Guest Anonymous Posted March 24, 2003 Share Posted March 24, 2003 I want to use it (p90) on the turbo motor I'm puttin' together. I have some cam tower shims (.030 I think) from another head. If I mill the head .030, appx. what will I wind up with for a C.R. with stock turbo pistons ? Anyone done this? Also what is the origional turbo motor C.R.? Is it 7.4 to 1 or 7.8 to 1 or something else? Thanks in advance for any and all help! Cheers, Mike. Quote Link to comment Share on other sites More sharing options...
