With its superior design, the new Toyota Supra ALPHA 6 Turbo Kit emerges as the top performer, exemplifying the highest quality standards and offering effortless installation compared to other kits available in the market. What sets the AMS ALPHA 6 Turbo Kit apart is its complete compatibility with the high-quality AMS 3″ Charge Pipe that you may already have installed, eliminating the need to purchase a charge pipe twice as required by some competitors.

Hand Fabricated Tubular Exhaust Manifold and 3.5″ Downpipe

  • Introducing the AMS Performance A90 2020 Toyota GR Supra ALPHA 6 GTX3076 GEN II Turbo Kit, where exceptional exhaust flow is achieved through the use of 1.5″ ID 304L stainless steel schedule 10 piping that is meticulously handcrafted. This precision fabrication ensures the creation of the ultimate exhaust flow for optimal performance. Seamlessly integrated into both the manifold and turbine housing is a v-band connection, providing a hassle-free installation process and ensuring leak-free operation. Moreover, AMS has ingeniously designed this kit as an internally gated system, eliminating the need for an external wastegate. This not only avoids the additional weight associated with external wastegates but also minimizes flow disturbances that could arise with such designs.
  • Engineered by the skilled AMS SnailWorks© Engineering Team, the downpipe exhibits a gradual taper from 3.5″ down to the factory exhaust joint, effectively eliminating excessive back pressure. Constructed with precision through TIG welding, this downpipe is crafted from durable 3.5″ stainless steel. It incorporates a v-band connection, a 3.5″ flex section with a smoothly finished internal liner, a GESI G-SPORT catalytic converter that complies with EPA regulations, and a factory-style 80mm slip joint. This design offers a seamless bolt-in solution to integrate with your existing exhaust system, while the flex joint accommodates natural engine movement, effectively reducing the risk of broken welds or exhaust hanger issues.

The Garrett© GTX Series Turbo

  • The Garrett© GTX-Series turbos are renowned for their exceptional performance and quick spool time, establishing them as a proven and reliable turbocharger lineup from Garrett©. The new GTX3076R ALPHA 6 turbo kit is specifically designed to deliver over 600 whp* while maintaining excellent boost response and the renowned reliability associated with Garrett©. The advanced GTX GEN II compressor wheels are the result of Garrett Motion’s proprietary computer simulation technology, which focuses on CFD analysis to optimize the wheel design for maximum efficiency and mass flow in each turbocharger. With the GTX GEN II turbochargers, enthusiasts benefit from increased air mass flow, providing a wider range of power output options when tuning the vehicle. Additionally, the inclusion of the 8mm dual ceramic ball bearing cartridge significantly reduces shaft motion, resulting in optimal turbo response and improved reliability.
  • For enhanced power output, the Garrett© GTX3076 Gen II turbos incorporated in this system feature a 4″ inlet and 2″ discharge compressor cover. This larger cover design facilitates superior airflow compared to the more common 3-inch covers found in smaller turbo systems. By integrating race-proven Garrett© turbos, AMS has effectively delivered increased horsepower across the entire powerband, providing a noticeable performance boost. As an additional convenience, their team has taken extra measures by pre-installing the oil and water lines to the CHRA (Center Housing and Rotating Assembly) and expertly positioning the compressor cover. This thoughtful approach not only saves you valuable installation time but also reduces the effort required for a successful installation.

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 [email protected] with any inquiries.
