This is a modification we’ve been talking about for quite some time at 1320, but unfortunately it’s been on that long list of to dos with a whole lot of other stuff!
So it was so nice when a customer aka Richard22b on Mini2.com rang up for a gearbox for his One but really liked the idea of fitting a 6spd and an Exedy flywheel / clutch combo.

We have tried breaking our 6speed on the 1320 car for the last 160 runs at the drags strip, without any success, so we knew it made perfect sense to replace a known weak link with a seemingly ‘unbreakable’ one.
Test driving the car I was surprised how it had been transformed. This is how they should have left the factory – FUN, FUN, FUN! 1st gear is now a little taller so the 1st to 2nd rpm drop had improved. The old One’s 3rd gear has been replaced with 3rd and 4th in the S box so keeping it in the power band. It also cruises very comfortably at a respectable speed in 6th – the car was a joy to drive.

I would like to thank Richard as our first customer for this conversion and Steve Rogers at Exedy Europe for his help with this project.

So if you’re looking for an upgrade or if your gearbox has just given up we can supply all the parts for you to do it yourself via our USA partners Fireballed Racing.

We will be posting some pics on our web site next week

 

that is seriously awesome, great job guys

 

Most excellent!!!!!

 

One cool thing is that bent valve stem hooked in the dowel and the other end indexed in the starter ring gear to hold the flywheel.

 

You know whats even cooler is that valve run a 12.16 1/4 mile. Well spotted though.

 

is it correct that you used this transmission: http://www.realoem.com/bmw/showparts...14&hg=23&fg=05

What One was it? Prefacelift or Facelift?
Did you have to change the flywheel or the cluth? Does the standard cooper flywheel und clutch fit the Cooper S 6-speed-box? So is it possible to just pull off the 5-speed and put on the 6-speed box? Or are there any other mods?

I have a One built '02 prefacelift and I would like to swap the transmission, but until now I didn't want to buy a 6-speed because I didn't knew if it fits.

Sorry for my bad english,
Patrik

 

i would like to do this!! if only money and time allowed

 

You can fit eiher gearbox it just so happen that this was a pre July 04 gearbox.

You have to change the flywheel, clutch.gearbox. driveshafts.gearstick & cables,N/S gearbox mount.
