Thanks for the good advice.
There are certainly lots of cars on ebay so I've started my 'market research'
Do you know if i'll need a new/modified propshaft and do you think the e30 diff would take the 190bhp?
I might have too look for some 325i rear hubs/disk brakes as well because I fitted the old drums from my 320i (although they do work rather well!)
thanks, Peter
