you might want to have the rotating assembly ballanced.


and dude at 7k your simply not doing anything but floating valves. the only way id take a 22r that hight is if it was an lc engineering pro race engine. and that would be on accident. that kind of rpms is not good for these engines and is not nescessary and is really pointless. but its your money. if you want power look in to the lexus v8 swap. or a supra swap.
