AMS Performance VR30 Red Alpha Base Edition Engine

Description

The AMS Performance VR30 Red Alpha Base Edition Engine delivers a reinforced 3.0L (183 CID) displacement built specifically to handle massive boost pressures. Capable of supporting 800+ HP and 700+ LB-FT of torque, this precisely machined foundation anchors serious high-horsepower Nissan and Infiniti track builds.

Engine Architecture & Core Specifications

• Block Material: OEM cast aluminum VR30DDTT, precision CNC bored and honed.
• Cylinder Heads: Designed for factory aluminum direct-injection heads (heads not included).
• Compression Ratio: Maintains factory 10.3:1 compression for optimal off-boost drivability.
• Bore & Stroke: 86.0 mm bore x 86.0 mm stroke (3.39 in x 3.39 in).
• Rotating Assembly: Forged aluminum pistons, forged H-beam connecting rods, and a micro-polished factory forged crankshaft.

Component Breakdown: Built Short Block Configuration

This unit ships as a fully machined and assembled short block. Builders must transfer their existing cylinder heads, timing components, and oil pan. Internal fortifications include:

• Pistons: Custom forged aluminum pistons designed to resist extreme cylinder pressures and prevent ring land cracking.
• Connecting Rods: Heavy-duty forged H-beam rods that eliminate factory bending under massive low-end torque spikes.
• Bearings: Upgraded race-spec main and rod bearings engineered to distribute heavy rotational loads at high RPMs.
• Fasteners: Premium ARP main fasteners providing maximum clamping force to prevent cap walk.
• Balancing: Fully balanced rotating assembly to protect the oil pump and minimize harmonic vibrations.

Vehicle Fitment & Compatibility Matrix

Engineered as a direct-fit replacement for factory VR30 platforms, this block accepts all OEM accessories and mounting brackets. It serves as the ideal foundation for high-boost repowers and aggressive track applications. Incorporating one of our premium V6 replacement crate engines guarantees a precise, factory-level installation.

• 2023-Present Nissan Z (RZ34): Direct swap for factory twin-turbo applications.
• 2016-Present Infiniti Q50: 3.0t Base, Premium, Sport, and Red Sport 400.
• 2016-Present Infiniti Q60: 3.0t Base, Premium, Sport, and Red Sport 400.

Fuel & Ignition System Requirements

Supporting modifications dictate the final power output of this forged short block. To safely achieve maximum horsepower without catastrophic detonation, builders must upgrade the surrounding fuel systems.

• Fuel Delivery: Factory direct injection (DI); requires upgraded high-pressure fuel pumps (HPFP) and high-flow injectors for 600+ HP targets.
• Recommended Octane: Minimum 93 Octane pump gas; E85 highly recommended for maximum forced-induction performance.
• Ignition Type: Accepts factory OEM coil-on-plug ignition packs.
• Spark Plug Gap: Requires one-step colder spark plugs gapped down to 0.022-0.026 inches to prevent spark blowout under heavy boost.

Installation, Break-In Oil & Priming Instructions

Proper startup procedures determine the survival of the forged internals and high-performance bearings. Follow this strict pre-start protocol before firing the engine.

• Install Core Components: Transfer cylinder heads using new MLS head gaskets and torque to exact factory specifications.
• Fill Fluids: Fill the crankcase with a premium high-zinc (ZDDP) break-in oil to protect the fresh rings and bearings.
• Prime the Oil System: Disable the fuel and ignition systems, then crank the engine in 10-second intervals until the mechanical gauge shows steady oil pressure.
• Initial Startup: Reconnect fuel and ignition, fire the engine, immediately check for leaks, and maintain a varied RPM between 1500 and 2500 for the first 20 minutes.
• Break-In Period: Drain the initial oil after the first heat cycle, refill with high-zinc oil, and avoid wide-open throttle or sustained highway cruising for the first 500 miles.

USA Warranty, Emissions & Logistics

This race-spec short block requires a strict core exchange program. Builders must supply a usable, crack-free OEM VR30DDTT block and crankshaft to validate the purchase.

• Warranty Terms: Covered by AMS Performance workmanship guarantees against assembly defects (requires documented professional installation).
• Emissions: Race Use Only. Not legal for sale or use in California on pollution-controlled motor vehicles.
• Shipping Weight: Approximately 180 lbs (short block only).
• Logistics: Ships secured in a custom crate via LTL Freight. A commercial address with a forklift or a liftgate service is required for delivery.
