Rb20det Compression Test Results

[chrishelliwell33]

hey guys, i have a r32 with rb20, i had a compresin test done last week, before i start doing anything major to my car....

results were

90 90 90 95 90 90

all cylinders are equal, but compression seems a little low... any one have any results from any other rb20's?? or any ideas as to why mine could be so low??

cheers

as long as they are within 10% of each other i wouldnt worry about it at all. they seem fine. The last RB20 i did wass a 40k import and it had 120 in all cyl's.

I wouldnt worry about it, just keep driving it

wet compression or dry compression test?

will show different results. (the variation won't change but the actual number will)

Throttle was held wide open during the test?

Gauges differ; its possible its just the gauge.

For what its worth my old rb20t when I bought the car some 6years ago had ~145 across all 6. 100,000km's later it was basically the same but with a slight variation.

it depends on the guage it seems a little low but as other have siad if the throttle was held open with will make a difference, the main thing is the vairences which seem good.

where did you get the guage from?

I've had a few supercheap guages - one read 30psi too high, and one read 50psi too low.

Tested with my air compressor.
