Performance Stats: 1000whp

Some cars arrive in your life by careful planning, a savings account and a lot of spreadsheet browsing. Others turn up on Craigslist when you're really looking for something else. Kevin Tran's 1994 Toyota Supra falls firmly into the second camp, and the way it went from a clean daily driver to a 1000whp monster is exactly the sort of story we love sharing here. It's a 2JZ that was never going to stay standard once its new owner got a taste of boost.

From Ridge Racer to a 1994 Toyota Supra

Kevin describes himself as an adrenaline junkie and car enthusiast, and the origin story is one a lot of us will recognise. Ridge Racer on the Sega Dreamcast, Need for Speed and Gran Turismo on the PlayStation planted the seed, then Import Tuner magazine and Hot Import Nights pulled him properly into the scene. Before the Supra there was a Honda Civic EG hatchback running a B20 with VTEC, a Laguna Blue S2000 and a BMW M4, so he's no stranger to fast cars. Away from the garage he's usually out for a cruise down Pacific Coast Highway in the SUV, hitting the drag strip, going to car meets (the proper kind, not takeovers), fishing, playing poker or catching a concert.

Funnily enough, the 1994 Toyota Supra wasn't even the plan. "Honestly, I wanted an R34 Skyline but could not afford it." Anyone who's looked at R34 GT-R prices lately will feel that one. But luck had other ideas, and a 1994 Toyota Supra popped up on Craigslist. "When I came to see the car I was stunned by the looks and colour." It also came with a handful of mods already done, including an FSR turbo kit running a Precision 6266, a big Brembo brake kit, an upgraded PHR driveshaft and an HKS titanium exhaust. Not a bad starting point at all.

For roughly a year it did daily driver duty exactly like that. Then came the moment every Supra owner sees coming, the point where the 2JZ simply needed more power. Kevin puts it his own way, saying the engine needed more "POWAHHH", and honestly, that's the most honest summary of a thousand horsepower build I've heard.

Building a 1000whp 2JZ: The Engine

Making four figures at the wheels on a 2JZ isn't about one big part, it's about every part behaving. The heart of this setup is a Precision Turbo & Engine 7675 turbo, a serious step up from the 6266 the car arrived with, and it's controlled by a Pro EFI 128 ECU. Inside the block there's a proper rotating assembly, with Diamond Racing forged pistons (86.5mm, which is +0.5mm over stock, at 9.1:1 compression) sitting on Brian Crower H-beam rods. ACL race bearings and thrust washers look after the bottom end, an ARP main stud kit clamps everything down and Real Street Performance billet main caps stop the crank wandering about when the boost really arrives.

Up top, Brian Crower Stage 3 276 cams, valve springs and retainers, GSC valve seals and PHR billet cam gears handle the breathing, and a Hypertune billet valve cover and intake manifold finish the package off. The build was handled by RSperformance, with Ryan Santana building the motor and Beau Brown at BBR Tuning dialling it all in. That pairing matters more than most people admit. A great parts list on a bad tune is just an expensive way to break an engine.

And then there's the fuel. This car runs on E85, which is a big part of how it makes the power safely, but it also means it needs to move a ridiculous amount of fuel. Two Walbro 450lph in-tank pumps sit alongside a PHR triple Walbro 485lph pump hanger, backed by a PHR dual pump harness, Bosch 2000 injectors, a PHR -8AN high flow fuel rail and an Aeromotive A1000 regulator. An AEM ethanol content flex fuel sensor kit keeps the ECU informed about what's actually in the tank. Joe at JR Race Wiring did the fuel system, and the custom engine race harness came from Kaizen Motorsports.

Keeping a 1000whp Supra Cool, Connected and Drivable

Big power creates big heat, so the supporting cast matters. A Mishimoto aluminium radiator and hoses help the cooling side, a PHR XTM catch can keeps the breather system in check and the intercooler and all of the piping were fabricated by Ryan at Humble Engineering. On a 1994 Toyota Supra making this sort of power, a custom intercooler setup isn't just about fitment. It's about getting the air to the engine as cold and as direct as possible, and a tidy fabricated install is a big part of why the whole car looks as purposeful as it does.

