I am thinking about buying a CPT 65. I would be adding 50lbs injectors, and a 9" 3200 Art Carr non lu. I seriously doubt I would ever run more than 21lbs as the block is almost stock. My question is an aftermarket intercooler a must and can I get away with just doing the big neck to the stock intercooler? How streetable do you guys think it would be? Should I go this big on the turbo with stock heads?
