Since we featured Peter’s stunning FB in 2018, the heavily-customised Holden has had a serious crack at the top awards in our sport.

At Street Machine Summernats 34, the FB finished in the top three for the Grand Champion chase, alongside Jason Mansweto’s XW and Jason McGrath’s LC Torana.

And the pair did it again at Red CentreNats 2022, seeing off a high quality field to again finish in the top three for Grand Champion glory.

Like most of the competitors, the twin-turbo V8-powered FB stuggled with traction on the ASID track for the car’s first-ever pass down a drag strip.

“We wheelspun the whole way,” says Peter’s son Daniel. “We went 14-seconds, but I’d like to think we could run an 11 or even a a 10 if we could hook up.”

The FB performed well in the other driving events to seal the top three spot. The whole Beauchamp clan was in Alice to enjoy the action and came away with the highly-coveted People’s Choice gong and placed in the top five Elite.

Now, read on to see how the car was transformed from family flogbox, to one of the best all-round streeters in Oz.

Thanks to the halo effect of factory-correct muscle cars, our little hobby of street machining has had its ranks swelled by people restoring/refreshing and cruising more modest timewarp stuff in the past few years. Few can afford $100K-plus for a race special, but the kid cruising a stocko Commodore, Kingy or Falcon 500 isn’t laughed at anymore. Isn’t fashion funny sometimes?

But even with these renaissance cars sparkling in the street machining spotlight, at the top end of town there remains the elite-type car builders who continue to inspire us with mind-bending builds such as this terrific green, two-door-converted FB Holden sedan.

It’s owned by Peter and Judy Beauchamp, and a generation ago, it was simply the family truckster!

Unlike Chevrolet with the similarly styled 1955-’57 models, Holden didn’t make an equivalent two-door, but there have a been a few keen Aussie street machiners over the years who have done it DIY – now including the Beauchamps. Other custom touches here include no badges and no lock barrels

“We bought this about 28 years ago; it was all we could afford,” Judy explains. “When we bought it, it got a quick once-over – some paint and an interior clean-out to get it going. It was the family car for more than 10 years. The kids grew up with this car – Mum and Dad doing the runaround and dropping them at school. One day I even carried a cow in the back of it!”

Although the FB now has a tilt front end, it retains panel gaps between the bonnet and guards for a stock-type appearance. That also helps the grille’s top bar – three-piece from the factory – look correct, too. Retaining some shine with the headlight bezels, grille bar and windscreen surround keeps a hint of the car’s original character without making it look monotone or sterile

The rebuild began about 15 years ago, and as with most long-term builds there was a soap-opera script of love and hate, satisfaction and disappointments.

“We took it off the road with the intention to do it up,” Judy explains, “but it was never supposed to be this long! We got stuffed around a bit by a workshop. Three steps forward and one back – the usual story that many people seem to have when they’re building a car.

The ex-Lexus donk was wired ’n’ fired before the car was blown apart and the engine rebuilt by Aaron at Advanced Performance Machining. It’s built to cope with 14psi and an easy 800hp, but for street duty and Grand Champ aspirations, driveability will be a priority over power when Powertune at Wetherill Park spins it on the rollers

“But one day about 18 months ago my elder son Daniel said: ‘Mum – enough is enough. We need to get this finished. It’s been long enough.’ And that was the push we needed to get it done.”

Hubby Peter takes over the yarn: “We did plenty here at home,” he says. “No shed! Just a double garage.”

You’re forgiven for not recognising this straight away, but it’s a 4.0L Lexus all-alloy quad-cam V8. This one is piped with a pair of intercooled T04 turbos, and although factory-injected, it had a complete rethink with Autronic SM4 management and E85 fuelling. It’s yet to be flogged on the dyno for a tune, but it will happen sooner rather than later

The car was stripped and put on a rotisserie, where most of the floor was cut out. The plan was to install an HQ Holden half-chassis to replace the FB (and all pre-HQ Holdens’) bolt-on Y-frames; this work was performed early in the build by Jeff’s Chop Shop. Later, the front doors were stretched around 200mm by Camden County Customs, who did the tilt-front conversion, too.

As well as the door stretch, the front and rear quarter windows have been binned and the side glass replaced with special-build toughened panes. Get this – Peter said he paid less than $400 for the new made-to-measure glass.

