280zjoel Posted June 8, 2008 Share Posted June 8, 2008 "Sr20DET compression should be around 170psi (highest) and 130ish/140ish as long as each cylinder is within 5% of each other". i found this on a nissan forum, here is the link. http://www.nissanforums.com/forced-induction-nitrous-oxide/4575-normal-compression-sr20det.html hope this helps Quote Link to comment Share on other sites More sharing options...

silverarrow27 Posted August 6, 2008 Share Posted August 6, 2008 For future reference per fsm, max compression is 156 psi and minimum is 126 psi. Quote Link to comment Share on other sites More sharing options...
