just curious with the K20 head.. does it provide better flow?

i remember a guy who bought stage 2 cams for his Accord with K24.. not really sure if how he went with it, but as far as I know he bought injectors, vernier cam gears and hondata ecu...

There's VTEC, and then there's VTEC

Honda has used two very different VTEC systems on K-series engines. In spite of the engine's differences, both happen to be called i-VTEC. The first system, found on the K20A2 (RSX Type-S) and K24A2 (TSX) has three cam lobes for each pair of valves. At low rpm, each valve follows its own mild cam lobe. At high rpm, they both start following the third lobe, which has higher lift and more duration for better high-speed cylinder filling. This is the VTEC you're used to. The second system, found on the K24 (Element, CR-V, Accord) and the K20A3 (base RSX and Civic Si), is designed to minimize emissions and maximize driveability and gas mileage. In this system, there are two cam lobes, a normal one and a puny little atrophied one, for each pair of intake valves (nothing happens on the exhaust side). At light load and low rpm, each lobe opens one valve, so most of the intake air goes through the valve that's opened more. This creates a swirl in the combustion chamber that happens to be great for combustion efficiency. Floor it, though, and one valve won't be enough, so both valves follow the bigger lobe. Notice there's no screaming high-rpm race lobe here.

In other words you can have unicorn powered VTEC or you can have sissy powered VTEC

(much better flow)
