This adapter is simply a replacement of the lower intake manifold to allow us to bolt on the R35 GT-R intake plenum (collector), and that's just the beginning.

:iagree: Can't wait! :tup:

thats true - this lower intake manifold will allow you to "simply" install the factory GT-R R35 plenum on the VQ37HR engine.

When everything is finished, test fitted and dyno tested I hope that I can offer a kit which consists of:
- the CNC-machined / hand-welded full aluminum lower intake adapter VQ37HR heads-to-VQ38DETT plenum
- 2 fuel rails with your choice of -6AN / -8AN / -10AN fittings and lines
- all needed gaskets, bolts, washers, etc.
- detailled pictured installation manual (maybe I will do a vid for youtube also)

key aspects of the conversion kit are:
- designed and development with CAD
- computer-simulated and calculated flow optimization
- smooth edges, improved injector spray, equal length runners, largest possible diameter runners, perfect gasket match, blue printed, etc.
- CNC-machined and hand-welded in Germany by a company which produces turbine parts for Airbus aircrafts
- you can use your stock injectors, stock FPR, etc. or you can easily convert to a dual feed / return system
- by using -6AN billet aluminum fuel rails with the stock injectors you optimize fuel delivery even with the stock fuel system
- all sensors, vac lines, etc. can be attached
- stock throttle bodies will fit the GT-R R35 manifold w/out modifications, you only have to shorten your stock intake hoses / aftermarket intake pipes

what I will do for testing is the following:
- dyno my car with the stock manifold
- dyno my car with the GT-R R35 manifold and adapter installed
- dyno my car after a custom tune re-flash with UpRev

I have no real clue yet if and what this conversion will do to a NA car (which I have currently) but I'm 100% sure that a turbo'ed or supercharged car will benefit a lot from this upgrade !

currently I'm waiting for the parts to arrive from the production / assembly, then I will post more pics and keep you updated !

1. Which is the stock size, and for those looking to do this to a stock motor, would they see any improvement in choosing a different size?

2. Does this mean if you get an aftermarket intake Prior to installing this, you will have to trim it to fit? So it won't necessarily be "plug and play"?

3. This is for the lower piece only correct, if you plan to do the conversion you will need to order a GT-R Upper manifold and cover still correct?

Can't wait to see the final product/numbers Chris!

In for victory! Really excited to see this produce some results.

Can't wait to see this!

1. well, as the stock fuel rail can't be re-used for fitting issues your choice of two new billet aluminum rails will be included. The smallest rails are -6AN which is slightly more diameter than the stock rails have. I have not tested or evaluated if the stock rails cause any problem but at least it won't hurt.

Of course when it comes to larger injectors you will benefit a lot and as those rails are avail up to -10AN there is much room to grow.

We will use Aeroquip fittings and lines to connect the rails to the stock or an aftermarket FPR - a hard line with fittings will be used to connect the rails from right to left. So it is very easy to run two separate lines to each rail if you want to upgrade to a dual feed system later.

2. yes thats true as the position of the throttle bodies doesnt match the stock location - they are about 5cm / 1.9" more forward towards the front. So if you have like a STILLEN GEN3 you need to cut the pipes by this length to keep the stock MAF sensors in place.

I have a STILLEN GEN3 here myself so when the installation process starts you will see pictures of what modifications are needed. But I try to keep the installation effort as low as and to make this as much PnP as possible.

3. correct, this is "just" the adapter so you are able to install the GT-R manifold. Many people asked me meanwhile if it won't be easier / more effective to do a whole new manifold lower AND upper part together.

Well, of course we could have designed a whole new part and but the idea was to make the GT-R plenum fit the 370Z - that was and still is my personal challenge and whatever comes out at the end of the day I will achieve this goal.

Furthermore our engine and the GT-R engine arent so much different and with the GT-R intake NISSAN developed supports well over 1000HP in the most current setups from tuners like PHR, BL, GReddy, AMS, AAM, etc. - they all keep the stock intake manifold and plenum so I guess and cant be too wrong.

BTW the stock R35 plenum is about $600 new from NISSAN but you can find it around eBay for less than half this price.

this would be a fun mod for a frontier :stirthepot:

in for results, good luck :tup:

1. Will the larger fuel lines/rails/injectors be too much for the 'stock' pump to power for those remaining NA for the time being? Or would it be something that can be included in the maps when getting UpRev tuned?

2. Looking forward for the complete install. :tup:


Two thoughts, is this a project for someone considering staying NA to even consider if the possible gain was marginal, and just made a much better looking intake manifold for aesthetics?

Secondly, With the GTR having a different strut bar than the Z, would it be somewhat of a tragedy to get this, and then just be covering the manifold with the stock strut bar? I wonder if there was a way to make another strut bar that would go 'around' the cover vs directly over it... :icon08: :confused:

In for a finish!

in for results, Would like to see what gains are on a NA car, I would custom my Stillen Intake and runs this if he makes good gains, :)

Hurry up and finish it already! :bowrofl: Tired of :drool: over this.. :tup:

:icon18::bowrofl::bowrofl::bowrofl: :tup: :iagree:

YEAH!! :yum::icon14::mad:
