As we are racing towards the weekend, we have loads going through the workshop. Tail shafts in steel, chromoly and carbon have been flying out the door. Engines are being completed and going back in cars, while new ones are coming out to be given the JOH/Dully special treatment. Come down and see us or give us a cal 07 3282 2194 to discuss your requirements for tail shafts, machining, rebuilding, dyno servicing and custom CNC.

This week's workshop job was Boyd's R33 Skyline.

The car came to us after having a MAXXECU, injectors and fuel pump fitted and tuned elsewhere, but it was pretty much undriveable. The rear of the car was covered in soot and the AFRs were miles off. Looking through the ECU tables felt like staring at a game of Tetris. To make matters worse, the boost control wasn't working and it was only making 8psi. It would also stall every time you pulled up at the lights.

We strapped it onto the dyno, fitted our PLEX V3 knock box and started working through the issues properly. Fuel, ignition, acceleration enrichment, idle air control and after-start fueling tables were all corrected and dialled in. We then fitted a new MAC valve and turned it up — with NO knock.

The difference is wild. Boyd now has a completely different car and it finally drives the way it should.

If you want your vehicle to behave the way it should SAFELY give us a call today!

Peter’s immaculate FC Holden ute has been in for a proper old-school performance upgrade — and it’s now an absolute joy to drive 🔥

We supplied and fitted a triple Weber package to his forged 202, dialling in every last bit of response and power this combo had to give.

The result is a ute that’s not only a ball of fun to row through the gears, but still keeps that comfortable, usable feel Peter wanted for cruising 👌

Classic looks, proper performance, and all smiles behind the wheel — exactly how it should be 🚗💨

Leigh’s VL came in for the full treatment — and we definitely didn’t hold back 🔥

We built a tough 403ci LS topped with a Harrop 2300 supercharger, backed by a T400 and 9-inch diff combo ready to handle anything thrown at it. Packed with all the fruit, this setup lays down a safe and healthy 700hp at the wheels on E85 💪

Huge shoutout to Varuun from 101 Motorsports for the tune work 👌

With the braking package now upgraded to match the horsepower, Leigh can finally use every bit of it with confidence on the street and at the track.

This thing is an absolute weapon 🚗💨

A real deal survivor right here — Graham’s genuine GTS in beautifully original condition.

Factory 5L paired with the T400, plus factory A/C and power steering makes this one a seriously rare combo. Hard to find them untouched and still wearing all the right gear like this.

We had the pleasure of going over the car to make sure everything was in tip top shape, along with giving the factory air conditioning system a service so it’s cruising as good as it looks.

These are the kinds of cars that tell a story every time you look at them. Absolute credit to Graham for preserving such an honest example. 🔥👌
