VQ37VHR intake manifold???
 

What does it look like inside? Does anyone have an exploided view of the manifold? Does air from the right side and left side throttle bodies ever mix?

My ultimate question is: How is boost equalized between the right bank of cylinders and the left bank on a twin turbo set up. Most of the intercoolers I've seen look like they keep the incoming air seperate from one another.

Yes, the air is allowed to 'mix' inside the plenum.

Are there any baffles inside?

:google: your best bet for the answer

I really can't remember. All I know is that the two sides aren't completely sectioned off. I can take a pic inside the plenum tomorrow when I get to the shop (it's off a 350zHR engine which uses the same plenum). I'm redoing a bunch of the stock wiring in the engine bay, so I just happen to have my plenum off the car.

found this instead... a forged VQ37 block

OK, that's just sexy!

I've googled this before with no luck. Here is as far as I've gotten.

They call it the "Intake manifold collector", and "Intake manifold". I will call it the upper and lower intake manifolds. Exact same idea that Ford built for the 5.0L over 20 years ago.

I found these pictures long ago but they don't tell me what the upper half looks like inside. I think these are the ones you were talking about. I just want to know how the two sides equalize. I want to find a dissected view of the upper half.

Like I said, I'll get some inside pics tomorrow :)

That would be awesome because I've asked this question several times before on myg37 and no one knows.

Ivoidwarranty, I completely forgot to take some pics while I was at the shop :o

I will be back up there on Saturday, so I promise to get some pics then. I'll tie a string to my finger to remind me :icon17:

It would be nice to see someone make an intake man. thats kinda like the gt-r's

I'm assuming that with those pistons being numbered, they're balanced...Wow...in any case.

I wonder what that cost...lol

That's cool, I've been waiting a year for this answer, a couple more days won't hurt.

Here are pics of the HR iplenum, which is basically the same as the 370's plenum.

+1 to failsafe for the pics

Help me out here; So it looks like it's an open chamber (from both sides???) with ports that lead down to the lower manifold.

If I wanted to, could I weave a wire from one throttle body opening to the other throttle body opening?

Exactly.

Absolutely. On a couple of those pics, I stuck a flashlight inside one TB, and took a pic from the other TB, and you can definitely see a good deal of light making it through the plenum.

Thanks. That answers my question that no one has been able to answer for the last year.

NP :tiphat:

Thanks failsafe! +1

Rise from the grave!!!
 

Instead of going OT in the Kinetix thread, I'm reviving this thread specific to the GT-R's intake plenum. It took me awhile to figure out how the GT-R intake plenum (manifold?) connected to the cylinder heads and how we got the square cutouts with our intake plenum. That 2nd piece on our VQs (intake collector from prior posts?) is pretty much the missing piece of the puzzle that takes us from the square cutout of the intake plenum to the round cutouts entering the cylinder head.

I'm not knowledgeable in this area so I may get my terminologies mixed up... but this is quite fun. It reminds me of the Honda hybrid builds back in the day.

So let's say we eliminate this "intake collector." I wonder how the GT-R intake manifold will sit in our VQ37. One member mentioned seeing a picture of a VQ37 with a GT-R intake manifold.

Pricey... but sound fun. It'll be somewhat close to building a hybrid, or an idea to get rid of the intake collector and feed the intake runners directly to the cylinder heads.

easiest way if it can be done is too make a .5inch alluminum spacer that has studs in the locations to hold on the vr38 upper and bolts down to the vq37 lower intake manifold. then just port it from the round upper holes to the square lower holes.

Oh yea, I got :icon14: last night (sleepy) forgetting to take another look at the VR38 intake manifold thinking that we'd ditch the VQ37 lower. That makes much more sense, but then I got to thinking about those temps...

Let Sam in on this thread, because GTM was working on a conversion. It is up on their site but no price. Not sure if they are done or not though, or even if it is do-able at this point.

temps? easy as putting thin phenolic spacer for a gtr on before bolting down the upper.
