I've been told John Moss also has financial interest in W2W and it's sister companies. So you know it's got to be good.

Kurt and all the w2w guys are very knowledable. They were the first to get the 4l80 mated to the awd system without issues.
Last I looked their single kit was higher than most twin turbo kits with custom manifolds. )Their quality and reputation are first rate.

They also sale the rotrex superchargers that don't require custom fabrication.
