Choose your option:

  • Without Oil Feed Pipe – for replacements where your current pipe is in top condition
  • With Genuine Oil Feed Pipe – recommended for major turbo swaps or when your current pipe is worn or restricted

Why the oil feed pipe matters:
A clean oil feed is critical to keeping your new turbo alive. Blocked or worn pipes can starve it of oil, causing early failure. We strongly recommend the pipe option if you're unsure.

Founder's Note - From Dewald & Nicole

Even before BGT4X4 existed, the mission was about you - showing that it’s possible to build a capable 4WD without overspending, so you can spend more time enjoying the lifestyle.

Back in 2021, Dewald was sharing Pajero mods on YouTube while still at uni. Like many of you, we were either DIY-building on the driveway or going on deep dives to source gear from all corners of the internet.

The goal wasn’t to chase the cheapest option, but to find parts that actually worked, delivered real value, and didn’t leave you with buyer’s remorse. That same frustration - and the demand from other Pajero owners who wanted the gear they saw working - became the spark for BGT4X4.

Fast forward, and today you have access to a carefully built range of over 200 products, tested on our own rigs so there's no guesswork. If it's not good enough for our Pajero, it won’t end up on the site.

What really matters is the support you get along the way. From the moment you land here to months after your install, you’ve got a direct line to Dewald. This means you get straight, honest advice from someone who’s fitted the gear, tested it, and lives the same 4WD lifestyle you do.

Our purpose is simple: to give you confidence in every purchase. Quality gear, prices that make sense, and real support from people who care.

Thank you for trusting us with your build and for being part of this community. Your support means the world, and we don’t take it for granted.

See you on the tracks,
Dewald & Nicole
