Thanks Larry for the content. Regarding the venting of hot air from the engine bay. Leave all the rubber trim at windscreen cowling. This is a high pressure area and best to leave trim intact to avoid high pressure air at base of windscreen push into the engine bay and slow the removal of hot air from the vented hood. This info was from a few years ago on the FRS/GT86 forum.
Larry, I loved the video content and the format. I've been on my own track car build for several years and have gone through similar issues. This insight was great and the build is amazing. I followed you for some time now and I'm really happy to see you get back on track.
For over the top weight savings, you might want to consider a carbon roof replacement (you need to remove the spot welded roof skin, but it does NOT compromise the integrity of the cars frame), you might also want to consider carbon door panels interior or exterior, the interior ones are about 700, and they retain the window and door handles, but make tons of space by removing the armrests and cubbies
The seat to base thing is definitely subjective to each driver - I've never needed to do that but I know plenty of other guys who prefer it, good seat choice btw. Love going back to videos like this for ideas
Removing the rubber stripping at the back of the hood would have the opposite to the desired effect on cooling. The top side of the hood at the windscreen is a high pressure zone whereas the underside of the hood is stagnant low pressure air meaning the extracted hot air from the vents would just get sucked back into bay. Sort out some ducting behind the bumper to force the air into the cooler/radiator and that should fix the coolinhg issues.
Love it! Could you do a video explaining the differences between building the gr86 for track, time attack, drift, drag (i know ours isnt built for that but curious), and whatever motorsports this little rocket can do.
love the global sensor camera you have mounted on your cage! cant wait to get my hands on global shutter on a mirrorless system will be ground breaking!
You’ll need to duct the front end to the radiator to ensure that all air that enters the grille is forced through the radiator and cooler. That should solve the cooling issues once and for all.
You'll also run into some fueling issues in the 86 if you intend to wheel-to-wheel race the car that you probably won't experience in a time trial session. Feel free to contact me for some build guidance.
Hi Larry!!! Wanted to know if you had any updates on the HKS Turbo KIt and if you have any numbers on performance yet and how it runs for you in comparison to the Supercharger kit?
Having tyres that wide might actually make you slower on track unless you had much more power, something to be aware of. Especially on sticky rubber like you run and I assume the wider rims. Try doing laps with 2 sets one 235 or 245 and the others you have the 265 and you will probably see the 245 is faster and feels better to drive. I've been around a few 86s that have gone super wide and then ended up back at 235/245 because it's better to drive and actually quicker on track.
GReddy also done a lot of nice kits over he years that were OEM friendly, particularly Honda/Acura. It was cool you could get a dealer installed turbo kit on a brand new Integra GSR and still retain the warranty.
I have a bone stock '23 BRZ and my fenders get EXTREMELY hot after a drive on a hot day (90+ degrees). The hood definitely gets hot but the fenders get so hot I can't believe the paint hasn't bubbled yet. Anyone know what's up with that? Oil level is fine, temp gauge is always perfectly normal etc.
I’m sorry, but I’m just not that impressed with those kind of power numbers. You’re adding a massive upgrade (N/A to boosted application) and you’re only getting 366hp to the crank (+130hp to the crank) and 294ft/lb or torque (+104lb/ft). The reason why I say I’m not impressed is because your engine is a 2.4L. For a 4-cylinder, that’s actually decently large. My 2017 2.0L-turbo 4-cylinder GTI came with 210hp to the crank and 258lb/ft of torque. With a Stage 2 tune, the power was bumped up to 366hp to the crank (+156hp to the crank) and 390ft/lb if torque (+133lb/ft). Those are better numbers than yours, with just a tune. Going N/A to boosted should net a much higher number than just tuning an already turbo’s vehicle. On top of that, my GTI has a smaller engine. So its numbers should be lower. But they aren’t. So no, I’m not that impressed with your numbers in the HKS turbo setup on your GR86. Cool car but still gives me “slow Toyota” vibes.
excited for the turbo kit! was waiting for someone to do this!

