If you get a full metal piston would you then need to upgrade your housing to metal as well?
if you have 18:1 gears do you want 13 or 14 teeth on your piston? Or does it matter and what would that extra tooth do for it.
And some tech was saying that CNC gears you need to dremil them down to fit inside a gearbox housing?
Has anyone else had this experience, or do they just go right in and then shim away?
