Toda has em... but they're not cheap.
Has anyone heard of somewhere that has an adjustable vvt gear for silertop 20v's? If not, I wonder how feasable it would be to engineer one...

the toda ones are VVT canceling. I don't beleive its practically possible to make aftermarket VVT gears because of how increadibly complex the internals of one of these are. I would be neat if someone did make them though because then a set could be made with a reduced angle of movement which would be compatable with longer duration cams-shafts than what stock would allow

<div class='quotetop'>QUOTE (Sam_Q @ Jun 11 2008, 06:50 AM) </div>Do you have a spare one we could pull apart and look at Sam? Nothing is impossible. How much movement is preferable? How many degress of movement does the standard item have?
If you want a locked adjustable cam gear for the inlet, then Toda is the best. Also some europeanan companys make them (look on AEU86), also OBX i think do them, look on ebay USA. These sorts of cam gears fit inlet of stock 20v and aftermarket 20v cams such as Toda. VVT is gone once you use the cam gear.
If you have a TRD camshaft for 20v, then I think you can use 16v cam gears. Or similar anyway.
To keep the VVT cam gear with reduced movement, have a look on the road and track website. They do list this as a modifyed part.
no I don't have a spare, and I agree it isnt impossible. I have been warned that they are so complex that you should never try and take them apart, true or not I don't know. i would love to see inside one.

I have a spare. I will get to pulling this apart soon if you like.
Does anyone know how much movement they have? And how much movement you want? I saw somewhere the AE111 has less movement.
please take some good quality pics if you can, so I am guessing the one your going to pull apart already has the "click of death"?

I have an adjustable VVT camgear on my 20v. It is really quite a simple solution that uses adjustable stops to change the start and end points of where the teeth sit in relation to the centre of the gear. The stops are external to the gear so there is no dissasembly required - just some quality welding, drilling and tapping.
I have no idea what your talking about any chance of a picture or diagram?
