Ok, something i've been tossing around in my head.
I've been wondering about modifying a B16 cylinder head so that only the exhaust cam lobes are actuated when vtec activates. I know that the intake duration is more of a problem than the exhaust. True, you can compensate the overlap with cam gears, but when your not under boost you would see a lack of power.
I wonder if this is even worth trying, or would it be a wast of time?

 

How do you plan to do this? There is no real access to the oil ports that run only to the intake side to block them... and if you remove the intake side vtec pins and rocker arms nothing will hold the non-vtec arms and you'll lose vtec oil presure...

Not to say it cannot be done though..

It could be done by drilling a hole directly into the main oil passage for the intake side, and plugging it up. I dont have a vtec head to chop apart to experiment, but it seems doable. The exhaust train would still have oil pressure, just nothing (or less) going to the intake side. Also, i'm sure modifying the rocker arms would be easy enough. You could probably just remove the pins and plug up the passages.
