Welcome to the new GReddy GR9 Blog!
This blog is dedicated to GReddy's quest for the ultimate street rocket R35 GTR!
On this blog we will update you on own GPP (GReddy Performance Products) Project GTR as well as other R35 products and builds.
Check back with us often, because there is a lot going on in the R35 tuning market. The GReddy-GR9 Blog is your #1 source for tuned R35s!
GReddy is proud to introduce a new update to the popular GReddy 94mm Titanium Exhaust for the R35 GT-R. In addition to a name change, the new system now features 10mm larger quad 125mm (4.9”) burnt Titanium tips, to better fill up those GT-R rear tip cut outs. The system maintains it's proven design. It's has great performance for upgraded GT-Rs but still comfortable for milder, daily-driven GT-Rs. The large dual oval mufflers provide excellent sound suppression and sound quality, while large piping frees up power for the twin turbo VR engine. It also comes with a huge dual 80mm (3.15") to 94mm (3.7") Y-pipe. The construction is made-up of carefully hand-built 94mm piping is pain-painstakingly "inch-welded" for excellent fitment and flow. The ideal exhaust for the R35 GT-R is the 94mm GReddy Supreme Ti ! P/N 10128294 2009-14 Nissan GT-R (R35) Supreme Ti - 94mm $ 5495.00
NGK Part # 22401-RS080-09 GReddy Part # 23000009 MSRP $49.95ea.
One of the best spark plugs you can find for a highly modified R35 GT-R. Proven to perform on many GReddy 35RX builds. The NGK Racing Spark Plugs in a colder, Heat Range 9 is an ideal design for powerful VR builds. A redesigned angled ground strap has provided improved anti-smoldering or fouling characteristics.
These VR Specific NGK Racing Spark Plugs feature a 0.55 Electrode Diameter, an electrode constructed with a Iridium center & Platinum exterior, and a built-in resistor.
The "Long-reach" plug type measures 12mm diameter X 26.5mm long for the threaded section and it uses a 14mm socket size.
GReddy DCT Cooler Kits are ideal for quick DCT fuild warm-up, while maintaining more consistent DCT temps. This in turn, proves better life for both a modified or a non-modified DCT (Dual Clutch Transmission)
The kit features our famous Blue (inner-fin) large 13row core mounted in front fender. It also includes a FRP divided air duct, (similar to the OEM unit on the other side of the car,) for maximum cooling.
Installation is easy thanks to specialized GReddy R35 trans oil block. The internal thermostat insures quick fluid warm-up and consistent oil temps, and does not tax the standard coolant system.
Carefully designed light-weight -14 hard-lines & braided-lines allow for a minimal routing lengths and maximum flow. Completing the kit are all the necessary mounts, hose fitting and 3 piece billet flanges with o-rings.
A few weeks back we shared on our blog that we were invited by a major Automotive magazine editor for a supercar comparison, well the editor was Sam Mitani of Road & Track magazine and the challenge was to compare four elite Tuned Supercars (GMG Audi R8 LeMans TT, D3 Cadillac CTS-V Coupe and CEC Mercedes-Benz SLS). We were happy to represent Japanese Tuners with our 4.3L GReddy Twin Turbo R35(GR43 GT-R) And as you can see from the results below, with some help from KW suspension, Whiteline, SP Engineering, Dodson, Rays and Toyo, we did quite well...
But when it came time for performance test, we dialed the PRofec boost controller back to about 20psi, for the car to be more manageable for the magazine test drivers. Even still the results were impressive. 0-60 in just 2.45sec. and the 1/4mile in just 9.9sec. Sam Mitani said "...this car beat the $2.7 million Bugatti Veyron Super Sport (November 2011 issue) to 60 mph and to the quarter mile, the GR43 can be regarded as something of a bargain." (this is the 2nd time we had a driver tell us our GT-R was faster then a Veyron)
The GR43 also had the best 0-100mph time, shortest braking distances (thanks to the TopSecret rotors), and even though the car was more set-up for a short road course then, a skidpad or slalom, we recorded the top Lateral Acceleration of 0.99g and just short of the best Slalom, by just 0.4mph (73.1mph).
Look for the full article "Performance Overload" in the next Road & Track issue.

Late last month at the annual GT-R Magazine's R-meeting, we debuted the GReddy 35RX GT-R with a 200+mph pass and Tarzan Yamada at the wheel. Here is a quick video excerpt of the GReddy 35RX on a practice run (a few days prior) along the famous Fuji Speedway straight-away.
