How much power does the AMS Performance Nissan Z long block support?

The AMS Performance Nissan Z long block (VR30 Stage-3) supports up to 1100 whp and 800 lb-ft with a recommended 8,500 rpm rev limit. It is best suited to high-horsepower turbo upgrade builds and steps up from the Stage-2 with AMS CNC-ported heads.

What makes the Stage-3 AMS Performance Nissan Z long block different from the Stage-2?

The Stage-3 AMS Performance Nissan Z long block adds AMS CNC-ported cylinder heads with a 61 CFM intake and 30 CFM exhaust airflow increase over stock, using Ferrea valves and GSC S1 camshafts for greater volumetric efficiency on high-horsepower, high-revving builds.

Is the AMS Performance Nissan Z long block a service that uses my engine?

Yes. The AMS Performance Nissan Z long block is a build service that uses your existing engine as a core, so you must ship your engine in. Provide a good-condition long block, shipped fully assembled from valve covers to oil pan, including timing covers and crank pulley.

What internal upgrades are in the AMS Performance Nissan Z long block?

The AMS Performance Nissan Z long block uses AMS closed-deck ductile iron sleeves, Manley connecting rods, AMS-spec Mahle pistons, ARP main and CA625 head studs, King main bearings, and CNC-ported heads with Ferrea valves and GSC S1 cams, all built on a balanced and blueprinted block.

Which Nissan Z does the AMS Performance Nissan Z long block fit?

The AMS Performance Nissan Z long block fits the RZ34 Nissan Z (2023-present) with the VR30DDTT 3.0L twin-turbo V6 engine. It is built to order as a core-exchange service on that platform.

Description

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

Nissan Z long block from AMS Performance is the VR30 Stage-3, the ultimate solution for high-horsepower RZ34 Nissan Z builds on the VR30DDTT platform. This fully assembled AMS Nissan Z long block is precision-machined with advanced in-house equipment for effortless installation and strategically strengthened in multiple ways to support the power and torque of AMS ALPHA performance packages. Assembled in a temperature- and humidity-controlled clean room, it applies decades of race-winning experience to the VR30DDTT engine, combining closed-deck ductile iron sleeves, ARP CA625 head studs, and CNC-ported heads to support up to 1100 whp / 800lb-ft. Note that this is a build service that uses your existing engine as a core.

Why the AMS Performance Nissan Z Long Block?

AMS has applied its race-winning experience to the VR30DDTT to deliver the pinnacle of engine programs, with proprietary components backed by proven track times. The AMS Nissan Z long block comes complete from valve covers to oil pan to timing chain and components for the most seamless install possible, using only the best off-the-shelf and custom AMS-spec parts. As Stage 3, it steps up from Stage 2 with AMS CNC-ported heads: precision-engineered cylinder heads that unlock superior airflow and combustion efficiency, with a 61 CFM intake and 30 CFM exhaust airflow increase over stock. The head program uses the latest Ferrea and GSC valvetrain components in exotic alloys to withstand high boost and heat, making it ideal for high-horsepower, high-revving builds.

Race-Winning Standards

Every AMS Nissan Z long block is individually handcrafted with the same care as AMS’s world-record-setting race cars, drawing on the expertise of thousands of race engines built over 25 years. Like the 2800whp+ ALPHA OMEGA Huracan, each motor is balanced, blueprinted, and assembled to precise specifications. Before assembly, each block undergoes rigorous checks for dimensions, cylinder bore, main alignment, and block flatness to ensure the best foundation. Each finished engine includes an archived spec sheet documenting tolerances, torque specs, and clearances as part of AMS’s stringent quality control.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
