I'm seriously contemplating a twin turbo setup on my '87 IROC. I know that I've wanted it to be boosted for quite a while just always thought S/C was the way to go.

I know I don't have everything covered, but hopefully this is a start.

Turbo headers
Turbos T3 or T4?
pipiing to and from the turbo and to the T/B
adjust timing (retard it, right?)
Wastegate / BOV (what does each do... can someone elaborate?)
Larger fuel pump and larger injectors (which ones)

This is going on a stock 305 TPI motor for now. Ultimately I will have a 400sbc with an HSR on top.

 

Heres your first start
