Cossie compression 0.5mm 4x4 pistons on 2WD head
Like the tittle sugests, I've got 0.5mm 4x4 pistons on 2WD head.
I'm sure I have it too rich and was a bit worried about bore wash.
Just checked the compression and got 120psi on all cylinders on a cold test. Did the wet test and it jumped to 140psi.
Is this ok for oversize 0,5mm 4x4 pistons on a 2wd head? The compression ratio is lower from what I know.
Is it time to go open heart surgery or it should last a bit longer?
Thanks. André

Hi Graham
Any idea what I should be getting with the 4x4 pistons on the 2WD head with it warm?
I'll try to do the test next weekend I don't have the car with me right now. It's getting a new clutch
