I have my W/G ran off a port in my I/C piping in front of my TB, and my BOV off the PCV port in the top of the intake manifold.

I read even non flex fuel pumps can support a pretty good amount of horsepower, don't quote me on that because that's the part I'm most confused about as well. What are you goals for horsepower?

I have a 4.8, I'm from the Kansas City area, and I'm putting a turbo on mine soon too. We may just have to race.

Lol ill race haha, ya I heard they don't do to bad, some I'm running stock pump and bigger injectors at about 7psi and have justune tune it. When I figure out my fuel pump situation then ill run more boost, my goals are atleast 650rwhp, but untill then ill be happy with 500rwhp on stock pump

on the turbo camaro im working on, the w/g control is off the i/c pipe, and the bov line is after the the tb. there is a port on the manifold you can use for the bov source.

if the camaro pops, im taking the turbo kit and putting it on the truck
