Why combinations like this benefit from MoTeC solutions.

Here's the result of Michael's dyno run.

Making power isn't particularly difficult these days. Making power that's usable and controlled is where the challenge begins.

Unlike many of the high-powered AWD cars that come through the workshop, this R34 GT-T has to put everything through just two rear tyres. As torque levels climb, the way power is delivered becomes just as important as the number shown on the dyno screen.

That's where tuning and calibration play a critical role.

Boost control, torque delivery and traction management all need to work together to create a package that's not only powerful, but predictable and enjoyable to drive. The MoTeC M150 coupled with our custom firmware gives us the tools to precisely tailor how this car delivers its power, leveraging traction control and torque delivery in an unrivaled way. Ultimately, this RWD will be capable of accelerating at the rates of an AWD in the same class.

Following completion of the engine run-in period, Ryan carried out the final calibration and the result is a seriously capable street car that produces the sort of numbers many people associate with AWD platforms.

Not bad for an RB25 and two driven wheels.

Turn the sound up (headphones preferable) for this one.

Last week we posted about the TOYOTA GAZOO Racing range and how refreshing it is to see a manufacturer still building cars for enthusiasts.

This week, that featured car is up on the hoist with George fitting an ATS_Clutch twin-plate clutch to this GR Corolla.

It might seem like an unusual mod for a car that's still stock.

For the owner, he's starting with the end in mind.

Even modest tuning packages can quickly push the factory clutch beyond what it's designed to handle. As torque levels climb, clutch capacity becomes one of the first limitations owners run into.

We're fitting the ATS twin-plate for two reasons.

1. It gives the owner room to grow.
2. They're also drivable as heck.

Whether this car stays mostly stock, gets one of our Stage 0 calibrations to unlock some of the factory restrictions, graduates to fuel system and turbo upgrades, or eventually ends up with one of our larger turbo and MoTeC packages pushing towards the 700hp mark, this clutch won't be the limiting factor.

What we like most about the ATS isn't just the torque capacity. It's the drivability.

Twin plates have come a long way. ATS have done an excellent job of retaining factory-like manners. Light pedal feel, smooth engagement and none of the old-school on/off behaviour people used to associate with performance clutches. In some applications, we've even seen pedal effort lighter than factory.

Gone are the days where fitting a twin plate automatically meant sacrificing street manners.

What continues to impress us most about the GR Corolla platform is just how much potential Toyota left on the table. The factory package is excellent, but there's plenty more performance available for owners who want to explore it.

For this owner, the ATS clutch is simply the first step in that journey.

For the GR owners following along:

Some cars arrive at the workshop, somewhat finished.
Others earn every step of their journey.

Michael's R34 GT-T is a shining example of a proud journey travelled.

When this car first arrived, it was a little rough around the edges. The bones were there, but it needed time, patience and plenty of hard work to become what you see today.

Over the years, Michael has steadily transformed the car into a seriously tidy street machine. Under the bonnet sits a Powertune-built RB25 backed by a Precision 6266 turbocharger, E85 fuel system, MoTeC management and a brake package capable of keeping everything under control when the boost comes on.

It's one of those builds where every improvement has been carefully considered. No shortcuts. Just a genuine enthusiast steadily building the car he always wanted.

This week marks another milestone.

The engine has completed its run-in period and the car is back in the workshop for its final tune.

We call it graduation day.

There's always a sense of satisfaction when a project reaches this stage. After all the planning, parts, setbacks and late nights, the car finally gets to show what it's capable of.

On this evening, we saw this graduate put out numbers that put a lot of GTRs to shame.
Stay tuned for a video of this new grad screaming it's lungs out!

Not every product starts life as a product.

A few weeks ago we shared our prototype C1212 integration loom for the S15 platform.

Shortly afterwards, Simon gave us a call.

He was building his R34 GTT at home and wanted a clean way to integrate a Haltech UC10 into the factory vehicle systems. The challenge landed on Pete's desk and before long, a solution was taking shape.

What started as a one-off conversation quickly became a custom integration loom designed specifically for Simon's combination.

One of the things we enjoy most about projects like this is seeing what people are building in their own garages. Simon showed us photos of the car and it's clear a lot of time, effort and attention to detail has gone into it already. This loom will be one of those little touches that most people will never notice, but will make the overall package that much cleaner and easier to live with.

These photos were taken when Simon dropped by to collect the loom, with Pete walking him through the installation and discussing some of the future expansion options built into the design.

We'd love to see the R34 in the workshop once it's finished.

If you're working on a project that could benefit from OEM-level integration, motorsport-grade wiring and built-in expandability for future upgrades, get in touch. We'd be happy to discuss what might be possible for your combination.

Remember Jacko?

The bloke with the Midnight Purple III R34 GT-R we shared recently.

Well, it turns out that's just one of the cars in his collection.

Every time Jacko calls, there's another project underway. Another car. Another idea. Another plan. At this point we've started calling him Batman.

