Spirit Road: The Minimalist Miata With All The Parts
Miata Is Always The Answer

Mazda Miatas are universally loved. You might see an older lady cruise by in a stock Miata and, not a minute later, a kid-owned rendition slammed to oblivion drive by, too.

These little cars are slow but quick, cramped yet just big enough, cheap, fun and oh-so-versatile. Miata is always the answer, a mantra which carries over to many subcultures within the car world.

But with so many different examples buzzing around, it’s hard for just one to stand out. However, if any Miata can differentiate itself from the others, it’s Kevin Truong’s.


Many, if not most Miata owners see their little cars as either just a way to get around or a fun weekend track car or back-roader, but only a few true enthusiasts feel as deep an affinity with their Miata as Kevin does. This car is Kevin’s routine spiritual release, and due to this connection he has given his Miata the name Spirit Road.

After a long day of work he goes out for a night cruise and everything aligns. It’s just him, the car, and the road.


As such, Kevin has poured his soul into this build, modifying every last square inch of the car. In fact, I don’t think I’ve ever seen a mod list for a Miata as detailed and as long as Kevin’s.

The full list can be seen below, but it’s Kevin’s path towards completion that we’ll focus on here.

Love Story

Kevin and Spirit Road’s love story started in December of 2017 and, like any big project, there were some bumps before things ran smoothly. It began with a long day of driving from Los Angeles to Las Vegas and back for a set of Jenvey ITBs and a Pit Crew Racing high-rise header.

Ultimately, Kevin decided to build his entire car around these two parts.


Actually, he didn’t even own a Miata at this point, but soon after Kevin found a prime bone-stock example out in Bakersfield, California and started adding some bolt-ons to the ’97 NA to get things rolling. This included an ARC intake and airbox along with Arrive cold air intake piping.

He lowered the car, found a set of beat-up Panasport wheels (which were subsequently restored), and finally enjoyed his first drive with the beginnings of his vision intact.


Eventually this vision grew – because there’s no such thing as a finished car — and Kevin was inspired to make the Mazda as much of a 1960s/1970s throwback as he could. The idea was to transform the Miata and alter the entire aesthetic; Kevin took inspiration from his ’71 240Z and his love for the Datsun 1600/2000 Roadster when beginning to build version two of Spirit Road.


Inside and out, everything was to be modified.


Kevin further explained his inspiration: “My dad used to take me to Chinatown in LA on Sundays. At this dim sum restaurant there was this cigarette vending machine. I remembered seeing the John Player Special cigarettes. And many years ago, I remembered seeing JPS livery on F1 race cars and others. So the Spirit Road logo is inspired by ’70s motorsports regalia and lifestyle so to speak. Everything kind of just came together by chance, inspiration, passion, and memories.”

But with the new expanded vision came bigger challenges.


Kevin still had the Jenvey ITBs sitting in his room, so the decision was made to finally fit them. But it wasn’t a totally straightforward proposition. “The car was parked for two months while I wrenched away [to install] the ITBs,” he explained. “The fuel hard lines on the Miata are not a common size, [so it] was a nightmare finding the right fittings, sleeves, and even flaring the hard lines.”

He eventually got the hang of making the lines and got a handle on the fuel leaks, but as Kevin continued figuring out the wiring and other essential items to finish the install he continued to run into roadblocks.


The Pit Crew header was made for a right-hand drive car, meaning the steering shaft interfered and one of the major inspirations for the build was ruled out. Kevin opted for Fujitsubo Legalis R header which was an easy install, but the ITBs and other upgrades were a different story.

“As the parts continued adding up, so did the struggles,” Kevin remembers. Eventually all of the odds and ends made it onto the car, but it still wouldn’t start. I think this is the point in the project that we can all relate to; the moment where you’re on the verge of giving up and can’t see how things could possibly work out.

But in his darkest hour, a hero emerged to saved the day. A friend introduced Kevin to a Chris Allen at Shag Speed who had apparently tuned over 200 Miatas. The Miata master came over and Spirit Road was running that afternoon. “It was like the happiest day of my life,” Kevin says.

The battle was over. It was time for long drives and night cruising for the pair from here out.

Corn’s Collab

But again, no build is ever really complete.


Along the way Kevin purchased some items from Kadin Espinosa — who joined us on our shoot, driving the Miata — from Car Make Corn’s USA. The two enthusiasts shared a lot in common, “so we hatched up an idea to start making Corn’s and Spirit Road jackets, then tool bags, and other items,” Kevin says.


Kevin’s relationship with his little roadster began to take on more hats than he initially expected, and as it sits now Kevin says he has lot of Car Make Corn’s items on his car. “If you didn’t know, you’d think my car is a Corn’s demo car.”


The reason for the marriage between Spirit Road and Corn’s comes from the fact that Corn’s makes a lot of retro-themed items which helped Kevin carry out his vintage vision of ’60s/’70s racer influence. Revlimiter also contributed to Kevin’s build and they later collaborated to make Spirit Road horn buttons, gauge faces, wooden shift knobs, and so on, but as the project expanded Kevin set his sights on a larger item. He decided it was time to build a motor for the car.


“I ran into all kinds of challenges building this motor. A lot of broken promises from different shops, delays, nightmares, headaches,” Kevin says. “No project is ever easy, and I think any gearhead could agree with me. I’ve just been lucky, know a lot of people, and have been fortunate enough for everyone to help and lend a hand when possible.”

His friend Jerry from Jerrybuilt Racing is, in Kevin’s words, a “die-hard Honda drag racer and engine builder,” so Kevin ended up going to him for help with his four cylinder. Over time Kevin began acquiring parts, mentioning that he nearly purchased the entire catalog from Maruha in Japan.


