You can't run 20psi on a stock block 370z like you can on the Sti or Evo. Those cars have a low compression 8.5:1 ratio made for boosting. The Z

You can't run 20psi on a stock block 370z like you can on the Sti or Evo. Those cars have a low compression 8.5:1 ratio made for boosting. The Z I think is 11:1 ratio. With high compression your are already generating alot of heat and adding an additional 20psi is going to blow the VQ37 to kingdomcome. I think the most boost you can run on the VQ37 from what I've read is around 8psi max on 93 oct. and that's considered high. When I had my Evo I was running 22psi daily driven and 24psi when in race mode all on 93octane.hehe.
