Over on Z1auto.com they have listed alot of new internals for the Z. They have Spec 1 and Spec 2 cams and Nismo VTC. I was considering getting the Spec 1 cam but was told that this cam (276 degress duration) wouldnt work with our Z's due to the ECU. And also how could that Nismo VTC help out with Stock or either Nismo R-Tune cams. Looks like I have to settle for those. Here is the link to the website.
