Garrett GBC Turbocharger Options

At the heart of the package is the Garrett GBC turbocharger range.

Three turbocharger options are available, allowing the system to be configured around the intended engine specification and performance target.

The correct turbo isn't simply the biggest one available.

Turbocharger selection affects:

• Boost Response
• Power Delivery
• Usable RPM Range
• Maximum Airflow Potential
• Exhaust Backpressure
• Engine Character
• Ultimate Power Potential

A smaller turbocharger can provide a particularly responsive setup on a smaller-capacity CG engine, while larger options provide additional airflow headroom for customers pursuing greater power.

The correct choice depends on engine capacity, intended boost pressure, RPM range, fuel, ECU calibration and intended use.

3D-Printed Stainless Steel Top-Mount Manifold

The kit features our purpose-designed 3D-printed stainless steel top-mount turbo manifold.

Additive manufacturing gives us considerably greater freedom over the internal geometry than would be available with a basic fabricated log manifold, allowing the runners and transitions to be designed specifically around the packaging constraints of the K11 engine bay.

The top-mount arrangement also provides a purposeful installation while positioning the turbocharger for the rest of the system to be packaged around it.

Why 3D Print the Manifold?

3D printing allows complex shapes and transitions to be incorporated directly into the manifold design without being restricted entirely by conventional tube bends and fabricated joints.

This allows us to optimise the component around:

• Exhaust Gas Routing
• Turbocharger Position
• Wastegate Position
• Engine Bay Clearance
• Compact Packaging
• Internal Transitions

The result is a manifold specifically designed as part of the complete turbo system rather than a generic component adapted to fit.

Turbosmart External Wastegate

Boost control is handled by a Turbosmart external wastegate.

External wastegate control provides a dedicated path for bypassing exhaust gas around the turbine when the required boost level is reached.

Correct wastegate control is essential for maintaining stable and predictable boost pressure.

Wastegate Outlet Options

Choose between:

Screamer Pipe

or

Recirculated Wastegate Outlet

Screamer Pipe

The screamer configuration vents the wastegate outlet separately from the main exhaust.

This provides a simple, unrestricted wastegate discharge arrangement but is extremely loud when the wastegate opens.

Primarily suited to motorsport and competition applications.

Recirculated

The recirculated configuration routes the wastegate discharge back into the exhaust system.

This provides a considerably more civilised arrangement for vehicles where noise is a consideration.

2.5" Downpipe & Link Pipe

The kit includes a purpose-built 2.5" downpipe and link pipe, incorporating a 3D-printed high-flow transition/flange arrangement at the turbocharger.

The larger exhaust path helps minimise unnecessary restriction downstream of the turbine while providing the connection into the remainder of the vehicle's exhaust system.

The downstream exhaust system must be suitably sized and supported for the intended engine output.

Front-Mount Intercooler

Included within the package is a substantial front-mounted intercooler measuring approximately:

550mm x 230mm x 65mm

Compressing air through a turbocharger increases its temperature.

The intercooler's job is to remove a proportion of that heat before the compressed air enters the engine, increasing charge-air density and helping provide more stable intake temperatures.

This becomes increasingly important as boost pressure and sustained engine load increase.

3D-Printed Intercooler End Tanks

Rather than relying purely on conventional fabricated sheet-metal end tanks, the intercooler incorporates 3D-printed end tanks developed around the installation.

This manufacturing method allows greater control over the shape of the transition between the intercooler pipework and core.

Fully Welded Intercooler Pipework

The package includes purpose-built fully welded intercooler pipework.

Reducing the number of unnecessary silicone joints and connections provides a cleaner installation with fewer potential connection points within the charge-air system.

Silicone connections and clamps are used where required for installation and drivetrain movement.

Turbo Intake & Air Filter

A purpose-built turbo intake and performance air filter are included to complete the turbocharger inlet arrangement.

Correct intake sizing and routing are important for allowing the compressor to operate efficiently without unnecessary inlet restriction.

New Sump with AN10 Turbo Oil Return

Correct turbocharger oil drainage is critical.

The kit therefore includes a new engine sump fitted with an AN10 turbo oil return connection.

This provides a dedicated return path for oil leaving the turbocharger and removes the need for the customer to modify their existing sump during installation.

The oil return must still be routed correctly, with a suitable continuous gravity-assisted path from the turbocharger to the sump.

