Guest bastaad525 Posted August 16, 2003 Share Posted August 16, 2003 okay I did a search on this one using "compression" "compression test" and "compression check" and didn't find anything... I just want to know what are good compression #'s for an '81 turbo motor? I might test it today just for the heck of it. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted August 16, 2003 Share Posted August 16, 2003 mine were 145psi aross. 7.8:1 static compression. as long as it's more than 100-110psi, you should be good. IMO Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted August 16, 2003 Share Posted August 16, 2003 My last turbo engine had 100-105 across all cylinders, and it ran well with no oil burning. The rebuilt low mileage engine I have now tested 125 across all cylinders. As long as you have less than 10 psi between, you should be good to go. By the way, I think compression test pressures are lower at altitude (I'm at 5280'). Quote Link to comment Share on other sites More sharing options...
