Research your clutches carefully especially how they work with the stock slave cylinder. It's a job you only want to do once.

also depends on how you drive it

the stock clutch can live at 400+ if your not beating on the car, if your gonna track it, you'll need to replace it sooner rather than later

FW is fine for bigger numbers

well i dont plan on tracking the car more then a coulpe times if even that. but it needs to hold up as far as the street goes.... i meen i enjoy goose'n it out of a red light once in awhile and if i have too a race here or there depending on what pulls next to me.... im not sure what you would call that kinda driving, but im guessin its a mild beatin on...... i did say 450whp but im lookin at the v3 vortech non intercool kit from brenspeed. a guy claims he made 420whp 381wt with shorty heads, hi flow cats, muff deletes which is pretty much what ill have too. with those #'s and goals what do u guys think now? anyway thanx stkjock for your IMO

If someone was asking for advice I would steer them toward the rst. It costs more but it's better to spend the money the first time and only cry once.
thanx again... going to keep that in mind. how about the stock flywheel? did u have to change that? im sure that can handle 400-500whp.....
