Can a B18C be safely boosted with the high compression without rebuilding the block? If so at how many psi and where's a good site to purchase a turbo kit for it?

 

gsr spec is a little better for turbo than type r spec B18cs, so go with the b18c(1). it should handle about 7 psi with an intercooler. Greddy is a great kit, and is already set up for the gsr motor.

 

ive run 12 psi with a 13"t and 27"l intercooler on stock internals on a customers car and havent had any trouble with it. its been running it for about 6 months now. and dont run a turbo w/o an intercooler unless you want to buy a new motor. you can pick on up off ebay dirt cheap.
