Is the GT2554R Ball Bearing Turbocharger complete?

Yes. Garrett lists 836023-5001S as the GT2554R turbo, sold as a complete unit including the turbine kit and actuator. It comes with a 0.80 A/R compressor housing and a 0.64 A/R internally wastegated turbine housing around the ball bearing center section.

How much horsepower will the GT2554R make?

Garrett rates the GT2554R Ball Bearing Turbocharger at 170 to 270 horsepower on engines from 1.4L to 2.2L. The figure comes from the compressor map choke flow and represents potential flywheel horsepower, so fuel, boost and calibration decide the real outcome.

Does it need an external wastegate?

No. The 0.64 A/R turbine housing has an internal wastegate and Garrett supplies the actuator with the turbocharger. Boost is controlled at the turbocharger itself, so the exhaust manifold does not need an external wastegate flange, and a factory-style manifold without one can be retained if the flange matches.

Should I buy the GT2554R or the GT2560R?

Both share the same turbine wheel and a ball bearing center section. The GT2554R uses a 42mm compressor inducer for the quickest response on small engines. The GT2560R steps to a 46mm inducer for more airflow, which suits a 1.6L to 2.5L engine aimed a little higher.

Why choose a ball bearing turbocharger?

Garrett highlights the GT2554R as its smallest ball bearing configuration, with a water cooled center housing. A ball bearing center generally responds faster than a journal bearing design, which is why the GT2554R is a common choice where low-speed boost matters.

Description

Garrett GT2554R Ball Bearing Turbocharger, 0.64 A/R Internal Wastegate

Garrett’s GT2554R Ball Bearing Turbocharger is the complete GT2554R, part 836023-5001S, supplied with a 0.80 A/R compressor housing, a 0.64 A/R internally wastegated turbine housing and the actuator. Garrett calls it the smallest ball bearing configuration in its range, built on a water cooled center section with a 42mm compressor inducer. Rated at 170 to 270 horsepower on 1.4L to 2.2L engines, it is a strong match for a small four-cylinder where boost response is the priority. A 2.0L build aimed past 300 horsepower will outgrow it, and the GT2560R or a GT28 frame is the next step.

Original GT Series, Ball Bearing

The GT2554R pairs original GT Series aerodynamics with a ball bearing center section. Because the turbine housing is internally wastegated and the actuator is fitted, the turbocharger needs no external wastegate, which keeps installation straightforward on compact engine bays.

Features

Complete turbocharger with turbine kit and actuator
Ball bearing center section, water cooled
42mm compressor inducer with a 0.80 A/R compressor housing

Specifications

Compressor inducer and exducer: 42mm and 54mm
Compressor housing A/R: 0.80

About Garrett

Garrett Motion has turbocharged engines since 1955, when its T15 was matched to the Caterpillar D9 crawler, and in 1962 a Garrett turbocharger went into the Oldsmobile Jetfire Turbo Rocket, the first turbocharged production car. Garrett has supplied turbocharging in Formula 1 with Scuderia Ferrari, the FIA World Rally Championship and the 24 Hours of Le Mans. It has operated as a stand-alone company since 2018, and its technology is fitted to around 150 million vehicles worldwide.

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.
