Heartbreak: Dream Engine Fails Instantly Leaving Us Speechless!

This is painful to watch. We helped Daiki build his dream 2.2 liter SR20 engine for his D1 Lights car only for the engine to blow up on the first round. While we aren't 100% sure why it failed we believe we found the issue after looking at the wiring harness.

You can see that Daiki is the most likeable dude in all your vids. Such a shame. Whilst he is an employee he is more like family. Head up everyone, dry the tears, get it fixed and keep on slaying!

[@jbake5022]

My dad used to always say “Every adversity, every failure, every heartache carries with it the seed of an equal or greater benefit.” Keep your heads up, the mountain top view isn't as good if the road to get there was easy. Rebuild, and comeback wiser and stronger.

[@dapperdanbuilds]

I'm glad Daiki has you, Sam, and glad you both have Oka-chan! It's good to have friends when things go sideways.

[@Aitchy_]

It’s also worth investigating the injectors (unsure if you put new ones in with the latest build.) Sometimes if the injector is clogged or for some reason the jets are not producing the correct spray pattern, you can have improper atomisation, lean spots and hence detonation… Injectors with these sort of problems can and will produce the exact symptoms you’re experiencing. Good luck with the rebuild! Daiki will be up and running again in no time.

[@foamdataservices]

That would have shown in the AFR read out on the logs.

[@Aitchy_]

@@foamdataservices No, not necessarily. Lean spots in the combustion chamber do not mean that the overall air fuel mixture is lean.

[@nikomoin7604]

Yeah but on all 4 Zylinders?

[@Aitchy_]

@@nikomoin7604could be the faulty wiring loom also causing the improper function of the injectors, not necessarily just a blockage. Also, just to clarify, I’m not saying the injectors were absolutely the problem… I’m just mentioning how they can also cause this issue… It’s better to explore all the possible causes so the issue can be fixed. 👍

[@thefunneyone]

Sometimes, if your injectors are too short or too long, droplets of fuel can form on the sport where fule is being injected to

[@SlenderHime]

I think the car is cursed, need shinto priest to purified it

[@hyota.x]

Yeah fr 🥲

[@jimrustle643]

Bless both cars and drivers and see if that works to get rid of the curse. If not, something's gotta go.......

[@XxflicksAFK]

lol the only thing cursed is your guys way of thinking I can reassure yous it’s deffs a mechanical fault lol but in saying that u guys maybe right an I guess it wouldn’t hurt to get blessed both of them and cars too

[@SHIZURAKU]

He's been blessed with a curse

[@bigdadgigachad3042]

You know Sam and May are going to be great parents by how they look after Daiki. I'm sure they are already great parents but as a parent with a child who is 17 and in college, you want to help make their goals and dreams come true. The fact they do this for Daiki, just speaks volumes to me. For not just being good employers, friends, but certainly will corelate to parneting as well. Yugo will be albe to follow his goals/dreams and have the full support and help of his folks. (and hopefully Daiki)

[@BariLopesh]

What are you talking about.. Like comparing apples to oranges...

[@duanebailey6253]

Congrats on the vibrant sponsorship. This is massive for you. Hope we get to see more of the dude that just moved from Australia as well.

[@BassManBobBassCovers]

YES!!

[@kamorx9624]

He has a youtube channel

[@iDreu]

poor daiki dude can't catch a break. At least he's got good people around him it's obvious yall are just as hurt as he is, it helps to have people who are empathetic when you're going through it

[@jasondal620]

Its sad to see Daiki struggle like that, you could really see the pain in hes eyes 😔 I am crossing my fingers and hoping for a fast return 🤞

[@jaynvius1]

You live and you learn. It's also good to see that despite everyting, Daiki still has a smile on his face and he's still very appreciative.

[@lukeemmo02]

It’s and SR we all knew it wouldn’t last. Just SR things.

[@MrLesm]

I think it says a lot about Daikis character, that despite all the bad luck he's had with the car he is still smiling.

[@playwtmk]

Daiki! You put your soul into that engine... When it's rebuilt you will have the soul of a phoenix! Much love man you got this!

