- 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!
I'm glad Daiki has you, Sam, and glad you both have Oka-chan! It's good to have friends when things go sideways.
F y I vibrant Is a Canadian company not American
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.
That would have shown in the AFR read out on the logs.
@@foamdataservices No, not necessarily. Lean spots in the combustion chamber do not mean that the overall air fuel mixture is lean.
Yeah but on all 4 Zylinders?
@@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. 👍
Sometimes, if your injectors are too short or too long, droplets of fuel can form on the sport where fule is being injected to
I think the car is cursed, need shinto priest to purified it
Yeah fr 🥲
Bless both cars and drivers and see if that works to get rid of the curse. If not, something's gotta go.......
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
He's been blessed with a curse
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)
What are you talking about.. Like comparing apples to oranges...
It’s and SR we all knew it wouldn’t last. Just SR things.
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.
YES!!
He has a youtube channel
not worth the SR-issues over and over again... Sammit go 2-J. will be worh the time / money in the end.
im not Hating or trying to say i know better but remove the curse
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.
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
already 2.2 sleeved, just gotta replace sleeves
Nah if you bore it out you increase the bore to stroke ratio which will reduce low end torque. Stroking engine makes more torque
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 🗾
Put the 2jz in Daiki's car.
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 🤞
2J!!!
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
Sr20 life
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 👍
Are you saying "stoked" more often because of Rudnik?
Get him a new car!!. That one is cursed lol.
It was just the harness. It's close to being completely figured out.
Heartbreaking to hear, but Sam and Daiki will triumph in the end!!🔥🔥🔥🔥🔥🔥🔥
WHEN UR BUILD IS FROM TEMU 😂😂
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
Well guess who put the engine in it. ! That happens to all his cars. Time to go to some one with way more experience if everything Sam touches never lastes 🤷🏽♂️
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
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.
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
2 things . If the coils were randomly firing yes you would get knock bur Jesus you would have some huge intake back fires and some huge backfires when timing is retarded.
Also . If the tuner setup closed loop knock control you would realise the knock sensor isn’t working . If closed loop knock control wasn’t setup. The knock sensor was doing nothing anyway
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
I feel bad for "liking" this video. Hopefully Daiki will get his dream car soon!
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!
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.
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
I agree and any open circuit on the knock sensor would throw an eml
Something is really fishy about this supposed happenings
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.
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
@@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
@@oldchev2850 as I stated to the other comment, sammit clearly stated in the video it was clicking even before the engine was running and even showed it in the video so stop (bagging) people out as you clearly said yourself lol
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.
I'm a real Aussie cheapskate, but even I had a bad feeling about using the old harness with the new engine. At least you can make a video and get comments about it.
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.
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!
Make sure you double check the rods didn't twist or bend from detonation if they are being reused
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.
Odd every engine he touched has no lasted
Awesome to see Vibrant on board. They've gone the extra mile every time I've dealt with them. Great people.
Tune was abit to aggressive
Total bummer man but you guys got this !! I just know it you an Daiki are gonna be standing on the podium this season !!! 🔥🔥🔥🔥🔥❤️❤️❤️
You're a good friend and mentor dude. The world needs more people like you
A built engine is dependent on who built it😮
Have you ever thought that maybe Daiki isn’t meant for a SR? Problem solver: LS SWAP.
Blasphemy lol
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.
Ahh Daikin good vibes onnya way buddy!
you should a distribution deal with vibrant to bring such stuff in and make them available to japan. oh yes do show okachan some vibrant love 😊
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
The link didnt tell you the knock sensor wasnt working?
how big is the squiss ! have u made it lesser than original???
Well i guess it’s time to put a k series in it
A SR20 blowing up wow who would of thought😂 Get Daiki a good motor like a RB or JZ
If he wanted something other than the SR he would have gotten it already.
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.
Congrats on the sponsorship with Vibrant. Sad to hear about the engine failure.
Time to rebuilt and renew! And come back even better!
