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

The AMS Performance Nissan GT-R long block (VR38 Stage 5) supports up to 1900 whp and 1200 lb-ft with a recommended 8600 rpm rev limit. It is a 4.3L big-bore stroker with T1 Stage 1 CNC-ported heads, best suited to turbo kits up to 68mm inducers, sitting between the Stage 4 and the billet-block Stage 6.

What makes the Stage 5 AMS Performance Nissan GT-R long block different from the Stage 4 and Stage 6?

The Stage 5 AMS Performance Nissan GT-R long block shares the Stage 4's 4.3L big-bore stroker bottom end on a reconditioned factory block but adds the T1 Stage 1 CNC head porting package and Tomei 282 cams for 1900 whp. The Stage 6 steps up to the AMS OMEGA billet block and T1 Stage 2 heads for 2200 whp.

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

Yes. The AMS Performance Nissan GT-R 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 is in the head package of the AMS Performance Nissan GT-R long block?

The AMS Performance Nissan GT-R long block Stage 5 head package includes the T1 Race Development Stage 1 CNC head porting package, a Ferrea high-performance valve job, Ferrea +1 valves with dual valve springs and titanium retainers, and Tomei 282 camshafts, arriving fully assembled.

Description

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

Nissan GT-R long block from AMS Performance is the VR38 Stage 5, a 4.3L big-bore stroker long block for the R35 GT-R built on the VR38DETT platform for maximum horsepower and reliability. This fully assembled AMS Nissan GT-R long block is precision-machined with the latest in-house technology in a temperature- and humidity-controlled clean room, extensively fortified to handle the power and torque of AMS’s OMEGA and ALPHA packages, and arrives ready for manifolds and accessories. Combining AMS 98mm big-bore ductile iron dry sleeves, a Bryant Racing billet stroker crankshaft, and the T1 Race Development Stage 1 CNC head porting package with Tomei 282 cams, the Stage 5 supports up to 1900whp / 1200lb-ft at an 8600 rpm rev limit. Note this is a build service that uses your existing engine as a core.

Why the AMS Performance Nissan GT-R Long Block?

AMS has applied decades of race-winning experience to elevate the VR38DETT to the highest level, and the AMS Nissan GT-R long block is balanced, blueprinted, and assembled to the standards of AMS’s 3,000+ WHP race cars, with comprehensive block inspections and a detailed spec sheet for every build. As the Stage 5, it sits between the Stage 4 and the billet-block Stage 6: it takes the 4.3L big-bore stroker bottom end, adding main girdle reinforcement with 12mm ARP studs on a reconditioned factory block, and tops it with the T1 Race Development Stage 1 CNC head porting package, Ferrea +1 valves, and Tomei 282 camshafts for up to 1900 whp. It is best suited to turbo kits up to 68mm inducers.

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.
