With Big turbo, fuel system , engine management, Cams, and all the supporting mods.
I like the styling of the STI. I just need to know that the engne will hold together at high HP.
My previous cars ar
711 RWHP MKIV Supra stock block
400 RWHP tt 300Z stock block
600 HP Eclipse GSX but with a built motor.


Right I need a four door. I know what the EVO engine can handle because I own a few DSM and Seem Dyno's on an EVo motors.
There is the Easy Street Kits i've seen that are in the insane versions of motors. 740 hp but i don't think thats stock internals.

I know 430hp with alot of mods is possible accordding to xcelleration.com 's webpage

I build my motors my self but time has been limited and I don't want to take a brand new motor and built it just so it wil hold up. I would like 500 hp to the wheel.

I might just have to wait for the EVO RM.


But I still like the styling of the STi better.
Then look no further:

504whp on race gas and 11.2 @ 128mph in the 1/4 mile. Stock block and internals. Clutch was obviously changed for the 11.2 run.