[@aadams3316]

Awesome to see Vibrant on board. They've gone the extra mile every time I've dealt with them. Great people.

[@JDMRightHandDrive]

Well that is unfortunate new for Daiki. Sorry to see you dealing with an engine failure. I know how heart breaking, frustrating and expensive that is. My RB26 suffered from engine failure 2 years ago and I am still in the process of having it rebuilt. Best of luck to you Daiki, with Sammit's help and all the friends you guys have in the industry I am confident you guys will rebuild something amazing. Anata no yume o kizukimashou 🗾

[@Bobmarleytronjr]

Daiki seems so humble. Get this man right, he deserves it

[@zom2021]

Heartbreaking to hear, but Sam and Daiki will triumph in the end!!🔥🔥🔥🔥🔥🔥🔥

[@retrobear9367]

You're a good friend and mentor dude. The world needs more people like you

[@Fishbowl5.0]

I know it's a huge reach as a one man show or small team but every race program should strive to have a spare of everything on the shelf ready to go ahead of time. Okachan is the man!

[@KeViNMCMXXCIX]

Congrats on the sponsorship with Vibrant. Sad to hear about the engine failure. Time to rebuilt and renew! And come back even better!

[@Jon64scale]

Daiki a man of many words 😂 poor dude and his S15 dont worry Sammits got your back and will get the S15 back and stronger than ever 👌 and yes I know you got a new wiring system and thats great but Sammit as may called the rest of it Yakisoba 😂 I would definitely rip everything out every bit of wire and start completely fresh and rewire the whole car probably needs it and would help so much 👍

[@trevorsmith9251]

Daiki is in the best place to get this unfortunate incident rectified, it’s so financially draining 💯💰💵

[@jahmanglass5]

Total bummer man but you guys got this !! I just know it you an Daiki are gonna be standing on the podium this season !!! 🔥🔥🔥🔥🔥❤️❤️❤️

[@Albertius84]

Don't Give up yet, Daiki.......Me always support you.

[@foamdataservices]

I feel your pain. Positive vibes to Diaki, remember the car will be much more reliable and easier to monitor and maintain with the new wiring loom. My junkyard Miata is on bottom end number 2 and head number 3, it’s spent more days apart than on the road. Hopefully this times the charm and I can enjoy it. There’s some crap grounding faults in that loom probably too.

[@jeh5c]

Ahh Daikin good vibes onnya way buddy!

[@kingnorlen]

U know that in Sweden, where we had a few good high HP SR's we usually machine the head where the valve meets the head, to prevent detonations like this? Its not very common on SR's but i can assure u that machining off those "straight" edges and make them perfectly round makes a huge difference! Not recommended on SR's running 300-400hp tho, as it will lower ur compression a bit too much running stock-sized rods and pistons.

[@alanhall5648]

Oh Daiki you don’t deserve this such a cool guy , you guys will sort it out keep at it Daiki it will come good in the end. ❤

[@BassManBobBassCovers]

That really sucks to have such a bad detonation issue. Hard to foresee an issue like that without it exhibiting major symptoms. Then the open circuit on the knock sensor sealed that engines fate. At least the damage on that engine isn't worse. Not a complete loss.

[@hyper8545]

Looks like daiki having the same curse matt shulman had. 3 engines go boom until every inch of the car is perfection n then it finally worked xD

[@christopherharris6005]

Awesome video as always Sammit. Sammit you are one awesome dude for all you do for your friends. Daiki needs to have a shrine maiden come to the shop and perform a blessing on he’s car.

[@bubbalove5097]

Make sure you double check the rods didn't twist or bend from detonation if they are being reused

[@BassManBobBassCovers]

Yeah, with the detonation it's possible to tweak a rod, but given the bearings are perfect there wasn't too much downward force. Still good to check.

[@danino66]

Get him a new car!!. That one is cursed lol.

[@BassManBobBassCovers]

It was just the harness. It's close to being completely figured out.

[@KGC210]

I feel bad for "liking" this video. Hopefully Daiki will get his dream car soon!

[@MrOG3Drew]

Put the 2jz in Daiki's car.

