More Than A Dream: The GT-Z
He Had A Dream

One thing is common to all petrol-heads, regardless of our styles and loyalties. We’ve all had the dream, a personal masterplan for our interpretation of the perfect vehicle.

For most of us though, the dream stops there. The responsibilities of everyday life step in, forcing our dreams to exist only in tiny bubbles of imagination and small talk. But imagine a life where you threw it all on the line to chase that dream. To save furiously; to quit your day job; to learn new skills; to change your entire life. To give priority to that good idea and let go of your mundane, everyday responsibilities.

That’s what it took for Joel Dimmack to park his GT-Z dream project in his garage rather than it being parked eternally in a memory of missed opportunity.

I’ve already covered a lot of details in the car’s official debut, not just to Speedhunters but to the entire world. If this is news to you, give yourself 10 minutes to catch up here. It’s worth it, trust me!

So rather than rehashing most of the same info, let’s focus more on how the GT-Z came to be. How does a fleeting dream cross over to the real world? This story begins where most of ours finish.

Getting Started

As I’d alluded to, the GT-Z was originally nothing more than a dream build; an idea that laid dormant for many years, not too dissimilar to most of our dream projects. Over time though, the dream kept taunting Joel in his sleep and fighting for his attention as he tried to get through the less challenging tasks of real life.

Sourcing a suitable 240Z chassis was the first step, but hunting for vintage metal is anything but simple. A cheaper and cleaner 260Z or even a 280ZX could have simplified things, but in Joel’s eyes that would have diluted the project straight away. Finally, the car gods answered his prayers with chassis #1212. This was the car that Joel was searching for.

Even as one of the cleaner cars, it was still [probably] manufactured closer to your parents’ birthdays than your own. Almost as soon as taking up residence in Joel’s garage, the 240Z was sandblasted back to bare metal for a true assessment; it wasn’t pretty. Every one of its 46 years were etched into the bodywork, and it took over three months of tidying things up before the chassis was in a state clean enough to even think about further fabrication.

Dimmack_GTZ_Everingham_ (36)

That’s how the Z sat for some time; the first hold up a detour of sorts. After wrapping up a major work project, it was time for some skids. Joel spent some time in Japan where he hoped to fry tires and compete in the D1 Divisional Series (D1SL), in a car sourced from Powervehicles.

That trip was cut short, and the opportunity to compete was smashed into just as many pieces when his newly-acquired Nissan 180SX was hit pretty hard by a group of less experienced drifters at Ebisu, just days before the competition. Instead of dwelling on the unfortunate turn of events, Joel instead chose to use that disappointment as a 150-shot of NOS to speed up the project at home.

Pace Yourself

Up until this point the project had been a mostly solo affair, but if he was to stay true to the original vision, skills and knowledge outside of his experience were needed. The first step was to engage with PACE Innovations, a company best known in Australia for its involvement in creating the current ‘Car Of The Future’ chassis in the V8 Supercars series.

Dimmack_GTZ_Everingham_ (10)

I’m not jealous of what Joel had to do next, which was basically walking in off the street and trying to convince one of Australia’s leading race engineering firms that his project, his dream machine, and a drift car no less, was something they’d want to get behind.

It must have been an exciting presentation, because Reuben Laurenson and the team at PACE Engineering agreed to take on the project straight away. Modifying a beaten-up, 46-year-old chassis into something capable of competing at an international level was going to be a monumental undertaking, but perhaps the promise of that challenge is what sealed the deal.

Dimmack_GTZ_Everingham_ (50)

The bare shell was delivered to PACE where the team began by reinforcing and seam-welding the chassis. The Z was placed on a jig and twisted back to be straighter than ever.

That was the easy part, though. The next phase involved transplanting a factory Silvia cross-member, suspension arms and steering components. It’s one of those jobs that’s easy to do poorly, but difficult to do well, and setting everything square and correct to the wheel line and ride height ended up being one of the most time-consuming exercises of the build.

Fabricating the roll-cage was next on the agenda. Who would have thought that safety engineering could ever be classified as an artist’s masterpiece? Joel and PACE co-designed the cage, Joel used his graphic design skills to ensure the aesthetics stayed true to the 240Z, while the engineers at PACE made sure the structure would not only be safe but also maximise chassis rigidity.

