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.
