AMS Performance VR38 Pro Series Billet Bare Block for R35 Nissan GT-R

For 23 years, AMS Performance has been a pioneering force in the automotive aftermarket industry, particularly in forced induction technology. Their performance systems have set the bar for quality and innovation.

AMS Performance has leveraged its winning experience from the race track to elevate the R35 GT-R’s VR38 V-6 engine to unparalleled heights with the introduction of the Alpha R35 GT-R Pro Billet Series Block Upgrade. Utilizing a bespoke Alpha aerospace grade billet block, they have created the most robust and advanced engine block available for the GT-R, establishing world records in the process. For those seeking the ultimate engine block for the GT-R, AMS Performance offers an unmatched solution.

Unmatched Construction

  • In their quest to construct the ultimate GT-R block, AMS Engineers focused on two objectives: achieving unmatched power capabilities and ensuring reliability at those power levels. They selected billet aluminum for its superior strength and ductility. Manufactured in America from a single billet aluminum piece, this material stands up to the extreme pressures and temperatures generated by engines producing over 3000 horsepower.

The Pinnacle of Performance

  • The AMS Performance R35 GT-R Billet Block represents the zenith of performance. Featured in the world’s first 6-second GT-R and the celebrated AMS ALPHA Omega, the block serves as the cornerstone of champions. It incorporates alloy steel main caps with splayed bolts and a skirted block design for exceptional crankshaft support. The design includes custom ductile iron sleeves and reinforced walls for increased displacement to 4.0 liters, enhancing spool times and low-end torque. For those aiming to compete at the highest levels with a Nissan GT-R, the AMS Performance VR38 R35 GT-R Pro Billet Series Block is the starting point.

Ultimate in Efficiency

  • Efficiency is key at the power levels this block supports, where extreme heat can diminish horsepower. The billet aluminum’s excellent thermal stability efficiently manages heat, maintaining performance. AMS Performance has a proven track record with its engines powering the fastest R35 GT-Rs to 6-second quarter-mile times. The VR38 R35 GT-R Pro Billet Series Block is essential for achieving extreme power.

Race Winning Experience Creates Higher Standards

  • The engines from AMS Performance are a testament to the precision and high standards of their race-winning vehicles. Choosing an AMS engine means joining a legacy of over two decades of racing engine development. Each engine is carefully balanced and blueprinted to match the performance of their race vehicles. AMS conducts thorough inspections and maintains detailed records for each engine, ensuring the highest quality standards are met.

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.
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.
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 with any inquiries.
