What’s so special about Linquip?
Read below what respected ‘Others’ have to say!

$_20In the first part of our special series for all you megalomaniacs out there, we turn the starter key with the story of a bushy who reckons Toyota could’ve tried harder with the 78 Series. A lot harder…

THE OWNER of this H78 Series Toyota trayback had put less than 27,000km on the clock when he decided he had to power up. A cotton farmer from Collarenebri in NSW. He spends most of his time hauling along the great expanses of flat, straight roads that black soil district is famous for. Moree, the nearest big town, is a 140km straight-line haul and Dubbo, business centre of the district, is a good 300km away.
It’s distances like these and the need to tow big loads that saw him purchase the 4.5 EFI petrol model in the first place because they’ve got the highest gear ratios in the ‘Cruiser range and the most power. However his last vehicle had been an H75 Series that Linquip Engineering in Brisbane (now Gympie) had implanted with a 6.2-litre Chevrolet diesel. The new 78 might ride a whole lot better with its coils up front and great long rear leaf springs, but our man missed his V8 diesel pulling power.

So after another run to Linquip the near-new EFI motor was pulled in favour of a rebuilt 6.5 naturally aspirated Chevrolet diesel V8. Linquip strips their imported motors, acid bathes the blocks, machines whatever needs it, and then reassembles the motors with a precision that’s usually better than the original assembly line, thanks to an added dose of TLC.  Balancing all the components is an option, and a very worthwhile one from my experience.

Originally designed by Detroit Allison as a light truck motor, the General Motors V8 diesels have a lot going for them, especially in applications that require the ultimate in reliable power. Unlike most modern motors, they’re very basic electronically – not much more than a 12-volt wire to the fuel shut-off solenoid, and another from the oil pressure gauge. Compare that to the Toyota six’s complex electronic fuel injection and engine monitoring systems, and you can bet most country mechanics would vote V8 all the way! They’ve got hydraulic roller cam followers too, sealed for life so they never wear out camshafts. The timing chain is a double roller item, dead simple and good for the 500,000km-plus service life you’d expect from a Linquip rebuild. An 8-litre sump capacity gives the V8 a small oil pan, making the fit perfect, while the whole plot weighs about the same as the Toyota six anyway!

‘Yank Power puts grunt back into 4WDs’ “The under bonnet installation is exemplary, as neat and tidy as the original, if not more so….” “….running between 14 litres per 100km to 11.5 litres per 100km (20-24mpg).”

“Move off and listen. With a big single exhaust pipe, a standard fitting for the Linquip diesels, this things sounds very, very good.” “…its got an American thump, rather than a Japenese rattle.”


“On the north side of Brisbane there’s a company called Linquip which specialises in the replacing of your worn out diesel engine with one thats affordable, compared to the cost of a new factory engine or a rebuild, but which offers an increase in power and a massive increase in torque. These engines are Chevrolet V8 Diesels.”

“Contrary to what you may think the weight gain is not worth worrying about, in the vicinity of 10-15 kgs.”

“…the first thing I noticed was the power available and secondly, the sheer unadulterated torque. The classic V8 features of smoothness and high torque, remain with this diesel.”


“Lindsay Cullen and his company Linquip have been putting smiles on the faces of diesel devotees for some years now…”

“..a naturally aspirated Toyota 2H motor will generate around 70kw @ 3500 rpm. The 6.2 litre Chev diesel offers nearly 120kw at the same rpm. ….the 6.5 litre with turbo, horsepower figures of 190kw @ 3500 rpm are more like it.”

“Linquip is a highly professional organisation with solid family involvement. Everyone concerned cares about the quality of the finished product, as well as ongoing service.”


“….the famous US Military high mobility vehicle known as the HUMMER uses the 6.2 litre Chev Diesel engine exclusively.”

“According to Lindsay, there are two main reasons people fit V8 diesels to 4WDs. The first is the desire to upgrade an existing vehicle with an engine that provides power, economy and longevity. The second results from purely financial motives, irrespective of whether the vehicle is for business or private use.”

“Conversions done for purely financial reasons are common and include many business vehicles expected to do heavy work during their working lives.”