[@livinglifeboosted1642]

You are spot-on with your diagnosis. I have actually seen this problem on a Ford Fiesta ST 180 that kept blowing pistons It was also a defective wiring loom

[@jeffreyhudon4428]

vibrant for the win 🎉 glad they are in the channel

[@LOKISX]

Sorry to see this happen Daiki-san. Keep your spirits up

[@coreycrosswhite8890]

I would bore it out, you just didn't want him to have a bigger motor then you, the bigger the displacement the more torque you will have and with drifting the more the better, just bore it out

[@driftyau]

already 2.2 sleeved, just gotta replace sleeves

[@nzuncovered1845]

Nah if you bore it out you increase the bore to stroke ratio which will reduce low end torque. Stroking engine makes more torque

[@Nolanmeows]

Damn that wiring harness is brutal, next setup is a winner for sure

[@BullyBreaker]

So dope the community is getting stronger and more supportive over time. Great to have genuine people and companies trying to support the drivers. Can only hope to be there in the spot one day too 🤞🏽

[@marcoalvarez6647]

Make sure the all the cables are crimped off,heat shrinked, electric tapped, and soldered properly and all your Grounds are good. Saw a issue where a loose wire would swing back and forth was make contact on turns and would burn out my ignition coil’s causing me to go thru about 5 sets of coils until I solved the problem

[@dgmcke3074]

So proud forndaikibthat he is now part of your team because a problem like that with his old team would probably have been a huge issue . Sammit you are an amazing friend to him and daiki deserve all the best he look like a genuine guy and hope the best for him and his car . I really think the harness will remediate to the problem but i think that his livery is curse . Change the livery on it if he is not sponsored by them i dont know that situations.

[@Midnight_Stone]

Those shoes got your feet in a choke hold. Using the strap is diabolical 😂 good to see D’s car getting a new harness 👍🏽🔥

[@ep82chris]

I think there is a few assumptions going on, surely if the knock sensor wiring was damaged u would see no knock sensor signal in the logs, was knock protective tuned and turned on as it’s time consuming to set up. Base timing set ok ? Still running stock sr trigger ? When it was tuned did they use audio knock detection? Hope it’s all sorted and this doesn’t happen again what a pain in the ass

[@Jon64scale]

Sammit amazing content 👌 but poor Daiki and his S15 and huge props to both of yous for always trying to help each other out no matter what even though so much is going on with yous like you Sammit with FD and Daiki with his FD thats the definition of true friends 👍 and thats very rare thes days you can tell not only are yous co workers but genuine friends and both so humble never lose that and huge congrats on the Vibrant partnership thats awesome 👌 keep the vids coming and keep up the great work 👍

[@krisr7512]

Lot of SR swaps I've had worked on most issues ive come by is from wiring issues and pre det. was common on test drive while found the wiring moving side to side mostly

[@brianrobinson9979]

Looks like it's time to try and get Daiki a sponsorship with Mazworx and get a Stage 2 built motor done up

[@idiedlastyear]

Sam mentions how many possible problems they ran into while building the car yet they still ran and drove the car, this is where someone has to actually put failure into consideration, dont blame no one but yourself, just accept that you failed at building a “good engine” stop deceiving these kids and subs you got

[@grapsorz]

build the new engine with a little bit lower compression as he have to run pump gas. the old head can have ben skimmed a bit more then you knew about. the bearings must have gotten beaten HARD so just replace them. ATLEAST pastiguage every rod bearing. even look over the piston pin and bearing. when it ping liek that the rods get a hell of a abuse.

[@uozx8074]

2J!!!

[@toddsupraman7609]

The link computer should have been able to tell you the knock sensor wasn’t working in my opinion if you don’t have the safety set up, you just hoping it gona last

[@geraldrogers9481]

People that problem is wiring issues not mechanical, I'm sure they've kicked themselves for not pulling an all nighter when the harness which was supposed to come earlier was delayed in being shipped... So just lay off the guys things happen and lesson are learned...Daiki will be back stronger than ever he's got family...👍

[@Thatdriftguy93]

You should give him yours sammit and you should build that block slowly. Since you know your sr22 is good to go 😊. That’s just my opinion. But I love your channel been with you since day one with the r33.4 the build with the yashio s15. Watching you grow and progress really inspires every one else to not give up with drifting and cars in general

[@Megus_Degus]

Way of the road. Keep on truckin.