Dimmack_GTZ_Everingham_ (22)

The gussets alone were drawn up in CAD, laser cut and dimple died from 4130 chromoly material to fit perfectly. This extra fabrication freedom gave PACE the ability to create the frame around the ideal driving position of its 6ft4 driver, and the final result exceeded all expectations.

Build Once. Build Right

On that note, this car is a masterclass in packaging, from the Bride carbon bucket seats, Tilton hanging pedal assembly, Woodward adjustable steering column and boot-mounted PWR engine and gearbox oil coolers. Wherever you look you’ll find an intelligent solution to a problem. I’m confident that within the clean and uncluttered finish are a metric tonne of other exceptional features hiding from me in plain sight.

Dimmack_GTZ_Everingham_ (18)

Sticking with the original vision, a VR38DETT was liberated from a Nissan R35 GT-R and set aside for the project. It was now time to decide on a gearbox and drivetrain package. Two options were on the table, but at this stage in the build the budget was thinning out considerably.

The cheaper option was a 370Z’s 6-speed transmission, which would bolt straight up to the VR38 block and was rumored to be capable of handling a lot of abuse. The second option, the PACE-endorsed choice, was to do it once and do it right. And so the hunt for an actual race-bred gearbox began.

Everingham_Dimmack_GTZ_ (54)

PACE took it upon themselves to engage the help of Albins, who came on board as the first product partner. Their solution was the ST6-I (inline) 6-speed sequential, which is the current control gearbox for V8 Supercars. Certainly, the Albins would be capable of withstanding whatever power and torque figures the 3.8-litre V6 could send down the line.

No longer would Joel need to daydream about flat-shifting gears in a proper race car; the added confidence provided by the Albins box would see him snapping gears with no hesitation.


Parts Shop Max was the next vital sponsor to jump onboard, supplying their Limit Break steering kit, with all adjustable multi-link arms for the front and rear of the car. PSM’s entire Silvia catalog of off-the-shelf parts was bolted straight into the factory subframe and cross members. A huge 70 degrees of steering lock is now possible.

The added adjustability of the GT-Z’s new steering, flexibility in handling and reinforced chassis has brought the 240Z into the modern era.

Godzilla’s Heart

With the fab work finished, the car was sent to Matt Stone Racing to be assembled and receive a coat of paint, hopefully in time for its scheduled public debut at Sydney’s World Time Attack Challenge.

Dimmack_GTZ_Everingham_ (25)

The last time we saw the car the majority of the engine bay was under wraps, and I mean that quite literally as the 240Z was just hours away from receiving a fresh coat of paint. The plumbing was still an early work in progress.

Dimmack_GTZ_Everingham_ (3)

A dummy block was fitted to help the team find the final placement while the real motor was rebuilt. Joel remembers this to be the most exciting time of the build; wave after wave of new parts were delivered almost hourly. It was a tuner’s dream, and an accountant’s worst nightmare.


In between taking shipments, Joel was basically an on-call delivery driver. If a hose, clamp or random part was needed to keep the build progressing, Joel and his ute could be found setting lap records along the Pacific Highway that runs between the workshop and Race Car Engineering, a local specialist racing store that miraculously stocked 99% of what was needed.

Dimmack_GTZ_Everingham_ (4)

The first thing you’ve probably noticed is how far back the VR38 sits in the bay. The block and twin-turbos fit snuggly behind the strut towers to improve the GT-Z’s weight distribution. It’s a tight fit, but done without recessing the firewall.

GCG Turbochargers specced up a pair of symmetrical Garrett GTX3076R Gen II turbos, the counter-rotating option made specifically for v-configured engines running a twin-turbo setup. The pair are a perfect match for the 3.8-litre V6 engine on E85, based on their ability to flow a lot of volume without sacrificing spool time. The smoother power curve is important for a drift car that needs torque on tap to break traction and fluctuate the throttle smoothly, especially from the chase car position.

The dual GCG snails are accompanied by a pair of Turbosmart Pro-Gate 50mm wastegates. Bonus points are awarded to the GT-Z for venting its screamer pipes to atmosphere right out of the inspection lids on each side of the bonnet. It meant some extra work for the fabrication team, but I doubt they’d not be impressed with their handiwork while the Datsun is spitting three-inch flames skyward.

Engine temperatures are controlled by a beautiful V-mount intercooler and radiator package courtesy of PWR. The GT-Z’s engine bay was laser scanned by PWR and a bespoke setup capable of the cooling demands of a top-level competition car was developed to make the most of the limited space available. PWR engine and gearbox oil coolers are also fitted.


