Except for the glaring hood clearance problems, what other conflicts with the mating surface of the Path IM to the 4th gen cylinder heads, using the Pathy Lower manifold.
Has anyone actually tested it to see if it will fit?

 

The intake ports of the Pathfinder VQ35 are identical to the VQ30DE, so you can bolt the Pathfinder IM right on.

 

hmm, now we are talking about the true dual runner type right? Might just give that a try someday. Thanks

 

Interesting.......

 

Yes....I've got $50 to anybody that pulls it off.

 

I think you just pissed in the punchbowl...

 

No that's a true dual runner set-up, even on the Maxima advertisment bookelts, they show a dual stage all shiny'd up in chrome, and with many details, and we all know it's really not in the Max, false ads anyone ...

 

Pathy is TRUE dual runner setup. It has a set of long and short runner. Or atleast that is what I am told.

 

I've seen that drawing all over the place sucks we didn't get it... jsut wish the max had the dual runner, also the sentra SE-R has the same basic design of the true duals in that drawing too. That concept and drawing is on a few of the technical VQ35 papers.

 

Why's that?

 

what year pathfinder is that picture from?

i believe the new vq40 equipped ones have a different manifold, right?

 

2001(late) to current or at least 2004 all have the same IIRC.

 

Hey...that would be a good excuse for a CF ram-air scoop Larry.

i have a rainy day fund that could come in good use here. Are you speculating that this manifold will flow better than the de-k?

btw, why is there a upper, center, and lower for the pathfinder IM on carpart.com

 

It is a 3 piece IM. It should be better than the DEK. It is true dual runner. Thus for boosted people you could just run off the short runner when boosted.

 

The VQ40 manifold is basically the same as the FWD VQ35 manifold. Definately NOT interchangeable. Unless the lower will bolt upto the VQ35 heads.

 

wow, it looks de-k inspired in terms of material and color
http://www.infinitihelp.com/ownershi...es/05015-1.jpg

so i'm assuming you'd need the vq35 version lower, center (MT version), and upper to run?

 

The VQ40 manifold is the same "split plenum" design as the VQ35 FWD manifold.

 

But plastic ...

 

Why ole why did you muddy the water with the VQ40.

VQ35 Pathy uses same low angle intake port style heads as VQ30s and the VQ30 LIM was confirmed by Stephen to bolt on to the Pathy VQ35, so you'd just use the Pathy VQ35 LIM/intake manifold.

The injectors/lower gasket are identical. You could possibly need to massage the VQ30DEK fuel rail for clearance on the Pathy LIM.

 

Ok, what about the coil packs, wouldn't the regular VQ30 rear ignition coils be too tall?
Would the rear Pathy or VQ35 ignition coils work if to tall?

 

the coils sit close to the valvecover, the IM should clear over it and you should be able to run the plugs underneath.

doesn't the 2k2's require complete removal of the IM to access the rear coils?

 

..

 

The coil packs or more specifically the length of the 'Cigars' is relavent to the cylinder heads more so than anything else. You can put longer (VQ30) cigars on VQ35 coils to use on VQ30 heads and vise-versa but there is rarely any need to do so.

 

Just the upper. I think mine comes off in under 5 mins.

 

What is the 3.5 Pathy rated at power wise? I think it can be done, but hood clearance could be an issue. My 2k2 IM barely fits under the hood.

 

240hp/260tq

it will probably all come down to hood clearance.

 

We must have Pathy engines in our 5.5g Maximas judging from dynos (- the dual runner IM)

 

What are you guys doing for idle control when you put these late model intakes onto your early VQ30's? Don't they have a different type of setup for that?

thanks,
allen

 

So besides hood clearance, the VQ35 pathy IM should bolt upto the VQ30 without any major modifications?

If thats the case, I think this might be on the list for the summer.

 

Stock IACV...

 

If you all need any specific photos of anything on the Pathfinder VQ35, just send me a PM. I have a 2001 Infiniti QX4 (same engine).

Since I have a 3rd gen, all of this swap talk is of little use to me, but very interesting.

 

You could always swap the high-port heads and intake manifold from a 350Z into your QX4.
