I have a 89 honda accord lx-i and I think the compression ratio is 9:1. How much psi could I push if I port and polished my engine. Also what kind of engine would be easy to swap into my car.

well, if you want some good info on 3rd gen accords, goto 3geez (www.3geez.com)

there aren't too many swaps for that car, my buddy and i put a 2nd get prelude si engine ( a20a5 / bt ) in his 87 accord hatch, but that's basically the same engine you have ( a20a3 if it's fuel injected, a20a1 if it's carbed)

i guess it might be possible to bolt an F22 engine in ( F23A4Racer750IL http://www.automotiveforums.com/t321670.html)

i know on preludepower.com there are a few second gen preludes (A20 engines) with b16 engine swaps, and one or two with b18a1 integra engines

proly the best and easiest would be a b-series from what ive seen. forgot where i saw it, but there was a 89 accord with a 0bd1 b18c swapped in. anything in the F and H series will be a little harder to fit in, somewhat like putting one in an integra or a civic.

at this point, h and f series swaps are not realistically possible, they'd require totally custom mounts and custom axles, and some other things

i guess a D series engine could be swapped in, making note of the proper OBD wiring, so an older crx/civic engine should plug right in
the A20A3 / A20A5 engines have around 110 hp, and the D series engines can put out 125-7 or so from the factory, so it'd be a decent swap to get a little more power and gain a few mpg by decreasing engine size from a 2.0 (1955cc) to a 1.6 L.

not sure where you get the mounts, i guess place racing (of placeracing.com) has gone out of business, so i'm not sure if any mounts for this type of swap are even available
