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.

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. NOTE: Firewall modification will be required with this kit.

The engine mounting kit to suit the HZJ7# 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.

Marks 4WD Adaptors manufacture an interface-wiring loom for Holden EFI V8 engines to fit any model Land Cruiser. The loom comes with the GM plugs, all relays, and fuses mounted in waterproof holders, and instructions.

Marks 4WD Adaptors also manufacture an inline speed sensor. The speed sensor is screwed into the transfer case in place of the speedometer cable, which screws into the back of the new sensor. The signal from the sensor is sent to an interface box, which then processes the signal prior to sending it on to the ECM. The speed sensor comes with the sender, an interface box, with an interconnecting loom, which has a waterproof plug located near the sender. A small loom is also provided to allow the interface box to be connected to the ECM, ignition B+ and earth.

Commodore VT engine management computers require a stream of data to be sent to them from the body control module, prior to starting the engine. This is part of the vehicles anti theft system. The stream of data required by the PCM is special. Fortunately the input to the PCM can be switched off by changing the program information in the mem-cal. Marks 4WD Adaptors can supply mem-cals on an exchange or out right basis.

Marks 4WD Adaptors also manufacture a range of brackets to make the EFI parts easy to install, they are the high pressure fuel pump and damper bracket, relay mounting bracket, high pressure fuel filter bracket, carbon canister bracket, map sensor bracket and mounting bolts, nuts and clamps.

The HZJ7# will require a high-pressure fuel pump and filter system when fitting the EFI Holden V8 engine. Marks 4WD Adaptors now have a kit that includes a high pressure, fuel pump, and filter along with all of the other EFI component mounting brackets required to do the job.

No kit is available to fit the Holden Trimatic bolt pattern, as this bolt pattern can not be machined into the adaptor. When ordering Holden 308 V8 kits, please make sure the bolt pattern at the rear of the engine is a Turbo (Chevy) pattern.

Holden V8 engines are available with two bellhousing bolt patterns all 253 C.I. engines have the Holden Trimatic bolt pattern.

The 308 C.I. engines are available with the Turbo or Trimatic bolt patterns.

The 1988 VN and later 304 C.I. and 350 C.I. engines have the Turbo bolt pattern.

The bolt patterns are illustrated below.
