#1 I've got to agree with some of the other posters about going bigger. The 3.6 and 3.8L engines have just about the same foot print as the 2.5 and 2.7L, but MUCH more power. This sounds like a very expensive project. I personally would go with a bigger engine to get the most bang for your buck.

Have you considered going air cooled instead of the newer water cooled engines? The last generation of air cooled engines are from the 993 and they were pretty powerful too, more so than the modern 2.5 and 2.7L. I'm just thinking that it might help to simplify things quite a bit to not have to worry about front mount radiators (although an oil cooler might be required). Older 911 engines are even simpler and would be an easier install. I'm not sure how much power the 901 and 915 transmissions from the MR Porsche 914 would take, but you can probably mate up a lot of the 911 engines to those transmissions for the MR layout.
