Can someone please provide me with stock specs on 3.5 cams Deg? Lift? etc.

For 02' 03' 04' and the 350Z "if there not the same".

VQ35s are internally the same except the first gen Pathfinder(240hp) and now AE 350Z.

Anyways, with the CVTC off, the FSM says:

Forgot to add, lift is 9.2mm.

Thanks for the injector ? So it can be done but I don't have 00',01' LIM

SR20 Says The 3.5 injectors actually flow less than the 3.0 injectors at the same pressure.

Sorry but I'm having trouble reading this.

I'm trying to compare them to Jimwolf cams 4th gen S1 VQ30DE BILLET CAM SET 256 DEG .415" GROSS LIFT.

So the AE 350Z is not the same but the other 350 models are.

Yes, injectors on the VQ35 Maxima flow 270cc, but on the VQ30 Maxima/350Z they flow 290cc.

JWT have 10.541mm lift vs. VQ35 9.2mm. JWT have 256 duration vs. VQ35 238-240 maybe?

Anyways, if you're using VQ35 cams, get Tomei not JWT.

Rumor says Nismo rod bolt to support higher RPM and I think bigger cam, but I could be wrong.

I measured the stock cams at 9.5mm lift. I wonder where this 9.2mm figure keeps coming from?

And you don't have to waste your money on that worthless JWT crap. Just buy Tomei or Nismo 350Z cams and use them. They can easily be made to work.

You forgot to mention this is at 3.0 Bar. The A33B uses a fuel pressure of 3.5 Bar which effectively makes the injectors 315cc. This is what the world can't seem to understand.

Old azz published SAE document...so probably not 100% current anymore, just what I refer too since I don't remember off the top of my head.

True.....

VQ30 290cc@3bar(2000-2001 Maxima)
VQ35 290cc@3bar(2003 350Z not sure on 2004.5+)
VQ35 270cc@3bar(2K2+ VQ35 Maxima/Altima)

So I should stick with VQ30 INJ and bump the pressure up when needed for more fuel with the aid of a A-FPR.

Correct me if I'm wrong, can you use a diffrent FPR off another car.

Yes, it wouldn't do you any good to switch to stock VQ35 injectors unless 2004.5+ are bigger then 290cc@3bar. There are aftermarket injectors that are bigger though.

You can raise fuel pressure, but depends on what setup you're planning.

true
For now stock is good but I want to play with it a little raise the bar.
My setup is similar to Tilleys.

Which one? LOL! VQ35 shortblock w/VQ30 heads, right?

Walbro will bump up the fuel pressure a bit, so you'll have plenty of fuel NA.

Any updates?

Looks like you tried the VQ35 cams in your VQ30 heads, but too short?

Have you looked into the JWT "sprocket adapters" for the 2000-2001 VQ35 Pathfinder as a possible solution?
