Chevy V8 Diesel to FZJ80 5-speed manual Kit part no. MFK1045CD 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 1FZ, bolt pattern on the rear.

The new flywheel supplied in the kit accepts the original Toyota 12" 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.

The engine mounting kit to suit the FZJ80 series Land Cruiser consists of engine block brackets, which bolt to the original Toyota engine mount rubbers. When using this kit, no firewall modifications are required.

When fitting a Chevy diesel engine with the above engine mounts the transmission cross member mounting holes will need to be slotted to bring the engine forward by approximately 20mm. After this is done the rear drive shaft will need to be lengthened or alternately a spacer can be fitted between the transfer case output flange and the drive shaft. Marks 4WD Adaptors now manufacture a 20mm long spacer for this purpose, see part number below. In most cases the front shaft will not need to be shortened however we suggest you remove the front springs and drop the suspension onto the bump stops to make sure that the slip joint doesn't bind.

When fitting the 6.2 or 6.5 ltr diesel with this conversion kit the GM engine accessories may be used, for example the A/C compressor, power steering pump and alternator. Note: The original GM water pump with a single serpentine belt is a reverse direction pump. Alternatively the Toyota accessories could be adapted to fit the new engine.

Chevy diesel engines are usually fitted with an air cleaner that looks similar to the type fitted to Chevy petrol carburettor engines. This type of air cleaner will require modifications to allow it to be used with a snorkel. To over come this problem Marks 4WD Adaptors now manufacture a cast aluminium hat that takes the place of the GM air cleaner. The inlet takes a 3 1/2" hose and will fit directly to a late model Toyota air cleaner hose, should you have an early model air cleaner with a 3" outlet a rubber adaptor hose can be used. These parts can be purchased separately or as a complete kit.
