PSI Performance

Here’s another version of one of the most rewarding builds we’ve had through PSI. 💚

Adrian’s Mk1 Es**rt was a massive transformation from where it started — yellow paint, carburettors, RS-style wheels and factory trim — to the finished car you see here today.

Nearly 12 months of work, plenty of problem solving, fabrication, changes along the way and a fair few “while we’re here…” moments 😂 but the end result made every bit of it worthwhile.

A huge thank you again to everyone who played a part in bringing this car together:










And a special thank you to Cherie from for the editing skills on this reel and for helping us capture this build properly. 🙌 You’ve absolutely nailed it.

Building this Es**rt for my cousin made the whole project that little bit more special. One hell of a transformation, one hell of a journey, and definitely a build we’re proud to have our name on. 💚🏁

“Just a head and cam package,” they said… 😂

Josh brought his Impulse Blue VZ SS Ute into PSI for what should have been a relatively straightforward upgrade. What followed was the automotive equivalent of opening a can of worms—only to discover the worms had ordered more worms.

The final package included CNC-ported heads, a VCM 825 camshaft, CHE trunnions, upgraded timing chain and oil pump, ARP bolts, rear main seal, clutch kit, starter motor, fuel pump, crank and cam sensors, OTR intake, exhaust system, plus a Truetrac and gear upgrade for the diff.

You name it—we probably repaired, replaced or upgraded it.

Then there was the “healthy little LS1” with no identification tags… which somehow required 6.0-litre cam bearings. 🤭🤐 The little engine that could certainly kept us guessing!

After more than two months, several serious hurdles and enough plot twists to fill an entire Netflix series, we refused to let this one beat us. With Josh’s patience and understanding—and our determination to see the job through—we finally got this VZ exactly where it needed to be.

The result was a stout 423.9 HP and 506.7 Nm at the hubs, with peak power recorded at 6,532 RPM. A brilliant result for the mysterious little LS1 that fought us nearly every step of the way!

Some builds test every bit of your knowledge, patience and persistence—but they’re also the ones that make the finished result feel even better.

Thank you, Josh, for trusting us, remaining patient and giving us the opportunity to finish the job properly. This Impulse Blue beast put up one hell of a fight—but PSI got the final word. 💪🏿

350,000+ KMS AND STILL NOT READY TO RETIRE 💪🏿🔥

Manlito is back at PSI Performance with his VF Calais — this time with a lifter noise that unfortunately had caused a little more damage than we first expected. 😅

The positive side?

Upgrade time. 💪🏿

Once we got into it, we addressed everything that needed attention while we were there and upgraded the right components along the way:

• New LS7 lifters
• New oil pump
• New VCM camshaft
• New cam bearings
• New sump gasket
• New CHE trunnions
• New heavy-duty pushrods
• New ARP crank bolt
• New water pump gaskets
• New timing cover gasket
• New front crank seal
• New engine mounts
• New water pump
• New… well, you get the idea. 😂

At 350,000+ kilometres, this L77 has certainly done some work. This wasn’t a full engine recondition, but while it was apart we made sure the affected areas were properly repaired, the necessary components were replaced and the supporting hardware was upgraded to give it the best chance at plenty more life.

The combo itself stays simple and proven — cam, OTR and exhaust — and for a high-kilometre L77, it’s still producing very respectable power and driving exactly how it should.

That’s what we’re about at PSI Performance. Find the problem, fix what actually needs fixing, upgrade where it makes sense and get the car back out there doing what it was built to do.

No unnecessary fluff. No pretending it’s something it isn’t.
Just the right repair, the right parts and getting it done properly. 🔧🔥

Thanks again for the continued support, Manlito. Now let’s see how far past 350,000 km this thing wants to go. 😂

BUILT AT HOME. FINISHED ON THE HUBS. 🔥

Bradley’s VF Maloo came back to PSI Performance after a serious transformation — upgraded and repaired at the same time, with the factory LS3 making way for a tough 416ci combination built to handle business.

The new combo features Dart sleeves, a Turbo Killer camshaft, Blackwell CNC heads, CHE trunnions and just about all the extra fruit you can think of. 💪

The best part? Brad took the short motor and turned it into a complete long motor himself, then removed and refitted the whole package back into the Maloo. That’s a massive effort in itself.

We also set him up with an upgraded Truetrac 3.9 diff, along with a new high-stall converter properly matched to the engine and cam combination.

Brad then did everything the right way — ran the engine and diff in, completed his fluid changes, flushes and checks, then brought it back to PSI Performance for the final piece of the puzzle: onto the Mainline hubs to get the calibration dialled in and the whole package working together properly.

What a successful self-built mission. 👏

Bradley has been an absolute gentleman to deal with, along with his father Frank and the whole family. Jobs like this are a privilege for us because we get to help finish off something the owner has poured so much of their own time and effort into.

10 stars, Brad. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
Thank you for trusting PSI Performance with the diff, converter and tuning side of the build. We genuinely appreciate the opportunity and can’t wait to see this Maloo get put to work! 🚀

Some builds are just jobs… this one became a journey. 💚

This Mk1 Es**rt rolled into PSI wearing yellow paint, carburettors, RS-style wheels and factory trim. Nearly 12 months later, it’s been completely transformed into the car Adrian always envisioned.