Restrictions, kinks or unsuitable routing can result in turbocharger oil drainage problems.

Manifold Stud & Nut Kit

A complete replacement manifold stud and nut set is also included.

Considering the age of most K11s, we don't believe it makes much sense to build a complete new turbo system and then rely on decades-old, potentially corroded exhaust manifold hardware.

What's Included?

The core GBC Turbo Kit includes:

• Garrett GBC Turbocharger
• 3D-Printed Stainless Steel Top-Mount Turbo Manifold
• Turbosmart External Wastegate
• 2.5" Downpipe
• 2.5" Link Pipe
• Selected Screamer or Recirculated Wastegate Outlet
• 550 x 230 x 65mm Front-Mount Intercooler
• 3D-Printed Intercooler End Tanks
• Fully Welded Intercooler Pipework

⚠️ IMPORTANT - ECU, INJECTORS & MAPPING

A turbo kit alone is not everything required to safely turbocharge an engine.

Unless specifically selected or stated as part of your order, the package does NOT include:

• Standalone ECU
• ECU Wiring / Adapter
• Fuel Injectors
• Fuel Pump
• Wideband Lambda System
• Boost Control Solenoid
• ECU Calibration / Mapping
• Clutch Upgrade
• Engine Internals
• Exhaust System beyond the supplied kit components

The vehicle must have suitable fuel delivery and engine management before being operated under boost.

Do not install the turbo kit and attempt to drive the vehicle under boost using an unsuitable factory ECU calibration.

Incorrect fuelling, ignition timing or boost control can destroy an engine extremely quickly.

How Much Power Will It Make?

There is no single horsepower figure that can accurately be quoted for every K11 fitted with this package.

Potential output depends on:

• CG10DE, CG13DE or CGA3DE Engine
• Engine Condition
• Compression Ratio
• Turbocharger Selection
• Boost Pressure
• Fuel Type
• Injector Size
• Fuel System
• Exhaust System
• Intake System
• ECU
• Calibration
• Internal Engine Specification

The package provides the hardware foundation for the turbo conversion. The final power level must be chosen according to the engine specification and supported with appropriate fuelling, management and calibration.

More Boost Doesn't Automatically Mean Better

Particularly on a standard internal engine, the objective should be to produce a responsive and reliable package rather than simply chasing the largest possible dyno number.

Cylinder pressure, charge temperature, detonation control and ECU calibration become increasingly important as output rises.

Engine Condition Matters

Before turbocharging any K11, particularly an original high-mileage engine, we strongly recommend checking its mechanical condition.

This can include:

• Compression Test
• Leak-Down Test
• Cooling System Condition
• Oil Pressure
• Timing Chain Condition
• Head Gasket Condition
• Spark Plugs
• Ignition System
• Fuel System

A turbocharger will not fix an unhealthy engine. Increasing cylinder pressure will generally expose existing problems much more quickly.

Supporting Modifications

Depending on the intended power level and use, additional upgrades may include:

• Standalone Engine Management
• Larger Fuel Injectors
• Upgraded Fuel Pump
• Performance Clutch
• Improved Cooling System
• Suitable Exhaust System
• Engine Mount Upgrades
• Limited-Slip Differential
• Brake Upgrades
• Appropriate Tyres
• Internal Engine Upgrades

The requirements for a responsive low-boost road car can be very different from those of a high-output competition build.

Professional Installation & ECU Calibration Required

This is a substantial performance modification and should be installed by somebody experienced with turbocharged engine systems.

Before operation, the complete installation must be checked for:

• Oil Leaks
• Coolant Leaks
• Fuel Leaks
• Exhaust Leaks
• Boost Leaks
• Oil Feed & Return Routing
• Intercooler Pipe Clearance
• Turbocharger Clearance
• Exhaust Clearance
• Wastegate Operation
• Fuel Pressure
• Correct Sensor Operation
• Correct ECU Configuration

The vehicle must then be professionally calibrated for the completed engine specification.

Motorsport / Off-Road Use

This product substantially modifies the vehicle's engine, intake and exhaust systems.

Depending on specification, the conversion may affect emissions compliance, exhaust noise, insurance, vehicle approval and road legality.

It is intended primarily for motorsport, competition and off-road applications, and the purchaser is responsible for ensuring compliance with regulations applicable to their vehicle and jurisdiction.
