The Pinnacle of VR38 Engines

With the introduction of exclusive AMS components, they’ve established the most powerful and reliable engine solution for the GTR, evidenced by record-setting track performances. The 4.3L VR38 Stage 4 Short Block by AMS Performance stands as the definitive choice for achieving high reliability and horsepower.

Race Winning Experience Creates Higher Standards

  • Each engine built by AMS is meticulously handcrafted, embodying the same level of care as those in their world-record-setting race cars. Choosing an AMS engine represents an investment in the extensive knowledge amassed from assembling thousands of race engines over more than 20 years. Mirroring the approach taken with their 3000+ WHP race cars, every engine is balanced, blueprinted, and assembled according to strict specifications. Prior to assembly, each block undergoes a thorough inspection for accurate dimensions, cylinder bore, main alignment, block flatness, and more, ensuring the optimal foundation for the new engine. Furthermore, AMS maintains an archived spec sheet for every engine they build, detailing tolerances, torque specifications, and clearances as a key component of their quality control process.

The numbers provided here are derived under ideal conditions with the right supporting modifications and represent achievable outcomes for the typical customer. However, individual results may differ.

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.
