I have recently bought the HKS 2530 kit and would like to sale my stock turbos. I only have 59000 miles on my car. I have only put 10000 miles on the Z in the past 6 years. The car was dynoed tuned last summer (Apexi) and she put down a respectable 365hp to the wheel on pumped gas at 17psi . The turbos have a different A/R then the manual turbos. The automatic A/R is .48 which stamped on the turbo. There is very little play in the shaft. I think it's within tolerance. If you have any question please let me know. Tubos are ready to be shipped. Asking $450 or best offer.
