Re: trying to make my 91civic si get more mpg?
you can do your basic intake/exhaust, change the air filter/plugs, etc. If you really want better gas mileage look into the d15b7 engine I believe. It's non-vtec and i've heard of people getting over 40mpg with it.

Re: trying to make my 91civic si get more mpg?
No, I'm pretty sure using smaller injectors and the different ecu would just make your engine run like crap. Your engine has its ecu tuned to work for the power output of your car... if you switch your ecu with a computer from a 90hp engine to your 120hp engine, then it will be running hella lean, since the 90hp engine requires less fuel. It will most likely just make your car sputter/run like donkey shit.

That's some awful gas mileage there mcsierra, you should give it a good ol' tune up.
Unless it has a swap.

There's a simple solution for this question, invest in this :

Also downgrading to the taller geared HF transmission would help, but then you give up performance. |
