i have just bought a subaru impreza type r 2-door. its a 1997 and has the pre facelift dash. i think its a version 4. the bottom end is knocking on the engine and i have been offered some forged pistons quite cheap. the bore size on the pistons is 93mm but im not sure if these will fit. anybody knows???

it would be a great help

Std bore is 92mm, 93mm pistons are oversize(as are 92.5) and the block would have to rebored and honed to suit-cost circa £100.
