Well, my mom's Cherokee with this engine and a 5 speed (2WD) gets 
about 20-22 regularly in a mix of city annd highway driving.  That's 
with 190 hp, I tell you that Jeep with the 5 speed will smoke about 
95% of all cars on the road.  I have beaten Mustang GTs in it.  It 
may even run with my Z.  I think this engine may be the way to go 
for you.  This is a great engine.

This may also be a good option, I don't know.  I think the 4.0 HO 
6cyl would be your best bet if you can get one.  The mpg with a 
supercharger on a 2.5L four is not going to beat the big 6 by much, 
if any, and the 4.0 will certainly last longer than a blown 4 banger. 
 I think it would be interesting, for sure, but probably not the best 
option IMHO.

Good luck, anyway, and let me know what you come up with :)  A 
supercharger on my BMW might be just what the Dr. ordered :)

Later-
