I've searched, but have got mixed answers/parts

I've got the opportunity to get a running manual E32 735i (MOT failure) so the obvious choice is to chuck the M30 in the tourer

So, what do I need, where do find the parts (that wont be on the E32) and roughly how much am I looking at to do this??
Sorry, no doubt this has been covered a million times.
Cheers,
Ed
And while I'm here, does anyone have a link to details about the E36 steering rack conversion??
