In Australia an engineer's report is required after the conversion has been completed. Contact your local RTA office for a list of engineers.

We recommend fitting front disc brakes to all vehicles being fitted with V8 engines. Most engineers in Australia will not engineer your vehicle without them. Toyota Hilux front discs, hubs and swivel housings can be fitted.

The GM V8 to FJ kit part no. (MFK371#####) utilises the Land Cruiser 11" clutch set up on a new flywheel along with a new bellhousing that measures 240mm/9.45" in length. This new bellhousing and flywheel has been designed to move the engine forward giving adequate clearance between the cylinder heads and firewall. Re positioning of the transmission or firewall modifications are not required with this kit.

Internally balanced GM engines used with the following kits: MFK371C, and MFK371C/5

This new flywheel is fully balanced and fitted with a new GM 153-tooth ring gear, it is drilled and doweled to accept the standard Land Cruiser 11" clutch as fitted to the 2F engines. The flywheel is heavier, giving greater inertia allowing the engine to idle smoother. The extra weight also helps to give less chance of stalling the engine when off road climbing over rocks, and taking off on steep inclines. The extra weight of the flywheel has no adverse effect on the engine.

As the flywheel supplied with the kit has a 153-tooth ring gear you must use the correct Chevy starter motor to suit. This starter motor can be identified as having an alloy nose cone and uses a short and long bolt to attach the starter to the engine block.

Externally balanced GM engines used with the following kits: MFK371CE and MFK371C/L4.

This new flywheel is fully balanced, and is drilled and doweled to accept the standard Land Cruiser 11" clutch as fitted to the 2F engines. The flywheel is heavier, giving greater inertia allowing the engine to idle smoother. The extra weight also helps to give less chance of stalling the engine when off road climbing over rocks, and taking off on steep inclines. The extra weight of the flywheel has no adverse effect on the engine.

This new flywheel does not have a ring gear fitted, it bolts to the crankshaft behind the GM flex plate. The flex plate carries the ring gear and the balance weight for the engine. The flex plate ring gear must have 168 teeth. The flex plate is secured to the back of the flywheel with 6 bolts and spacers.

The bellhousing accepts all the Land Cruiser 2F 6 cylinder petrol components such as the bellhousing mounts, slave cylinder, clutch fork etc.

It will also be necessary to identify the year of your Chevy engine, particularly the late model engines as the crankshaft bolt pattern changed in 1986. The post 1986 Chevy small block engines were also externally balanced. One way to identify a late model Chevy engine is by the one piece, external rear main oil seal.

Chevy V8 to FJ40, FJ45, and FJ55 4 and 5-Speed Manual Kit part no. (MFK560#####) utilises the GM flywheel and clutch along with the Toyota bellhousing. Instead of a new bellhousing, a flywheel housing is supplied which measures 122 mm/4.8" long. This housing has the GM bolt pattern on the front and the Toyota 1F, 2F, and 3F, bolt pattern on the rear.

The kit has been designed to allow for firewall clearance without shifting the transmission or altering the drive shaft lengths.

The gear box input shaft is coupled to the clutch via an input extension shaft. The shaft has the Toyota internal spline and spigot diameter on the gearbox end with the GM external spline and spigot diameter on the engine end. The front of the shaft is supported in the crankshaft by a sealed ball bearing inside an adaptor ring.

The clutch is operated through a thrust bearing extension sleeve, which is supported in a machined boss located in the centre of the housing. On the front of the sleeve is a bearing to suit the GM clutch pressure plate.

Engine mounting kits consist of replacement chassis brackets which can be bolted or welded to the chassis rails and utilise GM engine mounting rubbers. These rubbers have been found to be stronger than the Land Cruiser rubbers.

The engine mounting kits have been designed to give you sufficient legal engine sump to differential clearance when used with a standard rear bowel GM sump.

Two types of engine mounting rubbers are available, standard Chevy type and now a heavy duty rebuildable type using urethane bushes. Click here for details.
