Listen Up!!!!!
If you are serious about a 911 engine, there is a guy selling one with i think 32K miles on it, he's selling it for 5000 obo.... it's a 3.2 liter flat 6. it would defintly fit in there and would be a huge performance boost. just lettin you know, again it's in the 911 forum and personally if the engine is good i think it'd be a good deal if you end up buying at least one of those 914's
