23-01-2021, 09:41 PM #1has anyone skimmed the head a lot to increase the compression ratio of the N/A engine? i'm think about taking about 1mm off the head haha... i know the risks as i've done it to other cars, just want to know if anyone else has tried it on the 1g-fe?

23-01-2021, 10:24 PM #3i think my head gasket has gone anyway so it needs to come apart, i'll attempt 0.762mm off the head which is 30thou, i don't mind trying it. i'll check the valve clearance first and also the camshaft timing might be off a little bit i just hope it's not enough to show a fault on the ecu. i don't like engine lights being on.

not as fun though!

any ideas what the dynamic compression ratio is?
