Forgive me if this is a dumb question, but... Why would anyone ever want to go without an I/C? theres no down sides to an intercooler that i know of, is there? Whats the point of going non intercooled off the bat? Once you up the boost you'll have to add an IC and re work the piping. Atop of that ive seen PLENTY of people running ebay intercoolers (100 bucks max) well over 20psi with no problems. When they're so cheap i just dont see a reason as to why you'd go without. I know its just extra money when your trying to create a low budget build but if putting a turbo on a car with no pre made kits isnt gonna be cheap period, whats another 100 dollars?
