  9. Hi, I was wondering if you guys would be able to make a 2.5mm over for a silvertop 20v

  10. are the 20 valve 4ag turbo pistons, a direct replacement for the stock units,( minus the compression change) i mean do the wrist pins press in or are they floating??


    These pistons are .5mm over size (.020″) and have full-floating wrist pins.
