GTM Performance Engineering: GTR Manifold Conversion

This is why I love GTM

Looks like ChrisUR's hardwork and time and money invested just went to waste as GTM has just trumped him with a finished and released project. Especially as he was saying his was going to be minimum of $1200. Nice work GTM. Sub'd for results

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?

I can't wait to see the final product.

Exactly. Having more options is always a good thing.

GTM,

Will the Greddy RX Upper Intake Manifold for GTR application work with this lower?

tibal · 07-25-2013, 10:24 AM

Awesome!! I cant wait to see results on both Na and Boosted Application. Interested for sure.

Hey Sam, you know, my car is a virgin test car at your shop...

ZMan8 · 07-25-2013, 11:04 AM

In for some test results on N/A and Turbo applications

Megan370z · 07-25-2013, 11:30 AM

Good job on the lower intake manifold ! I might be very much interessted into this !

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.*

COSMO · 07-25-2013, 12:34 PM

Very interested but almost 2k in parts alone and Iam almost certain a us with FI will need a retune of at least $600 unless your going to offer a revised map?? Most of us are on a stock block so even more power would seem like a waste. Hell what do I know.......................@#$%^&*

Yes, it will work with the 7AT.

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.

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.

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.

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.

soo nice but soo expensive!

Well, what's more important- the cost or the power it makes? Guys here spend $1500 on a catback that gives them 10 whp. If this turns out to make 20 whp, is it then not a better value?
