Also ordered Alta silicone intercooler couplings as mine have visible cracking in the stock rubber, along with a new serpentine belt.
I was eying the Alta air diverter as the intercooler to hood seals are shot, along with one of the silicone smooth intake hoses from the intake to supercharger as I suspect my original piece is getting crusty. Software was also on my list. It's had at least some of the bushings replaced with OEM so I'll probably leave it alone for the moment. Does exhaust work buy you much? Any other words of wisdom are appreciated.

I would also recommend removal of the 2% crank pulley. For one, like Nostril Cheese said, you want dampening on the crank. I went with a PRW fluiddampener unit,
Amazon.com: PRW 2510900 FluidGel Black 138mm Serpentine Standard Drive Pulley Damper for BMW Mini Cooper, 2001-2006 Gen 1, Tritec 1.6L: Automotive, when my OEM unit failed. Secondly, M7 parts (and Alta for that matter) do not have the best reputation in the MINI aftermarket.
For the intercooler boots, stick with OEM.
There are a few options for a tune, one with way more experience than the others including race MINIs and Porsches. Contact Jan at
