Default What mods are required to put a Civic engine and transmission in my Prelude?

I know it may sound stupid but I love the look of my 1992 Honda Prelude S. I'm just looking for better fuel mileage. Stock for stock, the 1.6L non Vtec in the 96 Civic get's approximately 30mpg city, but the F22A in my Prelude is about 21. I thought about performance mods to the motor for mpg instead of the swap, but from what I've read, they don't really work. I do not care about hp what-so-ever; just fuel mileage. I also hear the gearing of the transmission in my Prelude would probably decrease mpg also. Does anybody have any tips on the best way for 30 mpg? Keep in mind, I don't care about the power. I'll save that for my Camaro.

Remember the Civic is a lighter car and it has thinner tires in width making it more fuel efficient.































Switching out the engine will cost you $3000. To pay that back in the money you save on gas will probably take over 10 years.

You will get worse mpg if you swap a smaller civic engine. The d15 (fuel saver) civic motor has about 96 crank hp. The engine will struggle to move the heavy prelude and thus you will have to use "more" fuel when driving. This is all together a bad idea. A good tune up (plugs, fuel filter, air filter, oil change(synthetic only), wires, dist cap, dist rotor) will net you more power and more efficiency. Also replace your gear fluid with synthetic. This will make your transmission work more smoothly and easily giving you better mpg. You can get a cold air intake and some exhaust modifications. these modifications make your motor breathe better and run more efficiently. this helps mpg as well as power which is used to move your car. All this equates to overall better mpg. Just because its a "power" modification doesnt mean it wont help your mpg. Another enemy of mpg is weight. this part is up to you. remove what you want from your car and the mpg will go up. Thats all i can say about weight removal.

You have the most fuel efficient prelude as is. There are no parts made to swap in a Civic engine, so all will have to be custom made which will cost more than any money you would potentially save on fuel.















If you want Civic mileage get a Civic.
