Default Bw s475 or pt7675????
I'm in a dilemma! Please help me choose. I'm stuck between a s465 1.1ar 83mm (t4 or t6?) exhaust turbine or the cea pt7675. I'm shooting for 650-700 rwhp thru a 4L80E and fast spool. The bw is 1/3 of the price and from what I see just as good of turbo. I also thought a s480 but I don't want to have much lag. So this is why I need help!

Thanks.

$900 for the s480 and you would have over 1000hp potential. Mine on my 5.3 with a 4l80 spools plenty quick, although mine is the 92 mm turbine with the 1.10 ar t6 housing.

If size is an issue I believe the pt7675 is a smaller unit than the large frame BW stuff.

My radiator is stock location etc with the smaller precision unit.
