ZE standard bore size needed

  • admin

    Hi all,

    Does anyone know what the standard KL-ZE piston bore size is?

    I'm trying to order Wiseco pistons and they need to know it.

    Failing that I'm going to have to pull the engine early which will be a pain in the ass!



  • 84.5mm

    Sounds like a serious build! What rods you using?

    Cheers mate, think I'm going to pull it anyway as I never opened the engine when I got it, who knows if it was re-bored!

    Best to check before I fork out I guess.

    Yep its looking like a full valvetrain/drivetrain upgrade, so I have been recommended H-Beam forged rods, there good to 800hp apparently so that more then suits my requirements.
