What is the lowest comperssion ratio I can get witha 99 3.0 L? How can I acheive other than cutting into the piston or head (becuase thats a pretty dumb idea anyway) or double stacking the gaskets (which if you do it wrong can lead to bad results)


Is there a head out there that will bolt up to it... or what?


What is the stock CR anyway? (Man I wish that search button on top was working, or I had money to donate)

 

Compression ratio on VQ30 is 10:1 Leave it as is, what exactly are you trying to do? It's even boost friendly considering it's high.

 

sorry, not my car, Im just his own personal Mechanic. I do the research and the work (you know, the more fun part IMO ) Im used to my VWs and the 6:1, 8:1, and 10.1:1 CRs running my 87 oct and 32 lbs boost

 

Opps, not those two together. haha.
