anyone heard of these before? will they work on a Revup Motor? are these better than than the reg nismo cams? anyone have these installed? thnks.

 

I think you're referring to the Spec1 cams. They also have a Spec2. The Spec1 has a 272 overlap for the intake 10 degrees more than the R-tune. I don't know if you'll need new springs to use them or not. Try z1auto.com or google.

 

k k .... thnks for the info ... anyone else have these cams or know some info bout them?