Daiki is in the best place to get this unfortunate incident rectified, it’s so financially draining 💯💰💵
vibrant for the win 🎉 glad they are in the channel
Don't Give up yet, Daiki.......Me always support you.
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. ❤
💯👍 Time for another rebuild
Dont trust the bearings. They will have unever wear from the detonation.
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...👍
Oh bugger. I’m coming over to Japan 🇯🇵 in 4 weeks. Would love to meet the crew if possible and shout you all dinner. Cheers
please make sure the rods are still straight, round and in spec, crank isn't cracked etc. that level of detonation can destroy all of it!
Bummer. Fu+k major failure. Daiki's big bro. Okachan is the S God.🙏 Daiki. ✌️💙🤘🇦🇺
Hopefully y’all learn from this and don’t rush a car into a comp that is known to be compromised
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.
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.
A feature like that would have to be manually enabled and configured because false negatives do happen and it would get annoying
@@duanebailey6253 I think the OP was referring to the knock sensor
If the to of the sleeves aren't too eatin up you could go oversize piston and deck the block down. My pistons are 90mm. Can go uptp 92mm
With that much detonation I wouldn’t risk running those rod bearings. They might look good but they can lose their shape so then u run risk of spinning a bearing. For that sake of $100-$150 bearings is it worth risking
I don't know if they have this product out in Japan, but my engine builder coated my pistons and inside of head with DiamonDyze. Could be something to look into for heat management.
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
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.
You dont change one thing and cost failure.... Thats call karma.... Sam, i thought, you had learn this think already on your cars
Feel sad for Daiki but light on end of tunnel is coming for him because of 3 of yous 😊
Swap in the single jingle rb20et from the Bogan you have seen its superior reliability😂
Should've just sent it to a professional the first time, doesn't matter if you did your own engine.
Machine shop, new piston & wiring harness. Slap it together and add lots of boost! No biggie, could have been so much worse!
😢 2j swap 🤞🙏
Sorry but wouldn’t the eml come on with an open circuit on the knock sensor. Also yes a premature or late ignition would cause a audible pre detonation. Sam your good at what you do but you should have picked this up before hand
The car is a bad egg, something somewhere is off by a billionth of an inch, and eventually it will trickle to a big problem. Get a new car
Well this is motor sport and motor sport SUCKS, 😂 so many engines later we still do it! Live to drive!
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
Looks like it's time to try and get Daiki a sponsorship with Mazworx and get a Stage 2 built motor done up
Do they use th QR25 in a rear wheel drive application in Japan on any vehicle? They have to be very cheap there wonder if anyone uses them or are they useless...?
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.
Daiki u need to get your car done without sammit... I bet ur builds will be fine I think sammit doing it on purpose
Sad that people thought Roberto was a clown from detonation causing a bearing to spin. I know it is a diffrent situation. But in both cases the pressure will cause wear and a bearing will spin.
Agreed with wireing my r33 engine had my piston all the way melted. Piston did not look like a piston anymore.😂
Damn that wiring harness is brutal, next setup is a winner for sure
Daiki seems so humble. Get this man right, he deserves it
From back when I worked on stuff....... God I hate SR's.
credit to daiki for downing the car evven with corporate presssure. dang... cant wait to see what daiki can do with a good running vehicle
worth while for the price and time, to actually change the big end bearings as they can oval out from detonation
As above i would think it would of been a fuel issue or wiring to injectors or some kind of starvation issue that would make it detonate
Crank sensor? Or wiring to it? Could be effecting the timing...
Dam is there a way you write this off in tax , that engine didn't get enough screen time !! . That's a lot of damage
I think the car is cursed just like my Nissan Hardbody:(
Idk it seems like yaw somewhat knew something was off but yet decided to still drive it?
Support poster signed by Daiki ?
Love he's running an sr.
Its because you didn't let it idle for 24 hours straight for break in
If the knock sensor was never connected, the map may have been out anyway...
Sr20 Crack additions tees 😂 idk how you would make it pg