[@ashborntempest4675]

Soo sad to see Daiki engine grenade itself but its still in good shape and its doesn't cost too much money to rebuild it also the wiring need to be change just from the wiring moving around and the coil randomly ignite its just made sense to do a full car wiring change just to have a peace of mind. Good luck with the rebuild and can't wait for the other build to be finish and other project to be made 😁😁😁😁

[@michaelbarry2534]

Hey Sam, I would be wondering if the fuel pump was starting to struggle or cut out (maybe because of the wiring) causing the engine to lean out. Running lean will increase cylinder temps and possibly the middle cylinders might get slightly better airflow which would mean they were getting even leaner then the rest. Just another possibility I guess.

[@victormeyer413]

Hey sam ive experienced this before in NZ the ka was a fresh import already built running 450wheel then it detonated to death. was replaced with a built fully forged 2.2 stroker motor with no expense spared an 2weeks later the same thing happened all 4 cylinders suffered detonation after going thru everything over n over turned out to be small amount of rust in the fuel tank an ever since then almost every s chassis that's been thru my hands has had rust in the tank ive had no issues ever since must be a easy 4 years later now an im running 600hp an i dont know if this ones running a fuel cell but even so could be welding slag just a thought bcoz the outcome of this is so similar to mine its not funny with how much they cost to build these days

[@craazyy22]

7:10 Doesn't the ECU have fault detection? You could on many brands add fault detection to sensors. Like no continuity is a big one. Or the opposite if the sensor reads over value aka shorted. If the ECU supports these functions, i recommend enabling it.

[@duanebailey6253]

Sadly it would be very hard to do with ignition. Its basically just sending a signal to fire. It's not looking for specific voltage as you want as powerful spark as you can get. It's possible to setup a knock sensor that may have helped. But the old obd1 engines dont really have it. Still dont know if it would show in this case.

[@tdkyt46]

A feature like that would have to be manually enabled and configured because false negatives do happen and it would get annoying

[@jasonpickens9839]

​@@duanebailey6253 I think the OP was referring to the knock sensor

[@htidking7961]

Improper ignition curve, If you are lucky, your detonation will be caused not by auto-ignition from a hot spot in the combustion chamber, but by an ignition curve that provides too much base ignition advance. If this is the case, a simple reduction in base timing will cause the knock to stop. In most cases, however, it will be the disconnection of vacuum advance that will have caused this condition in the first place. This scenario involves an enthusiastic newbie who disables vacuum advance, then advances the base timing to compensate. The whole reason for vacuum advance on a stock engine is to provide enough lead time under light throttle conditions when the atmosphere behind the throttle plate is thin; the engine requires that extra lead time for cylinder pressure to build prior to the power stroke. ie tuners fault

[@nevilleberghofer6791]

i feel sad for you guys but you will make it a lot better

[@weeaunsim4320]

Tuner should have noticed the knockings, either the tuner did a lousy job bacause u didn't pay him well or he just a shitty tuner, a good tuner would've noticed the knockings, anyway good luck to u & Daiki

[@htidking7961]

I agree and any open circuit on the knock sensor would throw an eml Something is really fishy about this supposed happenings

[@oldchev2850]

Most times these intermittent faults don't happen when you need them to. Maybe it only happened when he was drifting? How many times have you had something going wrong and you take it to someone to show the problem and it works perfectly? That's the worst thing about intermittent faults, they never happen when you're set up to test. Don't be so quick to bag out people.

[@matthewsammut5650]

obviously you have no clue about stuff just bagging people out. intermitten fault on a dyno will not always pop up especially if it is a wiring issue. the car sits in the one spot and doesnt move. a drift car gets sideways g force from side to side causing all sorts of wires and stuff to possibly move and earth out. there is literally nothing the tuner, sammit or daiki could have done any better

[@htidking7961]

@@matthewsammut5650 lol good effort to (bag) someone out as you said but sammit clearly stated it was clicking even before the engine was running. So be quiet
