Hi everyone.

I started this project very long time ago and my first ET was 15.11. I had 2L engine and Evo 9 turbo back then. Now I'm running 2.4L stroker on E85 fuel and my best ET is 9.8 with Mamba GTX3584 turbo making 2.8 Bar of boost. I'm using standalone HKS F-con V pro Gold 3.24 ECU along with stock ECU ( to control 5-speed automatic transmission). In 2020 I'm planning to install aluminum conrods, PTE 6466 turbo, Tomei 290 camshaft with solid lifters, 250 HP direct port NOS system and try to make low 9'th on the quarter mile.

That's an impressive result from an Airtrek! Good job!

Thank you very much, Andre. It is especially nice to hear it from you. And I need to thank you guys for running HP academy so well - I have been able to pick up so many useful things and tips here. I appreciate it big time, thanks a lot.

Hi, Andre. Do you guys sell any stickers with your logo? I would love to put one on my car since I'm getting a lot of useful information from you and I would like to pay you back by putting your logo on the fastest Airtrek in the world)))

Wow, very unique build. Whats been done to the transmission to handle the power? Would love to see some pictures.

Hi. Well, stock transmission surprisingly appeared to be quite strong which was not expected at all. However we changed the planetary gears for the new type which has thicker pins (from Evo 9 vagon GTA), installed Borg Warner friction plates, enlarged oil channels in hydraulic valve body, upgraded the valves and raised pressure across the entire transmission system. And reduced gear shift timing as low as possible. That is pretty much it we have done.

I forgot to mention 4200 RPM Torque converter, rear Evo X RS LSD and front Evo 9 helical gear.

Forgot to post it here that best ET was improved to 9.5 with the same set up. After that i built another engine ( as was planned) with aluminium conrods and installed pte 6466. Due to covid thing no pulls were done with new set of hardware so it's planned for 2023.

That thing leaves the line very well. Good work!

Thank you. BTW, the other car was the champion of entire country in unlimited class with best ET 7.5... ))

Hi Shota,

Awesome build. I am also trying to build one for drag racing. I was wondering if you can help with me building the gearbox especially with getting right parts.

No problem. Anything I can help you with I'd be glad to share.
