MilenkoGT, firelife25 and myself will be putting out heads together to adapt a Porsche Cayenne Intake manifold onto a VK56. This thread will be filled with details, issues, and hopefully finishing with a easier breathing VK!
PerformanceVH
Yes! This is a work in progress, pictures gathered from this forum of both the VK56 intake manifold and Cayenne manifold have been sent to Performance VH to see how this can be accomplished.
The Cayenne manifold has worked with amazing results on a VH45DE engine and although its boosted, it never lost bottom end torque and the gains peak and average were 35-40rwhp after 3500rpms to 6500rpms.
This project won't be finished over night, and I can't really say on a time frame, however 3 or more heads(brains and input) on a project is beetter than one.
Does anyone happen to have a Titan intake manifold laying around they aren't using? If so, which year?

Most likely you will find junk yards to be the best bet. I constantly check Ebay as well and most of the time buying a new one is cheaper, especially if you want to find 07+. Maybe set up a Paypal account for folks to donate to the cause and buy a couple new ones from courtesy parts for testing. One pre 07 and one post 07. You guys can't forget about us older trucks!!! 
When I get an 07+ IM to throw on my T, you're welcome to my old one.
Smoke T's, there is no substitute.

Just wanted to let everyone know that any and all info we find out about this project, good or bad will be explained on here....."THERE WILL BE NO SECRECTS" unlike the few on here, hidding the there manifold projects and yes there is more then one......Im not out to make money on this and neither is cory.....but the more help we get the faster and smoother it will go....
Yeah and just remember, this manifold setup won't be limited to just the Titan, i'm sure guys who do VK56 swaps in drift or race cars could benefit from this as well.
I'm thinking Firelife will be the premier user of this manifold since he is a more dedicated track user than I am and some others, plus he is an 07+ with up and coming JWT Cam installation...
I'm betting the gains will be what we expect, Porsche doesn't skimp on anything they design. And just imagine when you go to a show or the track and pop your hood with the Cayenne manifold on the VK56... you know how many people are going to be extremely confused lol.
I would like to know, if any one knows off the top of their head, the exact difference between the 04-06 VS 07+ newer manifolds. What exactly was modified internally?
I'm sure there are a few guys with some 04-06 manifolds laying around who did the 07+ newer manifold swap...
Btw, i'm sure some of you are skeptics.... However, there were skeptics when the 4in CAI was made and the FT90, and even Vinyls PBMIM custom manifold, it is all trial and error and we will never know until its tried.
This also applies to custom intake manifolds and even the VK45 (FX45)...
I'm thinking there should be a common "help" within the Titan community and no secrets in to making the Titans faster... I understand how there are the ones who want to be THE FIRST at achieving the fastest track time or whatever over the other Titan, but come on... there are bigger fish to fry track wise.
Maybe one day we will see a Cayenne Intake manifold Titan VS VK45 or custom intake manifold Titan shootout lol
just as a forewarning, if your going to "hate" or be "skeptic" that is fine, your entitled... but try and see the glass half full and know that the VK56 aftermarket has flourished with great results from the DIY or Backyard Engineering guys... FT90/PGM and 4in CAI are prime examples...
I say, bring on the knowledge and Google skills! lol
Thank you for the support from you guys so far, this is awesome and even though it is a work in progress, the results will be worth the effort!
Yes, everything will be thoroughly documented and NO SECRETS or money making by anyone, it is all towards a common goal/project.