The Lexus V8 up front was always part of the plan. “Choosing this was as much about doing something different as it was about power or performance,” Peter reckons. “We could have gone the usual small-block Chev or Holden or the LS route, but this one just had extra appeal for me. It’s all-alloy and has six-bolt mains. I’d seen these Lexus motors in other cars, and with double overhead cams and all that, they perform really well.”

The engine was bought in an imported half-cut. As the Fast Fours & Rotaries crowd learned two decades ago, an ex-Japan chopped-in-half car is a handy way of getting just about everything required – engine, hoses, fans, wiring and computer – to be shoved into something else.

“It was like a jigssaw puzzle,” says Peter of the engine’s installation. “Everything had to be considered with everything else.” Making the situation a little easier was the fact the FB’s ‘new’ HQ Holden rail-type chassis opened up a bit of engine bay space compared to the high sides of the original bay.

“We trial-fitted everything; we put the motor in and got everything running before disassembling it all and finishing it off,” Peter explains. “I had a bloke over at Smeaton Grange build it for us.”

Based off FG Falcon ute seats, the factory-standard-installed flip-forward mechanism makes getting in easy. Handy! The Dakota Digital dash is based on that of a ’57 Chev, and it fronts a Flaming River steering column. There’s central locking and fast glass, too. The windscreen is also a band-tinted brand-new piece, while the rear screen is an original as new ones aren’t available. Break one and a replacement must be picked out of a paddock!

That’s Aaron at Advanced Performance Machining. He rebuilt the Lexus V8 with a few upgrades: JE pistons, Kelford cams and ARP studs. The intake manifold on the standard Lexus isn’t too generous, so it was replaced with a built sheet-metal one, with forward-facing 90mm throttle. The turbos required fabricated manifolds, while the exhausts were fabricated in sections, linished seamless from front to rear.

The rear seats are shaped to match the front but are built on fabbed frames. Attention was given to aligning the front and rear seats with each other so they all sit square

Behind the Lexus is a transbraked C4 auto. Supplied by Rocket Industries, it’s good for 800-plus ponies and was fitted using a Dellow bellhousing. Peter makes special mention of the torque converter: It’s pretty much half Toyota/Lexus and half-Ford to suit the engine/trans combo and a streetable 2800rpm.

No headrests mean the cabin remains bright and airy

After having the car sit for three years elsewhere waiting for paint, the Beauchamps had Leo at Muscle Car Restorations in Blair Athol apply the colour. Peter gives him a big wrap, reckoning his wisdom and experience seems beyond his 26 years. “I delivered the car in primer, but he took it all off and started all over again,” he says. The paint is House Of Kolor, but this particular shade of green is not from the usual catalogue!

The interior is the work of X-Trim in Smeaton Grange. Beginning with Falcon ute seats and an empty cabin – with little tubs messing things up at the rear – the team crafted a gorgeous Biscuit leather interior.

Summernats 31 was the car’s first outing, with the Beauchamps coaxed by the ’Nats judging team into presenting it as an Elite contender. Good idea! It scored an Encouragement Award and 2nd Top Custom behind Kylie and Adam Perry’s astonishing Tailspin – also an FB Holden.

“I was asked to enter Grand Champion, but I said ‘nah’, not on a brand-new engine,” Peter says. He’s also mindful of the need to keep the car clean and tidy for more displays in 2018. “We’ve got Meguiar’s MotorEx in Melbourne and we’ve been invited to Red CentreNATS in Alice Springs, too.”

But once the Beauchamps have got some kays under the tyres – and the tune sorted – they are keen to have a crack at Summernats Grand Champion in 2019. Bring it on!


The Lexus 1UZ-FE engine is an all-alloy 4.0-litre quad-cam V8 that debuted in the first-ever Lexus LS400, launched nearly 30 years ago at the 1989 North American Auto Show in Detroit. With four valves per cylinder, the 3968cc (243ci) top-line Toyota-designed V8 delivered around 192kW, more than Holden’s also then-freshly injected 165kW and 180kW 5.0-litre V8s.

As well as alloy block and heads, the 1UZ-FE has six-bolt mains, a steel crank and rods, tough pistons (under useful 10:1 compression) and is almost perfectly balanced from the production line.

During the engine’s design phase in the 1980s, Toyota wanted to improve on its own impressive in-house reliability and durability standards, so looked to aviation specifications for new standards in quality control. Toyota’s aim was to not only match Mercedes, BMW and Jag with its new luxury sub-brand for the 1990s but blow them away. And these days swapping one of these early alloy V8s isn’t a silly idea!
