Im just about to breath life in a 91 cooper with a 998 on single carb (dont ask, it was done prior to me buying the car). I've owned the car for around 5 years and have had it dry stored for about 2 due to life commitments. Now feels right to start getting my hands dirty. im looking to swap out the engine for a 1380 or 1275, upgrade the brakes and suspensions. where the best place start looking for parts? also any advise on the best way forward, i.e, brands etc would be much appricated.
