Even though you guys missed out on getting the gears, one small point to remember! You can ONLY do the exhaust cam gear on the RB25DET due to the VVT on the inlet cam gear. It "MAY" be possible to modify or adapt the stock inlet gear or even the HKS one but it would be a bugga' to do it & not worth the cost for such a small gain ( around ~5rwkw max even on a full bolt on upgraded turbos etc... RB26DETT motor). I gained roughly 10rwkw (so far) from doing the ext' gear (via 4' retard), I say so far as ECU issues caused problems @ dyno testing was unable to be completed For anyone thinking of doing this mod I suggest waiting until you have a way of over coming the stock ECU's timing retard (the cause of the dreaded RB25DET flatspot) the adj' ext' gear only makes this problem much much worse :x you gain power but you get a very poor power curve (& the car will drive poorly). Sorry to hijack the thread people, thought this info might help but.
