Thermostat Question

And how you drive.

[CIVICLX93]

what is the difference with the different trannies and the p28?

nah, i drive pretty nice. I don't like to waste my gas considering i drive to school and to work and there both pretty far away

the p28 is the vtec ecu and it comes with the d16z6 which should be in my 93 civic ex but i tihnk i got maybe a 90 or 91 d15b7. So i dont think im ever going to get better gas mileage unless i do a swap. i heard the b series give you better gas mileage considering they have more horsepower and it's easier for them to get to that 5th gear.

The longer the gears, the better the gas mileage. For the 5th gen civics, from longest to shortest, CX/VX (the same gearing I believe), DX/LX, Si/EX. However the longer the gears, the less acceleration you will get. So there is somewhat of a trade off between fuel economy and performance.

The d15b7 only came in the '92-'95 civics, you sure about the engine code? But the B-series will give you less mpg, because they are bigger engines and have more power. The bigger the engine and the more power it makes, the more gas it needs to run. Even the B18b1 (Integra LS, RS, ang GS engine) only has 140hp and the longest gears of any b-series transmission, but it will use more gas than any D-series engine (regardless of transmission). And 5th gear doesn't mean anything really. As long as you're in a high enough gear that the car isn't bogging (caused by being in too high of a gear), you'll be getting the best mpg possible.

what was the engine codes that came in the 90 - 91 civics? I'm pretty sure mine is a d15b7 but it doesnt look like any other d15b7 that i have seen in like a DX/LX or maybe a VX/CX. I'm not totally sure though.
