1g-fe head skim / compression ratio - daveb948576 - 23-01-2021
has 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?

it's cheap as chips for a new engine, so try it and let us know.

i 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.

el_bandido loves his engine warning light being on so it will suit one of you either way

Would simple old school porting and polishing be less dangerous? There is plenty to remove, ike engineering did that to a head a while ago. Not sure on results as it went in a turbo car.
