I just picked up a 94 civic ex 2door coupe, and it needed quite a bit of maintenance. So far, I've replaced:

Timing Belt
Water Pump
AC Condenser
2x Axels
all 3 accessory belts
spark plugs & wires
engine mounts
alternator
brake pads & rotors
4x tires

The car runs great, and i'm getting it professionally painted at the moment.

I am just using it for a commuter car, any suggestions on increasing mpg's? or any other major parts that should be replaced at 150k miles, that I did not?
