    Hi All
    I'm after a bit of advice on doing an m20 flywheel conversion on an m52 2.8, With this conversion the lip on the flywheel fouls against the sup i was wondering if there would be an issue with using the 5mm thick shim from an auto box. The only issue with using one of these that i can see is there's no dowel to aid in keeping the flywheel centered.

    I was also wondering if i were to space out the flywheel if this would allow me to use a non e21 release bearing as i know that an e21 release has to be used i have also heard of people modifying the fork to run a non e21 release bearings but i can find any write ups on how to do this.

    Bellow is a diagram of how the shim(part 3) was used in an auto setup and some a pic of it on my engine

    Any Advice would be appreciated

    Just machine it, you don't need to use an e21 bearing anyway.

    The auto shims have 1 bigger hole to allow a dowl to pass through

    Hi thanks for this, another thing i wondered is that if i used the auto shim it makes it so that the flywheel doesn't sit fully on the lip would this be an issue?