Here is just a quick teaser of the sound our GReddy 4.3L VR powered R35 V2 makes on low boost & 91 octane fuel. We'll have more updates in a few weeks about what this was for...but until then; TURN UP THE VOLUME and enjoy!
Back in May, the GPP staff was out supporting the efforts of one of our GR-Master Tuner Shops, SP Engineering, in their efforts for a GReddy-Powered, 8sec quarter-mile R35. Although the the track conditions were not quite right for 8s, we have been working hard to get back on a track and go for it again! Below is a recent article from Autoweek about our quest!
In AUTOWEEK By DAVID ARNOUTS on 7/20/2011
"Eight seconds can seem either like an instant or an eternity. For SP Engineering, however, eight seconds is the threshold it aims to cross in its highly modified Nissan GT-R shop car for the standing quarter-mile. “This car will run eights,” said Will Wong, wholesale manager at SP Engineering. “The problem is traction, getting the power to the ground.” But SP continues to try a variety of suspension settings and tires in an effort to reach its goal. Even with a full interior and ice-cold air conditioning, the street-legal GT-R pumps out more than 1,150 all-wheel horsepower through the Mickey Thompson drag-radial tires. Having broken the previously long-held dyno horsepower records, SP went on to hold the world record for GT-R quarter-mile time with the SPE900 GT-R in April 2010--9.62 seconds at 149.8 mph. A stock 2012 Nissan GT-R will run the quarter-mile time in the low-11-second range... Rival tuner shop AMS Performance of Chicago in May 2011 took the current record with a 9.1-second run at 163 mph with its flagship Alpha 10 GT-R. Since then, SP has consistently been hitting the 9.2-second mark with its SPE1000 setup, inching closer to the ever-elusive eight-second barrier. “With the right [elevation] and a good 60-foot launch, the SPE1000 can do very high eights, we believe,” Wong said. SP plans to debut its top-of-the-line Godzilla package on track in the next month in another attempt to break the eight-second barrier. Piloting the SP Godzilla GT-R will be longtime customer and hot shoe Hing Yim. If you have deep enough pockets and a strong stomach, you can have your own Godzilla GT-R for just less than $100,000. More than 20 kits have been ordered". (update: the current record is 9.05 @ 166)
Used in GReddy built big bore complete VR engines.(p/n 13521401)
GReddy VR Metal Head Gaskets features a stopper type center layer to completely seal the cylinder by adding extra torque around each cylinders.
Outer layers are coated with a thin layer of nitrile rubber to ensure good seal to the head and deck surfaces.
Designed to with stand high boost and power. These are now used in all of our big bore complete engine builds. *(also Sold Separately)
Available bore sizes:
Part #: 13521401 99mm t=0.8mm (for 98.5mm bore pistons)
Part #: 13521402 100mm t=0.8mm (for 99.5mm bore pistons)
** Custom thickness are also available for additional cost.
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.
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.

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.
Many have asked us recently; "What does it take to run 9sec quarter mile times in a street-trim R35?" Well since we've already done it, below is a list of the upgrades, we have made to our own GReddy GR9 R35 GTR.
Currently our car is now being fitted with and testing the next level of GReddy performance goodies to hopefully propel us in the the 8s shortly! These same parts will be available to R35 owners very soon. Please check back with our GReddy-GR9 Blog for more updates as they happen.
List of our GR9 upgrades on the stock VR38DETT motor: 835awhp
Recently, the GPP staff found a little time to also bring out our GReddy R35 to the Drag Strip for some testing. And we are happy to report it did very well for it's 1st trip out; easily making it into our GR9 club (9.76@149.85mph). We now look forward to taking the build to the next level! Look for more big news very soon.
Until then, here is a little video we pulled together with our GoPro and SLR Cameras. Enjoy!
It's known that a good free flowing exhaust, like our 80mm (3.15") full Titanium GReddy PE-Ti can add great performance to at GTR. But now that we have opened up the power to over 1000hp & 9sec Quarter Mile runs, with our twin TD06SH-20G turbo upgrade, we've decided to offer a huge 94mm (3.7") straight through Titanium exhaust, that is still quiet and comfortable for everyday use.
The dual large straight-through Ti mufflers provide excellent sound suppression.
This version also comes with a huge dual 80mm (3.15") to 94mm (3.7") Y-pipe.
Carefully hand-built 94mm piping is pain-painstakingly "inch-welded" for excellent fitment and flow.
GReddy burnt Titanium Logo and quad staggered Tips complete each 94mm R35 GReddy Racing Ti System.
