A bit O/T but one of the ae86 club videos features Sakurai's 20V street car. It seemed to be fully optimized in regards to everything I've been learning that can be good for 20v: 288 exhaust duration vs 272 intake (20V head is choked up on the exhaust side), 10.5mm lift (his own special cams) since the 20V increases flow up till about 11mm or so, and ae101 throttle on a blacktop engine! The black top throttles are actually too big for 4a bottom end for street use, so this likely increased his mid-range w/o effecting up to much at all. So boss. Unfortunately the car had some kind of issue and I never really got to see how well it performed...
