No internal work. Heck, the only bolt on I have on the engine besides the procharger is longtubes. Your kit will come with a chip but I would recommend getting tuned on a dyno before you ever romp on it. My car ran pretty good with the tune they sent me but I've read in these forums where some folks rides didn't run at all. If they sent you a bad tune it could damage your engine in no time. With a good tune though, you should be good to go on the stock internals. The kit will come with an 8 pound pulley. They told me it wasn't super safe to run anymore than that on the stock internals but I bumped mine up to 10 anyway about 6 months ago. The kits don't come with a fuel pump but I would recommend getting one for a svt focus and get the 42 lb injectors. They will tell you that you don't have to have injectors for the 8 psi kit but you do. My car wouldn't even start with the stock injectors.
