Hi,

There was no GS model in 94, the term used for the GS back then would be the SE- which has a B18B (143hp). The GS-R only comes in a 5-speed and has a B18C (170hp). Just because a car has GS-R rims and a moonroof doesn't make it a GS-R. Ask the owner what trim line the car is, and verify it with a VIN lookup on carfax.com. As far as buying a new motor and dropping it into a high mile car that's not a bad idea if you can get a steal on the chasis (and its in good condition). One other thing is I would stay away from someone else's project. Buy a car that's bone stock, it's less likely to be beat on. Always get the car inspected by a mechanic!
