How much power does the AMS Performance Nissan GT-R short block support?

The AMS Performance Nissan GT-R short block (VR38 Stage 5 Billet) supports up to 2200 whp and 1350 lb-ft with a recommended 9000 rpm rev limit. It is a 4.3L big-bore stroker built on the AMS OMEGA-spec billet block for the highest-horsepower GT-R builds.

What makes the Stage 5 AMS Performance Nissan GT-R short block a billet short block?

The Stage 5 AMS Performance Nissan GT-R short block is built on the AMS OMEGA-spec aerospace-grade billet block rather than a sleeved factory block, with alloy steel splayed main caps, a skirted design, 98mm big-bore ductile iron sleeves, and a Bryant billet stroker crank for 4.3 liters. It is the same block used in the world's first 6-second GT-R.

Is the AMS Performance Nissan GT-R short block a service that uses my engine?

Yes. The AMS Performance Nissan GT-R short block is a build service that uses your existing engine as a core, so you must send core parts in. Specifically, a usable set of oil squirters must be sent in as core parts for the Stage 5 Billet Short Block.

Why is the AMS Performance Nissan GT-R short block a 4.3L?

The AMS Performance Nissan GT-R short block uses AMS 98mm big-bore ductile iron dry sleeves and a Bryant billet stroker crankshaft (94.4mm stroke) to raise displacement to 4.3 liters from the factory 3.8L. The larger displacement improves spool times and low-end torque.

Which R35 GT-R models does the AMS Performance Nissan GT-R short block fit?

The AMS Performance Nissan GT-R short block fits all R35 GT-R models from 2009-present, including USDM, JDM, Gulf, and European models in both LHD and RHD, across the CBA, DBA, EBA, and 4BA chassis designations, all based on the VR38DETT twin-turbo V6.

Description

AMS Performance VR38 Stage 5 Billet Short Block for R35 Nissan GT-R

Nissan GT-R short block from AMS Performance is the VR38 Stage 5 Billet, a 4.3L big-bore stroker short block built around the AMS OMEGA-spec billet block for the ultimate high-horsepower R35 GT-R builds on the VR38DETT platform. This AMS Nissan GT-R short block arrives as a complete rotating assembly, pre-assembled for simple installation and produced with the latest in-house technology in a temperature- and humidity-controlled clean room. Meticulously reinforced to withstand the power and torque of AMS’s OMEGA and ALPHA packages, it combines the aerospace-grade billet block, 98mm big-bore ductile iron dry sleeves, a Bryant Racing billet stroker crankshaft, and gas-ported Manley pistons to support up to 2200whp / 1350lb-ft at a 9000 rpm rev limit. Note this is a build service that uses your existing engine as a core.

Why the AMS Performance Nissan GT-R Short Block?

AMS has leveraged its racing background to set a new benchmark for the VR38DETT, and the AMS Nissan GT-R short block is balanced, blueprinted, and assembled to the standards of AMS’s 3,000+ WHP race cars, with rigorous block inspections and a detailed spec sheet for every build. As the Stage 5, it is the first short block in the range built on the AMS OMEGA-spec billet block rather than a sleeved factory block: the same block featured in the world’s first 6-second GT-R and the ALPHA Omega GT-R. It steps well above the Stage 4 short block, pairing the billet block with a Bryant billet stroker crank and gas-ported Manley pistons for up to 2200whp.

The Aerospace-Grade Billet Engine Block

The R35 GT-R billet block at the heart of this AMS Nissan GT-R short block represents the pinnacle of engine technology. It is designed with alloy steel main caps and splayed bolts for optimal load distribution, plus a skirted block design for supreme crankshaft support. Custom ductile iron sleeves and thickened walls handle extreme pressures while enhancing displacement to 4.3 liters for improved spool times and low-end torque over the standard 3.8-liter factory engine. For those aiming to compete at the highest levels, the AMS VR38 Pro Billet Series block is the starting line.

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.
