gen 2 integra d series swap (high mpg)
i was curious about swapping a d series engine into a 90 integra so it would get higher mpg. i know i am gonna get flamed on for this but i really love the second gen integra and i also love the idea of the civic vx getting like 50 mpg. i know that it will need to be wired for vtec and the five wire o2 sensor but has anybody got any more info on this. any POSITIVE input on this would be greatly appreciated.
thank you jake

wow..this is probably the first D to B swap thread I've come across in my lifetime :P
I dont think it would be any different from swapping an LS into a Civic. just...backwards. Same process though. You'd have to get D-series engine mounts, you'd have to get the tranny, ECU, shift linkages, axles, etc.
Basically everything.
I'm not entirely sure why you'd want to do this though. the gas mileage aint that much better. (coming from a 96 civic driver) My D16Y8 is decent on gas, yet..I see no reason to swap out a B18 for it.
For what it would cost you to swap to a D you could probably get your B tuned for gas mileage. you could probably hit low to mid 40 MPG's.
You could probably just check your motor now and give it an overhaul if it needs it and then get it tuned and get good MPG's.
Here's what I'd do atleast. I'd first run a compression test, then a leakdown test. see if my engine is healthy. Then if it was on the original stock head, manifolds and oil pan gaskets. I'd replace those with fresh OEM ones after making sure to take a solvent to the block under the gaskets to make sure it is free of all left over crap. Then while I had the engine with its major parts taken off (head, oil pan, etc) I'd pull out my pistons, get new bearings for them, and new journals for the crank. Once done with the bottom end, bust out the feeler gauges and check the clearances on the head make sure they were within tolerable limits.
While the pistons were out of the bottom end. Maybe get it hot tanked (if you have that available near you) I'd also check the cross hatching in the cylinders. Honda's pretty good and keeping the cross hatching on the cylinder walls.
you probably get the idea by now...check all your shit and clean all your shit. make your motor as clean running as you possibly can. regardless, after all that, reassemble it with the fresh gaskets. maybe get some ARP bolts to hold it together better helping compression and lowering the chance of leaks. then get it tuned on NepTune, or HonData or whatever is available to you. (NOT AN SAFC or anything like it) then you should get as good of gas mileage as any D-swap.
My Y8 when it was stock got about 34-36MPG
