The Final Entry: Engineered to Slide Hilux

The story so far

Good things come to those who wait, or in Nigel Petrie’s case, they come to those that dedicate every last minute of their spare time to a dream, to a vision of creating something bespoke. We’ve come across some pretty inspiring builds over the years here at Speedhunters but the ‘Drift Ute’ is unlike anything out there. Thanks to Nigel’s posts keeping us updated with the progress of his build over the years, we’ve seen this project materialise, getting a glimpse at the amount of work and sheer commitment required to take an idea from one’s head, and turn it into reality.

Now that the Engineered To Slide Hilux is all completed, it’s finally time to indulge in its details and appreciate the years of work that have been poured into it. I’ll let Nigel take over…

Nigel-Petrie-Drift-Ute-02

Welcome back Speedhunters, it’s been nearly three months since the last build update and I am delighted to bring you the finished product.  I want to give you some insight into what’s been happening in the last months since that very first test drive. Constructing a car from nothing has its challenges; most of these challenges are extremely hard to overcome but I think that’s the fuel to my fire, that intense headache that just won’t go away until the issue is resolved, gives me the passion to continue. I took a little break after the build was complete but not finished; by that I mean it was running, driving, and aesthetically together but I needed to make sure everything was ready for paint and powdercoat. I started to think about the chassis and how I wanted it to be finished. Every time I wipe the tube down with thinners I admire the steel’s brilliant colours, but as the moisture of the thinners disappears so does the colour. I started to think about how I could harness that deep clear look as the finished product.

Nigel-Petrie-Drift-Ute-36

It was this challenge that took me to Colourtech Powdercoating Geelong. Firstly I asked the guys if they had clear powdercoat. They did but they had reservations about how it would work. I decided to give it a go and after getting home I stripped my BMX down to raw steel and returned it to them ready to coat. When I returned to pick up the frame, I was blown away: the steel had the deepest shine, the welds had the most beautiful contrast to them and the way the heat marks blended in with the steel had to be seen to be believed. I quickly reassembled the BMX and started testing its durability. It held up extremely well and I was so glad to have a final chassis finish locked in. A few days later I would return to a sight I had been dreaming of for two and a half years: before me was the finished chassis in all its clear-coated glory. Not only the chassis, but the steering column, dash mount, suspension arms, subframe and many other hand fabricated pieces. The powder is electrostatically charged onto the parts allowing every little area to be covered.

Nigel-Petrie-Drift-Ute-01

Later on, Tim from Breakwater Panels called me and said the bodywork was ready to pick up. I was like a kid on Christmas morning. I arrived to pick up the perfectly flow-coated Toyota Superwhite body and I couldn’t be happier. It was better than I ever imagined.

Nigel-Petrie-Drift-Ute-32

The next few nights I put together the sub assemblies, making sure that everything was complete and ready to go. It was at this point I reflected on what I had been through. Handling each part and seeing it in its finished state gave me flashbacks; the amount of time and effort gone into each one will never be understood by anyone but myself.

My friend Dean and I came up with this brilliantly stupid plan to assemble the car in an abandoned factory with a roof mounted camera tethered to a laptop and lit with some studio lights. What’s stupid about this you ask? It was a ridiculous amount of work and to do it without bumping any other parts was a nightmare. The results were insane though and I can’t thank Dean enough for his help. After bringing the Hilux back home it was done. It took a few nights to really kick in that it was finished. A quick flick of the ignition and a press on the start button confirmed that the electronics went back in as they should. I had just built the most complex automotive puzzle and it all went together like clockwork. Let’s take a little detailed look at it…

Completion achieved

Nigel-Petrie-Drift-Ute-19

The plan from the beginning was to keep the body as stock as possible: this includes the stock Superwhite Toyota paint work.

Nigel-Petrie-Drift-Ute-20

Surrounded by the FRP shell and alloy under-tray, the steel structure is the most visible and admired aspect of the build.

Nigel-Petrie-Drift-Ute-08

The suspension itself uses MCA shocks…

Nigel-Petrie-Drift-Ute-05

… chromoly arms and QA1 rose joints. The layout is similar to that of a Nissan S15 multi-link rear end.

Nigel-Petrie-Drift-Ute-06

The plan at the start was to use a factory S15 cradle, but after building the chassis, this idea was ditched in favour of something better-looking. I improved the geometry, solid mounted the diff, then made up the arms.

Nigel-Petrie-Drift-Ute-07

The rear swaybar is similar to the front with V8 supercar blade adjustable ends tied together with 1 ¼ chromoly tube and brass bushes. Like the front, these blade ends will be remade to a softer rate to reflect the chassis weight.

Nigel-Petrie-Drift-Ute-21

The diff is an R200 with a mechanical two-way LSD inside it. The shafts are your usual S-series five bolt shaft and the knuckles are S15 items.

Nigel-Petrie-Drift-Ute-09

Having all the freedom in the world with a ground up build gives you many options. When it came time to select a fuel tank, I did things a little different and selected a spun alloy upright tank that eliminates a lot of the fuel surge a flat tank would have.

