Default turbo upgrade question

i have a PT76GTS Turbo. T4 .81 a/r. on the car now and im looking to up grade it to something bigger to make more power what would be a good turbo to go to?
i dont have a ton of room where the turbo is so is there something with a bigger wheel that would bolt right up without changing anything else and make quite a bit more power?
what is this turbo good to rwhp wise?
this is goign to be on a 383.
im new to turbo stuff and dont know much about it.
thanks ken

How much power are you making/how much are you shooting for? I know that going to an 88mm is a fairly popular choice, but I know nothing, and would wait for someone smarter to step in.

How much boost are you running, compression ratio etc .. I think the 76 should be able to get you there.

The Precision 78GTS would be alright, but the PT88 would be better for more power.

I think some people are getting more than 700 to the wheels on 76's on here. I think you should move up to a .96ar for a little more top end out of the 76 but for 650 I think its in there.
