Yeah, I am aware that the oil pump drive's on the 32 RB26's were weak, so Nissan did strengthen them..
Maybe I'm just being a bir paranoid about buying a GTR, but I just want one that won't give me any trouble or throw a rod lol.
Now, onto the modifications you can do.
Say if you do a turbo-back exhaust (de-cat), pod filters, boost the turbo's a few pounds higher than factory and install a power-fc, how much awhp should if expect within reason on a safe tune?
