New in stock! GReddy Fuel Delivery Tubes

      GReddy R35 High Flow Fuel Rail Set.  (Part Number:13923101)

The factory R35 fuel rail has a restrictive boss with in the tube which interrupts the fuel flow for high power application. GReddy Fuel Delivery Tube will improve the flow capacity by straightening the main tube with the injector center line as well as increasing the inner diameter of the main tube to 14mm. We were also able to increase the inner diameter of the connecting line to each bank to 10mm by using AN8 fitting and -8 Teflon lined fuel safe hose.

• With the included flanged fittings and -8 AN fittings you can mount the factory fuel pressure regulator and the dampener right on the rail or customize with upgraded fuel pressure regulators.
• By separating the mounting bracket from the main tube, the mounting height are adjustable, keeping the original injector mounting angle.

* The adjustment range is 2.5mm above and 3.5mm lower from the original factory injector position.
* When using upgrade injectors on factory fuel rail, the mounting brackets needs to be modified by slotting out the holes, but due to the injector length differences, and by the fuel rail being mounted crooked (not perpendicular to the injector boss), there are possibilities of fuel and/or air leak.

GPP SPL CNC Machined VR Cylinder Heads

   Computer Matched Combustion Chambers

We have found that the factory cylinder heads has quite a bit of variance in volume from chamber to chamber and left to right bank due to the casting. We offer Japanese CNC machined combustion chamber to match each combustion chamber for the perfect balance from cylinder to cylinder and from left to right bank and improving the chamber design for optimal combustion for responsive and high power engine. Each cylinder heads are scanned and digitized to properly machine the necessary area for perfect combustion chamber. The CNC program was designed by an engineer who has over 20 years of experience building and machining race/high performance engine and cylinder heads for well known JDM tuner's cars to GT race cars. ($2600 with core exchange)

This GReddy VR Service Includes:

CNC machined combustion Chamber
CNC valve seat cut
Resurfacing

  * We can also offer ported and big valve combination for extra charge.

TCM LC1 Reflash Service by GReddy USA

      Need your 4500rpm Launch control back?


Adding to our list of in-house services like the VR Engine Building, and GR6 Transmission Upgrading, we can now also offer our GReddy TCM Reflash Service...

GReddy USA has been offering TCM reflash service to tuners for their project cars.
If your TCM has been reflashed to LC2 by Nissan dealer and you want your LC1 back for the 4500rpm launch control, we can reflash it for you.
LC1 reflash only works on 2009 model cars at this time.

We also have V-Spec data that will work for 2009-2011 model years. The launch control rpm is not raised. (LC2)

Cobb AccessPORT will still work after this reflash.

Please contact GReddy MasterTech dealer, PM us on NAGTROC.org  or email greddystaff@greddy.com for price and for more information.

NOTE: GReddy will not be responsible for damaged transmission due to high rpm launch or racing. These are not modified TCM data. They are all factory data that are being reflashed. We recommend upgrading the transmission with Dodson parts (at least the first gear) for LC1 high rpm launch. We are offering transmission service in house as well. We are one of Dodson Motorsports Proshop here in the west coast. Since we have to reflash the TCM directly to the unit, we have to break the seal which will void any warranty on the unit.

R35 Power Extreme-GS Stainless-steel Exhaust

Enhance the sound of the VR38 engine in the R35 GTR,
        with a Stainless-Steel GReddy Power Extreme –GS exhaust. (p/n 10123224)

The PE-GS is a full Stainless-steel version of our popular high-flow PE-Ti for the (R35) GTR. The system features the same diameter piping and routing in a more conventional construction and a lower price. The layout starts with a large 80mm (3.15”) mid-pipe to a dual 80mm “Y” to two tuned, straight-through, oval GReddy mufflers and exit via two more 80mm “Y”s and quad- 115mm (4.5”), inner-rolled, bolt-on GReddy exhaust tips.

GReddy Billet Pistons

Strongest piston set now available! option for GReddy Engine Program

We now have 2 piston options to choose from for our engine program.

Piston Option1: GReddy Custom Forged JE Pistons
Piston Option2: GReddy Exclusive Billet JE Pistons (Pictured Below)

We have teamed up with JE Pistons and Dynamic to develop the strongest pistons sets possible for extreme monster builds. The design and development took almost a year to complete but it was worth the wait! We took our VR block with our stroker cranks to JE Pistons back in April of last year to start development of forged and billet pistons sets for our engine program and we requested JE to perform Finite Element Analysis (FEA) for development of these pistons to test the stress and fatigue on a computer model before production. Each billet pistons are machined out of a block of high quality 2618-T6 aluminum. 100% CNC machined part means every surface are machined allowing for all unnecessary weight to be removed to keep the piston lighter but stronger. The piston features internal and external struts for improved durability and strength.

These billet pistons are not for everyone, but if you are targeting over 1000HP, you might want to consider these. Why billet over forged? To make forged pistons as strong as these billet pistons, they will be heavier which will affect the response and acceleration. By machining every surface, billet pistons can achieve the highest uniformity of material thickness on skirts and general body, which results in improved heat dissipation caused by stress concentrations experienced in high boost / high power engines. This is not possible with plain shaped forgings on a high production pistons.

For such extreme build, why not get the strongest piston available. Due to the production process and the development costs, it does cost more than forged pistons but if you are looking for the most durable and strongest pistons for 1000+HP that will withstand up to 1600+HP, these are the ones you want!

These options are available for all GReddy Engine Program (3.8L, 4.0L big bore, 4.0L Stroker, and 4.2~ 4.4L Big Bore Stroker) and are not available by it self.

More new products coming soon from GReddy!

Now that more and more GTR owners are building their vehicles for high power applications, our R&D team in Japan and US have been busy developing more upgrade parts for the R35 GTR.
We will soon release few upgrades for high power applications and some of these prototypes will be displayed at this week's Tokyo Auto Salon in the GTR display area but here is a sneak previews of one of the item.

GReddy Billet Big Bore Throttle Bodies
With all the recent developments and release of various turbo upgrades and modified engines for monster power, we are now starting to exceeded the capacity of the factory throttle body to take full advantage of this increase of flow and volume.

There are many modified factory throttle bodies out in the market already but the maximum diameter these factory throttle bodies can be machined out to is 63mm due to the factory castings (factory ID is 60.5mm)
We are currently testing 70mm and 75mm throttle body with 80mm inlet diameter. GReddy Billet Big Bore Throttle Bodies will utilize adaptor flanges to make these big bore possible on the factory manifold (with minor modifications). We are also working on high capacity intake manifolds as well. These throttle bodies are CNC machined from forged, billet 6061 aluminum and will be hard anodized for durability. They are designed to use the factory internal motor mechanism and cover for simple plug-in application and tuning. Features precision machined parts for super smooth operation and flow for maximum flow and quality.
Made in Japan


Large throttle bodies are the key to produce additional power throughout the powerband and maximizing the potential of the modified engines with upgraded high flowing turbochargers.

More images and data will be posted soon.

GReddy Fuel Delivery Tube
Factory fuel rail has an inside diameter of 11mm but around the injector mounting section they are reduced to 6mm restricting the flow for high power application.
GReddy Fuel Deliver Tube are designed to support good fuel supply for upgraded injectors with 14mm inside diameter. It also features a bracket system that will ensure proper fitment of the injectors. Mounting them perfectly perpendicular to the injector mounting boss on the cylinder heads.
