Coastal Diesel Solutions — Bilambil NSW
Turbo & Exhaust Upgrades — Gold Coast & Tweed
Turbocharger repairs, upgrades and performance exhaust systems for diesel 4x4s, utes and trucks across the Gold Coast and Tweed. Better breathing means more torque, cooler running and a stronger tow vehicle.
Turbo & Exhaust Upgrades done properly, the first time
The turbo is the single biggest limit on what a diesel engine can do. Get air in and out more efficiently and everything improves — torque comes on earlier, exhaust gas temperatures drop under load, and the engine stops running out of breath at the top of a long climb. We diagnose and repair failed turbos, fit upgraded units where more airflow is genuinely needed, and build exhaust systems that suit the vehicle rather than just making noise.
What's Included
Everything covered in your turbo & exhaust upgrades
Turbo Repairs and Diagnosis
Whistling, whining or a sudden loss of boost usually means the turbo, but not always. Boost leaks, split intercooler pipes, a sticking variable geometry mechanism or a faulty boost solenoid produce identical symptoms and cost a fraction to fix. We pressure test the intake system and check actuator operation before we condemn a turbo.
Where a turbo has genuinely failed, we determine why. Oil starvation, a blocked drain line, foreign object damage or carbon build-up in the VNT vanes each need a different fix, and fitting a new cartridge without addressing the cause simply buys you a second failure.
Turbo Upgrades for Towing and Touring
An upgraded turbo makes the most sense on a vehicle that works hard — towing a van up the range, carrying a full touring load, or already running a custom tune that has reached the limit of the factory compressor. A well-matched upgrade delivers more airflow at the boost the engine already runs, which means more torque and lower exhaust gas temperatures rather than just a bigger number.
Sizing matters. Too large a turbo kills low-rev response and makes the vehicle miserable around town. We select units that suit your engine, your load and your driving, then match the tune to the hardware.
Performance Exhaust Systems
A restrictive exhaust traps heat and pressure in the engine. Opening up the system with a properly sized, mandrel-bent 3-inch exhaust reduces backpressure, drops exhaust gas temperatures under load and lets a tune work as intended. On a towing vehicle the temperature benefit alone is worth the job.
We fit quality stainless and aluminised systems, repair cracked manifolds, and can pair exhaust work with an upgraded intercooler and a matched tune as a complete airflow package. All systems are fitted with emissions equipment intact.
"Great Service. Cleanest workshop I've ever seen. Mick was straight-up, no BS and really helped me sort out a long term idle hunting issue, adjusted the fuelling and now my 80series is running like a dream. I'm heading back in a few weeks for injectors and a fuel pump rebuild. Highly recommend."
— Mitchel Smith
"Mick and the team at Coastal Diesel were great to deal with. The service and installing King suspension on my Isuzu NPS truck was top notch."
— Sam Schoeller
"Was looking around for a solid while for someone to do a front swivel hub rebuild on my 80 Series Land Cruiser. Contacted a young fella named Riley and he managed to book it in for me with close to no notice and got it all done on a Thursday afternoon! Would 100% recommend Coastal Diesel Solutions to anyone in need of professional, talented, fair-priced repairs. 5 stars without a doubt! Solid work team 👏"
— Andrew Bower
"Had issues with my car going into limp mode. Been to multiple mechanics, no one could fix it. One of my mates said to go to Coastal Diesel and they didn't disappoint — they did a great job!"
— Radharaman Beresford
"Highly recommend. Fixed an ongoing problem with a power issue related to the turbo and fuel delivery. So much care in his work, very knowledgeable without the BS. I'll be trusting all future services and mechanical issues to Coastal Diesel Solutions."
— Janaka Peterson
"Put me immediately at ease when I added petrol instead of diesel to our car. Our car was back on the road within 24 hours. A genuinely nice person to deal with. Many thanks."
— Jo Porter

"The best. End of story."
— Phil Towle
"Highly recommended. Dropped everything to sort a fuel issue we had with our 4WD whilst we were on holidays 1100 km from home."
— Lindsay Wallace
"Coastal Diesel did a major service and fuel system recondition to my newly restored 75 Cruiser. It runs like a dream and safe to say after a week at Fraser Island she has been put to the test. Nice to see decent workmanship is still around. Thanks to Mick and the team, I know where I'll be spending my money. Cheers!"
— Frank Waite
"Couldn't ask for better help. Mick is a top mechanic with a great personality. Don't bother wasting your money elsewhere!"
— Aaron Fairfull
"My 2013 diesel had been sick for a long time and many non-diesel mechanics charged a lot but couldn't fix it. Mick returned my call on his Christmas holidays and made time to check my car was safe to drive until he could book it in. He's kind, honest, reliable and genuinely professional — sent photos, kept me informed, and definitely won't rip you off. Turned out to be a cracked hose and solidified soot in the pipes. Now she purrs along with no smell and dramatically better fuel economy. If you have a diesel, you need a diesel specialist — and Mick is THE diesel specialist."
— Donna Dibben
"These guys installed a new engine in my Ford Transit when no Ford dealership would help. I'm now ready to take it back for its 1000 km check-up and can't find anything to complain about. Well done boys."
— Norm Morrow
