It's not completely finished yet... They are still working on the Strut brace, which ChrisUR at least has a posted design that is track tested. His kit (as he said once), will come with a strut bar as well. Or he will partner with a US manufacturer if one will work with him so they're made locally.

Good competition helps spurn progress as we've been waiting for GTM to release some info on this for what, 2 years now?

:tup:

I can't wait to see the final product.

Exactly. Having more options is always a good thing.

Yes, it will work with the 7AT.

$2k for the kit ? :icon14:

all right... let's wait for the testing results.

Considering that the OEM GTR upper plenum is $958 by itself, are you really that surprised?

EDIT: Actually, now that I think about it, if the upgraded rails fit in the factory location...that means the factory rails will fit this manifold converter. YESSSSSSS.

The stock fuel rails do not work with our lower manifold. Also, the inside diameter of the stock rails is quite small.

Wait, so the throttle bodies are not in the exact same location, so my MHI TT kit will not work as a bolt on for this?

Also, is the throttle body opening on the manifold same diameter as oem throttle body?

The throttle bodies are the same for both the VHR and the VR38DETT. That said, they are in different locations and since we make our own turbo kit as well as this conversion, it's only logical for us to have the appropriate piping available for both to work together. ;)

I have two easy question. Would it be possible to know what is the diameter at the exit side of the lower intake manifold ?

Is the Oem fuel rail could work, or not ?
*if custom holding bracket were to be made localy.*

Thanks.

For your first question, that would be assuming that the port is a perfect circle, which it is not. That said, the cross sectional area of the port is 1669mm^2.

For your second question, the stock fuel rails are not compatible with this manifold. The crossover is not long enough to span the width of our lower manifold. You could cut the crossover and mounting tabs off the factory rails, weld on A/N fittings and new tabs to make it work, if you really want to.

The thing is, the inside diameter of the factory fuel rail is surprisingly small. As you can see below, we cut the crossover to get a better look at things and they are very small (~5mm =~ 0.197"). While the inside diameters of the rails themselves are 11.25mm as shown in the last picture, the restriction is in the feed lines and crossover.

I already have the cover and intake manifold, but no hardware (bolts, fasteners, screws etc). Can you supply the hardware? Will the adapter work with the oem fuel rail setup? Will the adapter come with new hardware to mate with the VHR?

That is precisely why we offer the various components for the conversion separately. You can purchase the lower manifold by itself along with one of our fuel rail setups (either -6 or -8). For the hardware, it will come with the adapter manifold.

Mike/Sam, for someone running this on an N/A setup, but in the future plans to go TT, which fuel rail setup would you recommend so they don't have to buy multiple setups? the -6 or the -8?

COSMO 07-25-2013 02:07 PM

Ouch, too rich for my blood considering I have all of the power I will ever need. Nice products though!!!

-6 will do. -8 if you are planing on doing big power on E85

No big power, 500 streetable and normal pump gas. Thanks Sam! :tiphat:

SPOHN 07-25-2013 03:37 PM

This mod the more I think about is worth the price for what you get such as the material (and the quality of it) and there's no doubt it will make power. I could see this making +15whp with tune on NA and +25-30whp on tuned FI. Not to mention this GTR manifold makes ease for direct port nitrous/ meth into the runners.

megalapagas 07-25-2013 05:51 PM

Just be on the clear, per say I intall this on my 7AT with my 18 mhi kit with my VB of course included and 25R tranny cooler, I can't go past 520hp (assumption) because my engine will go Boom?

Chuck33079 07-25-2013 06:23 PM

Your tranny will let go long before your motor blows.

Alstann 07-25-2013 06:47 PM

Sad about the OEM fuel rails not working. :ughdance:

Mike, would there be any downside to running the -8 fuel rail? I wanted to have the overhead for down the line, in case I wanted more power.

E: Also, I sent Sam a PM, but from my understanding, if I can have a shop weld on the AN fittings, just a small amount of AN stainless steel flex hose would be able to suffice as the crossover, correct? I think I should be able to get this done for a very good price, so I might go this route.

If that was the case 20+ people here would of done that years ago. Take assumptions and research facts with the search feature.

Sometimes it's not about HP all the time but efficiantcy.

Alstann 07-26-2013 04:33 PM

Some would say I jumped the gun. I couldn't pass up a deal to get my hands on one of these! :driving: And yes, it came with a balance tube. ^^

370Z JT 07-26-2013 04:56 PM

Is the balance tube necessary?
