I just got a stage 2 upgraded valve body installed in my Altima V6 which has the same VQ35 motor in it and works wonders. I should be running a mid 13 now with my car from the faster shifts. Jeff at Maximum Tuning also installs them for G35's has he been working on Nissans for quite some time. Anyone interested in these valve bodies can e-mail me for more information or contact him -- just mention my name and he'll give you a great deal.

 

Mid 13's? What else do you have in there?

How much is this valve body upgrade going for and how much HP is it rated for?

Thanks.
