I posted the exact same vids in the vtec/mivec discussion in the car mods forum thread.
The SR16 is a killer engine. They just chopped the top off the SR20 block until they got 1.6L. That means bigger pistons and less piston travel. Bigger bore, smaller stroke = very rev happy engine.
When i first saw that video i was blown away. Too bad they didn't make that many SR16 Neo VVL N1 engines.
