Jimmy's right...the stock valvetrain on an ITR is not ment to be rev'd to 9200. The valves and springs will be the first to go and as a result you could pop a piston. If you have the old P73 ECU I would highly recommend you pu that back in until you upgrade your cams, cam gears, valves, and springs. Depending upon what you get it can be very costly to do...Skunk2 and Toda are two good companies to go with.
