Tork Tech kit, by the time you are done it'll be the price of a Kenne Bell 2.1L. With the price of the TT kit going up $500, the only real benefit to running it is if you want a Kenne Bell 2.8H headunit on a 2V without the Kenne Bell port 5 issue from their manifold or if you want to run a Whipple. Both of those blowers would be for built motors though.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
