Anyone know the thinest gasket available for a 2 litre blacktop
think i messed up my turbo engine when put it back together
currently fitted with 8.5 compression Je pistons and a 1.4 mm gasket
which i think may have dropped compression way to low

Also if anyone is good at maths is thers anyway of working out how much i can raise compression by fitting gasket say .5mm thiner?
