OK heres my idea. My dad has a '92 318is and his A/C is blown and will cost $1200 to fix. I own a '94 325i. My idea is to have him sell his M42 engine (prolly won't get much) and then take the engine from my 325i and put it in the 318 and then buy a 3.2 liter M50 and put that into my car. This would solve his AC problem and his lack of power and would help my lack of power (well to me its lacking
). Anyways, does anyone have any idea how much this would cost? I don't think that my dad and I have enough expirence to do it ourselves so we'd need a shop to do it. BTW the engine in my 325i has over 200k Miles but it is still very strong and was well taken care of.
