Designed for QG-Swapped K11s

This manifold has been developed specifically around fitting a turbocharger to a QG engine installed within the Nissan Micra K11 chassis.

Unlike a generic QG turbo manifold designed around the engine's original vehicle, packaging has been considered around the much smaller K11 engine bay.

This makes it an ideal starting point for customers who have already completed their QG conversion and are ready for the next logical step.

Top-Mounted Turbo Design

The manifold positions the turbocharger in a top-mounted configuration, providing a purposeful engine bay layout while helping with access to the turbocharger and associated components.

A top-mounted arrangement can also simplify certain aspects of custom:

• Downpipe Fabrication
• External Wastegate Plumbing
• Turbo Intake Pipework
• Compressor Outlet Pipework
• Oil Feed & Return Routing

The exact layout will depend on the turbocharger and supporting components selected for the build.

3D-Printed Stainless Steel Construction

Rather than manufacturing the manifold from multiple conventional tube bends and welded sections, the main structure is produced using metal additive manufacturing.

This allows considerably greater freedom when designing both the external packaging and internal geometry of the manifold.

The CAD-designed structure allows us to consider:

• Exhaust Gas Routing
• Internal Transitions
• Collector Geometry
• Turbocharger Position
• Wastegate Position
• Engine Bay Packaging
• Surrounding Component Clearance

The result is a purpose-designed component specifically intended for the application.

T25-Style Turbo Flange

The manifold is supplied with a T25-style turbocharger mounting flange, opening up a wide selection of suitable turbocharger options.

⚠️ T25 Flange Does Not Guarantee Turbo Compatibility

The term "T25" is commonly used to describe a flange pattern across numerous turbochargers.

Having the correct flange pattern does not automatically mean every T25-flanged turbocharger will physically fit the K11 engine bay.

Turbochargers can vary considerably in:

• Compressor Housing Size
• Turbine Housing Size
• Compressor Outlet Position
• Turbine Outlet Design
• Wastegate Arrangement
• Oil & Coolant Connection Position
• Overall Physical Dimensions

Turbocharger dimensions and surrounding clearance should therefore be checked when planning the complete conversion.

40mm V-Band External Wastegate

The manifold incorporates a 40mm V-band external wastegate fitment.

An external wastegate provides dedicated control of exhaust gas bypassing the turbine and is particularly useful on modified turbocharged applications where accurate boost control is required.

The wastegate outlet can then be configured as either a recirculated arrangement or screamer pipe depending on the customer's build and intended use.

Wastegate is not included unless specifically stated.

Designed for Performance

The internal gas paths have been designed to provide smooth, controlled transitions towards the turbocharger.

Reducing unnecessary abrupt transitions can help provide a more controlled exhaust gas path compared with basic fabricated log-style designs.

Actual engine performance will depend on the complete vehicle specification, including:

• QG Engine Specification
• Turbocharger Selection
• Boost Pressure
• Wastegate Setup
• Intake System
• Intercooler System
• Exhaust System
• Fuel System
• ECU
• Engine Calibration

No specific horsepower figure is guaranteed from the manifold alone.

Supporting Components Required

This listing is for the turbo manifold itself unless additional components are specifically stated or selected.

A complete turbo conversion will require additional components which may include:

• Turbocharger
• External Wastegate
• Downpipe
• Wastegate Outlet / Screamer
• Turbo Oil Feed
• Turbo Oil Return
• Suitable Sump Return
• Intercooler
• Intercooler Pipework
• Turbo Intake & Air Filter
• Fuel Injectors
• Fuel System Upgrades
• Standalone / Suitable Engine Management
• Wideband Lambda
• Boost Control
• Custom ECU Calibration

Additional components required will depend on the specification of the individual build.

Professional Installation Required

Turbo conversions require considerably more than simply bolting a turbocharger to the engine.

Professional installation is strongly recommended.

The installer should check:

• Cylinder Head Mating Surface
• Manifold Fasteners
• Turbocharger Clearance
• Bonnet Clearance
• Radiator & Cooling System Clearance
• Oil Feed & Return Routing
• Coolant Lines where applicable
• Downpipe Alignment
• Wastegate Clearance
• Intake & Intercooler Pipework
• Wiring & Hose Clearance
• Heat Management
• Engine Movement

All clearances should be checked with consideration for movement of the engine and drivetrain under load.

Turbo & Exhaust Support

The turbocharger and downstream exhaust system must be appropriately supported.

The manifold should not be expected to carry excessive weight or leverage from an unsupported turbocharger, downpipe or exhaust system.

Incorrect support can place unnecessary stress through the manifold, cylinder head and turbocharger mounting arrangement.

Heat Management

Turbocharger systems generate considerable under-bonnet heat.

Careful consideration should be given to surrounding:

• Wiring
• Brake Components
• Coolant Hoses
• Fuel Lines
• Intake Components
• Radiator Components
• Bonnet Components
• Other Heat-Sensitive Parts

Suitable heat shielding should be incorporated into the complete installation where required.

ECU Calibration Required

DO NOT OPERATE THE ENGINE UNDER BOOST WITHOUT APPROPRIATE ECU CALIBRATION.

A turbocharged QG conversion requires suitable engine management and professional calibration for the specific engine, turbocharger, injectors, fuel system and boost pressure being used.

Incorrect fuelling or ignition timing under boost can rapidly result in severe engine damage.

12-Month Warranty*

This product is warranted to the original purchaser against defects in materials and workmanship for a period of 12 months from purchase.

Our obligation under this warranty is limited to repair or replacement, at our discretion, where inspection confirms a manufacturing or material defect.

The warranty does not cover incorrect installation, physical impact, unsupported turbocharger or exhaust loads, modification, excessive exhaust temperatures caused by engine or calibration faults, incompatible turbocharger installations, incorrect heat management or failure caused by surrounding components.

The warranty does not guarantee suitability for a particular power output, boost pressure or engine specification.
