LS/VTEC is a waste of money if your not gonna change out the tranny. Without a B16/GSR/TYPER tranny you'll be running almost like an LS, but you'll just have VTEC. I would personally go LS/VTEC+GSR TRANNY for everday driving, but like everyone else said its really just personal perference. I say stay LS untill you can fully built your motor because theres no sense in doing VTEC+B16/GSR/TYPER tranny. You'll still be slow.
