Description AMS ALP.07.04.0304-1 Short Block Stage 4 4.3L VR38 for NISSAN Z (RZ34) 2022-

The AMS Performance 4.3L VR38 Stage 4 Short Block is designed for high horsepower builds in the Nissan GTR. This fully assembled short block is crafted with precision machining using advanced in-house equipment. Each AMS built engine is strategically strengthened to support the significant power and torque produced by OMEGA and ALPHA performance packages.

Assembled in a temperature and humidity controlled clean room, every detail is meticulously crafted. The short block is ready for installation with heads, manifolds, and accessories, utilizing the existing engine as a core. New OEM gaskets, seals, and hardware are used throughout the assembly.

AMS proprietary engine components and decades of race-winning experience are applied to the VR38DETT V6, resulting in a strong and advanced engine program. Each short block comes as a complete rotating assembly, ready to install, using high quality off-the-shelf and custom AMS spec components.

Product Notes: Horsepower and torque numbers, and RPM limits are approximate and can vary significantly depending on numerous factors such as turbocharger selection, intake and exhaust restriction/backpressure, and fuel octane and quality, among many others. The advertised numbers are based on optimal conditions and proper supporting modifications, but are generally attainable results by an average customer. Results may vary.

Product Notes: In rare cases, component selection may vary from advertised based on supply chain delays. All component substitutions will be communicated in advance by an AMS Sales Representative during the engine assembly process.

Product Notes: Assumes that a good condition core is sent in to build from. This requires a usable block complete with engine girdle and oil squirters.
