Default Re: 2008 JDM STI - EFR7670, 430whp for now....

Got my Car back on Thursday.

They modified the highflow standard injectors to use in the car until the new ECU Comes.

Dyno sheets to come soon, but they made approx 430whp on the Factory ECU.

Wow, is all i can say, the car now flies! No noticeable lag difference.

Also the sound the car now makes! Ive fallen in love. Sounds like a rally car with the new Downpipe and EWG! how all cars should sound.

Also amazed on the difference the Sway bars made, best value for money upgrade anyone could do! Eliminates all body roll.

More pics to come, but heres a quick one to start with.

Default 2008 JDM STI - 401whp 329tq - Dyno sheet attached

Received Dyno Sheet today.

Results 401whp 329ft/lbs, lower than the 430whp originally mentioned to me. is this low torque?

Welcome comments on this please

New ECU will sort that out when it comes. Overlap in injector timing with the factory ECU is cause the car to be a bit smoky/sooty under power.

Default Re: 2008 JDM Sti - 401whp 329 ft/lbs - dyno sheet attached.

with headwork, EFR7670 turbo, 98 octane, I would expect 450whp 400whp on a dynapack

I think the ECU is holding you back

Could definitely be ECU, but remember it's a 2L motor! won't be as torquey as the 2.5L

They limited it to 400hp to be safe with the factory airflow meter, new ECU comes in a few weeks, then I should be seeing approx 400kw atw (536whp) I was getting sick of not having my car so this was just a setup that I could drive in the meantime!

My tuners car is also a 2.0l he got 600whp, only difference on his car to mine is slightly bigger cams, Motul ECU and a 3.5" Exhaust system. So I have potential! Just got to get hold of this New ECU when it comes out.

Sorted my insurance today, they seemed to want to change my premium because of the modifications, how unusual! I have peace of mind as everything in current state is covered.

Default Re: 2008 JDM Sti - Brake Upgrade Needed to avoid Death

Brake upgrade suggestions needed urgently, had a severe case of brake fade on the weekend, which lead to the handbrake being used, spining out and going backwards through a busy main road intersection....

Fortunately no damage to car apart from a minor wheel curb scrap, and wheels out of alignment and managed to miss all cars.

Brake Upgrade for now will be Endless Brake pads and Motul Brake fluid. See how this goes.

Getting a wheel alignment done today, as the little incident threw the wheels out of alignment.
