you need to do a little more research regarding that question. what are your mods? there are different trims and housing sizes to that you are limited to, unless you're going all out drag and being unstreetable to handle. but for example, my setup is built bottom end, big IC, 8-injectors(680cc), stage 4 SPEC clutch, we have a 2.0L engine obviously and i have much more done, and i've bought a Precision SC34 T3/T4 turbo, which has a compressor housing side of 60mm, 57trim wheel,and a turbine side .63 housing,72trim wheel. this turbo can handle upto 550HP. i think for me and my goals is good enough. it's streetable and not too laggy and real efficient. the most i think i would go is a SC61 turbo or a turbonetics 60-1 ballbearing which is big enough and it handles 700HP. but that's if you're gonna be all out drag.

Also keep in mind a t3/t4 hybrid with 50 trim compressor can produce 48 psi, that is not the question though, the question is how much air can you get into the engine at what efficiency. keep in mind it is not wise to run a turbo below 65% efficiency and if you produce too much air to fast for the engine to take in you will get compressor surge......This is why you need to learn how compressor maps work. its not as simple as get the largest turbo you can and your set. A turbo that spools too fast for your motor is not good either.