I think Japanese 98 Octane is that other scale, so it’s equivalent to 93 Octane in the US

heat treat or wrap your headers and a turbo blanket, gold reflect tape, bigger inter cooler.
Loving the Larry does racing content 👍👍👍👍
Larry when are we getting the install / update video on this!? Ive been waiting for months 😂
What an awesome build. In the words of the Donut Media guys...MO POWAA BABY!!!!!
My buddy has the HKS turbo kit on his FRS with a built bottom end. Makes a little over 400whp.
Couple of cars here in Australia make 450hp stock motor. But they had to build the transmission as that’s the weak point
By built bottom end / was it the hks pistons/rods etc?
Do these cars have reliable blocks?
Hi Larry!!! Wanted to know if you had any updates on the HKS Turbo KIt and if you have any numbers on performance yet and how it runs for you in comparison to the Supercharger kit?
Been waiting for this video
Sweet, love road courses, can't wait for upcoming contents! ❤
This turbo kit is definitely one of the best on the market, not to mention how it looks!
Is jdl better
The foam filters, not a fan of. I've extracted a few of those from plenums of various engines. They look cool when they are clean tho.

My gr86 is so jealous of your gr86. But you gotta bring back the white wheels😩😩😩
Need HKS to say this is CARB legal and I forcefully shove money to them 😂
hks are the king of Jdm my son liken the build Kidd she’s quality 🔥💯💪🏻
GReddy also done a lot of nice kits over he years that were OEM friendly, particularly Honda/Acura. It was cool you could get a dealer installed turbo kit on a brand new Integra GSR and still retain the warranty.
Awesome car, nice build!
That other yt guy just did 1:56 NA in a new GR. Shouldn't be an issue with your car. Good luck.
I own a GR86 whats up with that HKS supercharger kit??? 🤔
What cars are in your hot wheels display?
where can I find updates on the build?
I didn't know Larry was doing either of these motor sports 😂 nice car bro
Are you going to be at GTA ridge speed summit this year.
The hks supercharger was a time bomb in the first gen. Turbo is funnily more reliable in this case!
Where do you buy this. I want one for my 2023 BRZ
Will that intake just suck hot engine bay air?
Please come drive UMC!! NASA Nationals there in September!
That really is a very nice turbocharger kid! 😁
Did you remove the angle kit?
HKS, if you area reading this, I will go buy a GR86 if you sponsor me a turbo kit like this for testing!
Sik Larry, totally tubular!
Hmmm i dont see how adding a turbo will produce less heat but im in to see the results
I'm have a Daewoo Lanos project 🎉🎉🎉
I have a bone stock '23 BRZ and my fenders get EXTREMELY hot after a drive on a hot day (90+ degrees). The hood definitely gets hot but the fenders get so hot I can't believe the paint hasn't bubbled yet. Anyone know what's up with that? Oil level is fine, temp gauge is always perfectly normal etc.
Yo thinking about ebaying that supercharger? Lol
Run it at Buttonwillow!
Illuminating
so how much does all of these mods cost with the entire car?
Love it ❤
Get a seat mounted both to the floor AND cage.
Brother you should twin charge it haha
Still deciding between civic si or Gr86😂😂
Why not twin charge it ? Best of both worlds .
Twin turbo? On a 86??
Bbaddassery yo.👍🏼👍🏼🤜🏼🤛🏼🇯🇵⛩
Dang sure a good ol k20 from 20 years ago with 200k will make another 100hp on that turbo same boost lol
🎉🎉🎉
❤turbo❤
Turbo is only on the floor, not in the car
✌️
It would be cool if you shipped it to nordschleiffe and collabed with Misha!!!!!!
Gotta watch Larry Chen at 1.25x 🥱
Selling that hood? Lol
TURBO TOO SMALL AND I TUNE MY CARS WITH THE BEST GARRETT IF NOT TOP 3 FOR SURE GARRETT TURBOS
If you have a supercharged car and then you go turbocharged you need a straight jacket. You should not be allowed among normal people
ugh, piggy back is so ugly. Link pnp or open source tune is the way.
