If you come up with a TDI motor, I'll give you the 2.4 in my Caravan. It has less than 100,000 miles on it, but has a slight rod tap when it's cold.
I'm not joking, either. Of course, you'll have to come get it and drop off the TDI... lol.
I'd actually consider a swap for any 3 or 4 cylinder automotive diesel engine, whether it's legal for emissions or not. (We don't have emissions testing here, so if you don't get caught, it's not a problem.)