Nigel-Petrie-Drift-Ute-04

The exhaust exits the diffuser and is finished with twin 80 mm alloy tips, with the equal length manifold and TD06 turbo…

Nigel-Petrie-Drift-Ute-10

…  it equips the SR20 with that mid-mount rasp that would be at home on Meihan Circuit.

Driven by a unique style

Nigel-Petrie-Drift-Ute-11

This is my intended ride hight: with a ground-to-floor clearance of 70mm all around it’s quite high. There are low points but these are all easily replaceable and will wear themselves in over time. The Bridgestone Driftmasters were made in 2002, the body style is from a 2002 Hilux and it all ties in with that theme. I grew up dreaming about drift cars from this era of Japanese drifting and I wanted to encase this in the most unlikely of body choices. The front wheels are 8.5×17 ET0 and the rears are 9.5×18 ET0.

Nigel-Petrie-Drift-Ute-22

I run 17/18 stagger on all my cars: I use 17-inch up front to get maximum steering lock and guard clearance while the 18-inch rims in the rear achieve maximum tuck. The brakes are a simple mix of Wilwood pedal box, manual rear lockout valve, Earls lines and Z32 calipers. In a lightweight car like this, it’s ample braking power on a budget.

Nigel-Petrie-Drift-Ute-12

Things are pretty simple inside…

Nigel-Petrie-Drift-Ute-14

… I wanted to leave as much of the chassis and the powdercoated finish as visible as I could.

Nigel-Petrie-Drift-Ute-15

The RB25 gearbox that broke in the WTAC Tectaloy drift practice session is now out and will be replaced with a six-speed sequential transmission.

Nigel-Petrie-Drift-Ute-16

Access to the gearbox and exhaust is gained through the removable sheet metal panels while the Racepak IQ3 Dash supplies me with all the information and alerts from both the Smartwire and Link ECU.

Nigel-Petrie-Drift-Ute-34

A quick look at the Wilwood pedal box and the braided hoses and Earls fittings that I laid out through the firewall.

Nigel-Petrie-Drift-Ute-17

The seats are only temporary as they are out of my PS13. When funds permit I’ll replace these with Vios 3 Japan edition Type R seats with higher thigh support.

Nigel-Petrie-Drift-Ute-13

There are minimal electronics inside the cabin due to the simple single wire Smartwire switch panel handling all of the controls.

Nigel-Petrie-Drift-Ute-18

The finished Hilux is a sight I could, and will, look at forever. It’s almost understated on the outside and invites you to look under its skin where all is revealed.

SR20 power

Nigel-Petrie-Drift-Ute-24

The engine is the SR20DET out of my PS13. It has a built bottom end with some upgraded cams and valve springs.

Nigel-Petrie-Drift-Ute-29

It wasn’t what was inside the engine that I spent most of my time on, it was what was hanging off it.

Nigel-Petrie-Drift-Ute-28

The hot side is an intricate mix of parts to fit the chassis both physically and aesthetically. My goal with all the components was for them to look good, work good and be easy to service.

Nigel-Petrie-Drift-Ute-25

The only thing that wasn’t majorly modified was the long motor itself. I reworked the rocker cover to feed the integrated oil catch tank…

Nigel-Petrie-Drift-Ute-31

… house the new coil mount and allow me to fill it with oil from a different position. The timing side of things was also upgraded, with a custom trigger wheel on the ATI balancer and a GT101 telling the Link ECU the engine speed. The ECU is also told about cam reference with a custom inbuilt GT101 reading off the exhaust cam.

Nigel-Petrie-Drift-Ute-26

As you look through the engine bay and into the front suspension, you will notice custom chromoly lower control arms, caster arms and MCA uprights; it’s all bolted to the chassis via QA1 rose joints.  The knuckles are S15 items I modified to optimize the steering lock within the chassis. The front swaybar uses V8 Supercar blade adjustable ends and connects to the chassis via 1.5” chromoly tube and bronze bushings.

Nigel-Petrie-Drift-Ute-30

A little detail of the front strut towers.

Nigel-Petrie-Drift-Ute-27

The cooling was left up to PWR: the QLD factory took all my drawings and made me a custom solution for air and water temperature control, all plumbed together with custom stainless steel piping.

Nigel-Petrie-Drift-Ute-33

I’d be lying if I said I wasn’t the least bit apprehensive about taking the Hilux out on track with 30 of the world’s best drifters at the Tectaloy event during the World Time Attack the other week. Lining up on the start line and staring down the straightaway, I tightened my belts and took a deep breath inside my helmet. A ridiculous amount of hours over the past 2.5 years had come down to this. I strung together about eight laps before coming in to swap to my RPS13. In those eight laps I started to get a real feeling for the way the Hilux behaves: it’s unlike anything I have ever driven, and the amount of mechanical feel I received through the steering wheel was insane. You hear people talk about a stiff chassis but you never fully understand the impact until you drive something like this. It was far too short-lived though and a couple of laps later, I sheared third gear in the RB25 gearbox with a very harsh unloaded over-rev that broke two rockers in the head. As I write this, I’m planning on upgrading to a sequential dog engagement gearbox and getting back out on track ASAP. This car was not built to compete or comply with anything; it’s simply a vision that I wanted to turn into a reality. In the two and a half years from conception to completion, I’ve learnt an amazing amount. I wouldn’t change a single thing – but I would do things a lot differently if I had a chance.

