But if thats not true they would be the best choice and i would gladly use them.

I *MIGHT* be able to get that IACV piece duplicated if that's the difficult part for people to make themselves.

But that's just me. Until I see pictures and irrefutable proof I am not convinced.

The VK56 uses the same size valves as the VK45 even though it has a much larger bore of 98mm. If the VK56 used ti valves it would be better because I have better access to Nissan parts as opposed to Infiniti parts.

I am very interested in this.
I currently have two complete 4th Gen engines sitting in my garage that I could use to test fit the DEK manifold on until it is perfectly set on......
Hmmmm, darn you Krismax for making this work lol. Now I will be spending more money......tisk tisk tisk...... ......Thanks BTW......

I can't use the VK intake valve in my VQ35 because the face is 1mm smaller but I can use the exhaust valve if I shave the stem to make it shorter. The reason behind that is the VK45 valves are longer than VQ35 valves but shorter then VQ30 valves.

samoylov installed 2K engine into his 4th gen but with 4th gen IM and you installed 5th gen VI on the 4th gen engine. Logical answer I guess it could be done....

Actually, I take that back, it has NOT been done.
I was mistaken. maxS and vsamoylov were talking about the same car...didn't know that until I looked:
http://www.cardomain.com/memberpage/444152/4
So, it was a -K engine withOUT the manifold. My bad.

Kris,
GLad to hear you got your project working! I think I'll leave the restrictive plate out of my 2000 intake. Good work.
What is a "TRUE" variable intake?
If I were call a maxima intake "true" I'd say the 2002 not the 2000.
The 2000 maxima intake seems to function similar to the mevi. It just has a different profile. The 2000 runners arch higher and the air box is under the runners where the mevi the runners a flatter and the air box is on top.
What am I missing?

True variable intaKe is in the 5th gen maxima, SHO's, ect...

I read about the Main differences compared to the VI but I lost the thread.

Two different length runners for each cylinder from the main plenum chamber.
The 2000-2001 DEK manifold has a flap that covers the shortest runner that once it receives vacuum and ECU signal above 5000rpm opens and allows the shorter runners to flow air.

I would say that the composite manifold found on the 2k0 and 2k1s is the only "true" VI with the MEVI next in line.
The 2k2 intake manifold is ghetto and does not change between different length runners.

Another thing I did was move the PCV valve on of the valve cover ,in the air seperater pics deezo posted you can see the PCV valve right out in the open.
I was thinking of raising it at 5750rpm the reason i say that is because the long runner before switchover is pulling hard around 5000rpm.
Also alot of the answers for doing this are in the intake manifold swap thread.

Longer runners for low end torque.
Thaniel, the difference is that the DE-K has 2 separate runners for each cylinder while the MEVI has single runners with additional space that opens to change the sound frequencies or whatever to get more power up top.

Anyone have any nissan literature from the introduction of the 2000 maxima mentioning the variable intake? I've read stuff for the 2002 and pathfinder and they DO have 2 seperate runners. It is just not there on the 2000 (much to my surprise and dissapointment).

I've heard everybody talk about the "true" variable intake but I have fully dissasembled my DE-K upper intake and even cut part of it off and there isn't a seperate runner. The valves open to a closed box which allows one cylinder to pull air from all the runners like the MEVI. NO SEPERATE RUNNERS.

I've got one at home that I've check inside/out and I disagree.
It's got two runners. It starts from the main plenum as one runner that splits into two runners, one short into the box and one long over the top of the box, and then they join before the lower manifold. The path the air takes is determined by the valve being opened on the shorter path, which causes the air to bypass the longer runner which is still open.
Explain how that's similar to the MEVI, I don't know how the MEVI really works.
Also, you have any pictures of that disected DEK manifold?

Pull the valve system out and look into it. There is a path to the valve but when the vavle is open the path goes to a BOX that is connected to all of the runners by going back through the valve to a different cylinder. There is no second path to the Throttle body. The only way air can get to the valve is through the long tube then down to where it almost meets the lower intake. It can either go into the lower intake there or do a almost complete 180 and go up into the valve and then into a DIFFERENT cylinder. I have cut my intake through the runners. draw a line connecting the coils if you want a visual. I can look up the runners both directions. There isn't a second path.
I can try to get some pics to you if you don't believe it but if you remove the valve from the intake and look in there you will see there isn't a second path.
the diagram previously posted http://larrio.maximaclubca.com/VIAS_1.PDF agrees with what I am telling you. notice that it says "effective port length" or the 2 ports commbined act like a shortened port (or runner). There isn't actually a second port or runner.
By the way I am not saying that the 2000 intake is not better than the pre 2000. Just that it doesn't have 2 runners and that it is very similar to the MEVI.

What view is the second picture. I am guessing it is doing a similar thing then but farther up the runners. Allowing one runner to be connected to all the runners?
A few mazda cars use a similar concept. They call it VDI (variable dynamic intake).
#160
I see what you're saying, I think, but still not agreeing. You could be right, just not what I saw, but mines not cut open so it's hard to tell.
Anyways, I'll look tonight and see if I can remove the power valve to get a better look.
I don't care which is better/worse honestly. The -K just appeared to have a runner for each cylinder that splits from the plenum, takes either A or B path, and then joins before entering the lower.
Good info though~!
