When you say VQ30 cams, you're referring to JWT VQ30 cams and NOT stock VQ30 cams, correct?

 

^^ I plan on using stock VQ30 cams. Wouldn't that be the easiest way to reuse the 3.0 timing equipment? (no drilling etc..) I was told that this is the plan Tilley is doing for one of his customers.

 

I guess.........

 

Coool... I guess if Tilleys doing it, it should be okay.

 

If it's a turbo car that's not a big deal, but for a NA car, I'd go through the hassle of sending Tilley your intake cams for drilling and buying his soon to be available JWT clone spacers.

 

any idea how much it would cost for tilley to drill the holes and spacers?

 

Spacers *WERE* $40 + shipping directly from JWT...not sure what Tilley is/will charge.

 

spacers were 40 for a set of 2 only..... so for the whole set its like 80 or something..... and tilley says his will be cheaper

 

Hmmm, if it isnt too expensive for him to drill the (VQ35 cams??), then i'll go that route.. But aren't the spacers only needed for the intake cam gears because the exhaust cam gears are thicker?

 

NO. You will need them for all 4 sprockets. The spacers go between the sprockets and the cams. If you try and visualize that, you'll see why all 4 need them.

 

Gotcha. 123465

 

japmaxSE said he only paid $40+shipping.

 

That's before they realized what was going on

 

A set of 4 spacers are exactly $40.00 for shipping they only allow FedEx only it will come out to $58.00 or $60.00 exactly.

 

Exactly, so Emma or Tilley saying they are $80+ isn't correct, since JWT just raped Tilley on "the last set".

 

I'd be more than willing to buy a set of Tilley's spacers, once he produces them.

 

at the time that japmax bought them, apparently they werent dealer only products, but they switched that i guess and when they made it a dealer/business only product, they bumped the price.... (i dunno thats what i was told)

 

Any word on Tilley making the spacers? How much is he charging? I need a set!

 

Word on the spacers?

 

Well all machine shops want alot too make them. But if anyone needs em i can sell em.

 

How much??????

$80 SHIPPED for all 4. $50 to redrill intake cams shipped

 

Any word on my cams and spacers??

 

They are on there way too you, sent yesterday.

 

What are you doing relative to cam timing?

Using the EM section specifications of the VQ30 FSM as an example the intake opens at 3deg btdc and the exhaust closes at 3deg atdc, an over lap of 6deg, that seems pretty good and would be a target. If you look over the VQ35 FSM the exhaust is fixed at 8deg atdc, but check the intake... it shows 6deg btdc so an overlap of 14 deg, more than double the VQ30 overlap, not good for boosted applications. BUT the total duration of the VQ35 intake cam (dimension b) shows as 238deg, But add up the other dimensions (c)6btdc + 180 + (d)64 abdc = 250deg of duration? so is the 250deg total timing with the vtc control? if so thats only +/-12deg off the (b) dimension. Now if you check the EC section of the VQ35 FSM and look at the IVT section the control indicated zero to -5deg at idle and zero to +30deg after 2000rpm. That dosent make sense to me, i must be missing somthing. This is important to know so the VQ35 cams can be timed properly in a VQ30. If the cam advance is wrong it can hurt power, excessive overlap is BAD for a boosted car.

What ya know?

 

Yeah, the VQ35 FSM seems to have an error, but those numbers don't include VTC operation. VTC operation is shown here:



A bit more overlap would hurt spoolup somewhat, but the increased duration and lift would really help top end. Also, with a SC car a bit of boost being lost during overlap is a concern, however with a turbo you can just compensate by running a bit more boost.

 

Just to help others without a FSM visualize what you're asking, here are the VQ30 FSM cam specs:



Here are the VQ35 FSM cam specs:



e = EVC = 8-degrees ATDC
f = EVO = 52-degrees BBDC

 

Thanks Tilley!

Icey: Good info. I get lost when it comes to timing, I just hope I put everything back together correctly..

 

Thanks Ice... I suppose a degree wheel could nail down where to drill the new pin hole in the propper location so the overlap is not an issue.

 

That's what I was thinking/wondering, ie adjusting the intake cam advance angle to work with the stock exhaust cam.

I have a SAE tech doc on the VQ35s that includes some kind of chart on the optimal RPM for IVC to produce peak torque in the low, then mid, and finally top-end. However, it is pretty hard to read and I can't make much of it anyways.

Isn't there a program/tool like Cam Doctor or something that some shops use to run a cam through and it measures all the cam specs?

 

What shipping service did you use? They aren't here yet


EDIT:

 

what about the spacers from the original vq30 cam, maybe you can reuse that. any one have pics of those,

 

There is no spacer on the VQ30 cams.

 

VQ30 cam on the left, VQ35 cam on the right:

 

I think I got mine today. It's either that or the tach.

 

Well...I only got two spacers?

I need four per this thread, correct?

 

Yeah you need 4.

Haven't gotten my cams yet. Damn...

 

You do need 4, it took forever to have my cams back to me, because JWT only sent Tilley 2 of them also.

 

How stupid is that on JWTs part?

They don't know you need 4?
