Pimp My Ride: Hilux Edition 🛻💨 | Episode 3 Exhaust Upgrade 🔥

Time to let this Hilux breathe!

We’ve ditched the restrictive factory exhaust for a Manta 3” DPF-Back Stainless Steel Exhaust, giving our N90 Hilux the flow, performance and sound it deserves.

Here’s why this upgrade makes a difference 👇

✅ 3” mandrel-bent piping for improved exhaust flow
✅ Reduced exhaust back pressure to help lower EGTs
✅ Improved throttle response and towing performance
✅ Pairs perfectly with one of our tunes to unlock even more gains
✅ Quality stainless steel construction built for Aussie conditions
✅ A deeper, tougher exhaust note without the highway drone

Built for the work, ready for the weekend 🛠️🏕️

Follow along as we continue building the ultimate Hilux setup, combining practical upgrades, performance and a bit of attitude.

Work hard. Play harder.

Pimp My Ride: HiLux Edition 🛻💨 | EP. 2

Next up in the ultimate all-rounder N90 Hilux build… the airbox 🔧

One thing we see far too often through the workshop? Hilux and LandCruisers with airboxes that aren’t sealing properly.

And on a diesel, that can be a BIG problem.

Fine dust getting past the filter can work its way into the intake and start dusting the engine, wearing turbo components, cylinder walls and rings. The scary part? You might not know it’s happening until the damage is already done.

So on our own rig, we’re not taking the chance.

We’ve upgraded the factory setup to a Donaldson PowerCore air intake, giving us:

💨 A purpose-built positive seal to keep unfiltered air out
💨 Donaldson Filtration Australia PowerCore filtration technology designed for serious dust loading
💨 Higher dust-holding capacity = longer service intervals
💨 30% increase in airflow
💨 More confidence on long, dusty trips

If we’re putting it on our own Hilux you know we rate it👌

If your Hilux or LandCruiser spends time on gravel roads, tracks or dusty conditions, it’s worth getting your airbox and intake checked.

When it comes to diesel engines, dust is the silent killer.

Pimp My Ride: Hilux Edition 🛻💨

We’ve driven our 2026 N90 Toyota Hilux straight out of the showroom and into the workshop. Now, join us as we transform it into the ultimate all-rounder, built to work hard during the week and play hard on the weekend, while improving performance, reliability and longevity.

Welcome to Episode One 👇

First up, we’re custom fitting an HPD oil catch can. Why, you might ask?

Modern diesels recirculate crankcase gases back into the intake. Along with those gases comes oil mist, which mixes with soot from the EGR and can build up as thick sludge in your intake manifold and on your valves.

Over time, that buildup can restrict airflow, impact performance and fuel economy, and lead to a costly intake clean down the track.

An HPD catch can traps that oil mist before it makes its way into your intake, helping keep things cleaner and protecting the system long term.

🔧 Cleaner intake & reduced carbon buildup
🔧 Consistent performance & economy
🔧 Better protection for your intercooler & turbo system
🔧 Less chance of expensive intake clean-outs down the track

This one of the easiest modifications you can make to your diesel which will pay dividends over the lifespan of the engine.

And this is just the beginning…next up air box upgrade 👀

⚠️ FORD 2.0L ECOBLUE OWNERS, READ THIS BEFORE IT’S TOO LATE ⚠️

If you’re driving a Ford Ranger or Transit with the 2.0L EcoBlue or BiTurbo engine, there’s a problem hiding behind your timing cover and in your oil pan that most owners don’t find out about until it’s too late: the wet timing belt.

Unlike a traditional cam belt that runs dry in its own housing, the EcoBlue’s timing belt sits fully submerged in engine oil. Over time the belt material breaks down, softening, swelling, and shedding rubber debris straight into your oil.

That debris clogs the oil pickup strainer, starves the engine of oil pressure, and the result is bent valves, smashed pistons, and in the worst cases a completely destroyed engine.

It’s such a widespread issue that Ford has already wound back the recommended replacement interval, and plenty of workshops are seeing belts fail well before that. By the time the warning light comes on, the damage is usually already done.

🔧 At Jmac Performance & Diesel, we’ve got the specialised gear and the know-how to properly inspect and replace these belts, catching the problem before it turns into a multi-thousand-dollar engine rebuild.

If your 2.0L EcoBlue Ranger or Transit has ticked over 100,000km and the wet belt hasn’t been done yet, don’t wait for it to fail. Get in touch with us and we’ll sort it.

Big day on the tools down at Rivers Edge, Docklands ⚓️

Full major service on twin MerCruiser 496 MAG engines, all filters, spark plugs, and fluids replaced to keep this 40ft Riviera running at its best.

Also gave the Onan gen-set (generator) the attention it needed, including replacing the salt water filter and housing after a cracked, perished top cover.

Two major services in one hit… just another day in the office 👊
