As an engineer and engine builder in the past, that piston damage is negligible, it does nothing to the integrity of the pistons. Might create a hot spot but highly unlikely. If the ring lands are good and rings free to move it’s going to work just fine. Most likely just damaged in idle. Have opened Cosworth YB engines with much bigger valve contact marks and they were running fine and big boost.

Love the excitement you see in this man's eyes when he gets to pick apart a car and discover its history

Rem is finally getting the love she deserves. Heck I love it in general to see a whole engine tear down.

I would love to see more of these unedited engine builds. Theyre so relaxing but also informative to watch. Keep up the great work

When May giggled and said "so no way turned into this is wild" I literally had just said the exact same words.😅

This was so much fun! Thanks again for letting me hang with you Sam! Can’t wait to go back down and visit

You just can’t beat the “old school” Sammit where he gets his hands dirty stripping down a legend of an engine. Sams knowledge and skills are second to none and he is a pleasure to watch. This is the content we all love and I, like every other subscriber to Sams channel, will be waiting excitedly for the next episode in this exciting journey. Best wishes Sam and Mae 👍🏼

May: It’s an engine period Sammit: brief pause… Yes May 😂

It'd be cool if you did the reverse paint of the pink s15, blue with pink livery.

I think this car should become a better versed what it once was, I say keep the blue and put the original kit on it. But build the rest

@11:10 Looking at what appears to be mild-ish damage to the top of Forged pistons what probably happened was they told the customer it has damage that appears mild-ish but not cracked or broken. So your options are we can either spend thousands and do a complete rebuild or we can replace the head, smooth out the piston damage and do a compression and leakdown test. If that tests and looks ok you dodged a bullet. I have ran forged pistons with way more damage than this without issues to get by until I could afford a complete rebuild. As long as they didn't crack or crush the ring gap/seize the rings forged pistons can take a hell of a beating and survive.

Absolutely love the rebuild content. I'm glad that the sleeves are good on this engine and that the damaged pistons didn't scratch the bore. Can't wait to see it all getting put back together. Keep up the great work.

glad that the engine is in your hands now! Fix it, build it, shred it! 🔥🔥🔥

15:09 "its engine PERIOD" -May 😆😆😆

I really don't know how I would react if I saw something like this after giving my car to a workshop where they should know what they do. All the history about the abandoned s15 blows my mind.

love videos like this and i hope videos like this inspire people to stop trusting a random engine, dropping it in and sending it only for it to fuck up sooner than later. It's always worth going thru it so when it's running you know exactly what's going on with the engine

Ah, that was so exciting to see the teardown and double shooting, I am so glad you manages to find most if not all the answers toy needed for that engine

Nice to see you supporting the smaller Australian KZfaqrs with the Keep It Reet merch! #keepitReet

28:25 that feeling. Its too good.

Hands down my favorite series so far,keep slaying it.

Lets get SAMMIT to 1 Million subs by Christmas Day, Lets Go.

Sammit Detective, Sammit Detective, whatever the mystery it will soon be history! Finding all of those issues, full strip clean and rebuild with new HKS goodies

Dorm built 2.1 Tomei stroked, ran dry for first start.... pissed myself laughing then cried a little

I love how Sam can say something is “a bit how ya goin” but then says he’s gonna get his car “tooned” for big power 😂

Hell yeah sammit on sunday lets go !! been waiting for more of this dream car build

love engine disassembly and can't wait to see you build a new one for it!

i love this series of the blue abandoned s15

Definitely in need of some love... I know you'll make this poor neglected S15 a gem again 💎👌👍

Cant wait for all the new merch that will be coming REPPING SAMMIT HERE IN NEW ZEALAND ALL DAY LETS GET IT

Can't wait to see this completed 🙌

15:09 It's an engine period! 💕. That's WILD!!!!!

Very informative Sam, great video.

Awesome video as always. Keep up the great work.

Dude this series is awesome

Folks have been saying one was installed backwards for awhile. It’s crazy that it ran in that configuration to behind with. Hype to see it get rebuilt.

You get so excited about a few marks on the pistons. Nothing wrong with them. Take the sharp peaks off the indentations to stop any hot spots and all is good. Its a shame that some people will believe your lack if knowledge and throw away good pistons and waste money.

I literally started crying seeing the Pistons - who wants to know should Watch that

Hi sam love the vids and can't wait to see what option you choose for the Silvia

I had a piston in my stroker worse than that and it ran for seveal years made 480hp and 460tq at the wheels and had over 80k miles. It never lost compression, burnt oil, or gave me any tuning issues. If this was my engine I wouldn't be afraid to run those pistions again if it was a customer I would have second thoughts, as long as the cylinder walls or ring lands didn't take and damage I would run them.

Me and my brother love your vids s15’s are my brothers dream cars keep the good content going hope to meet u one day❤

At 10 minutes and I expected Okachan to walk in say a bunch of stuff in Japanese super seriously......and dip!