Nobody really knows what's coming next.

This time it's a brand new 79 Series LandCruiser.

And when we say brand new, we mean brand new.

Straight off the dealer floor. Window markings still on the glass. Protective covers still fitted. Not even properly settled into its new home before it found its way into our workshop.

Most people would spend a few months enjoying a new vehicle before pulling it apart.

Not Jacko.

This one is here for a clutch upgrade, turbo system, exhaust package and tuning.

The goal is simple: move as much air as possible, burn as much fuel as possible and make as many ponies as possible.

The funny part is that despite the performance focus, it'll probably remain one of the cleanest 79s you'll ever see.

Because that's the thing with Jacko's cars.

They get driven, modified and enjoyed.

But they never get butchered.

Some cars live comfortably off reputation alone.
Others quietly punch well above their weight forever.

Ian's GTi-R falls firmly into the latter.

He's been a long-time customer of ours and his little baby Godzilla is pretty special. Under the bonnet sits a VE-head SR combination paired with a responsive (albeit not baby) turbo package that comes on boost early and keep pulling for the heavens. The result is exactly what you'd want from a GTi-R: sharp, eager and deceptively quick.

What really makes this car interesting though is underneath.

Anyone familiar with GTi-Rs knows the factory driveline can become a limiting factor once power levels start climbing. To address that, Ian's car has been converted to run a CP9A Evo driveline package using some clever engineering and fabrication. It gives the car a much stronger foundation while retaining everything that makes a GTi-R such a weapon.

The end result is a car with a shorter wheelbase and narrower track than an Evo, but with a driveline capable of handling serious abuse. They're raw, direct and ridiculously fun to drive.

Right now we're preparing the car for fabrication work as part of its next evolution, which includes an all-new Turbosmart turbo package.

This should be an interesting one.

Stay tuned.

A lot of people know us for GT-Rs, Silvias and fast street cars.

Then every now and then something like Glenn's off-road buggy rolls through the doors.

Under the skin sits a Toyota 2GR V6 that was previously running a supercharger package we tuned some time ago. Since then the combination has changed. The blower has come off and the management package has been reworked, which means it's back on the dyno for a fresh calibration.

Looking around this thing, it's hard not to appreciate how purpose-built it is. Tube chassis, long-travel suspension, a rear-mounted radiator package and not a whole lot else. In fact, for today's tuning session it didn't even have a floor fitted.

Everything on the car exists for one reason: to survive being driven flat out over terrain that would destroy most vehicles.

It's a very different environment to what we're used to seeing on the street, but the fundamentals are the same. Get the package right, make it reliable, and give the driver confidence to use all of it.

Safe to say this isn't your average Camry.

Some manufacturers build cars for market segments.

Toyota built this for enthusiasts.

The GR Corolla is one of those rare modern cars that feels like it was signed off by people who actually like driving. Six-speed manual. Turbocharged three-cylinder. GR-Four all-wheel drive.

This one is in the workshop for a twin-plate clutch upgrade after its owner has been giving it a proper workout.

And honestly, that's exactly what these cars are for.

We've got a lot of time for Toyota's GR lineup. GR Yaris, GR Corolla, GR86, GR Supra — they're all different cars, but they share the same philosophy. Build something fun first and worry about the spreadsheets later.

We'd love to see what the GR crowd is doing.

What are you driving and what have you done to it so far?

A few of you have been asking for an update on Gary's S15, so here we go.

The gearbox and clutch have been removed, making way for the incoming PPG sequential transmission and matching clutch. We'll soon also be moving forward with the MoTeC C1212 dash integration with one of our plug in harnesses.

As with most projects, a lot of the big changes happen when the car doesn't look dramatically different from the outside. This is one of those stages.

We'll keep the updates coming as the sequential installation gets underway and the car starts taking shape again.

A look behind the curtain.

When Jacko unveiled his Midnight Purple III R34 GT-R at GT-R Festival earlier this year, most people saw the finished product.

What they didn't get to see were the countless hours, decisions and details that took place long before the car ever turned a wheel.

These photos were taken back in 2024 during the build process.

A lot of projects start with a horsepower target.

This one started with a standard.

-Purity-

Brand new parts only. No compromises. No shortcuts.

From the way every component was sourced, unboxed, laid out and handled, right through to final assembly, every stage reflected the philosophy Jacko brought to the project.

The thing that stood out most wasn't any individual component, or even the combination of components.

It was the patience.

The willingness to spend the extra time, source the right parts and do things properly, even when nobody else would ever know the difference.

Because the truth is, a build like this isn't really about the parts.

It's about discipline.

It's about holding yourself to a standard and refusing to compromise on it.

We're grateful Jacko trusted us to be part of that journey and help bring his vision to life.

The finished result may have stopped people in their tracks at GT-R Festival, but these are some of our favourite photos because they capture the stage very few people ever get to see.

And somehow, we don't think Jacko is finished yet...
