I had the honor on meeting the guy who invented the LS/Vtec setup (Omniman) a few years back when he was in town.
Lots of knowledge and learn alot about the K-motors before the RSX even came to America.
Didn't bother reading the link since I help someone build a LS/Vtec back in '03, to date, still runs faster than my build C5.
Crazy yO!
