It would be interesting to see if it could be done with the F20c and F22c engines. Would the currently available standalone EMS's even be capable of running this on a F20c or F22c engine?
For those that dont know much about it, here is a basic rundown.
iVTEC(intelligent-VTEC)[3] introduced continuously variable camshaft phasing on the intake cam of DOHC VTEC engines. The technology first appeared on Honda's K-series four cylinder engine family in 2001 (2002 in the U.S.). In the United States, Honda first debuted the technology on the 2003 Honda Civic Si EP3 with the economy version.
Valve lift and duration are still limited to distinct low- and high-RPM profiles, but the intake camshaft is now capable of advancing between 25 and 50 degrees (depending upon engine configuration) during operation. Phase changes are implemented by a computer controlled, oil driven adjustable cam gear. Phasing is determined by a combination of engine load and rpm, ranging from fully retarded at idle to somewhat advanced at full throttle and low rpm. The effect is further optimization of torque output, especially at low and midrange RPM.

still 2200......i know it's a great adoption of technology onto our motor and i'm glad people are doing this, but 2200 is a ton of $$ for this. i think if someone is doing this for a pure power increase, they could build a spare block for not that much more, use a stock head, and make 8xxwhp

The results he got on the BC time attack car where very impressive. Added 90 peak hp without adding more boost or increasing displacement. If you dropped $5000 on a turbo setup, this can make it come in alot sooner. I think this is an amazing tuning option to help make our engines even better all around. It appears to really help on low and mid range the most.
