help picking a turbo ok i see tons of ls based tech so it makes it kinda hard to find the info im looking for. OK well im planning to build a 383 with about 8.5-9.0 to 1 with a good set of brodix or afrs and im going to build my kit cause i want to keep my street car comferts like ac an ps, i would like to stay with a t4 frame so i can fit it better but i want to make 700ish on pump gas and at least 100 more on the kill setting if not more and can you keep the ac condenser and go with a stand up radiator.

Compressor is the problem, not the condenser if you run meth.

So you think a tc76 will flow 100lb/min??
Which is what you need for 900whp.
What's the diff between a TC and a HPS?
How about running a 383 with each?

I've been looking at GT45's

PT88 is T4 flange. Different compressor housing, different exhaust housing, and different turbine wheel.
I've yet to track down the turbine specs. I need them to see where my current hope for custom single falls between an S turbine an the PT88. The shop immediately tried to sell me a new $2500 turbo vs the rebuilt one they have listed.
Not me....
I have a truck now and sold my car prior to building my sbc twin 58mm setup.
Keeping the ac... go 355 and get a 76HPS. See the first link I posted. Just not much room in there.
Or squeeze twins down low.
