Not a bad read that. Sorry to hear everything went tits up for you but at least you're back on track now. What's the maximum output you can get from yours?
You've not wasted any time getting back into mods and I'm really glad things are looking up for you now.
As mine is a standard Cooper S, the exhaust and turbo ports are terribly matched so flow isn't great and the turbo is smaller by a few mm. Max HP on a Cooper S with similar mods to mine is about 240-250 Flywheel and about 225bhp at the wheels. Mini's suffer minimal drivetrain loss which is good