The final piece of this mechanical puzzle was designed and supplied by Tractive Suspension, the same people responsible for many high-end OEM active suspension setups. Unique 3-way adjustable dampers were built and assembled in the Netherlands, and supported by TT Suspension in Sydney, Australia.

With the last of the big mechanical tasks complete, the remaining time went into fitting the CarbonSignal Moonbeam bodykit which arrived at the very last minute, and then applying a very quick coat of paint to have the GT-Z ready for its WTAC debut.

Dimmack_GTZ_Everingham_ (21)

The car was painted a custom colour Platinum GT-Z, a metallic charcoal that blends perfectly into a sea of carbon fibre and billet aluminium. A carbon roof was also made up and blended seamlessly into the body. Not only is it a great weight saver, it’s such a cool, hidden detail.

Dimmack_GTZ_Everingham_ (37)

Building the GT-Z was no easy task, but really, nothing good comes easy. Everyone involved with the project provided some very clever solutions to what could be considered a near-impossible task.

With the talent behind the build, and Joel behind the wheel, my eyes are set to the future. I’m very keen to see the full potential of the world’s very first GT-Z unlocked.

Lemme be the first of many to say that I just poo'd a lil'


rip john ritter


What does it weigh


I couldn't tell you exactly, but it weighs around 1000kg (wet)


Best car I've seen on this site...EVER!


Me too, but I'm obviously biased...

Matthew Everingham

That's a BIG call.


Why Rota wheels on such a no-expense-spared build?

At least put some PISANGs on that mug!


Rotas are actually pretty high quality wheels(from what I know/some of them), you just dont pay for the brand.

Matthew Everingham

From my understanding, which may not be the entire story, the wheels were ordered as place holders in the best guess for offset. If you read the build story you'd know how little time they had. Ordering a confirmed size after it came together wasn't an option.
I think GT-Z may still be on the hunt for other rims.
Which is why I chose to not get specific on wheel choice in the article.


Yes spot on, time restraints don't just hinder the build but limits your options on particular details, especially in our case we needed a certain look, size and offset that 'might' work so we can determine clearances, ride height, tyre choice & rim size. There are a lot of great companies making beautiful wheels out there, I'd honestly really love to partner with someone and develope my own design bespoke to this vehicle. There's levels to this game and everything can't happen over night but the development doesn't stop.


Fair enough, and thank you for the reply. So, you would consider the ROTA wheels as your final choice or not?


The wheels look cool! Why pay more for the same wheels just marked up in price. They are all made on the same machines, with the same metal. It is a waste of money, unless you just like paying extra money for some company that has done nothing for you. All these wheel companies have stolen designs from each other. The Japanese stole not only wheel designs from the US and the Europeans, but the also copied the cars designs... The Z is a knock off of American and British designs. Since the car is a knock off, it is a perfect match for knock off wheels.


The Z a knock off of Brit and American? The closest Brit I can see that's even close is the Triumph GT6. First released in '66, with an i6 and between 95-110bhp. Top speeds from 106-112mph. When the datsun came out 3 years later (bear in mind the concept was released the same year the triumph came out) it wiped the floor with the Triumph in every single way, bhp around the 150 mark, top speed over 120... and since Americans didn't know what lightness and handling was at that time, I don't think there are any comparable cars, just because it came out later does not make it a knock off especially if it's better, much better.


The GT6 was a design based off a family saloon car (The triumph herald), sharing the separate chassis, suspension and engine. The engine itself was a 2.5l six based off a massey ferguson tractor with a massive stroke, so it's hardly refined. The Z isn't really comparable, as it was a brand new chassis, with a far more advanced OHC engine. This is what Japanese manufacturers do best, take an idea and improve it. The same applies for the Mazda MX-5.

A rival for the 240 from the UK would be something like the Lotus Elan, an Austin Healey, or maybe an MGC or MGB V8.


and before someone says the i6 mustangs and other i6 "muscle cars", the BHP for a 2.8 was a joke circa 100bhp.


I'm not sure you understand what 'knock off' means because a Z is far from a 'knock off' car. Yes, there's a lot of Japanese cars of this era that draw inspiration from their US & European counterparts, but that's something that works both ways.

