Have you considered an engine swap?

Maybe even a Cummins 4BT 4cyl diesel engine? These are in alot of delivery trucks and can be picked up with a 5speed from a wrecked truck...I've seen for under $500.

And the trunk in that car has a huge space for a WVO tank.
Perhaps a GM Ecotech XFI motor from a cobalt, or a 3800 series from a brick (those approached the 40mpg area with very carefull attention.)
