Description

The BoostLogic GT1R GEN 2 FLEX FUEL KIT is a second-generation flex fuel system designed for the R35 GTR.

This kit features a completely plug-and-play wiring harness, utilizing Mil Spec tefzel wire and Raychem DR-25 heat shrink for durability. The flex fuel converter box translates the ethanol sensor's signal into a 0-5v output compatible with the stock ECU, offering .5v for 0% ethanol and 4.5v for 100% ethanol. The kit includes all necessary plumbing with Redhorse Performance ethanol-compatible hose and crimp ends, the ethanol content sensor and mount, and the plug-and-play harness. Options are available for stock or aftermarket fuel rails, with adapters for AN threads or specific ORB sizes.
