How to build a RELIABLE 1,400 Horsepower LS Engine! 

Just a reminder that this content is FREE on RU-vid , this is great thanks for taking the time to make these videos!

I think Mike Kojima and Richard Holdener have taught me more for free on youtube then $50,000 worth of college courses.

THIS IS HOW ALL ENGINE VIDEOS SHOLD BE MADE ! WELL DONE FORMAT, JUST AWESOME ! THE ONLY THING THAT'S MISSING IS THAT YOU NEVER MENTION PRICES !!!! GREAT VID !!!

Drifting was an interesting motorsport but now you give me a greater appreciation for drifting as an engineering proving ground for bulletproof engines. Thanks Mike!

This was an amazing video. It is not about whether it is affordable or not, it is the free knowledge he is giving away. I have learned more about LS motors in 2 videos than in my whole life lol. I also want to know who the 43 people were that gave this video a thumbs down. Weirdos. Mike I used to work at Ground Control and I remember shipping you suspension stuff long ago for your Sentra's. Small world. I now have a 67 Camaro and I will be calling. Thanks for the knowledge

This is one of the best engine videos I have ever seen. THis channel is amazing for breaking down highly scientific data into means the average person can easily understand. Bravo!

I could listen to you talk all day brother. Love the videos, keep em comin

Love your work Mike, you have a deep understanding of engineering principals and I learn every time I watch a video of yours.

I have near zero interest in drifting but this dude is brilliant and this is one of my new favourite channels! 👍

WHAT AN UNBELIEVABLY GOOD PRESENTATION. Wish I had found it earlier. Thank you very much for taking the time to explain and upload. Geese I enjoyed this one.

love the video Mike. Stay safe my friend and see you guy soon!

As an LS fanboy I have to say this incredible. I am going to be building a 373ci 5.3 to turbocharge in a Silverado and I am going to try and use some of these tricks on my build. I didn't know alot of this was possible for my NA 416ci LS3 and my LS2 is just a low stress build. But the 373 will be boosted and built for more power and more abuse in mind.

We use the Bill Mitchell 9.800 deck block and push it to 1400hp for drifting builds as well we can run the exact same engine to 2200hp in drag or land speed racing which just shows what abuse a drift engine goes through We also prefer a higher crown on diamond pistons

Some say Mike is still smiling underneath the mask

I see what your talking about with the reluctor wheel it looked a little fatigued. All super good info and really easy to relate to awesome job.

Great content..........Also I love how he's breaking everything down to the simplest format!!! How can you not love this GUY!!!!!!‼🙌 Thanks ❤❤❤✔

mike is the automotive /engineering vesrion of stephen hawking the man knows everything about every micro detail about racing and he seems like the kindest most humble person as well if anyone deserves a phd in auto racing engineering its him great video i dont think people realize how informative this video is

Those internals are really something else. I am understanding more why going with a popular, highly developed engine platform makes so much sense for a motorsports application, 1000's of hours of iterative development and fine tuning into every component.

1400 horsepower for a season of racing is more accurate description

So refreshing to hear someone talk about something when they REALLY know what they are talking about. Gets tiring hearing confidently incorrect people all day.

Now that is a Awesome LS build 💪🇦🇺

A personal thanks for the meticulous explanation of what you do an why. I’m sold

I love watching you go over these builds... Your smile is infectious.. It's kinda heartbreaking listening to you struggle to breathe in that damn muzzle.

Good example for oil getting frothy is froth on the top of a mug of 🍺. I love your videos and find myself needing to put a new LS in my sons 2013 Zl1 Camaro. It 🤮 two rods and is amazing how much shrapnel ended up in the super charger including parts of piston rings over an inch long. 🥵

This man is my engineering spirit animal. Badass information.

Man, I love this! Also the wheels on that c7 fit so perfectly, I couldn't quit looking at it. Also, I would love to hear your thoughts on a good street build 4g63!

I AM FROM THE OFFSHORE RACING WORLD AND PARTS WERE MY THING ! ALL ENGINES OF OURS HAD CROWER CRANKS AND CARILLO RODS ! THOSE ARE SIMPLY THE BEST ON THE MARKET !

Just wen I thought he couldn't be cooler .. he rocking some dvs's! Love this guy

This was an excellent presentation of a superior powerful LS build. I WOULD LOVE TO KNOW HIS SECRETS !

This guys videos are absolutely excellent.

