The kit consists of an adaptor housing which couples the Holden engines to the original Nissan petrol or diesel bell housing. The new adaptor housing measures 72 mm in length and spaces the Holden engine away from the irregular shape of the Nissan Patrol firewall. No firewall modifications or re positioning of the original transmission is required.
An input shaft extension is supplied in the kit, the input extension shaft fits over the original gearbox input shaft. The new crankshaft spigot bearing supports the input shaft extension at the front and the gearbox input bearing at the rear so no movement is experienced. The input shaft extension converts the Nissan gearbox splines to standard GM 10T dimensions.
A standard Holden flywheel and clutch (MCK117) is used for the conversion. A flywheel cover plate, thrust bearing extension carrier, spigot bush as well as all the required bolts are supplied with the kit.
An oil pressure sender adaptor is supplied in the kit. The adaptor allows the original Nissan sender to be fitted to the Holden engine.
A water temperature adaptor is also supplied in the kit. This adaptor allows the original Nissan Temperature gauge sender to be fitted to the Holden engine.
