Pre order / made-to-order products

If the product you have ordered is a pre order or made-to-order item, it is not subject to the 14-day right of withdrawal or return under consumer protection laws, as the product is manufactured or sourced specifically based on the customer’s individual order.

This condition applies to the following product categories:

• Suspension
• Engine Tuning
• Engine Parts
• Exhaust Systems
• Fueling
• Turbochargers/superchargers
• Drivetrain
• ECE-approved Downpipes

All of the above products are manufactured or sourced individually based on the customer’s order, and therefore cannot be returned after delivery, unless the product has a manufacturing or material defect.

In the event of such a defect, the standard liability for defects as provided by consumer protection legislation shall apply.

This turbocharger is specifically designed for Nissan Patrol vehicles fitted with the BMW M57N2 diesel engine. In this engine conversion, the limited space in the Patrol's engine bay prevents the use of the original M57N2 electrically controlled turbocharger solution (OEM 758351 / 758352).

This is why a specially designed turbocharger has been developed, with the actuator positioned higher in the structure. This solution frees up space in the engine compartment and protects the actuator more effectively from water, mud and other external stresses – especially important in demanding off-road driving.

The turbocharger is available in two different performance levels, suitable for different power targets and applications.