Want to say thank you to VON for providing the manifold on such quick notice lol and to each of you who have offered!
Also, a couple measurements I took earlier to help aid the process.
The Titan VK56 intake manifold flange measurements... (on my 2008.5)
-Flange height (from cylinder head to top surface) 1-1/8th inches, lets just say 1.25in since its so very close...
-Flange width is exactly 2.5 inches.
Looking from front of Titan on passenger side of intake manifold at 1st injector to the 2nd injector... centerline spacing between both injectors is 4.5 inches.
Now, some cool things about the Cayenne intake manifold, is that the vacuum hoses are located on the rear and they are the same diameter as the VK56 manifold that go from Manifold to the valve covers. That is one less headache to worry about.
Both Titan and Cayenne use Bosch style injectors which are both 14mm Viton O-rings top and bottom.
The Titan's injector is a 60mm body lenght, and not 100% sure on the Cayenne, however that is irrelevant since the Titan injectors are of larger body length and the goal is to retain as many stock parts for the easiest bolt on affair.
I myself would like to see custom fuel rails made for the Cayenne manifold swap in order to utilize the VK56 injectors for a plug and play setup. The fuel rails would most likely be round instead of the stock Square style, so ultimately we could get a better flowing fuel rail over stock.
Also, the custom fuel rail would have the crossover feed line on the front (same as on titan rails) and the return line on the drivers side (same as on Titan)
From discussion, the setup with gaskets will be Cayenne to adapter plate will use Cayenne stock gaskets, as these hold up well to even the Cayenne Turbo S setup... so those are cheap gaskets and are quality made.
From Adapter plate to cylinder head, we're thinking instead of using the Titan O-ring gaskets and having to possibly etch/CNC 4 individual gasket slots, to utilize a one piece copper gasket that can be water jetted to the exact port diameter and bolt spacing requirements to fit onto the VK56 cylinder head and provide great seal!
Which seal is what we want lol no air leaks.
These are some of the things i've been able to discuss so far. Once the VK56 manifold gets to Performance VH, then the magic will start happening and everything has been smooth so far.
There are a couple places online where used Porsche Cayenne S 4.5L intake manifolds can be found... cheapest so far is around $420 shipped... and on the high end $500 shipped (comes with TB, Fuel rails, and injectors)
Not bad considering a Porsche Cayenne TB is like $700+ brand new!
I'm sure in local salvage yards they can be found as well for possibly the same amount or even cheaper...
Some advantages to the Cayenne manifold over the VK45 so far is that the Cayenne has been proven on a VH45DE and it has less moving parts internally, no butterfly valves and no port work to be done. Not to mention the Cayenne manifold is lighter, the VK45 manifold weighs around 40-45lbs... and seem harder to come across..
Glad you guys are on board with this mod, its time to uncork the VK56 for its full potential!

im glad someone has taking the lead on the IM! I tried like hell to get motordyne to get involved with our IM through many emails and pics of the IM...
they already make one for the 370z so I thought maybe they could see the potential market for VK56DE guys...

Someone please send me a PM next Thursday to remind me of this thread. I'm stretched after coming off of a long trip and I get my expenses reimbursed Thursday. I will be able to donate a few bucks for sure. i will not take offense to the reminder either.
:teethmast I don't need one but I want to see this finished for the rest of the racers on here. I'll see what I can contribute to you all's fund. Good luck guys. Again, when I win the lotto...
That's the good thing about centris. You can use available intake manifolds with the setup unlike pd superchargers. I guess I'll fund this project also when I win the lottery. Along with giving all the racers and heavy modders the gtm kit lol
I said it before and will say it again: if you are seeking a bolt on adapter I would be more than willing to donate my time to rev-engineer the two components in Pro/E and have a CAD model available to send for a 3D print for prototype test fitment...
Good luck with the ventures, sounds like a great project!

When I did the quick CAD drawing off of some pictures MilenkoGT sent me for quote. I ran into the first issue. One of the bolts (that bolts through the adapter flange to the VK cylinder head) intrudes into the Cayenne intake port. This means we will have to move the Porsche IM front about .750"-1.000". That way we have sufficient clearance between the intake port and the counter-bore for proper gasket sealing. Once I have both manifolds in-hand, I will have a more precise idea of how much the manifold needs to be shifted front.
As for the fuel rail... I believe that for most people the factory Porsche fuel rail flow will be sufficient (whether or not we can easily adapt it into the Titan fuel system is a different story). I want to do some research into what CC the Cayenne injectors are, connector style, and how the physical dimensions compare to the VK. Who knows we could be able to run the Porsche injectors and rails. For those adding forced induction I might recommend a custom fuel rail. These issues will be addressed and researched to the fullest extent.
Stilltime: Thank you for the offer, I will keep this in mind. How do you like Pro/E?? How does it compare to AutoCad? I use ACAD '11 3D for 95% of my work and Inventor for my sheet metal designs. I do have unlimited access to a rapid prototyping machine. The only set back is the model and support material cost over $350 per each cartridge. It is usually more economical to just the part machined since it is a larger piece.
Thank you all for the support! This is a great community!

I love Pro/e, I probably have between 8-10,000 hours in it. I had tried Inventor before, and it was better for animations and mechanisms, but modeling and assemblies are Pro/e. I also tried 3D in AutoCad about two years ago, and my main takeaway from it was that there were about 15 steps for every one step in Pro/e to get a solid model, seemed to be a lot of workaround. I stick to 2D with AutoCad. I've recently been using Creo 2.0, but still refer to it as Pro/e as more people are familiar with that.

Congrat's to ya'll for getting the ball rolling on this Sweet mod. I got an 04 manifold if it's needed. would the ls7 tb work with this setup?. :coolsmile
