8200 max
they can spin harder but the rev limiter will bust the oil pump.
i mist a gear in my 170000km 32gtr with a blitz access ecu it hit 8878 on the multi checker!!!!! it has hapend 3 times now
i put it to the fact that the revlimit doest bounce the crank back and forth
on my other motor
(revalant mods to this topic,n1 oil pump 33 engine)
it saw 8200 regulary whist wheelspinning :lol:
it cut a long story short i rebuilt it after a turbo falure and the pump had copped a pounding!!, quite alot of ware around the pump drive surface
