AMS VR30 Stage 1 Long Block | 2023+ Nissan Z

The AMS Performance Nissan Z 3.0L VR30 Stage 1 Long Block is a fully assembled engine for high horsepower builds. AMS machines it with in-house equipment and assembles it in a temperature and humidity controlled clean room, and the engine is strengthened in several ways to handle the power of the AMS ALPHA performance packages.

It comes complete from valve covers to oil pan, including the timing chain and components, ready for manifolds and accessories. AMS uses your existing engine as the core to build from, with new OEM gaskets, seals and hardware throughout. It is best suited to stock turbo or basic turbo upgrade builds.

Build sheet highlights: blueprinted block, cylinders honed and reconditioned to size, main journals honed to AMS spec, AMS spec ARP main studs, Manley connecting rods, AMS spec Mahle pistons, OEM crankshaft inspected, Magnafluxed, polished and fully balanced, King main and rod bearings, new OEM head bolts and timing chains, an AMS modified and rebuilt OEM oil pump, smoked charcoal powder coated timing covers, and a reconditioned head with an OEM valve job, resurfaced head cases, set valve lash and GSC single conical valve springs with titanium retainers.
