Cool RJM GTR Intake Conversion

In the effort for more power we here at RJ MFG have developed the most efficient and proven power making GTR Manifold conversion. This conversion allows the user to bolt up a 2008+ OEM Nissan GTR manifold, Greddy Intake Manifold, AMS Carbon Fiber Manifold and etc... There is only one aftermarket manifold not currently supported and that is the Boost Logic Manifold (The Boost logic design does not line up to factory locations). The longer Runners and larger cross section of the GTR conversion manifold is a massive improvement over the OEM design. Opening up the opportunity for forced induction clients to make more power in the mid range and low end. This conversion also allows users to run more Boost than the factory manifold can handle (30+ psi).

Hundreds of hours of R&D:




100% MADE in the USA and In STOCK!


What is included:

Gasket Kit
Balance Tube
Balance Tube Flanges
Hardware Kit
Fuel Rails
Oil Cap



MSRP: $1995 +Shipping


June Sale Price: $1895 +Shipping

At this moment this is recommended for FI Application only. We are testing the N/A application and once final testing is complete we will open this up to the N/A community.

Can you still run the strut brace with a GTR manifold?

Jay,

this is from my build swapping From the prototype GTM to the RJM and a retune:

Torque:


HP:


Same dyno (Dyno Dynamics 16% observable loss from DynoJet) and same weather... We were able to remove any and all restrictions from the intake side allowing us to make way more mid range TQ and HP!!!

Chuck,

At this point and time no you can not. However, we are developing a few prototype replacements. In real world experience I have run this for 2 years with no front strut brace and have not noticed any loss in rigidity.

We also have over 12 units on customer cars at this point in time. Thus far we have only heard positive reviews on gains. This is about a 2 hour install from start to finish.

Do you have anyone with a more normal turbo setup testing this? The results above are awesome, but a little hard to relate to given the level of modification of the test car.

Yes we have seen 50whp -100whp increases due to this mod on stock motors from HR to VHR with a tune. All cars have seen decreased spool time and depending on the turbo setup they have seen various gains in their mid-range and top end. Each turbo setup will have different gains but they have all had consistent gains everywhere in the powerband. The company test car saw 50whp with a minor tune. That is a 350z HR with a single turbo and 9 psi of boost.

I will see if I can get some dyno charts from customers to help you guys visualize. The 4.5L is definitely showing an exaggerated affect this plenum has against the competition. Rest assured its one of the best bang for your buck mods on a turbo or even SC car.

You think? He gained another VQ37 worth of power. Was that still with the GTM setup or the FI?

Is this lower the same height as the OEM GTR lower? The runners the same length? Any pic of this conversion in a 370z? Any plans to offer versions with polished internal runners. All 370z OEM manifold connections retained on GTR upper manifold?
