this is my first time posting and was wondering for some help on how to reach my power goal. i have a red top sr20. with an exhaust header, greddy front mount intercooler and piping, greddy fuel pressure regulator, Walboro 255 fuel pump, rebuilt bottom end all stock with metal headgasket, 3inch straight pipe, 300zx TT MAF, Apexi stand alone power fc for sr20 redtop.

I wanna reach around 340-400whp but i do alot of auto crossing so i want to see if it would be better with a t3/t4 or maybe a t28 or what other suggestions and what type of injectors and anything else that i might need.

i've been searching all types of 24o forums but i haven't really found the answer that i've been looking for. thanks to all that can help me out.

 

Garrett GT2871R would maybe be a good turbo, you wont see that kind of power with a t28. Your gonna need 550cc inj with a good tune as well. full 3in. turbo back exhaust, a good clutch, some good valve springs/retainers and some rocker arm stopers.

if this is an autox car why do you want that much power?

 

wanna have enough power just incase i start going to road racing. because the second you do a swap then you gotta go against the modified vets and those kind of cars.

Was thinkin on this turbo but what would be a good company for the valve springs, stops and retainers
