VQ30DET Intake Manifold
I have a VQ30DET Intake manifold on the way and I am going to take a hit for the good of the community 
I have been told that the VQ30DET Intake Manifold flows much better than the stock manifold, and so I thought it might be good for some gains. I am going to do a VQ30DET swap, but before I did, i thought I would get a baseline dyno on my 01 AE w/ a DE-K, then install the VQ30DET Intake Manifold (and make it work) and then Dyno again to see what kind of gains (if any) I was able to acheive.
The Manifold should ship to me tomorrow and I hope to have the baseline dyno done this weekend, and the Intake installed and the New Dyno done next weekend. I will post a brief How to on the install of the manifold in this thread as well as my Dyno results. It should be interesting Check back here later this week for pics of the Manifold!

I mainly want to do it just because. I have found that you never really know for sure with cars until you try it. The maxima is CERTAINLY no exception.
I still havent decided what turbo setup I will use, I might do an SC'er with high boost also, but we will see Either way, I will be using the VQ30DET Intake Manifold to keep it as JDM as possible.
I would imagine I am going to run into signifigant issues with removing the VI Intake Manifold and the ECU trying to engage the VI. If anyone could chime in with how I am going to get around not having a VIAS anymore, I would appreciate it

You shouldnt have to do anything. The ECU will just try to engage the VIAS, send the signal, and nothing will happen.
You will obviously need a tune once you do this, making up for the lack of a VIAS.

What sort of info? Just physical specs like bore, stroke, etc?
DE-K info will be in the FSM.
There's some VQ30DET info here: http://www.vq30det.com/
Pretty much google VQ30DET, and you'll find a bunch of info.

I'm so happy this is happening, and I wouldn't even be suprised if the manifold you have is the same one that I was so close to getting my hands on for this exact purpose, than the seller stopped responding once I was ready & willing w/money in hand.
Also, if you have the rear valve cover, I could use that, I'm pretty sure it would allow me (on the '02vi car) to not have a coil-wire electrical taped to a F150 sparkplug wire for cylinder#3.
Hopefully somebody will beat me to what I really want to see- a de-k manifold on a 3.5, I'll be portmatching one to a set of 3.5 heads but it's going on a 3.0
Please hurry up and do this, all you need to do is before & after runs and the actuall swap is ****, just extend a couple wires and some stupid ****.

I never said it was groundbreaking, I just want people to see what kind of gains if any they can get from just the manifold. This might be a viable option for S/C guys or guys w/ pre 00 VQ's that dont want to go MEVI or 00VI.

Ding ding ding, we have a wiener!
Now, does anyone know who he got the idea from? Here is a hint, he was banned years ago, and pretty much all his post were erased, along with any hint of his user name. He has managed to create a few new names over the years, though he thinks we have not noticed.

It will be interesting to see how it runs on a N/A motor. I reckon you'll make a fair bit on the top - but you'll lose a fair bit of low end torque due to reduced intake velocity (short wide runner vs long skinny runners)

I think you are making a good point by doing so, please let us know how it goes.

This was during Jambo's time, if you even remember him.

Why would you want the stock exhaust manifolds? You cant really use them
Update:
Dyno was rescheduled for Monday at 1:30PM (PST) This will be 3 baseline pulls. No sign of the VQ30DET Parts yet. Will report back here w/ Dyno results
(Current Mods are just a Berk Intake and Fidanza Aluminum Flywheel/Exedy Stage 2 Clutch)

Arent the VQ30det a 2 piece set-up for each manifold!? I would like to see if that would work for a turbo set-up on my 3.5. I originally wanted to try out some 350Z manifolds, but IIRC, they wont clear the firewall.
Portmatching a 3.5 dbw tb & adaptor?

Exactly! There's no difference to the VQ30 and VQ35 manifolds other than the pre cats.... So the VQ30det's are different in the way the face... towards the tranny side of the motor, which would be ideal for a VQ30 or VQ35 fwd turbo set up.
