Will the GBC20-300 Club Line Turbocharger suit a 2.0L engine?

Yes, at the top of its range. Garrett rates the GBC20-300 Club Line Turbocharger for 0.8L to 2.0L engines, so a 2.0L engine is the largest it is sized for. Builds on a 2.0L that want more than about 300 horsepower should look at the GBC22-350, which shares the outline.

What horsepower does Garrett quote for the GBC20-300?

Garrett quotes 170 to 300 horsepower in its reference data for this model. The figure is based strictly on the choke flow of the compressor map and represents potential flywheel power, so the engine, fuel, boost and calibration decide the real result.

What flanges does the GBC20-300 use?

A T25 turbine inlet and a 5-bolt outlet. Garrett lists the matching T25 inlet gasket, 447802-0001, and 5-bolt outlet gasket, 770119-0001, along with an oil outlet gasket. The turbine housing is a 0.55 A/R open volute design with an internal wastegate.

How is Club Line different from Garrett G-Series?

Club Line uses journal bearings and internally wastegated housings and is engineered for small displacement engines. G-Series uses ball bearings, larger wheels and offers free-float housings. Club Line is the simpler, lower-output family, suited to engines that do not need G-Series flow.

Which actuator comes with it?

Garrett includes the 480009-0009 actuator, a 0.5 bar unit, with Club Line turbochargers. Stiffer 1.0 bar and 1.5 bar actuators are available separately as 480009-0006 and 480009-0010, for builds that need a higher spring baseline to hold boost against exhaust pressure at high rpm.

Description

Garrett GBC20-300 Club Line Turbocharger, 0.55 A/R T25 Internal Wastegate

Garrett’s GBC20-300 Club Line Turbocharger is the middle of Garrett’s Club Line, with a 39mm billet compressor wheel, journal bearings and an internally wastegated 0.55 A/R turbine housing with a T25 inlet and a 5-bolt outlet. Garrett rates it at 170 to 300 horsepower on 0.8L to 2.0L engines. It suits a 1.5L to 2.0L four-cylinder that wants a straightforward upgrade, or a large powersports engine at the top of its range. For engines that already make 300 horsepower it runs out of compressor, and the GBC22-350 is the next step.

Compressor Design

Garrett uses a billet compressor wheel with an extended tip design on the GBC20-300 for higher pressure ratio capability, and pairs GTX Gen II compressor aerodynamics with modern gasoline turbine wheel aerodynamics. The rotating group runs on journal bearings rather than a ball bearing cartridge.

Features

39mm billet compressor inducer with a 52mm exducer
T25 turbine inlet and 5-bolt outlet, outline interchangeable with the GBC17 and GBC22
Internal wastegate assembly with a calibrated 0.5 bar actuator

Specifications

Compressor inducer and exducer: 39mm and 52mm
Compressor A/R: 0.59
Turbine inducer and exducer: 47mm and 42mm
Turbine trim and A/R: 84 and 0.55
Turbine inlet and outlet: T25 and 5-bolt
Bearing system: Journal bearing

Applications

The GBC20-300 Club Line Turbocharger is not vehicle specific. Garrett sizes it by engine and output:

Engine displacement: 0.8L to 2.0L
Power range: 170 to 300 horsepower (Garrett rating)
Engine types Garrett names: Powersports, personal watercraft and automobiles

Notes

Garrett states that the GBC power figures are calculated from compressor choke flow and represent potential flywheel power
Garrett lists optional 1.0 bar and 1.5 bar actuators for higher boost baselines, sold separately
The oil inlet gasket is not part of Garrett’s gasket list and must be sourced to suit the oil feed
Step up to the GBC22-350 on the same outline for more power

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.
