Default Looking to replace the TC78

Like the title says. I've searched and researched , but can't find a solid answer. Looking to upgrade, but wondering if the PT88 is too small for my setup? Buddy is selling his turbo https://ls1tech.com/forums/parts-cla...-bb-turbo.html. But wondering if both the compressor and exhaust wheels are too small. Listed below is my motor setup.

Forged 376 c.i. w/ comp cam 226, 232 115 LSA, A4, 3600 stall.

What are your goals? The pt88 has gone really fast and is a very proven turbo. Depending on weight your could go bottom 9s or 8s with a pt88

I would like to get to the low 10's and around 850-900hp if possible. Standing my radiator up over winter and upgrading my fuel system again.

if you have room, better options out there than the pt88

if you dont have much room it runs rather well and on a budget

I will have the room after re-mounting my radiator upright. What would you suggest? I know some have replaced the PT88 with the GT47-88 or S380, S400.

Why are you needing so much hp for low 10's?

If it where me i would get in this order, there is a price difference though

1. Gt5088
2. Toss up between gt4788 or borg 80 or 88 with the big 96mm turbine
3. FI's new 97mm turbine version of the gt88

My 2cents
