I am looking at getting an s2k, and have been looking around getting an idea of what I may do to it, just wondering who make the best, most power, intak, header, and exhaust. and it there are any other things I can do for a little more power.
Your question is n/a tuning, so why is there a supercharger picture.
Don't count on getting a lot of extra power from minor upgrade such as intake or exhaust, the only different you'll notice are the sound.
Unless you have 5G to pull out for Comptech Supercharger, but we're are focusing on N/A, right?
Well, IMO, the best mods for a NA S2000 is to go away from NA and move to FI. Best bang for the buck. If the post said 'best mods for a SC S2000' I'd say smaller pulley, bigger injectors, Emanage.
Waste of money? It depends on your goals, I guess. There is fun in modding a car to make it unique, make it sound or look a different than everyone else's. To some, that is money well spent, even if it isn't backed up by performance figures. If your goals are to pull 10 car lengths on stock S2000's, then it probably is a waste of money.
