What power level suits the G30-900 Turbocharger?

Garrett rates the G30-900 Turbocharger at 550 to 900 horsepower on 2.0L to 3.5L engines, calculated from compressor choke flow as potential flywheel horsepower. It makes most sense on engines built for 650 horsepower or more. Below that, a smaller G30 compressor will spool sooner.

Why choose the 0.83 A/R over the 1.01 A/R?

The 0.83 A/R housing brings boost on earlier, which helps a 2.5L to 3.0L engine use the big 62mm compressor on the street and at the strip. The 1.01 A/R flows more near redline and suits 3.5L engines or high revving builds aiming at the top of the rating.

Is the G30-900 a G-Series II turbo?

No. The G30-900 is a first-generation G-Series turbocharger. Among Garrett G-Series II models, the G30-725 and G30-825 share its G30 turbine, and the G-Series II G35-990 uses the same 62mm compressor inducer on the larger G35 turbine. A G-Series II route means one of those models.

Does it include the oil restrictor?

Yes. Garrett supplies an oil restrictor and water fittings with the G30-900, and this part number arrives assembled with the 0.83 A/R internal wastegate housing and a calibrated 0.5 bar actuator. The V-band manifold flange, downpipe and oil and coolant lines are separate.

Can I get this turbo in reverse rotation?

Not as a complete internal wastegate turbo. Garrett sells a reverse rotation G30-900 super core and reverse rotation free-float G30 turbine housings, so a mirrored twin-turbo build uses those parts with external wastegates rather than this standard rotation unit. Garrett lists no reverse rotation internal wastegate housing for the G30-900.

Description

Garrett G30-900 Turbocharger, 0.83 A/R V-Band Internal Wastegate

Garrett’s G30-900 Turbocharger with the 0.83 A/R housing is the largest-compressor complete turbo in the first-generation G30 range, a 62mm wheel on the 60mm G30 turbine, built with a V-band internal wastegate housing and a 0.5 bar actuator. Garrett rates the G30-900 at 550 to 900 horsepower on 2.0L to 3.5L engines. The 0.83 A/R is the more responsive of its two turbo housings and suits a built 2.5L to 3.0L engine aiming near 700 horsepower. Engines that will never pass 550 horsepower lose response with a compressor this big and are better on a G30-725 or G30-825.

Construction

The G-Series compressor aerodynamics give the 62mm wheel a maximum efficiency of 77 percent by Garrett’s figures. The turbine wheel is Mar-M alloy and the housing is stainless steel, each rated by Garrett to 1050C (1922F), and the turbocharger has fully machined speed sensor and pressure ports.

Features

62mm compressor wheel on the G30 turbine, the largest compressor in the G30 frame
0.83 A/R internal wastegate turbine housing with V-band inlet and outlet
Assembled and calibrated by Garrett with a 0.5 bar actuator

Specifications

Compressor inducer and exducer: 62mm and 76mm
Compressor trim and A/R: 65 and 0.72
Turbine inducer and exducer: 60mm and 55mm
Turbine housing: 0.83 A/R, V-band inlet and outlet
Wastegate actuator: 0.5 bar
Maximum turbocharger speed: 145,000 rpm
Rotation: Standard

What’s Included

G30-900 turbocharger with 0.83 A/R internal wastegate housing and actuator
Oil restrictor and water fittings

Applications

The G30-900 Turbocharger is not vehicle specific. Garrett sizes it by engine and output:

Engine displacement: 2.0L to 3.5L
Power range: 550 to 900 horsepower (Garrett rating)

Notes

Garrett also builds this turbo with a 1.01 A/R housing, and sells the G30-900 super core for free-float builds
The Garrett speed sensor kit is sold separately
Garrett states that running above 145,000 rpm is at the owner’s risk and can cause damage and premature failure
Standard rotation only as a complete turbo; Garrett offers reverse rotation G30-900 parts as a super core

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.
