    Yes hard top only, It's not really an option to have a cage and original soft top it's either or!!

    I think I've pretty much got everything where I need it so it's time to spray the cage

    Certainly a change from last time I saw you doing stuff to your old E30. This looks like a great project, keep it up!

    That's spot on.

    Do you know how much you had to have machined off of the inlet cam?

    Yes happy with is as that's a mega safe tune, so nice and reliable , injectors are only at 65% duty so plenty more potential!

    Great build.. What parts did you use to fit the m20 flywheel? Clutch? Etc.. Did you need to modify the flywheel heard about skimming 4mm off the back?

    That is great power well done. Reading this is making me want to add a little extra to my z4. Good work :-)

    Yeah a few mm machined of the back of the flywheel to clear the sump, M20 clutch disc and pressure plate and I slightly modified the clutch arm to take up the play in the release bearing
