I moded my 2nd generation saturn: I still get 50 mpg, with the boat tail off. I would say anything in the back deck would be almost useless since, the rear glass is at a bad angle. How about a camel back?
The MP2 trans 1998 and after have the best fifth gear ratios. Ive read that the cruse doesn't work with the trans swap, maybe thats only the obd2s.
Putting a diode on MAP sensor on the dual cam engines will give it more low end torque.
