This means you can enhance your Toyota Supra without compromising its integrity. The ALPHA 8 Turbo Kit is fully compatible with factory options such as A/C and Power Steering, allowing you to maintain the functionality of your vehicle’s original features. Moreover, if you ever decide to revert back to the stock configuration, it can be easily accomplished with a few inexpensive replacement parts. The superior design of the ALPHA 8 Turbo Kit positions it as the market’s top performer, offering exceptional quality and the added advantage of hassle-free installation. What sets the AMS ALPHA 8 Turbo Kit apart is its full compatibility with the high-quality AMS 3″ Charge Pipe, 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 8 GTX3582 GEN II Turbo Kit, where exceptional exhaust flow is achieved through the use of 1.5″ ID 304L stainless steel schedule 10 piping. This handcrafted piping is meticulously fabricated to ensure optimal flow efficiency. To simplify installation and ensure leak-free operation, a v-band connection is seamlessly integrated into both the manifold and turbine housing. Furthermore, AMS has ingeniously designed this kit with an internally gated system, eliminating the need for an external wastegate design. This not only eliminates any additional weight but also minimizes flow disturbances that are typically associated with external wastegates.
  • The AMS SnailWorks© Engineering Team has skillfully designed a downpipe that incorporates a gradual taper from 3.5″ down to the factory exhaust joint, effectively minimizing excessive back pressure. This downpipe, constructed from high-quality stainless steel, is precisely TIG welded and showcases a v-band connection. It also features a 3.5″ flex section with a smoothly finished internal liner, a GESI G-SPORT catalytic converter that complies with EPA regulations, and an 80mm slip joint designed to match factory specifications. This intelligently engineered design ensures a seamless and hassle-free installation, as it serves as a perfect bolt-in solution for your existing exhaust system. Additionally, the inclusion of the flex joint allows for natural engine movement, reducing the risk of broken welds or exhaust hanger issues.

The Garrett© GTX Series Turbo

  • The Garrett© GTX-Series turbos have earned a solid reputation in the performance turbocharger market, known for their impressive horsepower output and quick spool time. Among them, the new GTX3582R ALPHA 8 turbo kit stands out as it is capable of delivering over 700 whp* while maintaining excellent boost response and the renowned reliability associated with the Garrett© brand. The GTX GEN II compressor wheels have been meticulously designed using advanced computer simulation technology, specifically focusing on CFD analysis. This process ensures that the wheel design is optimized for maximum efficiency and mass flow for each turbocharger. As a result, each GTX GEN II turbocharger can generate higher air mass flow, offering enthusiasts a wider range of power output options when tuning their vehicles. Furthermore, the inclusion of the 8mm dual ceramic ball bearing cartridge enhances turbo response and reliability by minimizing shaft motion.
  • In order to enhance power output, the Garrett© GTX3582 Gen II turbos in this system feature a 4″ inlet and a 2.5″ discharge compressor cover. This design allows for superior airflow compared to smaller turbo systems equipped with a 3-inch cover. By incorporating race-proven Garrett© turbos, AMS has effectively increased horsepower across the entire powerband. To provide added convenience during installation, their team has gone above and beyond by pre-installing the oil and water lines to the CHRA (Center Housing and Rotating Assembly) and carefully positioning the compressor cover. This attention to detail not only saves you time but also ensures a smoother installation process.

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.
