my current setup is a stock gsr top&bottom j1 tranny and a straight t3 turbo. when it was dynoed i was very disapointed. i only made 175 and i forgot how much torque. the little turbo stop making power after 7200ish rpms. so ive been told i need a bigger turbo. my question is <U>what turbo do i upgrade to</U>. keep in mind its a stock motor. but i want a strong power band. looking for in the neighborhood of 250hp. what experiences do yall have with yalls setup.
hope my questions were clear.
thanks

 

probably a t3/t4 57 trim would be perfect for you, full boost around 4.5 and will pull till reline. should see 250 at about 7 psi also. Or if you have cash, a gt28r/gt28rs would be the best bet, spools quick and can make that power.

 

i like the t3t4 57 trim .63 a/r should make 250 easily

 

anyone willing to trade a t3 for a t3/t4?

 

you have pm

gt series turbos...ooooo yea
