@lurk9810]

This build has me hyped affffff

[@jevonharris4418]

Bro keep up with these videos its great how you go into detail with things !What machine shop did you use?

[@friguy4444]

From 0 to 1:57 YOU ARE PREACHING IT BRO!! The Snow Ball is REAL!! Don't do it! I know!! I'm finally using my second BMW which is a twin turbo but I'm so in Debt I can barely put gas in it!! No Joke!

[@ob9417]

loving the vids keep it up

[@twodogsyyc6729]

Killing it with the vids Bro. I would clean and polish/sand the gasket surfaces and put it back together with everything you have already..

[@vvssen]

keep making the videos bro these fire

[@rokuplayz464]

A high compression low boost motor is much more daily street car friendly than low compression high boost, keeping that compression helps with off boost power and keeps that decent fuel economy u get on longer drives

[@chr-rom]

I say you go mls. Fewer complications further down the road if your intentions are to be pushing P

[@ImJoel]

i’ve heard this a few times and is why i’m mainly contemplating it. i’m getting told if i’m running 30psi i want the headgasket to be the fail point and cut ring doesn’t allow that

[@Yurtle_Turtle]

Run mls , or factory oem style gasket blowing a head gasket due to detonation is much cheaper then damaging head or engine

[@Rnfjaydee]

Mls, just so if anything goes bye bye its the headgasket and nothing else

[@briankennedy6693]

Buy the right shit to put together a solid platform done right not cutting corners, this isn’t the area to pinch pennies, I wanna turbo my e36 328is so badly so loving this whole series

[@michaelmarques6706]

hand montage was kinda cool lol

[@mattumss3470]

its a good day when joel drops

[@fudawgable]

im suprised the engine shop didnt measure the deck height of the block if it needed to be skimmed. but yeah new bearings, rings and cutring headgasket - dont risk MLS on items that havent been decked...

[@beamerino]

kid cudi is litty, so is that travelers insurance shirt hahahaha

[@plugpenguin1660]

my friends unopened junkyard m54b30 makes 400-500whp reliably. they go for like $400 at the yard too

[@Blackf30.320]

Yo Joel , You should hit up some more drift events ! It’s good content !

[@baileymenzie1533]

Let’s goooo! Joel upload!

[@cesarxmbert]

ACL Bearings for the win. They cost me less than $300, both main and rod bearings.

[@bgpkilla124]

I’d stick with the bottom end that you just got even tho you’re worried about higher compression I’d say that’s what you want. Could use the same turbo or a smaller turbo with a little less boost and still make the same amount of power. Plus the turbo will spool up quick and you won’t get crazy boost lag.

[@vonknight5311]

If I learned anything from my bmw builds, it's don't cut corners. Sell what you had/have and get all new rings, bearings, and a proper headgasket after getting the machineshop to resurface the block. You'll have a bulletproof $15-20k worth block for less than $3k. You have peace of mind and if anything goes wrong you'll be able to pinpoint and be covered.

[@we-r-one_automotive.daniel3108]

Hell yea bro 💯 that's a score and a half.. told ya so lol

[@msnapp169]

See the mains looked perfect coming out and I bet more then anything he didn't get it line honed and he used arp

[@RuinedSpec]

Run the high compression setup. Low boost. The compression will make it peppy and spool happy. The goal is to get the car back on the road and have fun!

[@dylanhalouska47]

Do bearings and rings, everything else leave but don’t skimp on those two. Maybe new oil pump as well

[@fisom7120]

Nice video!

[@Natesgunstuff]

This is giving me motivation to finish my e36 😅

[@alecdenby1316]

We are DIYERS! That’s machine shop talk. Had me dying for some reason. 😂

[@gergodobi1796]

Cant you sand down the copper head gasket? So it fits better or something

[@drewdavis239]

s52 pistons have different wrist pin placement vs a 2.8 , if they are s52 pistons your m54 crank IS a s52 crank.. same part number.. the s52 crank may make the compression lower with thoes pistons . or its already a s52 crank

[@burntxtoastt]

How’s that powered subwoofer u got in the car. Is it a powered sub?? What model is it and would u buy it again?

[@firedustman]

hi there, i would like to know if eagle rods are good, i plan to turbocharged my m50, they says that it can handle 900hp... what are you thoughts ?

[@higherwrldsprodction2955]

are those rods aluminum? i would hope they're steel. theyll last much longer especially in a boosted application

[@jeremypartyka8510]

Re gap your rings for boost and send it!

[@jacoblami1731]

Just run lower pressures on the turbo...no need to mess with clearances to lower compression.

[@aaronle-garcia3891]

ngl im hella hype for you bro on the come ups lately been watching since the whole spinning out in front of cops to now. never stop grinding and sharing your journey. i hope as the engine goes together you remove the red paint and go black or something cause its killing me lol

[@boostedoctane8041]

Use cutring, no spacer on the previous owners setup.

[@msnapp169]

And m50 m52 and s50 s52 will make the same kind of power boosted properly and built properly

[@pullyoursocksup6302]

Homie looks straight outa TCAP 🤣 tell me I’m wrong!

