Why buy a GT2871R Turbocharger without an actuator?

Builders who already own an actuator, want a different spring rate, or are replacing a damaged turbo on a car with a working actuator often skip it. This GT2871R Turbocharger is listed by Turn 14 without one. If the housing is internally wastegated, the engine must not run until an actuator is fitted.

What is the GT2871R rated to make?

Garrett rates the GT2871R at 280 to 475 horsepower on 1.8L to 3.0L engines, using the choke flow of the compressor map to estimate potential flywheel horsepower. The turbine housing, boost level, fuel and calibration on a given engine decide the actual output.

Which turbine housing is fitted?

Garrett does not publish it for 836026-5011S, and the Turn 14 listing gives no A/R or flange. We confirm the configuration with the distributor before ordering. Garrett documents the GT2871R fully in 0.64 and 0.86 A/R, which may suit a new build better.

Which actuator should I use with it?

Garrett catalogues 480009-0009 at 0.5 bar, 480009-0006 at 1.0 bar and 480009-0010 at 1.5 bar. Turn 14 pairs other GT2871R numbers with the 0.5 bar and 1.0 bar units. Confirm the housing first, then choose the spring rate to suit the boost target.

What else will I need for installation?

Beyond an actuator where the housing needs one, plan for oil feed and drain lines, coolant lines to the water cooled center section, gaskets and flanges that match the manifold and downpipe, and an updated calibration. A Garrett speed sensor kit is optional and sold separately.

Description

Garrett GT2871R Turbocharger, without Actuator

Garrett’s GT2871R Turbocharger under part number 836026-5011S is the version Turn 14 lists without an actuator, for a builder who already has one or plans a different boost control setup. Because 836026-5011S does not appear in the current Garrett GT2871R tables, its housing size, flanges and wastegate layout have to be checked with the distributor, which we do before any order is placed. The family data Garrett does publish covers the 53mm compressor inducer and 71mm exducer, the 54mm GT28 turbine wheel, and a power rating of 280 to 475 horsepower for engines between 1.8L and 3.0L.

Features

Supplied without an actuator, per the Turn 14 listing
53mm GT2871R compressor wheel with original GT Series aerodynamics
Ball bearing configuration with a water cooled CHRA

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.
