R33 Cylinder Compression Result - Advice

[dan-0]

Hey guys

I bought a 1995 R33 GTST with "78,000" lol kms on the odo. I suspect a bit of sly play there but I warmed the engine up and did a compression test dry and wet.

I know there are a few other threads out there with results but because my car came with NO service history I was hoping to get some direct advice.

DRY WET

1-155 1-159

2-152 2-161

3-145 3-159

4-145 4-160

5-140 5-162

6-147 6-170

What do you gurus make of these results?

Thanks

Dan

Very healthy engine, more than 10% variance between cylinder is generally a bad sign but not here. Nissan service manual recommand a rebuild at 120psi and brand new about 172psi (not sure if this is wet or dry).

as above, nothing to worry about with those results

if you haven't rebuilt it then it may have had a head gasket replaced and the head shaved a bit (as happens when replacing a head gasket)
