How much power will the ETS Single Scroll Turbo Kit for VA support?

ETS rates the ETS Single Scroll Turbo Kit for VA from about 300 hp to beyond 1,000 hp, depending on the turbo. Its own ratings run from 650 hp for the Precision Gen 2 5558 to 1,100 hp for the 6870 and the NextGen 6670, with engine and fuel work to match.

Which up-pipe option do I need?

Choose 2-bolt if the car has the factory or an aftermarket 2-bolt manifold, 3-bolt for a Tomei 3-bolt header, or V-band if you want the ETS MaxFlow header included. BA can confirm which header is on your car before ordering.

Is the intercooler included?

No. The single scroll kit includes the 2.5 inch upper intercooler pipe under the intake manifold, but the intercooler core and the rest of the charge piping are separate. ETS pairs it with its STI front mount intercooler and rotated piping kit, both sold separately and listed on BA.

Which wastegate comes with the kit?

Precision turbo orders ship with a Precision wastegate, while Garrett and Xona turbo orders come with a TiAL wastegate. ETS also includes a 1 3/4 inch dump tube, and the downpipe has an O2 bung for the factory sensor. BA can check other wastegate options with ETS before you order.

Does it need a speed density tune?

Yes. The kit uses a 4.0 inch speed density intake, so the car has to be tuned on speed density rather than the factory airflow meter. Book a tuner familiar with the EJ257 and plan fuel upgrades to suit the turbo.

ETS Single Scroll Turbo Kit for VA Subaru WRX STI

ETS’s Single Scroll Turbo Kit for VA Subaru WRX STI rotates the turbocharger and runs it on a V-band turbine housing with a larger, ported anti-surge compressor cover, then lets the owner choose from more than twenty Precision and Garrett frames. ETS rates the kit from 300 to more than 1,000 hp depending on the turbo, from 650 hp on a Gen 2 5558 to 1,100 on a 6870 or NextGen 6670. It is the most flexible way to turbo an STI with ETS hardware, and the up-pipe option matches it to the header already on the car.

Three Up-Pipe Options

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.
