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 internal components are in the AMS Performance Nissan GT-R long block?

The AMS Performance Nissan GT-R long block uses a Bryant Racing billet stroker crankshaft, Manley 300M rods and Manley pistons to AMS spec, a big-block-Chevy rod bearing conversion, ARP CA625+ head studs, an ATI crank balancer, CNC-ported heads, Tomei 282 cams, and Ferrea +1 valves with dual springs.

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

The AMS Performance Nissan GT-R long 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 4 Long Block for R35 Nissan GT-R

Nissan GT-R long block from AMS Performance is the VR38 Stage 4, a 4.1L stroker long block for the R35 GT-R built on the VR38DETT platform for peak horsepower. This AMS Nissan GT-R long block is robustly modified to endure the power and torque of AMS’s OMEGA and ALPHA packages and arrives fully assembled from valve covers to oil pan and timing components for a low-hassle drop into your GT-R. Built in a temperature- and humidity-controlled clean room around a Bryant Racing billet stroker crankshaft and CNC-ported cylinder heads, the Stage 4 supports up to 1700 whp / 1200lb-ft and is best suited to the ALPHA 18X turbo kits (up to 68mm inducers). Note that 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 over two decades of racing success to the VR38DETT to build the most formidable engine program for the GT-R. The AMS Nissan GT-R long block is balanced, blueprinted, and constructed to the standards of AMS’s 3,000+ WHP race cars, with every block extensively inspected and each engine documented with an archived spec sheet of tolerances, torque specs, and clearances. Stage 4 is the head-ported evolution of the 4.1L stroker platform: it combines the Stage 4 stroker short block with a T1 Race Development Stage 1 CNC head-porting package, Tomei 282 camshafts, and Ferrea +1 valves with dual valve springs for serious airflow and rpm capability up to 1700 whp.

Race-Winning Standards

Choosing the AMS Nissan GT-R long block connects you to over twenty years of race engine development. The short block portion uses a Bryant Racing billet stroker crankshaft (fully balanced), Manley 300M connecting rods and Manley pistons to AMS spec, a big-block-Chevy rod bearing conversion, King main bearings, main girdle reinforcement with 12mm ARP studs, new OEM timing chains with an AMS proprietary timing system upgrade, an AMS OEM oil pump rebuild with pressure modification, ARP CA625+ head studs, Cometic head gaskets, an AMS billet deep oil pan, an ATI crank balancer, and Sterling charcoal powder-coated timing covers. The head package adds the T1 Race Development Stage 1 CNC head-porting package, a Ferrea high-performance valve job, Ferrea +1 valves with dual valve springs, titanium retainers and bronze valve guides, Tomei 282 camshafts, and proprietary cylinder head and camshaft modifications.

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.
