Machining Piston to lower compression?

[Jorgen Karlsson]

I don't like the idea of taking material of the piston in a turbo engine.
You want the piston rings as low as possible on the piston to ease the
detonation load on the rings and ring lands. The piston top shoud also be as
thick as possible to handle detonation.

I think that a call to JE pistons will be the best deal in the long run.

Or you could use a thick copper gasket to lower compression.
