408" with 6-8 lbs boost

You have to remember too turbo are the easiest on the whole rotating assembly cause boost comes in gradual, also less strain over a supercharger cause you use the engines own normal exhaust. For a cruiser and a little cheaper go with a air to air intercooler just have it up front. If you want a good company look at cxracing they have everything tubing, intercoolers of all shapes and sizes, I have personally ran one of their intercoolers on my srt4 and it held 25+ psi, good quality parts, they even have turbos, exhaust manifolds can just use cast iron just flip sides and run the tubing, better buy stainless steel tubing though. You want to run twins or a single turbo?
