My first engine rebuild and I'm trying to get the best gas mileage possible on a budget. Any tips to increase fuel economy on my new rebuild? And anything that I should know when rebuilding this engine? Also the car is an automatic... :(

Buy a manual.

Yep. I've owned manual and automatics both. I recommend getting a manual transmission, shift linkage, clutch pedal assembly, etc and swapping it while you have the motor out, it will be much easier. That will give you an instant 10-15 mpg boost. If you want to stick with the automatic just make sure the car is tuned up and running it's best. You could also upgrade to 13" wheels, get an economy camshaft, or a mirror delete if you want to squeeze a few more mpg from the auto.

Yea, sell the automatic and scour the countryside for an xfi version. When I was driving trucks across the states I noticed so many parked Metros/Swifts. Always wanted to stop and see them but nearly impossible for me to sight see.

Five speed for the win. Autos are notorious for sucky fuel mileage.

Best tip for automatic mpg gain is to slow down.

Thanks guys for the replies I really want to change out the trans. When I find a good replacement and also I know the auto trans doesn't get as good mpg's. But on open highway I ran a 102 mile trip and only used 2 gallons of gas. Is that normal?

Its not but then a 2 gallon sample isn't really an accurate measurement. If out can get 40mpg out of it you'd be doing good. That 3 speed non-locking trans is just not efficient.

Well hopefully I can find a 5 speed soon. What is the price range I would be looking at for a manual transmission in a junkyard? Without being ripped off...

You almost need a complete donor car. More than just a trans swap involved here. Always one or two more parts you need that you didnt get at the jy, then you go back for them or find out they just crushed it yesterday. If it was me I'd keep looking for a manual car & keep the auto one for parts. Just sayin'

Yeah I understand I guess I'll just keep looking for a donor car. I wanted to swap trans because the body is in great shape no rust anywhere/ all interior in great shape also. Solid car just trying to swap transmissions for the fuel efficiency.
