I will not unleash on you, but I will say the adjustable cam gear is a great tool no matter what cam you are running.  You could justify ordering one just for the sake of seeing what happens and it still wouldn't be a waste of money even if you ended up ditching that cam.  In my recent experiences adjusting the cam timing made large differences in the way my 22R ran.


You can "unleash" on me anytime.... I have big shoulders... I can take it.  :smooch:

You already know, I have mentioned it, and it's well documented, the modifications you do to a carb'd engine respond VERY differently than the modifications to the EFI 22.  :thumbs:

I don't think changing (advancing or retarding) the cam timing (depending on who's profile), will be as noticeable in an effort to get power gain or better throttle response, or fuel mileage, as it will on a carb'd engine.  I think the 22RE ECU and sensors will try to keep the mixture, ignition timing, etc, within a programmed range... most likely designed to meet the emissions regulations of the 80's.  I could be wrong, but so far that's my experience and seems to be consistent with the 1000's of post I've read on the subject over the past 15 years or so, coupled with the conversations I have had with some the most respected Toyota engine builders, camshaft manufacturers, and automotive racing experts on the planet.  :smokin:

Once I get the engine running right, I do plan to do more "tweaking and testing".... an adjustable cam gear would be a nice play thing.  :D

Before I start experiment tweaking, I would like to get this engine broken in and running like I think it should.  :driving:

Gnarls. :spin:
