Starting
First and foremost is getting the cars rolling resistance down. I'd like to find some of the smaller (narrower) Civic STD rims that are fitted with the 155/80 13" tires. I think they are 5" rims instead of 5.5". I had an STD with an Si (1.6l) engine and tranny that got 40mpg no matter how I drove.
Next, I imagine that if I convert this car (89 4dr) to a 5 speed with the DX gearing and MPFI fuel injection and get the lean burn ECU from the later Y7 OBD1 engines (CX) I would think that 50+ would be no problem?