OUTSTANDING BIULDER. THANK YOU FOR. SHARING YOUR. TEACHING,. I'LL BE. USING YOUR MOTOR IN THE FUTURE

That crank is sick.

You’re a legend in knowledge mike thanks so much

He's a great salesman ... knowledgeable and a great speaker ... every time I watch his vids i want to buy one !

Thx u thx u this will be my first real power ls engine build.....built stock engines this is a new ball park for me thx u don't stop teaching

During our conditions, very well said , Thank You Very Much....😎✌ an its about time we got these quality parts available to us thank you again....🙂✌

Damn straight mike, tell them dyno queens. I laugh when people say my stock short block made x amount of power but their cars aren’t ran hard.

Man this guy is brilliant

Great video that lays out a killer blueprint for a serious engine...

hey buddy, you don't need to wear the mask for a video don't worry nobody is gonna hate on you for breathing in your own shop! Also good Video Please do more

I always like watching this guy because it looks like he is trying to look at every camera the whole time lol.

OK… these,guys are fantastic! You have a new sub with me, THANK YOU for this content!

I know he is still smilin big under that mask!😁

The Bob Ross of Engines, bro

I really enjoy your Patience and a very simple way and understanding Thank you Sir ~!

I had a lifter fail in my built LS2, I need to get the replacement cam and new morel link bar lifters wpc treated for sure.

Bro rocking the DVS shoes! Fckkkk yea🤘🏽

I'd love to have this in my C6 Grand Sport. Running 15 psi Procharged, but want more and convert to twin turbo. Good luck to my 6L80E transmission. Poor thing. Normally people go with a built to hell 4 speed but I'd like to do something goofy, and use a 10 speed out of a Mustang GT. In my GT, shifts are super fast but it would need to be build. No idea if that combo would work, but it would be interesting.

TY for sharing ... curious about the sequence of treatments ... do you cryo before or after WPC ? Cheers

I love the videos thank you for sharing your knowledge and for helping me develop my knowledge amazing work 🙏🙏

That engine is probably more than my car and I want it XD 5 year finance a motor lmao

As usual a really informative video. Thank you for taking the time! Also setting a good example wearing the mask through the entire thing.

Thank you for all the advice

Great video, wow! “That I’m willing to talk about”, not sure how you could’ve left anything out of this video.

Thank for this beautiful video

Great videos, love watching and reading pretty much everything you guys put out. Just one question on the block, are the liners supposed to have that offset where it is notched at the bottom of the bore? (5:20)

This guy is humbly brilliant

Great knowledge and university engineering professor-like presentation. Way to go Mike. Doing the ingenious engineering savvy Japanese people proud. Ganbatte kudasai. It would be nice if some day you can do the presentation without the mask.

Awesome video Mike. Learned a ton. Also good on you for rocking the mask.

man great discription ,love problems you see and how you build it better thru trail and error

I saw a drift team that was running a 1000hp Toyota 3SGTE, and they had to run so much big dollar hardware in that engine plus had to do a full teardown and rebuild after every event. Whereas a turbo LS could probably live for an entire season, or maybe do a health examination in the middle if needbe. But some people want to be diehards for a particular brand, I don't blame them.

Sometimes, the best classroom is a junkyard. There's a couple of things I can see consistently that begs a question. Setting aside the correctable oiling issues, just exactly how much squirming is going on inside that crankcase? Iron crank. Aluminum block. They put a thrust bearing in the middle of the crank - how much longer does it get when it is at operating temperature and where is the biggest change? Does the block get longer?

Amazing content! Mike is the man!

As someone who has built my share of powerboat engines, I think you have some great points. However, one thing in your choices I cannot wrap my head around, is the cam chain drive. I would never run a big power mill like that with a chain. I've fixed broken motors that failed because the cam drive broke. So much is going on and so many harmonics are sent through that chain. A belt not only makes valve event timing even more precise, it absorbs a lot of harmonics. For the same reason I will never use a gear drive on anything but a circle track motor. Do yourself a favour, use a Jesel or equivalent belt drive. Makes adjustment and install easier too. Your thought of doing things similar to what we do in powerboating makes sense, as it means everything is overbuilt. But get rid of that chain, in that price bracket there's no reason not to.

His videos are the 1st time hearing about wpc treatment and he sure does sale it well lol.. I want to wpc everything now,, and only thing is not everyone drifts and that's all he refers to lol it's all good bcuz if u building a engine think drift 1st and it will last longer

I like this format.

