Those are three things that will need to be upgraded to get the most from Templars SC kit, or any FI kit, for that matter. You could also get some good tires on there, and do some suspension work. Either a full coil-over setup, or maybe just a bigger rear swaybar, solid endlinks, and strut tower braces. Oh, and the SC kit will probably also need a fuel computer, and everyone seems to go with the APEXi S-AFC, so I guess you could get one of those, install it, and get familiar with it, so you know how to use it when Templar gets that kit out. Ayways, he talks about some of the upgrades that will/might be needed, and the ones you mentioned should do good. He did suggest staying away from the ACT clutch setup, too much grip. Unless you get a strengthened gearset for your tranny, which is something I'd really like to get before the SC goes on, but don't know if I want to spend $2k plus on the tranny if I don't have to. Anyways, guess i shopuld stop typing now, my hands are getting sore! Hope this helped!New exhaust sys? Clutch? Fuel system upgrade?
