Show original supplier description
The Nostrum 2.0L Turbo GM Ecotec LTG - Stage 1 Fuel Bundle (NHP-H186-1321) provides a significant upgrade for Full Bolt On (FBO) E85 builds, eliminating E-blend headaches and offering headroom for safe power tunes. This bundle combines the Standard Bore HPFP kit (part #H086-0676) with Stage 1 GDI Injectors (part #H703-1256) to create a comprehensive direct injection fuel system. The HPFP kit includes a high-pressure pump with an OEM quick-connect fitting, mounting flange, alignment tool, electric harness adapter, stainless-steel high-pressure tube, and all necessary hardware. The Stage 1 GDI injectors are dynamically flow-tested, batched, and serialized sets. Key features include direct replacement injectors with an OEM equivalent spray pattern and pumps that are 100% dynamically tested for traceability. The system boasts a +36% HPFP fuel flow capacity and +20% injector fuel flow capacity, supporting up to 550 WHP on gasoline and 410 WHP on E85. This bundle is also compatible with high-lift camshafts, specifically mentioning support for a 0.2" lift ZZP cam. A tune is required for this system, with HP Tuners recommended as the tuning suite. Nostrum advises working with a tuner experienced in aftermarket direct injection fuel systems for optimal calibration.