Can you show us how to build the transmission to go behind a LS?

Thank you so much for this content!

Awesome video, thank you for doing this

brilliant presentation, learned a lot from his tips

Sounds nice but expensive. I would love to buy a performance engine from you either a 5.3 or 6.0. but I'm sure expensive.

I wish you guys had packages you could pick from and build from there ..unless I’m missing it ...

Thanks for the information... maybe next time we can talk about building an engine... On our build which is complete, I am looking at the dry sump and the shaft rockers in the future...maybe. I have an automatic due to being DAV and this 6l90 is breaking every chance it gets. The 456 input shaft snapped this time... And the cam advice for boosted i.e.. LCA is what every boosted application needs to hear... Too many times I hear "but I want chop, chop"... Me I just want it running great as this is just for me... BTW why does anyone give a ... why you wear a mask or not... the jo's who complain can GFT.

Oh my!!! Daily-driver 1969 shortbox C10

As long as my engine builder has half of the knowledge of this guy I should be good to rip 😉, true craftsmanship in opinion attention to detail is great 👍

Them nhra nitro cars are hard on engines too

I'm curious. On the cryo treating. Does it help with any residual untempered martinsite. On the piston skirt shape. Technically it's called Cam Drop-off. Ideally yo only want a narrow band on the skirt to be touching the cylinder wall at a right angle to the crankshaft. Pistons have been made that way from the auotmtive manufacturers for years. We had Giddings & Lewis cam lathes that were programmed to cut a very specific profile into the piston skirt. G & L actually had special program they used for demonstrating just how good their control of the cutting tool was. Tey could run a machineycle and the G&L log would be machined into the skirt. The cutting tool was actually controlled with an amplifier

Sitting here drooling over the exotic parts and my girl just asked why I never look at her like that🤣

Mike, great video! I really liked the last one about the LS3 as well. Hey, I just talked to one of the techs at Fluidampr on Thursday and asked them to build a damper for the long snout crank for the drysump LS7 & drysump LS3. Do you think there is a market for that product? I will buy one if they build it! From an engineering and physics standpoint, the Fluidampr is a superior product and the reason why the Corvette racing team chose them. Can you ask them to build a damper for the long-snout LS7 and LS3? Please! I don’t know if my single request will convince them but maybe you have an idea how to get them to build it.

That 1400bhp engine is adequate. The 650hp barely got out of its own way, when I go to the store to get groceries.

Mike is a walking talking school Dude is a genius

Should reshoot this video with any updates or corrections added, and no dumb mask worn. Love these vids.

Love the series, thanks for sharing.

44:05 does the tig weld on the reluctor wheels cause any balance issues?

Beautiful Crank.

Brutal conditions are in Arizona desert running @ 120°F outside temps in the shade!

As always, Mike is whispering dirty engineering into my sweet ears.

this was a great video that answered a lot of question. some of it won't apply to my engine build though high hp not drift abused. If I sent in a list of questions on parts to choose would you guys respond yes or no for my build? thank you for all your knowledge. I really appreciate it.

How to build reliable ls Step 1: replace ls Lmao

would love too see the strip down video after a season

Please do an entire video about cryo treatment and wpc please and thank you.

Great interesting content, thanks for sharing.

Question, on your EJ video you also use inconel exhaust valves but you said you don’t turn down the diameter of the valve stem because you need it to endure the heat of the exhaust gasses. Can you explain why you opt to turn the diameter of the inconel exhaust valve for this application?

What a TRICK motor!!! Dude! Take my money!!! 😃👍👍

What is your opinion about camshaft less engines with "freevalve" for these high boost? It will make engine ligter because there is no camsfat and it's drive chains. And as valves is electric controled you can control it's opening and closing more precisly.

The TIG weld on the reluctor wheel looks like it has a hair line crack in it, not sure if you noticed.

I'm curious what your thoughts are on the RHS block vs the LS next block. Does one offer advantages more than the other? Great videos by the way, keep em coming.

A few questions for you Mike. 1. You mentioned that the bottom of the block is wider than a stock block. Does the stock oil pan fit the aftermarket block? If so, is the side outer most part of the block (in the oil pan area) wider/ thicker that the stock block? If so how much wider. The concern in width is due to fitting a 4l80e FWD transmission next to that block. 2. The next question would be: Pricing ?

Good afternoon Mike, do you sell assembled long blocks there're capable of 1400 hp under boost that will work for drag racing?
