Prevailing Tech Themes of the TX2K12 GT-RsWith an army of fully loaded Nissan GT-R R35s, T1 Race Development (T1) undoubtedly brought the troops to battle and was looking for a full-on altercation. While their heavy hitter was unable to appear due to developing a hairline fracture during the tuning session just moments before departure, T1 certainly did not come up short. All four of their featured R35s were able to dip well below the ten second mark—no easy feat.
T1’s natural evolution from its industry-leading import drag legacy to the versatile and power-hungry R35 platform is evident through their four features. Through a proven process of progressive iteration, T1 is constantly evolving these four builds to provide a fully competent and reliable performance solution for their R35 kits.
Given that all four of these packages are technically still works in progress, many of the technical details have not been released, as they are constantly evolving. T1 fabricates much of their builds in house, while relying on their technical partners to do what they do best and manufacturing their parts based on specifications engineered by the T1 crew.
Similar to one of the prevailing themes, all four of these vehicles are running E85. T1’s take is to provide the Zeitronix sensor and gauge, which allows the system to monitor the ethanol content and report it back to the driver. While they have not incorporated a true flex-fuel solution, this allows the driver to rely on the factory computer to run closed-loop control off the O2 sensor input, thus allowing for a significant variance in ethanol content. In the event that content falls below the optimum range, the driver is notified and takes it easy to prevent catastrophic engine failure. Under high-boost applications, it is very important it is to be cognizant of the ethanol content.
While several of these features contain variances in their turbo kits, T1 is confident that future kits will be nailed down with the following: the GT1R 3E Series package will utilize the stock manifold with an upgraded turbo cartridge and the GT28 turbine wheel. Both of the future GT1R 4E and 5E Series packages will include T1’s upgraded cast manifolds, while the 4E will be GT30 based, and the 5E can be either GT35 or T37 based.
Tony’s 2009 Nissan GT-R R35
Tony’s R35 is an iteration of the GT1R 3E series package. This includes the upgraded turbo cartridge with the GT28 turbine and the HTA71 billet compressor wheel connected to the stock manifolds, which dump into the 4’’ T1 stainless steel exhaust system. Tuned in house utilizing the COBB AccessPort to run E85, the fuel system had to be upgraded to meet the higher fuel delivery demand. This includes Injector Dynamics 2000 injectors, T1 fuel rails, and the T1 triple fuel pump system.
To get power to the 21" iForged Sprint wheels on the street or the 18" Volk TE37SLs on the track, an upgraded transmission was in order. To accomplish this task, Tony’s R35 had the Stage 2 transmission manufactured by Shepherd Transmission installed.
For a bit of visual steez, Tony had the 2012 front bumper conversion installed with the Stillen front lip and wrapped the entire vehicle in a supersleek matte grey wrap.
Tony was able to put down 760 awhp on the T1 Mainline AWD Dyno and clocked a best ET of 9.91 seconds @ 145 MPH during the TX2K12 event.

According to Tony Palo, the limiting factor currently in the build is the twin turbo HKS GT800 turbo kit complete with an HKS intercooler and piping kit. This power plant dumps into the superlight Greddy 94mm titanium exhaust system.
The COBB AccessPort was utilized to dial in the E85 tune with the ethanol content being measured by the Zeitronix system mentioned before. This allows the Injector Dynamics 2000 injectors, T1 fuel rails, and the T1 triple fuel pump setup to deliver adequate fuel to the combustion chamber.
Picking up the mammoth weight of the vehicle would be the 18’’ VOLKE TE37s for the track or the 20’’ HREs slated for the street. As with any build of this magnitude, T1 installed the Stage 4 transmission manufactured by Shepherd Transmission.
Put it all together, and Shin’s ’09 puts up 840 awhp on the Mainline AWD Dyno with a best ET of 9.49 seconds at 150 mph at TX2K12—currently the holder of the T1 Race Development record!

Tuan’s R35 is one step closer to the future GT1R 4E Series package, as it has T1’s upgraded cast manifold and the T1 spec GT30-based upgraded turbo with the Greddy enlarged intercooler and piping kit. The HKS Legamax exhaust system expels the gases to maximize the twin turbo’s efficiency.
The stock engine management system demands the Injector Dynamics 2000 injectors, T1 fuel rails, and the T1 triple fuel pump setup to deliver the E85 fuel as required by the COBB AccessPort tune. As with several of the other builds, T1 incorporated the Zeitronix sensor system to alert the driver of any variances in ethanol content.
The 18’’ CCW wheels wrapped in MT Drag Radials are driven by the Stage 2 Shepherd Transmission upgrade.
Tuan’s GT-R was able to clock in a best ET of 9.78 seconds at 153 MPH with 908 awhp on demand.

Reza’s GT1R 4E series-powered R35 utilizes the Greddy turbo kit with the T1 spec upgraded GT30 turbine twin turbos. The spent gases are expelled via the Greddy 94mm titanium exhaust system.
During the event, it became apparent that the turbo inlets were a largely limiting factor in the build and will be resolved upon their return. T1 has also acknowledged that the build will significantly improve with larger cams. Once this portion of the project is complete, they expect nearly 100 extra horsepower.
On the demand side, the COBB AccessPort tune demands the identical T1 upgraded fuel system to deliver the required amount of E85 fuel. Reza's build also employs the safety ethanol-monitoring Zeitronix system.
During the drag event, Reza’s R35 actually broke fifth gear. It’s clear that the upgraded first gear was not enough, and in the future T1 will be installing a full 6ppg gear set to deliver the dependability required for such a versatile platform.
During final testing, Reza’s build was able to achieve 905 awhp on the Mainline AWD Dyno and put down a best ET of 9.50 seconds at 140 mph (on the pass that broke 5th gear!) and a 9.55 @ 155 mph earlier in the day on the TX2K12 drag strip.
