BIG BOOT TD42

[blockquote cite=”” type=”center”]”Running 35psi of boost, this TD42 has been built to tackle the toughest tracks in style”[/blockquote]

• Upgraded turbo running 35psi

• 214Kw at the wheels

• Custom 4in snorkel

• Gusseted front diff housing

For many 4WDers, there’s always that itch to modify your 4WDs engine for maximum power output. Extracting big power from your pride and joy often involves expensive and complicated turbo or supercharging systems – that’s not even considering the engine mods you’ll have to do on most engines for it to be able to handle all that power. But what if we told you that if you have a TD42, you can get a massive power increase with entirely bolt on parts.

This is exactly what Korey did, the proud owner of this insane TD42 GU ute, that’s running 35psi of boost with 214kw of power at the wheels! With this much power, this GU is able to tackle nearly anything that is thrown in front of it. Read on to see what makes this GU the definition of an off-road weapon.

EXTERIOR
  • 20L water tank with electric water pump
  • 30in light bar
  • Custom tray

Front Warn winch and Tigerz11 rear winch

It’s important to note that after we shot Korey’s GU, he’schanged a couple of things such as the bull bar and rock sliders. He has also added a 120L water tank under the tray with an electric water pump. With a Warn winch mounted on the front and a Tigerz11 mounted on the rear, Korey is able to get himself out of nearly any situation he finds himself in. With winches front and rear, you know this GU has been built for serious 4WDing. The custom tray and canopy is a work of art. It protects his valuables when on the road, while the bull bar, brush bars and rock sliders protect the GU when tackling gnarly tracks – which it does often.

PUSHED TO THE LIMITS
  • d42 running 35psi of boost
  • Ufi 20g billet wheel turbo
  • 3In custom exhaust
  • Millweld 4in custom snorkel
  • Front air locker
  • Gusseted front diff housing

This TD42 has had some serious work done to it. We didn’t want to ramble on about it in a large body of text, so we decided to ask Korey himself 10 questions about the build and how he went about it.

Q: Did you run into any dramas with all the power on tap?
A: The only dramas I faced were a few blown diffs. This was rectified by an upgraded solid pinion spacer. Other than that nothing has gone wrong. I’ve since taken it from Perth to the Cape with only a broken fuel line, and that’s no fault of the engine.

Q: Why did you want to get so much power from the TD42?
A: I spent good money on the initial purchase and mods done to the Patrol, so I told myself that I wasn’t going to hold back and go all out to make my ultimate 4WD. This meant working the engine and making a reliable and powerful, go-anywhere 4WD.

Q: Why a TD42?
A: I went with a TD42 because of their reputation – they are a strong and reliable engine straight from the factory, and TD42’s offer nearly endless possibilities modifications wise. It also allowed me to bolt nearly everything directly on.

Q: What have you had to mod/replace to be able to run such high levels of boost?
A: Basically the only thing I replaced was the standard radiator and fan – it wasn’t a direct necessity but replacing them with a UFI fan and a PWR radiator means it cools significantly better and offers peace of mind on those long hauls.

Q: What advice would you give other people in regards to gaining big power from their TD42?
A: The only real advice I can give to someone wanting to gain big power from their TD42 or any engine in general is to go all the way – don’t do a half job and expect it to last. If you’re committed and willing to do a proper job, you will reap the rewards – guaranteed.

Q: Cost all up to get the engine where it is today?
A: I would have spent close to $14,000 on the engine – but it was totally worth it!

Q: Who did most of the work?
A: I did basically all of the work. I’m a boiler maker by trade so I’m pretty handy around the old 4WD. As most of the build was direct bolt on, with a bit of ingenuity there was no need to get someone else to do it. The only time it went into a shop was for the fuel pump and a dyno tune.

Q: Where does all that power come in handy?
A: It really comes in handy when towing, and the GU gets put in the sand a lot, so the extra power definitely helps there. Also, it generally makes travelling and 4WDing so much easier.

Q: Did you change anything over the course of the build?

A: Yes I did, I changed the top mount intercooler to a front mount since the shoot, replaced the standard fan and radiator with a UFI fan and PWR radiator and replaced the manifold with a custom inlet manifold.

Q: Any things you would do differently if you were to do the engine upgrades over again?
A: The first thing I’d do differently would be to put a front mount intercooler in straight up instead of the top mount. It just sucks so much more air than the top mount and is more efficient – on my recent Cape trip my mate’s top mounts were nearly 100 degrees hotter than my front mount. It actually ended up cheaper than my previous top mount, but was a lot of work. It was undoubtedly worth it in the end though.

INTERIOR & 12V
  • Dual battery system
  • Gme uhf
  • Fridge/freezer

Korey has decided to keep the interior of his GU simple – he didn’t want it cluttered with unnecessary gadgets. A trusty GME UHF takes care of communications while gauges have been installed so he can keep an eye on the big TD42. He installed an under-bonnet dual battery system to powers his fridge/freezer that is housed in the custom canopy. Also in the canopy are a couple of space cases to keep all his gear organised on trips.

SUSPENSION, WHEELS & TYRES
  • Superior Engineering links
  • 4in Dobinson coils
  • Tough Dog shocks up front, Tough Dog Big Bore in rear
  • Custom top coil seats with brace
  • Tough Dog Big Bore RTS steering damper
  • 37in Goodyear Wrangler Kevlar’s

With all the mods done to the engine, don’t think for a second that Korey has forgotten or skimped on the suspension setup – that couldn’t be further from the truth. He’s gone all out on the suspension, because why have an engine with all that power and not have a suspension setup to match? In that regard, Korey has added a Road Runner Off-road steering rod and drag link, along with a Tough Dog Big Bore RTS steering dampener for improved steering.

Up front he has Superior Engineering links with Super Flex arms and 4in Dobinson coils, backed up by Tough Dog shocks. In the rear is a similar setup, adding custom upper and Superior Engineering lower locating links, and coil retainers. It also consists of Tough Dog Big Bore shocks, custom top coil seats with a brace and a Superior Engineering panard rod. This suspension setup allows Korey to tackle those gnarly tracks with ease, all while being confident it’s up to the task.
