Sorry I forgot to mention that I have summer tires already. I've got S03's on Rota Tarmacs. I'm trading in an 02RS for an 01RS. The only thing I'm keeping from the 02RS is the headunit (Alpine), amp (kenwood), woofer (kenwood), and the shift knob (titanium).
Shop around. There are nice options out there for 1500.
Clutch + Lightweight Flywheel + shifter kit = 1000
This is a hidden mod but would give the car a nice driving feel and would improve acceleration. Awesome if you don't have to pay someone for the install.
Maybe some STI transmission and STI engine mounts = 200