Amazing well shot and edited video. Too bad the engine was not properly built by any stretch of the imagination, but it is in good hands now! 🙌

Nice, love the videos, engine videos are always the favourite

Love the content and can’t wait for the rebuild of the engine to happen🎉🎉🎉 and I would just clean the block and change the internal and that it maybe do the head along the way

Chillax... Those pistons are still good... You overreact worse than my wife with stuffs 😂

This car went through a horrible journey but it finally landed in the right hands. I'm so excited about this build! 😁

Looking forward to this perfect end to the weekend 🎉

Take the rods to Tomei around the corner and get them to check the specs always good to double check they can do the crank at the same time then just some pistons from Tomei or HKS and ready to go.

I love your content bro keep it going

Love your videos :D Such great inspiration! Thanks for always making awesome content :)

Whoever built that motor didn’t know what they were doing or wasn’t paying attention. But a full rebuilt is def a answer

Love to see you take good care of Rem

Sam sometimes pistons can be repaired and reused. I couldn't see any cracks but on video you can't see much. Ask the old boy if they can be used again

im so hyped for this build !

Sick vid loved it can’t wait for more content

Learned something new about SRs. I've only rebuilt a 70s 350 so I have limited knowledge of these

love you guys reactions!!!

I love how Sam is now our Oka-chan, teaching us about SR's and engine builds 🙌

Hey mate, love to have content. I was thinking you should maybe do a giveaway with your broken pistons with a signature and what cylinder come out of, keep it up mate🇦🇺

Great video crazy what people do to the engine

15:08 Had me dying. sammit's little "yes may" LOL

I think you are now my most favourite Drifting KZfaq creator👍👍👍🔥🔥🔥

Love the content Sam!!!!!!

Awesome video!!

This was a super fascinating video. I don't know much about the mechanics of cars but I'd like to learn and I found this very educational! Would love to see more like this

Love to see this build go back to its former look. Or keep the blue and do your livery on it

Please go into detail with reassembly of the sr20det.

Its an "Engine Period" haha good stuff guys!

Absolute beast!!!!❤❤

🎉🎉🎉 I am glad you got to the engine in the car and by the way congratulations your new shop was amazing from the outside and I had outside and I hade opportunity to see it on this episode and see you guys more together working on what you guys love to do in your room people who love you and make it happen congrats

Love watching your videos

16:23 Damn ... Detective Conan is on it LMAO

It would be sick to go 2.2 or 2.4 seeing how the pistons could have miss shaped the cylinders. And since the pink car is a 2.1 would be interesting to have a different kind of build. Especially if u had a vvl head/correct piston combo, and the gen 2 garett you were talking about could be a ripper. Should have all the torque in the world, would love to see a 2.4 all dressed in yashio factory bits.

I can't wait to see this thing finished properly, I still think it should have a rocket bunny kit put back on it but I understand why you won't.

Love the car keep up Sammir your doing a great job

It kind of turned out the way most people thought it would. Because so many people worked on it and did repairs, not really sure who did what to it. The oil squirter would interfere immediately when it was cranked over, so they disregarded a bunch of steps. I think it was a good idea to rebuild, and it might turn out pretty good after 200,000 yen worth of parts and labor.

It is good that you pulled that engine apart

Just got an email that the Dream Shop Pack should be here by Thursday🙌🏻 hyped af!

things are gonna get interesting! canʻt wait till this is built and shredding🤙🏽

Beautiful car

thing i like the most is a merch hes rocking)

Yoooo more bistro content..the asmr vibes there sounded good..

Loving the content wish okachan had the time to tear it down with you his reaction would of been priceless 😂😂😂 I hope your bore's are ok 👍

Stance drift build thats responsive an works 💯🔥🔥🔥🔥

15:08 May has zero chill hahahaha

Konbonwa Sam. Music May, sugoi. What a mess and so lucky Sam. Such a dodgy piece of work. Great commentry and you were spot on , May. 👏 Jamata ✌️🇦🇺🇯🇵

Very good video looking for the rebuild m8

Love the keep it reet merch!

rebuild goin to be 🔥

Loving the blue s15 mad love and respect bro

It’s like I’m watching the discovery channel as Sammit discovers hidden mysteries with this abandoned build. 😬

Gawwwdd been waiting too see inside that engine for so long haha!

You get Mr hyped with this stuff love it

This something basically exactly like throtl would post and they still get at least 200k more views. You deserve more ❤

Love that outro.

lmfao nothing wrong with those pistons, as long as they arnt holy your good!! i have seen worse last a long time, under boost pushing big power too lol

lmao mae, engine period - that got me i wasnt expecting it

It just blows my mind how bad things could've gone but didn't. Whoever worked on this engine was very careless. But thats enough ranting, I'm honestly very excited to see what comes next and maybe even see some more misteries solved along the way? Cheers

The rods and Pistons could have been weight balanced, So the Piston is in the right spot but it was matched with a piston from a different cylinder in order to make a balanced rotating assembly. I'm saying this for a numbered con. rod point of view.

That's why I try and do whatever ever work I can from home I got screwed over by a shop when I first got out of highschool
