Just a question Rex. How did you do the comp test. It sounds like you have bare motors. What was the quickest way- do you hook them up to an ECU etc.
What did you use for leakdown, or maybe I'll search on the method
Anyway I was searching this and found that the Comp ratio is pretty closely related to the cylinder comp..maybe. I found a couple of sites with turbo and N/A figures. Usually turbo model has say 8 to 1 instead of 9 to 1 and the cylinder comp considered normal was about 20 PSI lower on the turbo (low comp engine)..if I remember correctly. But then again the blue top and red top differ in comp ratio by about about the same and accoding to manual they should have same cylinder comp
Seems logical though that the 2 should be related..
My 4AGE (blue top)..stock (never had head off) had readings of 200,200,220,220. I'm not sure why so high, but I think maybe a bit of carbon build up (doesn't ping though). Can't think of anything else.
