    Oversize Pistons RXP

    Who does oversize pistions for the RXP - larger than Genuine .5
    I have a block where all three holes are bored to .5 and need to go to .75 or there abouts. The ski runs a turbo setup (18psi) so I dont want to have thin cylinder walls.

    Read the specs, but, you should go max piston clearance on a turbo.. I think Min, clear is .0025 max clear is .004 You might be OK With the heat of a turbo the piston expands more and can benifit from extra clearance.
