    I believe the general consensus is to stick with OEM pistons regardless if you are moding or not. It seems it is only worth while to go Wiseco if it is a racing application as the motors built with them seem to be finicky unless broken in correctly.

    You will need to run larger clearance with the Wisecos so boring and replating would be required,

    Wiseco has aquired ProX some time back, ProX or OEM works...
