How much have you invested in your car to get to where your at. If I were to trade in for and build up a Cobra I'd lookin to get down into the mid to high 10s. The key thing is I wanna keep her streetable, meaning minimal race fuel, can be setup to pass emmisions with ease, and no overheating(ha ha in AZ). The turbo setups to make tremendous power but most seem to require a new K-member. Is this just a fact of life or do some kits get away with using the stock K-member.
