Bell Housing Adaptor Kit – Holden V8 (Turbo Pattern) to Toyota LandCruiser 4.2L 1HZ (5-speed)
This kit comprises of a flywheel housing running a 3 piece steel flywheel.
The flywheel housing is supplied which measures 61 mm/2.4″ long. This housing has the GM bolt pattern on the front and the Toyota 1HZ, bolt pattern on the rear.
The new steel flywheel is the same design as the one used with the LS series engine kits. It is supplied with a flex plate stiffener which bolts up to the original GM flex plate, the stiffener is basically a very thin flywheel. A crankshaft adaptor/spacer is bolted to the crankshaft which also secures the flex plate/ring gear and flex plate stiffener to the crankshaft. The original GM/Holden flex plate with the 153-tooth ring gear is used. The new steel flywheel is drilled and doweled to accept the standard LandCruiser 4.2Lt 1HZ 11″ clutch as fitted to HZJ## series engines.
The flywheel assembly is heavier than a standard flywheel, 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.
