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?

 

fuel filter!!!!

 

Put about 2-3 extra psi of air in the tires for less rolling resistance.
Lighten up the car (remove unnecessary items).
Get a lightweight battery
Lighter wheels

 

Fuel filter, good call...

Yeah, I was thinking of getting different rims, what would be a good idea for size? Or should I just get like a set of VX rims or something?

 

Is it worth it to get the VX rims, they are only 13''... but will it help?

 

thermostat. If it is stuck open your MPG will suffer, especially when it is cold out.

 

Glad I caught this thread, I myself am doing work on a 92' civic. Just had the brake calipers replaced. I'll also be replacing a Omni Power adjustable damping full body coilover thats busted on the front passenger side. I think Omni will sell me a replacement, I hope. Didn't think of the fuel filter until I saw this, so I'll put that on my next list of item to replace. Any suggestions for a good fuel filter?