The list is massive:
✔️ Full strip and repaint by the boys at
✔️ UK Image Wheels with a shortened diff and axles to suit
✔️ Custom caster arm conversion and front track adjustment.
✔️Coil over upgrade
✔️ Four-wheel disc brake upgrade
✔️ New seats and door trims.
✔️ FuelTech EFI conversion with an EFI Hardware ITB setup.
✔️Windows tinted by Paul from dark side of the film
✔️ Electronic fuel system, shortened steering rack, upgraded clutch, phased distributor, front guard clearancing for steering sweep… and finally onto the hubs where, with some help from the legend N**s at FuelTech, we dialled it in exactly as it should be.

That’s only part of the story…

This build pushed us, tested us and reminded us that doing things properly takes time. There were plenty of moments where we loved it… and plenty where we wanted to push it into the corner! 😂 But seeing the finished product makes every late night and challenge worthwhile.

Building this for my cousin made it even more special. It was a privilege from start to finish, and I’d do it all again tomorrow.

A huge thank you to everyone who had a hand in bringing this Es**rt to life. If I’ve missed your name, please know your contribution didn’t go unnoticed.

And a special thanks to Cherie from Uncanny Media for jumping in last minute to capture these shots and help us put together this reel.

This is just the start… we’ve got plenty more photos of the transformation coming soon. Stay tuned. 👌

🚨 Proof that performance addiction is a real thing… once you’ve had one PSI build, there’s no going back. 😏

A huge welcome back to our good friend and loyal customer, Eddy, who’s no stranger to the PSI family. Last year we transformed his stealthy black C5 Corvette with an extensive package including a head & cam upgrade, gearbox, converter, custom clutch, OTR, mechanical repairs and a complete custom dyno calibration. The result? An absolute weapon.

Now he’s back… but this time with the newest addition to the fleet—his N Series Hyundai i30. 🔥

We treated the i30 to our Stage 2 Package, featuring a high-flow intake pod upgrade and a complete turbo-back exhaust system fitted with Varex remote-controlled rear mufflers. The best part? You still retain full factory functionality across all drive modes while enjoying a completely different driving experience.

✅ More power.
✅ More torque.
✅ Better throttle response.
✅ A deeper, more aggressive soundtrack when you want it.
✅ Noticeably improved fuel efficiency that’ll even make you smile when you’re standing at the bowser.

The fleet has definitely levelled up… from an all-black Corvette to a black-and-red combo that absolutely nails the look. Now the only challenge is keeping that little rocket pointing in the same direction every time the boost comes on… and resisting the temptation to turn every set of traffic lights into a qualifying lap. 😂

Congratulations, Eddy! We genuinely appreciate your continued trust and support. It’s relationships like these that make what we do so rewarding. Enjoy the new setup, mate—we can’t wait to see what’s next.

Every expert was once a beginner… and every car enthusiast has a first chapter. Welcome to yours, Armani. 👋🏁

It’s always exciting seeing someone take their first steps into the automotive and motorsport world, and we’re proud to be part of that journey.

Armani brought her Holden SV6 into PSI Performance to lay down the right foundations. Fitted with a VCM OTR and exhaust package, it was time to go over the car properly, run the spanners over it, complete a few mechanical upgrades, and finish it the right way—on the hub dyno, where we could dial in the power, drivability and efficiency as one complete package.

Anyone can bolt parts onto a car. The difference is making sure they all work together reliably, safely and exactly as they should.

At PSI Performance, it’s about more than chasing horsepower. It’s about building confidence, creating friendships, sharing knowledge, and helping people enjoy every moment behind the wheel—whether it’s their first modified car or their fiftieth.

Welcome to the PSI family, Armani. We can’t wait to watch your passion for cars continue to grow, and we’re honoured you’ve trusted us to be part of the journey. Here’s to many more upgrades, plenty of smiles, and a whole lot of memories ahead. 🙌🔥

Some customers become mates… and some mates become family. Emre falls into that category. 🍻

Our returning legend rolled his VZ Clubsport back through the doors for what started as a simple OTR upgrade, service and inspection… and, well… let’s just say the inspection had other ideas. 😂

This time around we knocked over:
✔️ Upgraded OTR
✔️ Full service & inspection
✔️ Rear link pin bushes
✔️ Rear subframe bushes
✔️ Rear diff mount bush
✔️ Fuel filter
✔️ Tailshaft donuts
✔️ Extension housing seal
✔️ Rear diff oil
✔️ Gearbox oil
✔️ Brand new power steering rack & lines
✔️ Fresh power steering fluid
✔️ New lower control arms

…and that’s just the base package! 😅

The best part? This VZ now drives the way an HSV should. Tight, responsive, reliable and ready to cop whatever Emre throws at it.

Then it was time to bolt it onto the hubs and send it to the dyno gods. 🔥

And that soundtrack… an LS2 breathing through a VCM 710 cam and a 2.5-inch exhaust. It’s the sort of noise that makes small children smile, grown adults cry, and your neighbour suddenly become a mechanical engineer. 🤣

After all that work, the only thing this thing needs now is… more traction! Good luck with that, Emre. 😏

Thanks again for the continued trust and support, mate. We never take it for granted, and it’s always a pleasure looking after the people who look after us.
