Hi guys, i have Z20LET engine running on vauxhall cavalier Is that any idea if i bought Head gasket thicker than the std
for example from 8.8:1 to 8.5:1 and use aftermarket ECU management to upgrade the performance with the same standard turbine (stock Z20LET turbine)
is that will make the engine week or not because decompressing the ratio?
and what is the right thickness upgrade for head gasket..?
so.. leave it standard or going to lower the compression ?
finally, what the power i will gain (almost) for that upgrade if i decompressed the compression - note: with the same std pistons, rods, crank
