| One / Cooper 5spd Midland to 6speed S Getrag Conversion
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 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.
The worst part of the job has been deciding whether this post should be under the forum heading Engine & Drivetrain Tuning / Faults and Fixes / MINI One / MINI Cooper
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 for his help with this project.
So if you’re looking for an upgrade or if your gearbox has just given up we can do the conversion for you or supply all the parts for you to do it yourself. |
