Indeed I am!!!!!!! I got confused with the rb25 which is best at 0 as per SK post below....
Great thread guys.
I just need to clear something up here, I have used the Tomei 256/260 Poncams in 2 X RB25's, one Neo in an R34GTT and one non Neo in an R33 GTST. Neither of them benefitted from having an adjustable exhaust camshaft pulley, they both made their best average power at zero degrees adjustment. The Poncams work very well with the VVT, I kept it, so no adjustable inlet camshaft pulley.
This has not been my experience with GTR's, they ALWAYS benefit from adjustable inlet and exhaust camshaft pulleys. The more extensive the mods, the more they benefit and no two engines are the same.
Hope that clarifies:cheers:
BUT, how many times do you feel happier when youre told youre wrong...time to make some timing changes and pay attention to the car.
