AMS Performance - 2023 Nissan Z RZ34 Stage 3 Direct Injectors
The AMS Performance VR30DDTT Stage 3 Direct Injectors are the perfect upgrade to get more out of your VR30’s direct injection fuel system.
The limitations of the factory injectors become evident even at relatively lower horsepower numbers, especially when using ethanol-based fuels like e85. AMS Performance recognized early on in their development of the VR30 engine platform that they would need to provide more fuel to support more power.
Developed in collaboration with Nostrum High Performance, an industry leader in fuel system technology, the AMS VR30 Direct Injectors deliver industry-leading build quality and performance that our customers can rely on.
ENGINEERED TO BE THE BEST
The AMS VR30 Stage 3 Direct Injectors have been engineered to be a direct fit, OEM injector replacement that requires no fuel rail or electrical adapters to install. The AMS and Nostrum Calibration Teams have also gone the extra mile to ensure the Stage 3 Direct Injectors are easy for tuners to calibrate with the supplied injector calibration data. AMS Performance's product engineering and calibration data combined allow the AMS Stage 3 injectors to achieve cold start and drivability characteristics on par with the OEM injectors by utilizing a next-generation spray pattern, expertly engineered specifically for the VR30DDTT engine application.
CONSTRUCTION AND MATERIALS
The AMS VR30DDTT Stage 3 Direct Injectors are derived from brand new OE manufacturer direct VR30DDTT HDEV5 injector cores. As these injectors come via the OE supply chain, they have VR30-specific, factory-correct, overmold, and fuel rail features, allowing for a perfect OEM fitment. During the entirety of the Nostrum manufacturing process, each injector and its subcomponents are serialized, QR-coded, and tracked to allow for full traceability. AMS and Nostrum are so confident in the construction of these units that a Limited Lifetime Warranty¹ against manufacturer’s defects is included at no additional cost to ensure your investment.

Put it to the Test
What sets this and every AMS component apart from the competition is our rigorous battery of R&D testing. The AMS VR30 Stage 3 Injectors have been tested for thousands of miles in multiple vehicles, including countless 1/4 and 1/2 mile runs, before being given the green light to release to the public. Our AMS Engine Calibrators have spent hundreds of hours testing these injectors in vehicles in order to refine them with Nostrum High Performance for maximum fueling performance and vehicle drivability. In addition to this research and development testing, all AMS VR30 Injectors are bench tested, including static flow testing and multi-point dynamic testing, by Nostrum. The injectors are then batched dynamically to reduce variation in flow, further improving wide-open-throttle and idle performance, as part of an extensive quality control process.