For the record, I despise Rota but I understand that wheels are a consumable in drifting and not everyone is willing to wreck expensive wheels when the cheap wheels will perform much the same at a lower price point. I don't like it, but I understand it.


Whats actually wrong with Rota's?
I genuinely haven't seen or heard anyone talk negatively about them before. It's always just been another wheel manufacturer to me


Wow that's cool. Old cars with modern parts are always a fun read. Kinda want to see video of spitfiring waste gates coming from the damn hood though, seems awesome.


That is a thing of beauty. The packaging of the engine is particularly noteworthy.

Would love to see some videos of this ripping about.


this has got to be the best datsun in the world but i wish I could download all the photos at once


anybody knows what kind of animal are those ?!

Matthew Everingham

Radical Racing. Mike wins 15 points!


haha, you will win another 15 points for spotlight !


Those are a single make series car. Australian Prototype cars.


they say in the video that its a radical, about 1:25 in. they are not exclusive to Australia and have race series around the world. although it seems to me that the racing series is called Australian Prototypes


ultima GTR? or maybe a radical?


Throughly impressed by all the work! this is a fantastic project and a tip of the hat to everyone who made it happen. I am particularly impressed with the engine being completely behind the strut towers!

I have a couple questions:
"Joel and PACE co-designed the cage, Joel used his graphic design skills to ensure the aesthetics stayed true to the 240Z, while the engineers at PACE made sure the structure would not only be safe but also maximize chassis rigidity."
could you go into what aesthetics Joel worked on? this sentence is slightly confusing to me as i would think that saftey and chassis rigidity would be enough to define the entire cage as it is. I would just like to know more as the cage looks amazing.

Also, it doesn't look like the front inner fenders are tubbed, can Joel get the full 70 degrees out of the PSM parts?

finally, how hard is it to make shock adjustments? it looks as if you have moved the top mounts both front and rear. is all shock adjustment at the bottom? or is there and access hole hidden away somewhere?


The front uses external canisters for high and low speed compression/bump adjustment. The hose makes the mounting position flexible. Adjustments therefore can be made easily. In the rear, the high and low speed compression/bump adjustment is positioned at the body of the shock (shown in the pictures of the article). Going off the pictures provided by Matthew, it might be hard to reach these adjustments with the wheels in place, but they might have figured out a solution for this too.

The rebound adjustment is on the bottom of the shocks, both front and rear.
(I tried to add a picture of the shocks before they were sent to this project, don't know if it worked)

If you have any more questions regarding the shocks, feel free to ask.
Koen (Application Engineer at Tractive Suspension)


Thanks! The front packaging is interesting because it looks like the strut top has been moved outboard which causes a bunch to be hidden under the fender. from what i understand this is a common thing in drifting as it corrects the geometry that is changed with the longer control arms from PSM.

when are you going to make a road/track setup for 944's?


Road/Track setup for Porsche's we do already offer (mainly trough our partners DSC sport in America and TT Suspension in Sydney Australia). However, the 944 isn't a platform we developed thusfar.
If you contact either of those partners, they can give you more information about the possibilities, since we offer high-end suspension technology, expect a corresponding pricetag.
Converting the 944 onto semi-active suspension would be a huge improvement though.



Amazing My 240z got nothing on this beast!


Still alluded and eluded. I got a notification saying this had been fixed, but...

Hit Ctrl-F5 for a proper refresh of page.


Not on iOS. But Okies


Dream car! Need to see it ripping the track!

few Q - are the throttle boddies stock?

- whats wrong with body paint? It looks like engine bay and interior is better quality wise than exterior?

Matthew Everingham

If I had to guess regarding the paint, I'd put it down to a lack of hours and the fact that a proper wrap/paint job will come with sponsors in the very near future.
Personally, I dig the rough edge the paint brings to the build.


Did I miss the mention of the multi-link rear susp conversion? These cars came with Chapman struts, and this looks like it has modern Nissan/Infiniti parts out back.

Matthew Everingham

It's covered, but not in pics. Sorry, you'll have to read. :D


Reading is for LOSERS!

(Kidding. I'll try to track down more info on the project.)


Hey i have a few dudes, the gt-z was originally a nissan 240z? The name gt-z was the name of the proyect, it isnt a name of a car, no?


Did anyone else's eyes have an orgasm at the sight of this beautiful Z?? Makes me want to build my dream Z.
