My 89 wagon is only a 5 speed 2 wheel drive, with the 1.5 L DPFI fuel system.
I would have liked to get the 4 wheel drive, with the 6 speed, but I was primarily looking for something with 4 door's and that would get reasonably decent mileage. Iit was getting to be really the pit's everytime I bought gas because it seemed like I had just visited their so recently. In looking at epa ratings as a reference point, the 4 wheel drive model seemed to get 27, at best, while the 2 wheel drive seemed to be capable of getting more like 32, from what I recall.
Like all of you, I think, my budget is tight already and here in Ventura gas was at $3.39 over last weekend and it's now back down to $3.29.
I've thought about the 6 speed because of the granny gear, but the overall output has the engine running at a pretty high rpm, even in 5th gear. From what I've read here and what I've experienced, it seem's that as a general rule, the lower the rpm you can get away with and still move forward, the better your mileage is going to be, so for now I am using what I've got and just trying to get the most out of it I can.
Have you finished wiring up your new motor and transmission, yet?