I want to thank everyone for their support and I hope that one day they can see this in the flesh to get a real feel for the amount of heart and effort I poured into this build. I can’t wait to cover everything in molten rubber!

Such a inspiration you have give me through this build. I have seen the documentary twice, and I am equally blown away every time afterwards. I really hope I get the chans to see it live someday, but i dont think your comming to Sweden or Norway with the car... But what an epic build anyway, and I hope you enjoy the car to the fulliest! Best regards from Sweden! 

Ps I hope you get som Engineered to slide sunglasses in the shop someday, they would look Awsome!

The powdercoat-cleared steel frame is absolutely beautiful. I'd noticed the rear tub cover doesn't make an appearance in any of the pics, but its easy to see why - how could you cover anything up!?

Excellent build, and very tastefully done. I love it.

Probably one of my favourite builds I have ever seen. I remember seeing it a while back and it just blows me away. Although im not much of a drift fan, I like to imagine one that would dominate a time track. But nether the less a sick build.

Nigel, huge inspiration to so many people! I love the fact YOU did it, not send it off for a shop to build. Do you have other ideas in your head for a new project a few years down the road?

Nigel you are nothing short of a genius. When I attempt to imagine all the tiny little details of you building every aspect, I start to be impressed by how quick you puled it off. Everything on the truck came out awesome. Part of me is a little sad there will be no more build updates on it. Every good thing comes to an end, or gets finished in this case. You deserve every bit of attention and award you are going to receive. Time to build something else we can all admire!

2 YEARS LATER!!! 


I read all the posts leading up to this, the final product and, to be honest, after almost a year of absence, I thought that was it and we weren't going to hear from this build again but an update pops up every few (million) months that teases us.

Definitely build of the year, car of the year, speedhunters car of the year, year of the year, year of the car, etc.

Amazing build Nigel, can't wait to see it up and running again when you get the new box! 

Great photography Dino, the many close up shots are pure eye candy and you've really nailed the wide shots that show the fiberglass work and stance. It's odd because I know what it is... but it's true, from a distance it's very understated, yet up close, it's spectacular and so tastefully done.

I've been following this build since it first started and is one of my favorites, Glad to see it finally got finished, it's awesome I really wish I had the skills to fabricate my own custom track car from the ground up.

This thing reminds me of the build quality of cars created by my late friend Shaun Carlson of Nuformz or my buddy Robbie Miller of Robbie Miller Race Cars. Just built from the ground up with every part of the vehicle being immaculate. Every weld, every bracket being made with a purpose. This car drips of high standards of quality and pure perfection. Great job and it was fun to see it progress over the year.

Gotta respect it. It's been a long time coming. I still remember when this build was first featured... This is quite an achievement. Cheers!

Okay, so I think it's an awesome build, but I have a question. What makes this an "ute" intead of a compact pickup? My understanding of a ute as an American was that they were something like an El Camino, whereas the Hilux just looks like a straight pickup. Am I mistaken?

@japanophile25 as far as I know, a ute is on a car chassis, whereas a pickup is on a truck chassis. Not too sure though.

@AutoX_a_Truck he says most all he needs to say in the videos the DOM tubing is obvious with the addition of chrome moly on the control arms and other crucial load bearing components.. if your asking for specific measurements nobody is going to take that trouble on a custom piece like this.. you would be better just dong a custom project yourself starting from the bottom and engineer it how you want it..

@aussieANON @japanophile25 Just aussie speak for pick up, usually referring to a car chassis trick but used to also for your regular pick up.  It sounds cool saying it that's for sure :)

AutoX_a_Truck

@ThomasScott1 @AutoX_a_Truck 

I watched a few of the videos and looked in a few other places, but I wasn't able to find some basic starting point info that I was looking for.... Something akin to, "I used 
1 5/8" x .134 wall 4130 here (and as a bonus I used it for this reason) or 1 3/4" x .120 wall mild steel here." I am also particularly interested in the rectangular tubing that comprises the perimeter. Sure, there are plenty of chassis engineering books and theories, but many suggestions for specific components refer to specific vehicles that are more standard/common and/or vehicles built for specific disciplines or racing. This wild ride interests me because it is also a relatively small, lightweight truck based vehicle. Understandably, in competition there are some secrets, but I am not interested in the measurements of the specific finished components. However, since this guy actually built and tested a unique chassis for a unique vehicle where there was likely little to work off except for basic theory he has a ton invested in what material was chosen and why so no worries if giving out info is too much to ask.