[@bigdfig6083]

HAAA! A few vids back, the shop lighting/painting one I think, looked like homeboy got slapped the yamakah 8-□

[@brucelee7733]

5:42 what's up joel?

[@061garage]

Dremel that copper head spacer to 87mm If you're carefull thats shouldn't be impossible and its freeeee. Copper is very soft should be easy. use cut rings and head gasket that you have. Those bearing are probably used performance bearing or not just check them with some plastic gauge. Using the old pistons rings should be good since you know they didnt score the bore. Compare the ring stiffness between the 2 sets old ring. That forge motor ring are probably better/stiffer.

[@TheEvilPorkchop03]

How’d you find a trustworthy machine shop?

[@mugensohc2.271]

Joel run it add new upper headgasket kit and sell what you can make cash back .. or call up Rk-tunes “ .. and asks questions .

[@texaspowerman]

New bearings and rings, mls head gasket. Hone the block, set the rings up right,you’ll have a $20k motor for 2k. If it goes it should be the gasket, save you a lot of expensive parts. And you’ll know if it goes it wasn’t the mechanics fault rather than guessing if it would have spun a bearing if you had replaced them. Maybe a go fund me for some new bearings and rings. 😁

[@dewonesmikle4897]

It’s is if it helps u in the long run but if it doesn’t help don’t do it

[@deancastillo7]

Have you tried other machine shops for quotes? I think I paid just under $450 on my i6 too.

[@theswampernation6265]

I have a big snowball... smh

[@Merc-rt4vk]

🔥🔥🔥

[@EstorilE36M345]

Just run E85 and a good tune and send it

[@reyvoi5413]

engines been around.since.1990

[@MBWchannel]

Could you possibly have your copper spacer bored out by a machine shop to the size you need? They resize iron cylinders all the time it should be easier to remove material from copper.

[@Unknwn_4.0]

Put the other engine in the barn BMW for they both could be boosted

[@ElvisE46]

BROO Just send that shit reuse the bearings a rings and she'll be good. If she blows up just rebuild like you were going to build before

[@StraubelFilms]

Machine shop professional said slap it back together and run it… Slap it back together and run it. Worst case scenario you’re out $300 and time. 🤷🏼‍♂️

[@inaNis_]

Just outta curiosity, what’s preventing you from using the 3 liter crank in the M50 block? Also, mill the fuck outta those pistons man, even with the spacer you’ll still probably be hovering around ~10.0:1. Pistons need to get milled if you’re gonna reuse them, no ifs no buts. (For decent boost)

[@Sagekable]

The piston pin height is spec'd to the crank so he would have to get new pistons to run the s52/b30 crank. Also 10.8:1 is only .3 higher than stock, it will be just fine with a copper spacer especially with much stronger than stock pistons

[@inaNis_]

@@Sagekable the issue isn’t whether the pistons are cast or forged. With a higher compression, you will be more knock limited in your tuning. Yes the cast pistons will fail sooner than the forged ones, but it doesn’t mean that all of a sudden they’ll handle tons of detonation or knock. They might resist it a bit more, but at the end of the day you can still melt forged pistons

[@Sagekable]

​@@inaNis_ Yes I understand. This engine with a copper spacer and cutring (.140" of thickness) will end up around 9.2:1 which is a totally reasonable compression ratio for a built engine on pump gas. This thing is going to make like 550whp before it gets near the knock limit on pump 93 and it will make more than that turbo will flow on e85

[@slutkiller]

i would build a 12,000rpm na motor

[@msnapp169]

You don't have to line hone if you use arp 😑

[@hastheman7122]

Hello

[@M3Kiel]

Don’t re use anything. In my opinion the motor sounds good but you should use new internals!

[@JTAGxUsELeSs]

My man the way I see it, you know you're gonna beat the shit out of it. Have some peace of mind knowing when you mat it that you're not gonna send a piston through the bottom end. Post a clickbait video that should cover the funds LMAOOO

[@ohgarage9371]

om 606

[@msnapp169]

Line hone is only done for spun bearings or when a different crank or main caps are used

[@msnapp169]

That machine shop has no idea what there talking about if he told you to use sand paper to deck the block 😑 you will blow a head gasket again if you do that

[@minzahhh1]

Mate slap it all together and send it haha $300 gone if something goes wrong who gives a shit lol.... M54b30 swap if it dies could be a smart swap

[@ladin425]

The machine shop wanted nothing to do with that engine. He knew have a comeback wasn't worth it. I wouldn't trust that engine sealing with the 86mm bore and a blown head gasket. You will save yourself a lot of headaches if you go with a m50/m52 84mm block.

[@ItsJoshN]

Ya I was also thinking that they didn't want to touch it because what machine shop would turn away a hone, clean, and deck charge...even the new guys can do those jobs

[@jrt2924]

It's not always about comebacks. When i took my engine for machining the person taking it was thinking if they had time for me. Ended up taking it and took 4 weeks.

[@jbaccord]

I feel what your saying but also remember, the bigger the snow ball lowkey the more people get interested in vids which equals more money in your pocket 🫡
