How about you give me a $1,000, I'll kick you in the face and we'll call it even. You can't add v-tac...

I doubt you can do it... you would have to have a balanced high tq motor that would have to hold up against the crank tq and overcome it to be able to rotate the gear... the crank would have more leverage to begin with though because it uses the cam gear which would be larger then anything you could fit onto the cam gear.
Maybe a hydraulic ram and some kind of spiral groove in the shaft to wedge and rotate the gear.
but then the shaft whould have to not rotate inside the hydraulic cylinder.
problem is how would you connect the ram(s) to the gear and have hoses that could spin with the gear as well?
the gear would have to have some kind of free spinning joint to feed oil through the shaft and up into the gear where the hydraulic ram could use it.
or maybe turn the spokes of the gear into hydraulic rams themselve with internal cylinders.
I dunno though since you'll be fighting centrifugal forces + the power of the cam /crank trying to spin the cam against the valves.

you sir, just gave me an idea!
I was thinking, if you want to advance/retard cam timing on the fly...mount your tensioner on a sliding plate with another idler against the front side of the timing belt. If you were to slide the plate to the rear of the engine, it would "kink" the timing belt on the front of the engine and allow it to straighten on the rear, pulling the cam gear forward in relation to the crank gear, effectively advancing the timing whilst maintaining belt tension. A diagram would probably help, but if you understand what i'm saying, you could do it in conjunction with an electric solenoid or maybe hydraulically. Trouble is, it will advance/retard your ignition as well.

A rotary manifold you are talking about. Ever seen a hydraulic excavator? they can spin the house 360 degrees on the track frame, and the tracks are hydraulically powered. The engine and pump is in the house.

no, not worth it. would require the fabrication of a new cam design, probably relocation of the valves and possibly a complete redesign of the cylinder head. and of course the little things, vtec solenoid and what not, computer system. but, if you would want to swap an engine in with a vtec head already on it, then yeah that'd be worth while. maybe like a B or F series, or if money would allow a K series.
Keep it HONDA. Or at least Asian.™

my point was along the lines of variable valve timing as opposed to the actual V-TEC lobe switching system.

not to be a turd, but its one word all together "VTEC" when written out. just something that is a pet peave of mine. dunno why its overlooked. just for future reference. lol.

Just keep one of these in your car. Besides, its mAd tYtE JDM y0

Anyways he was talking about Advance and retard, not different lobe profiles.

...apparently a little more retard and a little less advance. Thats variable valve timing, not "V-TECHK"