The drivetrain carries a Titan Motorsports (ATI) damped crank pulley, PHR aluminium pulleys, a Gates Racing timing belt and a Titan billet tensioner bracket. The clutch side is an FX1000 heavy street twin disc setup with a steel flywheel, and a SuckerPunch short shifter makes every gear change feel a bit more like you mean it. Kevin does admit the next sensible upgrade is a limited slip differential, and with a thousand wheel horsepower going through the rear, he's right.

Chassis, Brakes and Wheels

On a 1994 Toyota Supra that spends its life being launched at the drag strip, the handling and stopping side has to keep up. The suspension is HKS Hipermax IV GT coilovers, which have long been one of the go-to choices for people who want a proper coilover without turning the car into a go-kart on the road. Titan Motorsports sway bars sit at both ends, with SuperPro endlinks, and SuperPro poly bushings throughout the front and rear control arms keep everything tight and predictable.

For stopping power, the Brembo big brake kit that came with the car is a six piston setup up front, paired with StopTech stainless brake lines for a firm pedal. The wheels are an interesting mix, with Forgestar F14s on the front and Welds RTS S71 15 inch rears, the sort of combo you only really see on cars built around straight line pace.

Exterior and Interior of the 1994 Toyota Supra

Visually this 1994 Toyota Supra keeps things clean, which is the right call for a car with this much going on underneath. Brand new 98-spec headlights and turn signals freshen up the front end, a Seibon TRD carbon fibre hood adds a bit of weight saving and a lot of attitude, and the HKS titanium race exhaust provides the soundtrack. Its flame show is one of the first things Kevin mentions, and if you've ever heard a big single turbo 2JZ shoot fire out of a titanium exhaust on a gear change, you'll understand why.

Inside, the cabin has been kept driver focused. Recaro Evo Mr front seats hold you in place, a personal Alcantara Nardi steering wheel with a Works Bell hub sits in front of you and the rest is wrapped around a very 90s Supra cockpit layout. There's still a bit of daily driver DNA in there too, with a Viper alarm with remote start, a Kenwood four DIN head unit and a 10 inch Kicker sub in case you need a bit of music between boost.

Why This 1994 Toyota Supra Feels So Special

Ask Kevin what makes his car unique and the answer has nothing to do with the spec sheet. "When I was young I would have never thought I could own a true classic of this calibre, an iconic JDM legend." From the driver's seat he describes it as sitting in a jet cockpit with everything pointed at you. "I step on the gas and get on boost, you get sucked into the driver seat and the pull is non-stop." Anyone who's been in a properly built 2JZ car will know exactly what he means, that moment when the turbo spools through the gears and the world suddenly gets a lot narrower.

The best thing about this 1994 Toyota Supra is how Kevin talks about the reaction outside the car. "When I take the car out, you really feel the love and appreciation for it." Strangers give thumbs up, people honk, someone yells "nice car!" and that's the real reward of owning one of these. The MK4 Supra has a way of crossing generations, and Kevin sums it up neatly by calling it an inspiration to the old and new generations alike. If you want more of that kind of culture, the Stance Auto Magazine store on Amazon has plenty to feed the habit.

What's Next for the 1994 Toyota Supra

You'd expect the future plans for a 1000whp Supra to be wild. Instead, Kevin keeps it refreshingly grounded. A fresh paint job and a proper LSD are on the wishlist, but right now his focus is simply on enjoying the car without getting pulled over. Fair enough. When your 1994 Toyota Supra makes this much power and spits flames, the best plan really might be to enjoy it and keep one eye on the mirrors.

A huge thank you goes out to everyone involved in the build, including Ryan Santana at RSperformance (@rsperformance_shop), Beau Brown at BBR Tuning (@bbrtuning), Ryan at Humble Engineering (@humble_engineering), Kaizen Motorsports (@kaizen_motorsports) and Joe at JR Race Wiring (@jr_race_wiring).
