The 86-87 LX-I has 110 HP and the 88-89 has 120 HP the carburated ones 86-89 have 98 HP. I have a 88 LX-I and there is not alot of aftermarket support for the 3rd gen Accord. I have a K&N drop in filter and a custom catback exhaust and thats about it good luck with it and post some pics of it. Check out www.3geez.com like wedley2 said, that site will be more helpful to you for the 3rd gen.
