well i would replace the engine rotors, stationary gears, counter weights, and apex seals.
www.racingbeat.com has a good set of light weight rotors and everything else you need. if you get the rotors and carbon apex seals you'll redline at 8500 rpm's and if you get the super light weight rotors you'll redline at 9500 to 10000 rpm's. its a bit pricy but its worth it.
but if you get the super lightweight rotors it would be best if you milled them for 3mm apex seals, and replace your flywheel, clutch, stationary gears, the counter weights come with the rotors. and since your rebuilding and you do this you can also buy a porting template and clean your housings so you dont have to buy new ones for the rotors. but this is really for a die hard race car... but man would you be a billy bada$$ out on the road if you had this done