The end result is a 1.9-liter power plant which is good for 154hp at 6,600rpm (and 139ft-lb of torque). Kevin is planning an E85 conversion which will come with a new tune and a redline bumped up to 9,000rpm.

As it sits now with the with the Corn’s 2.5-inch piping and glass-pack muffler, the Miata sounds incredible – take a listen for yourself by hitting the play button above. Complete with a Maruha lightweight flywheel and carbon clutch (and a Maruha 2-way LSD on the way), it’s a proper canyon screamer.


For all of the complexity along the way, the end result is a clean and simple aesthetic, thanks to a Barchetta Clubman GT front bumper finished with Austin Healey bumper lights and R package lip spoilers front and back. The exterior look is finished with a set of limited edition RAYS Volk Racing Murakami-spec MTE37s, but this is only just barely scratching the surface.

It’s impossible to describe in entirety the details this car hides, so a complete and incredibly extensive list of the result of Kevin’s blood, sweat, and tears can be found below. It seems literally nothing was left as it was from the factory, resulting in a car which is practically brand new inside and out.


But why go through months of hair pulling for a car? I think we all have our own answers to this question, but Kevin left us with a quote from Magnus Walker: the goal is to “get out and drive.”

After all, that’s what cars — especially Miatas — are for, right?

Really loving these minimalist builds


Nice. This gives me inspiration with my own Eunos project (a badly treated '94 RS Limited with loads of bits missing and – surprise surprise – some rust), which coincidentally is pretty much the same colour. Jenvey's are on the agenda for that as well, so it's great to see an engine that has been built around them.


Thank you! Hope to inspire ya!


Just lift it 3" and compete with jeeps in mud racing!


I've never seen that front bumper before. It makes the NA look a lot smoother!


That dashboard layout looks FANTASTIC.


Thanks man!


Great article, nice work Sara and Trevor! I love seeing Sara's name on the byline!

This article makes me miss my NA8, I like to think I would have gone this way had I kept it. Beautiful car!




This is an elegant build, with all the emphasis on the right things to make it a great driver's car. Kudos :)


Oh Man, Mr. Woolery! I installed my NA8 header at one of your install days in 2005ish. I also got a ride in your Atom.


Thanks David! Was a pleasure meeting you yesterday evening at Kinod.


Love my 97' Miata special adition...


Wow, that Corn’s Miata is OFF THE COB, yo!!!


off the cobb*


Thank you Sara and Trevor for everything! You two lovebirds definitely made my year! Not just my day! :)


Dude you killed it, maybe buy another and do this!


Love the car, the story, and the addition of your recent posts. The only downside to this car is the lack of power given the amount of mods it has. Coming from an NA Honda background, seeing something fully built with itbs and only making 165hp is pretty low. A bone stock k20a2 makes 165 whp


What matters more is when it comes on and the nearly 50% bump in torque. That's also entirely missing the point of this build. For example a 90s Ford 5.0 makes more power for less money, but no one cares lol...


Thanks Trevor! Just to clarify, the numbers were from a huge roller dyno. Second, we were cut short with the 91 pump gas. Any change left or right of cams, and even at 0 timing engine would shut off on the dyno. We needed to address the fuel issues asap. We also tested back to back Skunk2 Manifold and stock throttle body, and on the same dyno extracted 161 and 136 lbs of torque. With some math conversion and perhaps on a different dyno, we may hit 190+. But then again that is debatable until we are actually able to dyno it again. And we all know how easy it is to get 200+ from a Honda K swap, which we are all familiar coming from Jerry Built Racing. And Trevor is right, that is besides the point. We are trying to push the BP power to the max and stay within the spirit of the Miata. :)


I hear you, but the numbers don't tell the story when it comes to a car like this. It probably has just the right amount of power to be driven foot-to-the floor through the apexes.


Thanks brother.


YES! Love NA Miata's and Kevin's is a rad one. Loved seeing it a JCCS last year where he won the JNC award!


Thanks bud!


I love how well-conceived it looks from every angle, especially the detail work inside. The best part, though, is the way it's not swapped but maximized. It seems like the most satisfying approach to building a car.


Thanks man!


now that's how you mod a car. those retro style bits are way cool.


Legendary is not enough for it.,


Thanks Allan.


Am impressed my 97 na is BRG with tan leather interior after market rims ,stainless steel grill, scuff plates on sills ,roll bar. 123kms on clock needs a repeat to make it look smick




Thanks man!


wow, love the car overall but buying expensive wheels and slapping cheap tires on it is like buying an Armani suit then going to Payless for the shoes. Lame.


Please define "cheap"...:)


All that great work, time and money...then you slap crappy Federal tires on your car? Come on.


You don't like 595's? Enough grip, even for fun on track, without being too sticky and spoiling the fun of road driving. Seems spot on for a light little Miata?


Thanks brother!


Now THIS is some good speedhunters content!!!!


Thanks man.


what's the EO# on those parts?


Never been a Miata guy, but this one just about made me change my mind. Beautiful work.


Thanks mate! Hope I was able to inspire you!


Man! That is so clean! If only I could afford Miatas.


Been following this car on Instagram and it has to be one of my favourites out there.

Only one criticism with the feature - all those images of such a great looking car, and not a single one with the roof down? Soft-top up is so unflattering to the car!


This has got to be the most inspiring car ive seen on speedhunters lately...


Thank you!


Beautiful build man. I've always wanted to do a Cafe Racer / Vintage inspired NA.


Thanks Paul!
