PSI Performance, 21 Exchange Drive, Pakenham (2026)

Trust is earned, and it’s something we never take for granted.

Unfortunately, John was hit with some bad news when a valve seat failure caused major engine damage in his VE SS Wagon. When it came time to put things right, he trusted the team at PSI Performance to take care of the job from start to finish.

With the Gen 4 LS V8 out of the car, we stripped it down and carried out a complete recondition from top to tail. The package included new pistons, bearings, full gasket set, comprehensive machining, precision balancing, a camshaft upgrade kit, CNC ported cylinder heads with of course new che valve seats and all the supporting modifications required to make the combination work reliably and efficiently.

We don’t believe in shortcuts. Every engine that leaves our workshop carries our name and reputation with it, so attention to detail is everything. This Gen 4 LS has been built to last and built to perform keeping budget in mind respectfully & the owners use for the vehicle.

The wagon is now back in John’s hands for the bedding-in process before returning to us for a full health check and dyno tune where we’ll dial everything in and make the most of the new combination.

One thing we’ve always stood by at PSI Performance is that we look after the people who look after us. Loyalty goes much further than money ever will. The trust and support our customers continue to show us is something we’re genuinely grateful for, and we’ll always do our best to return that loyalty through our workmanship, service, and commitment to getting the job done right.

Thank you again, John, for trusting us with the heart of your pride and joy. We can’t wait to see it back on the dyno.

Leroy’s famous VE SS — better known as “The Taxi” — is officially back… and this time it means business. 🔥

After previously coming through for extractors, OTR and a tune, Leroy decided it was time to take things to the next level with a serious bump stick upgrade. Back in the workshop, we carried out the full package with all supporting modifications and repairs completed properly — no shortcuts, no corners cut.

That’s something Leroy stands by, and so do we. We take enormous pride in our workmanship, our standards, and the reputation attached to every car that leaves our workshop. Quality work speaks for itself.

The result? This 6.0L Gen 4 LS-powered VE SS laid down an impressive 448RWHP and absolutely annihilates a set of tyres on command. A tough, well-rounded combo built to perform exactly as it should. 👌

The Taxi is back — tougher, louder and more serious than ever.

Jayden’s VE SS back on the hubs and sounding absolutely mental after receiving its fresh LSA long motor transplant paired with a VCM 825 camshaft 🔥

After fitting the new clutch kit and completing the clutch running-in procedure, it was time for the final tune and to get everything dialled in properly. While the numbers aren’t enormous right now, it’s important to remember this is a low compression engine combination built with BOOST in mind 👀 The foundation is there, the combo is tough, and once the next stage happens this thing will be a completely different animal.

For now though, it’s driving exactly how it should, sounds tough, and is ready to be enjoyed while the next plans sit on the drawing board for Jayden 💪

We also want to say a massive thank you to Jayden for the support over the years. These are the kinds of customers and relationships we genuinely appreciate — people we continue to work alongside through every stage of the build journey. It goes well beyond just business for us and that’s something we’ll never take for granted 🤝

Jamie’s Mercedes-Benz AMG C43 back in with us at PSI for another round of upgrades 🔥

This time around we fitted a brand new front grill upgrade to sharpen up the front end appearance, installed new blow off valves for that crisp response and sound, along with a fresh set of Weistec intakes — which we’re proud to now officially offer as an Australian distributor 🇦🇺

This C43 is already no stranger to PSI, with us previously carrying out our Stage 2 package including downpipes, transmission tuning, ECU & CPC tuning to completely wake this platform up the right way. The result is a car that not only performs properly but looks and sounds the part too.

At PSI we take extensive care with every vehicle that comes through our workshop. Attention to detail, correct installation procedures, cleanliness, communication and workmanship are what separate a rushed job from a PSI job.

