Hi guys, My first car was a R53 Cooper (JCW body kit and alloys) and I absolutely loved it.
Moving on a few years and moving out with a few mates who are all into cars as well, I wanted to do an R53 ‘super cooper’

Stupid plans for it including full rebuild, twin charge (someones gotta do it), and all the necessary exterior mods. My worry is the transmission. I hope to push to 550bhp+ (if that’s insane please call me out and give me better figures)
I’ve found drive shafts rated for 475bhp - would they last if I was running more than that?
I’m hoping to get a gearbox rebuilt but I’m not sure what would need doing (aware about the clutch, flywheel, and diff)

Any suggestions for anything would be extremely helpful, wouldn’t say money is an issue as I plan on keeping it through the electric revolution


(if you wanna see my old car and my inspiration go to Instagram and look for #sirgeraldthethird ??)
