  • VG33E max bore piston options

    This thread states on page 1 that a VG33E could be bored out to 99mm safely for use with a turbo:

    However the limiting factor for us cheapskate Z31 drivers (that includes me!!!) was finding a piston that would work that wasn't cost prohibitive. Has anyone looked at the 98mm piston out of a VK56DE?

    from club titan:

    Thoughts???? It looks like it uses the same wrist pin as the W series and VG30DE. Am I missing something?

    Is this a cheap option?

    from the white paper I saw, it's a dish design based off of the VH45, which is a proven overbore piston for the VG33E

    $900 will get you a custom set of forged pistons built to whatever mythical ideas you have about your VG33E. Pick up a set of rods too, OEM and crap have a way of making an exit through the block.

    enjoy building it yourself.
    if it fails, fuck it.
    at least you gave it a whirl.
