AMS Performance VR30 Red Alpha Pro Series Engine

Description

Overcoming catastrophic block failure requires the AMS Performance VR30 Red Alpha Pro Series Engine and its iron-sleeved 3.0L displacement. Feel absolute confidence in your bottom end during aggressive track passes and dyno pulls. Eliminating mechanical structural weakness on the drag strip allows this compliant race block to utilize a precision CNC-machined OEM aluminum casting to anchor 1000+ HP twin-turbo setups reliably.

Engine Architecture & Core Specifications

• Block Material: OEM cast aluminum VR30DDTT, precision CNC bored, honed, and fitted with heavy-duty ductile iron sleeves.
• Cylinder Heads: Ships as a short block; designed to accept factory aluminum direct-injection heads.
• Compression Ratio: Maintains optimal compression for off-boost drivability and extreme boost tolerance.
• Bore & Stroke: 86.0 mm bore x 86.0 mm stroke (3.39 in x 3.39 in).
• Rotating Assembly: Custom forged aluminum pistons, extreme-duty forged connecting rods, and a micro-polished factory forged crankshaft.

Component Breakdown: Built Short Block

• Upgraded aftermarket cylinder sleeves prevent cylinder wall cracking under massive boost pressures.
• Custom heavy-duty forged aluminum pistons resist extreme combustion temperatures and prevent ring land failure.
• Extreme-duty forged rods eliminate bending during violent low-end torque spikes.
• Upgraded race-spec main and rod bearings distribute heavy rotational loads effectively.
• Premium ARP main studs provide maximum clamping force to secure the rotating assembly.

Vehicle Fitment & Compatibility Matrix

Engineered as a direct-fit replacement for factory VR30 chassis, this block accepts all OEM accessories without heavy fabrication. Securing one of our high-performance crate engines guarantees a factory-level installation for high-boost repowers.

• Fits 2023-Present Nissan Z RZ34 models utilizing factory twin-turbo setups.
• Fits 2016-Present Infiniti Q50 chassis including Base Premium Sport and Red Sport 400 trims.
• Fits 2016-Present Infiniti Q60 chassis including Base Premium Sport and Red Sport 400 trims.

Fuel & Ignition System Requirements

• Upgraded high-pressure fuel pumps and high-flow injectors are required to match massive airflow capabilities.
• Minimum 93 Octane pump gas is required though E85 is heavily recommended for maximum forced-induction performance.
• Factory OEM coil-on-plug ignition systems plug right into this block.
• One-step or two-step colder spark plugs must be gapped properly to prevent spark blowout.

Installation, Break-In Oil & Priming Instructions

• Transfer existing cylinder heads using fresh MLS gaskets and torque everything to exact factory specifications.
• Fill the crankcase with a premium high-zinc break-in oil to protect fresh bearings.
• Disable the fuel and ignition systems before cranking the engine in short intervals until mechanical gauges show steady oil pressure.
• Reconnect systems to fire the engine while checking for leaks immediately and maintaining a varied RPM between 1500 and 2500.
• Drain the initial oil after the first complete heat cycle and refill with high-zinc oil while avoiding wide-open throttle for the first 500 miles.

USA Warranty, Emissions & Logistics

• This built engine requires a usable and crack-free OEM VR30DDTT block core exchange to validate the purchase.
