For a '92 civic hatch, will a '93 Integra GS engine and tranny bolt right in?

It's a B18B1, and I see that the 94-97 LS (B18B1) bolts right in to the stock mounts. I just got a whole '93 integra that runs, and I'd love to have an LS motor in my hatch. I've read hybridgarage and hybrid2.honda-perf.org. None of the info I can find indicates that this drivetrain will work, but it's still a B18B1.

Does anyone know otherwise?
