So when I bought this car, they told me it had a GSR motor with a B16 head. I took it to a friend of mine and he told me it was an LS/VTEC because it had oil lines coming out of it that a GSR doesn't use. Well the block number have been ground of (prolly hot) but the block still had a VIN on it. I ran the number through Carfax and it came back as a 1997 Acura Integra RS motor. Does that mean it is an LS/VTEC or what?
