whats wrong with VTEC?, its almost exactly the same in operation as VVL except both cams switch at the same time.
yes it will fit.....just with a bit of custom work, all new engine mounts etc not to mention the engine sits the other way round and then theres the issues of getting axles that will fit the integra hubs
but yea if ya want to do it go for it, although there seems little point removing an engine that is already very good (assuming a B18C).
