Rb20 Compression Results

[monaroman76]

Hey guys just finsished doing a compression test on my rb20det, results were:

139

140

132

138

139

139

I got these results on a slightly warm motor but not at running temp.. would this likely affect the results much?

From what i have read on this forum they sound reasonable to me, but just wanted to double check as i am looking at a turbo and injector upgrade in the near future, and didnt want to waste my money if my engine was unhealthy.

Cheers.

They are fairly alright results, except for cylinder no:3, its seems a bit too low and its a big difference to the other cylinders. I know because my rb20 had around 130 in all six cylinders & lasted me 2weeks before i lost all power:(..and died.

I thought as long as they were all within 10% it was okay? Mine are all within 5%..

20yr old motor - good result IMO.

Just showing its age more than anything else, its ageing gracefully

LOL, before all my next round of mods i want to get some oil analysis done and do a compression test to see hwo things are going. I hope i can keep them all within 5-10% of one another
