Naturally Aspirated. I like to look as legal as possible living here in california. Having an impounded vehicle is not my idea of a good time. unless the laws change it's NA all the way...

 

I know that reving higher would be able to produce quite a bit more power, but what I'm thinking is that I would do the crank and then do the head work a few months later, after my bank account has rebounded.

I would probably follow it up with BC264's and an uprated valvetrain. Although I have heard that the 264's won't pass CA Smog, so maybe just the valvetrain.

 

PDM's cams are a bit more pricey but they were proven to extend the power band better than the NISMO's and the BC stage 2's. The PDM's would work better for extended rev as they are designed as a high rev cams.
