hey i have a 2006 evolution 9... will evolution 8 performence uprgraded parts such as cams, cam gear, injectors, exhaust and intake and all fit on my evo 9? or will it not work cuz of the difference?

 

Cams- exhaust cam only
cam gears - again exhaust cam gear only
exhaust - a full Turbo Back exhaust will work, a cat back will also work, but you'll end up with two O2 sensor bungs (one in the stock cat & one in the cat-back) and one will have to be plugged
Intake will work, but you should research intakes first (I'll give you a hint, there is a lot of better mods to get.)
