I have a clubman, so it seems a waste not to use the extra space in the engine bay. What cost would a turbo build be?
What's involved and how much would a novice like myself be able to do myself?
Cheers

check out turbo mini forum, that'll give you ideas!

Likely to be fairly high CR then.
As all the sucky blowy holes are facing the bulkhead the situation's pretty much the same with all Minis.
If you don't want to cut chunks out of that pristine bodywork, you'd be best off with something like a GT17 blower on a Mirage Manifold. There'll be plenty more to sort though, a whole fuel system, suitable ignition....
At least you've space for an intercooler and even a front facing radiator.

if you just want to get to around 100hp that is pretty doable with your current engine as long as its not shagged and the rings are leaky....
You Will need to find out the compression ratio, or be prepared to pull the head and measure the piston dish and head dish. after that, the below applys
get the compression ratio down to something that will allow some boost to be fed in, if you are staying low boost with modern fuels you can go as high as 9.5:1 ( i have head of as high as 10:1 on mapped ignition)
best way to get the compression down is to have the head chambers taken out larger ( or swap the head)
the next biggest problem is a suitable cam, you don't want anything too hot, the Evo 1 will work as a performance turbo cam, but itsprobably as hot as you would want to go with a turbo ( dont run 1.5 rockers)
you will want an uprated diff, as a minimum i would suggest an X pin dif ( you may have one fitted already, the rest of the gearset will be ok as long as its in good condition.
Ok that covers the main Issues.... onto the actual turbo fitment.
the Metro turbo setup wont fit unless you cut the bulkhead, but you can use a fusion fabrications manifold with a GT17 from a saab which will fit with no body mods, then you need a turbo carb setup ( or a NA carb thats been converted)
plumb all that in with a 2" exhaust system ( maniflow do one of the shelf), and also fit an intercooler while your at it.... its simppy not worth not fitting one especially in a clubman. any intercooler that you can wege in there will be fine... bigger is better.
You will need a High pressure fuel pump and Metro turbo fuel regulator. you can use a generic external fuel injection pump a return feed to the tank will need to be fitted. Using the MPI tank makes this neater as it already has a suitable pump, and a return inlet.
ignition.... you will need to change the advance setup with a recurved dizzy... or better still fit a mapped igntion system...
most importantly get it set up on a rolling road... many people have skipped this step and and trashed the engine in the process

That's a great bit of info, I really wouldn't want to cut the bulkhead. I'll have to do my homework for sure, cheers

go for gt17 saab turbo and fusion fabrication manifold that's what i have and no need to cut bulkhead. only part hard to find seem to be turbo carbs with locking ring around dashpot. if you get a full tubo engine then can keep your n/a one as spare and probably save money in long run.

You can convert a Hif to turbo spec. The clamp's belt & braces really, the important bits are the throttle seals Float & float valve. Even hifs are getting expensive to find, so you could look at programmable injection as a "gateway" mod. You'd be halfway there with programmable ignition and both are worthwhile mods in their own right to add oomph to a road car.
....of course injection would be so much easier with 7 (or more) ports
