The trouble with buying special pistons is that the dish volumes are usually wrong.
You need to know the combustion chamber volume, the piston height at TDC, the gasket thickness,
They're all variables and aftermarket rods are often a slightly different length from stock, as are all the other parts.
If you don't measure, you won't know.
Whatever you think the CR is, it won't be.
I've been through the whole process with other engines in the Mitsubishi family and everything is wrong.
