LS/VTEC is a waste. Unless you spend big money to do it right and complete but in that case, you might as well just get a GSR swap for the reliability.
The smart thing to do is get a low mile B18B and pair it with a B16 or GSR trans. With a turbo, some turbo app cams, cam gears, and a tune you get some actual power and you still have room to expand. Who cares about VTEC when you have boost?
With LS/VTEC you'll have problems and never get the car running / idling right. You'll never find a good tuner that can / will work on a frankenstein Honda. Just a lot of fools pretending to know how to tune. You end up what amounts to a GSR with more top end and higher compression. With a bottom end that doesn't like revs. Where do you go from there? Tear it down again and build N/A?
