T4 S475 vs 7475 So things have changed again and Im still debating turbo options, just wanted to see what others would think. The original plan was to keep the 6.0 Ls2 and put in Pistons/rods, now, due to budget constraints, Ive decided to sell the LS2 shortblock and pickup a gen 4 L33 5.3 and keep it stock internals. The car will stay a 6 speed for the time being, so definitely keep that in mind.
Im looking at going with either the Precision 7475 or the S475 with T4/83 turbine. I can basically get either for the same price. I know the Precision will be much easier to package, but Im a bit worried about it lacking the top end of the S475.
Power goals are ~700whp on E85. Motor will have a custom spec'd cam for the chosen turbo, springs, LS9 HG, and ARP studs.
