Yeppers....teg throttle cable. You have an HF right?? You'll need the spindles from the Si.......help me out here guys....the rotors maybe?? I know there were posts about this on a different thread.
Go ahead and get a new water pump, thermostat, timing belt and all of the other little maintenance stuff like that (gaskets too). those are easy to put on while the engine is still on a stand. If you have the $$ get a clutch and a lightened flywheel too.
