VTEC isnt really all economy. Its more of dont add just big cams to lose some power down low. Take the lobes for VTEC and use that size for all RPM or set your VTEC to engage at like 2k lol I bet that shit runs like shit unless its built and has a good tune. I think the best part of VTEC is the sound. Damn I love that ITR crossover. baaaaaaaBAAAAAAAAAAAAAAAAAA HOLY SHIT WTF JUST HAPPENED!?! Time warp nigga! like said above Honda's light speed but seriously when VTEC hits in a ITR you cant miss it. Shits loud! Probably the same for a B16 IDK.
