AMS Performance VR30 Stage-3 Long Block for RZ34 Nissan Z

AMS Performance VR30 Stage-3 Long Block for RZ34 Nissan Z

For over two decades, AMS Performance has established itself as a pioneering force in the automotive aftermarket industry, particularly noted for innovations in forced induction systems. Their performance solutions are acclaimed for setting new standards in quality and creativity.

The AMS Performance Stage-3 Long Block is the ultimate solution for high-horsepower builds. This fully assembled long block is crafted with precision machining using advanced in-house equipment, ensuring effortless installation. Each AMS-built engine is strategically strengthened in multiple ways to support the immense power and torque produced by ALPHA performance packages. Assembled in a state-of-the-art temperature and humidity-controlled clean room, every detail is meticulously crafted to perfection. By applying decades of race-winning experience to the Nissan VR30DDTT engine, AMS has engineered the strongest, most advanced engine program available.

The Pinnacle of VR30 Engines

• AMS Performance has successfully applied its race-winning experience to the Nissan VR30DDTT to deliver the pinnacle in engine programs. By developing proprietary engine components, AMS has engineered the strongest, most advanced motor program available for the Infiniti Q50 and Q60, supported by proven track times. The AMS Performance Stage-3 Long Block is the ultimate solution for high-horsepower reliability. The long block engine assemblies come complete from valve covers to oil pan to timing chain and components, making installation as seamless as possible. This proven power plant utilizes only the best off-the-shelf and custom-designed AMS spec components, adhering to exacting standards.

CNC Ported Heads for Max Volumetric Efficiency

• The AMS CNC Ported VR30 Heads unlock the full potential of the engine’s performance. Precision-engineered using advanced CNC technology, these cylinder heads offer superior airflow and combustion efficiency, resulting in increased horsepower and torque. Ideal for high-horsepower and high-revving builds, AMS CNC ported heads provide consistent, high-quality results that elevate performance. Countless hours of testing and refinement have optimized this program to utilize the latest Ferrea and GSC valvetrain components, crafted from exotic alloy materials to withstand high boost and heat, as well as the forged billet GSC S2 cams designed for high RPMs and big power. With a 61 CFM intake and 30 CFM exhaust increase in airflow over stock, the AMS CNC head program is a proven solution to improve engine airflow.

Race Winning Experience Creates Higher Standards

• All AMS-built engines are individually handcrafted with the same care as those found in their world-record-setting race cars. Choosing an AMS engine means investing in the expertise gained from assembling thousands of race engines over the past 25 years. Just like in the 2800whp+ ALPHA OMEGA Huracan, every motor is balanced, blueprinted, and assembled to precise specifications. Before assembly, each block undergoes rigorous checks for correct dimensions, cylinder bore, main alignment, block flatness, and more to ensure the best foundation for the new engine. Each assembled engine includes an archived spec sheet documenting tolerances, torque specs, and clearances as part of the stringent quality control process.

Notes

• Horsepower, torque figures, and RPM limits are estimations and can differ widely due to various influences like turbocharger choice, intake and exhaust constraints / backpressure, as well as fuel octane and quality, among other factors. The numbers provided here are derived under ideal conditions with the right supporting modifications and represent achievable outcomes for the typical customer. However, individual results may differ.
• It is assumed that a long block in good condition is provided for the build. To prevent confusion and the risk of missing parts, it is requested that all long blocks be shipped fully assembled, from valve covers to oil pan, including timing covers and crank pulley. Any components found to be in non-reusable condition will be identified and replacements will be quoted during the engine assembly process.
• Engines operated at this level will require standard service and rebuilds pending the type and frequency of usage

CARB and / or EPA Compliance Testing Not Completed

• They believe that this product is either applicable for a CARB EO exemption or complies with the EPA’s Anti-Tampering Policy, yet the necessary testing and administrative processes have not been completed at this time. Consequently, this product is not available for purchase for emissions-controlled vehicles situated within California, nor can it be shipped to addresses in California, without a completed AMS Race Waiver form.
