What does 'special order item' mean for this turbocharger?

A special order item means this turbocharger is not typically kept in stock and is ordered directly from the manufacturer upon purchase. This can result in longer delivery times compared to standard stock items.

What is the significance of the 17 cm2 turbine housing and 80mm square flange?

The 17 cm2 size indicates the volume of the turbine housing, which influences how quickly the turbo spools up and its powerband. The 80mm square flange is the mounting pattern for the exhaust manifold and downpipe, offering a strong connection point for custom setups.

What supporting modifications are typically needed when installing a turbocharger like this?

Installing a turbocharger of this size usually requires significant supporting modifications. This often includes upgrading the fuel system (injectors, pump), engine management tuning, improved exhaust systems, and enhanced cooling solutions to handle the increased power and heat.
