M54 To S54
Hi guys my name is robert and i own a 330ci 5spd. The car is a 2001 BMW that i just bought about 3 weeks ago. I am glad to be apart of the BMW family, but i don't have the exact car i wanted. My intentions were to Buy a M3 but i ended up buying a 330ci. What can you guys give me on helping me do a motor swap?