Nothing but the best when you come in to see us 👊

Straight out of Tokyo Drift 🎌🔥

Franks insanely clean 30,000km supercharged Nissan 370Z is the definition of a dream build. The stance, the colour combo, the spec list, the presence… every single detail on this car is absolute perfection. Something you’d expect to see rolling through the streets of Fast & Furious Tokyo Drift itself.

We had the honour of getting this weapon back up to speed after it had previously been left half finished and not completed correctly elsewhere. Frank knew exactly who to call to bring this build back to the standard it deserved.

At PSI Performance we pride ourselves on what we’re known for — communication, workmanship, pride, dedication and delivering quality without cutting corners. This Z now not only looks the part, but performs exactly how it should.

Massive thank you to Frank for trusting us with such an incredible machine 🙏🏼 What a car. What a build.

Some builds mean more than horsepower figures. ❤️

Bec brought her VF SS to us with a story that hit home hard. Within just 10 months, she sadly lost both of her parents. Her father was a true car enthusiast, and working on cars together was something they both shared a genuine passion for. With an anniversary approaching, she wanted to turn this recently purchased VF SS LS3 only 3 weeks in her ownership — into something truly special in honour of those memories.

From the moment she spoke to us, there were no questions asked. She simply wanted the job done properly, and trusted us to bring her vision to life. We’re incredibly honoured she chose PSI Performance to be part of something so meaningful.

This VF received everything it deserved:
▫️ CNC Head & Cam Package
▫️ Full Manta Exhaust System
▫️ VCM OTR Bundle
▫️ Supporting components throughout
▫️ Tuned and completed with the care and attention every build should receive

The result? A genuine street monster making 351rwkw on the hubs, powered by a GM Motorsport Stealth Cam doing exactly what it was built to do. Tough, responsive and an absolute pleasure to drive.

More than anything, this build is a reminder that cars are more than machines - they hold memories, passion and connections to the people we love most.

Thank you again Bec for trusting us with something so close to your heart. We’re proud to have delivered a car worthy of the story behind it. 👏🏼

This is what happens when the combo is RIGHT and the driver behind the wheel knows exactly how to use it 😮‍💨🔥

Steph’s tough VY Calais back out there absolutely DOING GOD’S WORK at the track after the full PSI Performance treatment we built together last year 💪

Tailored to perfection from front to back with:
✔️ Head & cam package
✔️ Diff upgrade
✔️ Full exhaust system
✔️ Turbo400 conversion
✔️ Plus much, much more to handle the punishment lap after lap

And the result? A weapon that not only sounds angry but leaves HARD every single pass 👊

Massive credit to Steph as well because all the horsepower in the world means nothing without the skillset and confidence behind the steering wheel. Watching this thing get driven properly is what it’s all about! Give them a round of applause for this one 👏🔥

No shortcuts. No half jobs. Just quality workmanship, attention to detail and building cars that perform exactly how they should when it matters most.

How good is this thing!? 🔥

Happy Mother’s Day to all the beautiful mums out there ! Grandmothers, mothers , step mothers , mother figures and all those who lead with love ! Bless you all every day , not just today 🩷💐

Jimmy’s back—and he’s raised the bar again.

This stunning Mercedes-Benz AMG C63 S Coupe rolled into the shop for our full PSI Stage 2 treatment, and we didn’t hold back. Downpipes, intakes, and precision tuning—executed the right way, not the quick way.

We’re talking 544 RWHP and 974Nm of torque at the hubs. Real numbers. Real performance.

And just as important as the result is how we get there. This wasn’t a shortcut job—gearbox out, everything installed properly, all bolts handled correctly, refilled and reassembled to factory-plus standard. No cutting corners, no guesswork. That’s the difference.

Hit play and have a listen to it on the hubs… the crackles, the pops, the aggression—this thing absolutely comes alive.
Sound on.

At PSI, we don’t just build cars—we build trust. Our customers come back because they know one thing: when it’s in our hands, it’s done right. Every time. No compromises.

You want performance? That’s easy.
You want it done properly, reliably, and backed by people who actually care? That’s where we come in.
