Compression

[4u2nv]

Dose any one what the standard compression should be on the gt please

[sabre]

Gt1 should be around 140-150 roughly gt3 I believe 160-180

Thanks pal. My rings are gone for sure cylinder 1,3,4 are around 90 and cylinder 2 is between 70-75 engine rebuild I think so

a GT 2 is the same as gt1?

[sabre]

a GT2 can be a GT1 or a GT3 can tell by the idle control valve on the rocker cover (GT1) on the inlet (GT3)

You can't actually tell if it's been played about with, mines a gt3 but I'm using gt1 inlet an icv so to anyone's eye it's a gt1

[sabre]

There are ways to tell the difference if you strip the engine down from what I have read

Yeah heads are different an pistons sit out slightly different too

Quick check would be on the ECU numbers. But as mentioned, if the head or pistons have been changed for a different type then the compression would be different!

1. 93-95 without immo code, ECU 099
2. 95-97 with immo code, ECU 841
3. 97-99 with immo code, ECU 159
