Dimensions are in./mm

Note that the 43 mm outer diameter can be made a little larger, but not too much because of dishing of the timing gear. The 10 mm inner radius is the dimension of the cam, so that dimension should not be made any smaller.

Also, the slot leading up to the dowel hole is present in the timing gears, but really all you need is a 6 mm dia hole at a radial position of 17 mm from center.

Special thanks to Bags for providing me with VQ30 cams so I could figure out the spacer thickness.

 

Wow NICE! Take THAT JWT!!!!!!!

 

"Very industrious for a Cossack..."

That's a sweet rendering you have there. Plan to make any on your own?

 

Nice work Stephen...

 

why isnt the picture working??

 

i cant see the pic in the thread but i can down it from the site
thx stephen max

 

great work! Pics down for me also.

 

so now the question becomes: who will mass produce them?

 

I don't think there are enough 3.5 swaps going on at the moment to justify mass-production.

 

I have on going on

 

If you plan to use stock 3.5 cams whether it be in a 3.0 or 3.5 swap, you would be better off getting Tilley's new spacers, but I think these would work better for aftermarket cams which have a different base timing. That way u can drill the cam holes accordingly.

 

Has anyone ordered them from him or am I the first? This is going to be the start of the 5th week since I placed my order and I haven't heard from him on two weeks. Just want to know if this is standard wait time. I know the first two weeks is just receiving the spacers from JWT but I spoke to him after he received the spacers. Hope he gets them out to me soon.

 

I just ordered 2 sets from him. He said 2 weeks wait time. I need these for my 2 swaps this month.

 

When did you speak to him?

 

I spoke to him online earlier today.

 

wow i need to order a set or if someone can make me a set

 

so why do people say the cam needs redrilling??when the pic above doesnt have anything to do with redrilling??

 

If anyone needs a set of spacers, I can make them. I have made several sets already, the set that went into Dubbya's engine, and a set that went into Meximax's engine, as well as others. I haven't advertised before because they look a little rough, but they are the correct thickness and they work just fine.

$75 a set.

 

Interesting. I will wait to see waht happens with my set. I have left numerous messages and have not received a returned phone call. I will see if he sends out this week.

Mike

 

$75 for all 4? (sent you a PM before I found this post and had more questions)

 

You only need 2 spacers, one for each intake cam IIRC.

The pic is down for me too.
But from the first post I have all the dimensions I need but the thickness.
What would that be?
Thanks.

 

You need one for each cam.

 

Yep. I just did some reading and came back to edit but you beat me to it.

 

the pic is not working

 

argh, does anyone have this picture on hand still? or even better, that is the actual thickness of the spacer?

 

Mine looked like this before I installed them:

Here ya go!


I think thats correct. I had made this about 2-3 yrs ago and IIRC, Stephen Max said it was correct.

 

3 mm is the correct thickness.

 

sweet thanks guys!

 

Hey grey99max, do you happend to have a pics of the spacer installed ?

AA

 

sorry crappy cell pics

 

That pics is fine, that will help me with final assembly.

Thanks a bunch.

AA

 

??? That intake cam spacer looks reversed. The long side should be sticking outward in order to index the secondary and primary timing gears. The short bolt fits into the dowel hole in the cam.

 

Hey Stephen, finally those spacers will get in the engine shortly. Thanks for the precision, I take good note of it.

AA

 

What angle is everyone running their exhaust cams? It seems to be a consensus that 180+2 cam angle is good for the intake side of S1 knockoffs, do people just use the same spacers for the exhaust side?

 

the dowel pin on the exhaust side isnt altered so it retains its stock spec

 

thanks a bunch guys! 915Max I think what you are trying to depict is that the two dowel pin holes are 178 degrees to each other, centered at the middle:

 

Hi guys, from pic posted above it is not clear in which way should bolt be moved, and I think this makes difference.

Can you tell me which one is right: 1 or 2? (short -green- bolt goes into cam, longer - red - into timing gear)



spacer are going into vq30de, Maxima QX 1999, to hold vq35 cams:

VQ35DE (2)
Model Years: 2002-2005 (Maxima, and a slew of others)
CVTC: Intake

Intake__Lift: 9.5mm
Exhaust_Lift: 9.5mm

Intake__Duration: 238ş
Exhaust_Duration: 240ş

Intake_Opens: 6ş ATDC
Intake_Closes: 64ş ABDC

Exhaust_Opens: 52ş BBDC
Exhaust_Closes: 8ş ATDC

 

Stephen, will these spacers make any VQ35 cams a simle "bolt on" for 3.0?
Since VQ35 is variable cam timing, where do these put the timing relative to 3.0?

 

The VQ35 cams have a 6 mm dowel hole that is 180 degrees out of phase with the VQ30 timing gear slots. It is unused in the VQ35 engine. There is a small hole (1 or 2 mm dia) in the cam in the position corresponding to where the dowel hole in the VQ30 cam is. This small hole is used to position the VQ35 VVT timing gear. The cam adapters provide a short 6 mm dowel that mates with the VQ35 cam's 6mm dowel hole (the green dowel in the illustration), and a large dowel in the opposite directon that mates with the VQ30 main timing gear and the intake secondary timing gear slots (the red dowel).

With the VQ35 cam positioned so that the small hole is aligned with the VQ30 main (i.e. large) timing gear slot, the intake valves open at 6 deg ATDC. The exhaust valves close at 8 deg ATDC, giving a valve overlap of 2 degrees. If you want the same amount of valve overlap as the VQ30DE cams (6 degrees), then you need to advance the intake timing by 4 crank degrees. This corresponds to rotating the cam 2 degrees in a clockwise direction. Configuration 1 gives the correct orientation of the small dowel and the large dowel. Configuration 2 retards intake cam timing by 4 crank degrees.
