Is anybody making adjustable cam gears for the 350z?

 

dual over head cammed motors i dont think u can do that....free bump for more info...

 

I have heard that Nismo just stopped manufacturing their VTC pulleys...

The only other option that I know of is the HKS Valcon which i believe only works on Japanese model cars...

VQ35's have continuously variable intake cam timing. Meaning it's always changing depending on RPM and load for optimal performance. If you're speaking in terms of the exhaust cams, no such thing exists.

Ehhmmm, no. Hondas VTEC motors, for instance, have dual overhead cams and they make adjustable cam gears for them. They're not made for VQ's because they have a closed, "wet" timing cover.

 

Two completely different types of products. As for the latter, there's V-Manage available for that.


That stinks about the Nismo VTC phasers though. I think I remember reading somewhere that the 07+ altima VTC phasers have a wider sweep than the previous VQ's. If not, there's always the possibility of opening up a stock phaser and trying to grind away at the stops to give them a wider sweep.

 

Please enlighten me on how these are two completely different products?

Here is another page for reference:

+1 He's right.

 

the only adjustable sprockets were the NISMO ones

Even still, having the pieces themselves give you zero benefit - they are only designed for use on high duration cams (ie not stock and not the typical JWT, or US Spec NISMO ones most people fit) with steep ramp rates - think JUN, Tomei, Esprit, type cams. And then, you need an ecu that can actually control them. At the present time, there are very few ecu's that can do this (Haltech, Pectel, Motec, Hydra are all I am aware of)

Of course you can adjust cam timing on dual overhead cam motors......Subaru, Mitsubishi, etc etc

The Valcon is a plug and play controller for use with stock cam sprockets - lets you manually dial in cam timing. Problem is its not officially offered in the US, and not the easiest thing in the world to get interpreted instructions for.

 

I have Tomei cams and will be using MoTeC, so now just looking for adjustable cam gears.

 

NISMO are the only ones offered - I can check if Japan has more tomorrow

 

I would really appreciate that.

 

Z1,

do you have any info, specs, head size, stem length, etc on the NISMO titanium valve set and the nismo valve springs (seat pressure at ?? installed height, max lift, coil bind, spring rate,etc) on your website.

 

the ti valves are only meant for the NISMO heads

 

after using google to translate the hks page it looks like it is only offerd for the VVT-i systems that toyota uses.

 

there are cams and a controller for the VQ as well, but its a Japan market piece only

 

Here is the page that mentions the VQ35DE:

Ah ok. How much is the japanese unit? Might be worth it to play with the wireing and see if it will work.

 

around $2k (includes cams that are 264 degrees with 10.7 and 10.2mm lift (in/ex)

hardly worth the money IMHO

 

Oh you cant get the controller on its own?

 

From talking to Unorthodox racing I got word that they had considered making adjustable sprockets for the VQ but the cost of making them was too high to be feasable.
