FJ80 manufactured from January 1990 to August 1992 powered by the 6-cylinder 4 litre 3F or 3F-E, petrol engine. The transmission a 5-speed manual or a 4-speed automatic, with a lockup torque converter. The transfer case type HF2A (full time FWD) or HF1A (part time 4WD).

Marks 4WD Adaptors manufacture kits that allow the fitting of 305 C.I., 350 C.I. early, late and LT1, and 454 C.I. engines.

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 FJ80 5-Speed Manual Kit part no. (MFK560#####) utilises the GM flywheel and clutch along with the Toyota bellhousing and sandwich plate. 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 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.

When fitting a Chevy engine 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 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. One way to identify a late model Chevy engine is by the one-piece external, rear main oil seal.

The mount and drive kit is designed to allow you to reuse the original 3F or 3FE Land Cruiser power steering pump, air conditioning compressor, alternator, and viscous coupled fan with the small block Chevy engine. All of these components have been fitted in their original positions; the power steering pump on the right hand side uses its original hoses and pulley.

The air conditioning compressor does not require re-plumbing or de-gassing, simply unbolt it from the old engine, and bolt it back onto the new brackets. Note: The Chevy engine driven fuel pump can not be used as the A/C compressor mounting bracket utilises the fuel pump mounting position on the engine block. The alternator is also removed from the old engine and bolted to the left side of the Chevy engine allowing the wiring to plug in without alteration.

The kit comes complete with a new water pump, gaskets, power steering pump brackets, air conditioner compressor brackets, alternator brackets, aluminium crankshaft pulley, fan pulley adaptor, top and bottom radiator hoses, fan belt, A/C drive belt, power steering drive belt, all bolts, washers, nuts, clamps and instructions. NOTE: This kit should only be used with the MFK1260 engine kits, the reason for this is the MFK1260 kit is approximately 2" shorter than the MFK560 kit, the shorter kit allows plenty of room for the Chevy long water pump and the Toyota Viscous coupling and fan.
