yep, rob from ZCG. i'm currently running the 3.12 pulley. I had the 2.87 on when i originally installed the kit, but rob was concerned my boost level was too high for the stock block

ooo ok... how much difference is it from 3.33 to 3.12

OP, you can also run shorter gearing in the diff.

3.70 or 4.08?

It'll give you the feel of having moar powaaaagh

but then i'll loose my top end speed rite?

yeah but who really goes 158mph on a normal basis?

yea thats true but do you know how much you loose on top end?

I'd check My350z for that one. There aren't too many G owners that have changed out differentials.

A lot of Z owners have though.

But my guess would be 8-10 mph

2-3 psi of boost depending on your mods.

kool ima ask rob to see what pulleys i got and if i can go to next one...

Chris wat mods do u have?
