I just purchased a 2003 S2000. It’s a blast so far. The car is stock as far as I know except for a gutted cat, which I did and spaced out the O2 sensor as I had a CEL. I am wanting to keep it mostly stock for now and just trying to get a Billman TCT as I hear this is a good preventative measure. I have a few tranny noises, I may have some bearings in there replaced at some point but clutch and gears “feel” fine.
