Quick Overview

BorgWarner EFR Turbo - 179392 (EFR-7670) - 1.05 A/R - T4 Turbine Inlet Flange - Twin Scroll Non-WG


BorgWarner EFR 179392 are retrofit turbochargers developed with some of the latest turbocharger technology.

EFR Turbos Feature:
• Gamma-Ti turbine wheel
• Dual ceramic ball bearing assembly with metal cage
• Forged milled extended tip compressor wheel
• Stainless steel turbine housing
• Water cooled bearing housing
• Large internal wastegate
• Compressor recirculation valve (a.k.a BOV)
• Boost control solenoid valve
• Standard T4 mounting flange

Low Inertia Turbine Wheel
Gamma-Ti turbine wheel cuts turbine inertia by roughly 50% dramatically improving turbo response. Turbine sizes range from 55 to 80mm in exducer diameter.

Heat Resistant Turbine Housings
Investment cast stainless steel turbine housings improve durability and offer an offer extremely smooth internal flow channel. Turbine housings have thin walls to reduce weight and thermal inertia.

High Turbine Efficiency
Superback and Fullback back-disk shapes offer very high efficiencies. The Superback shape adds a curved profile to the back-disk and has the effect of lowering centrifugal stress and permitting higher rotational speeds.

Enhanced Turbo Response
EFR turbochargers use a dual-row ball bearing cartridge with ceramic balls and metal cage. This bearing system provides substantial friction reduction at low turbo speeds and in the process helps improve turbo response. Metal cage improved the durability of the ball bearing assembly.

Flexible Compressor Cover
The EFR turbo large cover has a dual-machined outlet, both for a hose connection and a v-band connection.

Simplified Installation
Integrated compressor recirculation valve (CRV) to help avoid compressor surge and backflow during a throttle lift event. This feature helps to simplify the installation task and lowers overall system install cost.

Forged Milled Compressor Wheels (FMW)
EFR turbos contain wheels that are fully milled from forged aluminum, commonly known as billet. Cut from custom forgings, their strength exceeds that which is available from typical bar-stock and also exceeds the material properties of an aluminum casting.

Sensor Mounting Convenience
Speed sensor mounting provisions are also supplied on every compressor cover. Speed sensors are sold separately.

Boost Control Solenoid Valve (BCSV)
A boost control solenoid valve (BCSV) is included with every EFR turbo.

High Flow Wastegates
Purpose designed large wastegate ports give the wastegated EFR turbos the capability of handling the flow requirements of high performance applications.

Ease of Orientation
Turbo orientation flexibility is facilitated by the wastegate bracket to bearing housing mounting arrangement.

Adjustable Wastegate
The fabrication and installation task is simplified with wastegated EFR models that feature adjustable wastegates available in three different canister sizes.

Not included with turbo assemblies:
• Speed sensor
• Turbine outlet V-Band
• Turbine inlet gasket
• Oil drain gasket or drain port fitting

Super Core Configuration
The following parts are not included as part of the super-core assembly: turbine housing, assembly clamp plate hardware, wastegate parts.

Turbine Housing Options

BorgWarner EFR 179392 Turbine Housing Options

BorgWarner EFR turbochargers come with an integrated oil restrictor built in to the turbos. On the vast majority of applications this is adequate to control the amount of oil entering the turbocharger.

All BorgWarner EFR turbos are designed to be run with water cooling to the bearing housings (this is particularly important on units fitted with the aluminium bearing housings). Failure to run this system could lead to the premature failure of the turbocharger. The turbo features 4 water ports of which only 2 are required (the other 2 ports can be blocked off). Ensure water enters the bearing housing through a bottom port and exits through a top port.
