I was actually just talking about copying Harry's setup of an Si head on the DX block, with a coupla DCOE's.

But...

In theory you could get VTEC to work on a carbed car. The easy part is hooking up an RPM-activated switch to trigger the VTEC solenoid. You'd also have to wire up a new ignition setup but that's relatively easily accomplished.

The only real hard part is figuring out how the hell to jet the carbs.
