GT1R Gen 2 FlexFuel Kit

The second generation GT1R Flex Fuel kit  from T1 Race Development is improved in both being completely plug and play to all year model R35 GTRs, as well as the sensor being relocated to the pressure side of the system.

The sensor on the pressure side of the system gives more consistent readings in the event that return fuel flow is minimal (if you’re nearly maxing out the fuel pumps).

Updated the wiring and now offer a plug and play wiring harness.  Race Spec Wire Harnesses, the best in the business.  The harness is assembled using Mil Spec tefzel wire, Raychem DR-25 heat shrink, and new connectors for a durable and clean PNP installation.

The flex fuel converter box converts the digital signal from the ethanol sensor to a 0-5v signal that the stock ecu requires.   With this converter, the output is .5v for 0% ethanol and 4.5v for 100% ethanol.

There is no display used with this kit, as both Cobb and EcuTek allow the user to view ethanol content in their own ways.

The complete kit includes all plumbing, with high quality Redhorse Performance ethanol compatible hose and crimp hose ends, the ethanol content sensor and mount, and the PNP wiring harness.

Kits are offered to suit the stock fuel rail, or aftermarket rails.  The stock fuel rail kit includes a rail adaptor to convert the rail inlet to AN threads.  If you’re using aftermarket rails, you will need to specify what size the rail is (6AN ORB or 8AN ORB).


The perfect solution from T1 Race Development to run both 93/91 Pump Gas/ E85 in your GT-R!
