I'm being hopeful, but probably not realistic. I agree with your mindset. I'm going to cross my fingers and hope lol. If I can't get it where i want it, so be it. It'll still do wicked burnouts and break parts all day haha.

It was a T6 96mm 1.32, the big box stock one. With the quick spool AR was effectively reduced to .66 until around 7psi when the quick spool opened. Still a lot of mass for that little 4.8 to turn, though. Made a lot of power though, so you'll be in for some fun once it gets moving.
I'm a little on the fence with mine. I've got the 87mm turbine, T4 1.25 a/r. The T4 is really making me feel better about the turbo size. It will not be as fun as a s372 or a precision 66mm, but it should be ok.
I put twin s256's on a buddie's corvette a couple years ago. His ls2 spins up those 64mm turbines no problem, so I'm hoping mine will be alright.

Here are my goals:
1) Drive around truck with turbo on 7 psi and do burnouts. Hit the dyno. What will actually happen is that i turn it up to 15 psi and grenade my 4l60.
2) put on 4l80, turn up to 15psi. hit the dyno, go to track, see what it does and also do burnouts
3) build 5.3L on the side and put in truck. Crank up till i hit 1000 whp, go to track, run a 10.99 and also do burnouts.
