Atiracing.com for 09-14 370z's. Now if we could get a group buy on those Billet gears from cjm.

Ain't going to happen. Talking with phunk, the oil pump is dead. In the discussion. The Nismo pump is fine. The problem is the crankshaft. I believe harmonics play a major roll. Right about 8500 or so rpms. The crank may be going through a critical phase. Harmonics will turn a solid shaft into a flexible shaft. When it's in the flexible phase. Bad things will happen if left at that rpm too long. That's why BJ racecar runs a billet crank for this year. Last year, they was changing cranks after each race because of cracking.

So do you think with the nismo oil pump and the ati damper, the motor could hold together at 8,000 rpms just fine for 20 mintue road racing sessions?

Keep the engine temp down with oil cooler, and get an oil pressure gauge, preferably with a light indicator so that you can catch your oil pressure drop be4 its to late, if anything bad happeneds.
