Skim them by 40thou and you will get a 8.2:1 compresion but dont run any more than 1bar of boost

For the 2 litre you have to either get a comp plate, skim the piston 50 thou???? i think or buy low comp pistons or search for a set of calibra pistons/celica gt4.
Note if you skim the piston i don't think you can run any more than 14-15psi.
