Converting 160’s to use different engines is fairly popular. Newer engines generally have more power and torque, better economy and greater after-market support, making them excellent replacements. Below is a collection of information relating to the conversions.
The following companies make parts to suit many different conversions.
- Dellow Automotive
- Castlemine Rod Shop (CRS)
- Marks 4wd Adaptors They used to make bellhousings, however they no longer do. These do appear on the second-hand market.
- Brunswick Diesels Brunswick supplied 6.2 and 6.5 Chev V8 Diesels have been seen in 160’s, so they likely supply a kit.
Popular Engine Options
Chev V8’s (all)
A thread about using the VN-VR Commodore V6 (aka Buick motor): http://www.patrol4x4.com/forum/nissan-patrol-mq-mk-12/v6-commodore-into-mq-30389/ PS, the VS-VZ Commodore V6 (aka Ecotec motor) could be converted in a very similar manor.
Nissan RB engines

Using old carby V8s is a popular option, as the engines are fairly cheap. A common upgrade to street based motors is the use of a Holley carb, as new models are more advanced than the factory fitted units, providing better power and economy. Holleys (and similar carbs) when used off-road have a problem with the design of the fuel bowls, as hills effect the floats which effects the fuel supply. Often the vehicles will flood and stall on even the slightest of hills. It is recommended that you consider this when choosing a V8 to use in your vehicle. There are a few different options to fuel a V8, and each have their own pros and cons.
Can mod Holleys but doesnt work very well.
Quadrajet works good, has different design for fuel supply.
Using Straight Gas/LPG
Gas is good on hills, no flood etc.
If you run out of gas, your stuffed. Plus you don’t get the same mileage.
Using Gas/LPG and Petrol
Good mileage off the petrol, then switch to gas for the hills.
More parts, more to go wrong.
Using Fuel Injection (EFI)
No flood etc.
Extra electronic components can be a problem with water crossings etc.
Can covert a carby motor to EFI
- Use after-market components
- Source the factory components
- Get a bolt on efi-carb.
Choose the motor in factory EFI form, ie the 350 Chev, 302 Ford and 304 Holdens are all available in EFI.
