SouthArk is right about the balancing and blueprinting, but you do that when you are building a motor. Only worry about that then. And no, the kits do not include the thousands of dollars of supporting mods. budget half the cost of the kit for additional mods. Radiator, boost controller, gauges, and a million other little things that add up fast. Don't buy a clutch that can support FI torque levels unless you're 1000% sure you're going to do it. The clutch you need for boost will be unpleasant to drive everyday. It would be a shame to put that one in, not boost the car, and be stuck with a PITA of a clutch.
