questions about tubo sizing??

[GstRacer]

ok i have a 16g and pretty soon it will be maxed out and my questions are can i put on a 50 trim or something like the same with stock internals and run 18-19 psi on it??? without having probs. that will give me more power but will i run into probs with that setup?? i have a rewired 255 fuel pump AFPR ss fuel lines 550cc injectors and a SAFC-2 what do you think??

You'll run out of fuel before you run out of motor.

ok well so....... that mean i can buy a bigger turbo with my setup and boost to 19 psi with no probs or are you sayin that at 19 psi i will be running out of fuel??

Yeah I've heard people say they max out 550s at 18psi on a 50-trim. You need 660s or 720s and then you'll be fine the 2g motor can handle about 450-500 hp before stuff starts breaking. For increased safety you may want to get some ARP head bolts, you can put them in without pulling the head.
