80 Series Land Cruiser Information: HZJ80 manufactured from May 1990 to 1998 powered by the 6-cylinder 4.2ltr diesel engine. The transmission a 5-speed manual. The 4-speed automatic, with a lockup torque converter was not an option with this engine. The transfer case type HF2A (full time FWD) or HF1A (part time 4WD). 100 Series Land Cruiser Information:NOTE: late model 100 series vehicles fitted with naturally aspirated 1HZ diesels are fitted with a R151 gearbox, this gearbox we consider to be marginal in strength. If you are considering a V8 conversion it should be replaced with a gearbox from a 4.5 petrol or a turbo diesel model. |
| Australian Emission Requirements To comply with Australian emission laws the new engine must have been manufactured the same year or later than the vehicle. The engine must also have all of the emission components connected, including the catalytic converter. In this instance the engine must also be run on unleaded fuel or LPG. An older engine can be fitted providing it's run only on LPG fuel. In Australia an engineer's report is required after the conversion has been completed. Contact your local RTA office for a list of engineers. |
Chevy V8 to the Land Cruiser 5-Speed Manual |
| The HZJ80/100 Manual - GM V8 Kit part no. MFK1060##### utilises the Toyota bellhousing, instead of a replacement bellhousing, a 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 flywheel supplied in the kit accepts the original Toyota 11" clutch. The flywheel is offset to the rear to place the clutch in its original position. The flywheel has no ring gear and must be used with the original GM flex plate and ring gear. Spacers and bolts are supplied to fix the flex plate to the back of the flywheel. When ordering a Chevy kit you must make sure that the GM starter motor you intend using is the correct type. Chevy V8 engines were released with two flywheel and flex plate sizes; they where fitted with a 153 tooth ring gear or 168 tooth ring gear, as a result two starter motor offsets are available. Kits are only available for the 168 tooth ring gear. It will also be necessary to identify the year of the engine, after 1986 the engine crankshaft bolt pattern changed. The bolt pattern is smaller as is the spigot, which locates the flywheel on the crankshaft (52.4-mm). The post 1986 Chevy small block engines are also externally balanced. One way to identify a late model Chevy engine is by the one-piece external, rear main oil seal. |
Engine Mounting The engine mounting kit MFK680/CK to suit the 80 series Land Cruiser consists of engine block brackets, engine-mounting rubbers, and bolts. The original Toyota chassis brackets are welded to the chassis and must be cut off with a grinder to make room for the new brackets. The new brackets must also be welded to the chassis, if you're not a good or qualified welder, we suggest a contract welder do the job. Alternatively we now manufacture engine mounting brackets that bolt directly to the Chevy engine block and onto the original Toyota engine mounting rubbers. |

Chevy V8 to the Land Cruiser 4-speed Automatic |
| The HZJ80/100 Manual - GM V8 Kit part no. MFK1060C###A utilises the Toyota bellhousing, instead of a replacement bellhousing, a 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 transmission torque converter is coupled to the flywheel via a crankshaft adaptor. The adaptor has a special bolt pattern and spigot diameter on the transmission end with the GM crankshaft bolt pattern and spigot diameter on the engine end. This allows the new flex plate (supplied in the kit) and the Toyota torque converter to be bolted to the rear as with the old 1HZ engine. On the front of the crankshaft adaptor a flywheel is used instead of a flex plate, as there is no provision to support a flex plate when the starter motor is engaged. When ordering a Chevy kit you must make sure that the GM starter motor you intend using is the correct type. Chevy V8 engines were released with two flywheel and flex plate sizes; they where fitted with a 153 tooth ring gear or 168 tooth ring gear, as a result two starter motor offsets are available. It will also be necessary to identify the year of the engine, after 1986 the engine crankshaft, bolt pattern changed. The bolt pattern is smaller as is the spigot, which locates the flywheel on the crankshaft (52.4-mm). The post 1986 Chevy small block engines are also externally balanced.
