Thicker Head Gasket Lower Compression For Turbo?

[Brendan430]

Can i lower my compression a little bit by using a thicker head gasket on my 92 325is? because i dont want to buy new pistons for the turbo im getting. Stock setting my the turbo is 6psi. I weould like 7psi maybe 8psi..possible/?


thanks, brendan

i did that on my acura when i turbocharged it. It worked pretty well. Good for scratch built turbo. BUT.....i am really not sure if this would work for German vehicles. Theory is the same, but not sure......


Hope someone can give you the answer.

yes it will lower the compression with a thicker head gasket

8 psi and you should be fine.

Anything over that and you should start looking into a 3mm head gasket.
