i've been gathering parts for the last 2 yrs and coming close to completion. i need to know if this is going to be a good set up and if i need to make changes please let me know now so i can change it while i can. i was planning to use the stock intake manifold since it's got iab valves and just upgrading the throttle body with a spacer, if i can find one. please give all expert advice, thanks.

 

The set-up sounds good but build you listed sounds like the motor can handle in the range of 400whp. The Drag kit is going to limit you to making that much power.


What is your goal exactly in terms of power?

 

my goal is your guess exactly. i'm shootig for 400 whp but will be satisfied with 350. you think the drag kit will set me back alot?? i knew i should have went with the gt30r turbo. what do youthink i'll get ot of the drag kit????
