S475 on a 5.3 with T56 Im still debating turbos and just thought Id get everyones opinion on this. Ive measured it out and I can definitely get the S475 to fit physically where I want it. My question is how well will this turbo perform on a stock bottom end 5.3 with T56? This will be mainly a street car and likely only roll race until I do something with the rear end. Goal is 700-750whp on E85. Cam I will be getting custom spec'd by Martin once I decide for sure on a turbo. BTW Im looking at the 83mm T4 turbine. If you dont think this is the right turbo, what would you suggest? Keep in mind I am somewhat budget minded and like the fact that I can pick this one up around $900.

Forced Inductions sells them for less than $900. Def a good turbo choice also eyeballing this turbo but in T4. Hope the T56 has some upgrades.

Watch this video of my s475 on 12 psi. T56, leaving at like 2500 rpm. Its a t6 96mm turbine, 1.32a/r with Martin species cam. Roll race its nasty but full boost before little before 4000 rpm. Its a stock ls1 besides the cam. But wouldn't think the 5.3 would spool much different especially with a smaller turbine. Probably spool faster.

Hmm, may be changing things a bit. I thought I had a buyer for my LS2 shortblock but they backed out. Starting to think I may just put pistons/rods in my LS2 and stick with the 6L 
As for the T56, its in a GTO so its an MN12, hoping itll hold up for awhile. Since I wont be launching it hard/dig race Im not too worried about it yet.
