so I recently acquired a 5speed box with out knowing (didn't even test it, or look at it, bought a bunch of ke70 parts and it was chucked in with everything) turns out it is a 5speed (k50) box, pulled it apart and everything looks/feels brand new. so this gets me to why I'm writing this, I've searched around and couldn't find any info on it, I currently have a 4speed box (4speed flywheel and clutch) and was wondering if my 5speed box will bolt straight on and work fine with a 4speed flywheel and clutch or does a 5speed require a different flywheel and clutch? please help haha cars got to have the motor back in it soon.

If its going into a KE70 it will bolt right in.

yea its going into a ke70 cheers heaps man this has been a huge help!

You will however require the 5 speed shifter (and possibly clutch fork?) so worth checking you have it (them).

Nope. Ke70 ones are compatible between 4 and 5 speed.

Aha!
