this threads kinda old now but i do want to say im thoroughly disappointed that you decided for an engine swap instead of a turbo install
I really want to see someone successfully install a turbo on an N12 :p
ah well, good luck with the swap

Its very possible and a good idea. Cause it has a spare tire. :-)
Big thing is to lower compression to allow for added compression of turbo. Upgrading crank, cam and valves also. Then there is the location. Battery will have to be moved. Ecu, fuel management...
Jay Leno has 2 engines in his cooper. Anything can be done!

I think you're better off selling your base model and buying an S. It will be easier to change out the turbo from the S and upgrade to a twin or just to a larger size. You won't have to replace 90% of your car's power plant and you can still get tuned to the 300 horses that you wanted. It will be less expensive and easier in the end.
The R56 Justa uses a 6-speed Getrag. Not a 5-speed

i wondered if using the base head/manifold would be better for making big power on an already turbo mini
should drop on and eliminate DI? can the injectors even be swapped - cant find where they even mount looking at pics
