maybe just upgrade to 88 or 89 tail lights... they go all the way to the liscence plate... Im not too sure about the fitment, but I think the 88-89 tails look better without the black piece by the plate.

As far as I know, there are no aftermarket tail lights for 3rd generation accords... so thats most likely why your search has turned up nothing.

From what I know, a B16 or B18 can be mounted in that car, with the proper kit... maybe a ZC or LS motor also... all of them have 10times the potential of the motor in your car. What model and body style is it? If its an LX or DX a swap will be much harder, as a swapped motor would need fuel injection, which uses a whole different fuel system/tank than the non-FI motors.

There are plenty of cat-back exhausts, lowering springs, wheels, body kits (please keep them SIMPLE!) and wings available...
