3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I heard that you can slip the teeth of the cam gear on the 3vzfe so that the intake valve can open sooner, before the exhaust valve closes. Well I been searching around with no luck.
on the 3vzfe, does a single cam gear time both cams on the one side? if you had dual timing gears on each side, then MAYBE you can adjust the valves opening and closing.

Actually I'm not sure of your question. But I'll try my best to answer, I believe it's dual timing since both of the cam gears on each sice has little indentations (marks for lining up both gears when putting it back together).
If I have dual timing gears then, how would I adjust it?
why would you open the intake valve while the exhaust valve is still open?
It's called overlap, and it's employed to let the engine breathe easier at higher speeds. Problem is that a lot of overlap near idle the engine runs like crap. If you've ever pulled up at a light next to an old muscle car that's all done up, it sounds like garbage while it's idling, but once you get it going it'll scream. Variable valve timing will give you the best of both worlds by having normal timing at low RPM, and then advancing the intake valves at higher speeds for better breathing. Sounds like the op wants to advance the intake cam to get that effect. Who knows why. Maybe he never lets the engine dip below 2500.

it makes sense in muscle cars ... but i dont forsee any advantages on a 3VZ-FE ... like you said, its probably going to hurt him more than help him at low rpms
also - youre crazy if you think muscle cars like that sound bad @ idle ... i think they sound like beasts
