Well it depends by what yo umean by restore
If you are going the whole hog look into welding classes.

Please be aware welding is actually harder than it looks and if you are doing structural work best to get someone who knows what they are doing to look over it as well.

Secondly, as I believe they have A series engines, armed with a Haynes manual you should be able to figure stuff out pretty easily.

Oh and join a classic mini club. Seriously the help you will be able to get from people who will have already done whatever you are planning to do is invaluable.

Edit: Oh and get some decent imperial (wait how old are we talking...) tools! Halfords have a pretty good range but you will be up against years of rust so fork out for a decent all metal socket set.
