Take a 2020 Toyota GR Supra,already a performance icon in its own right. Now rip out the stock turbocharged inline-six and replace it with a screaming, fire-breathing Judd GV4 V10. Yes, the same 4.0-liter engine once howling on Formula 1 circuits. That’s exactly what drift veteran Ryan Tuerck pulled off, and the result is nothing short of wild.
This isn’t your average engine swap. The Judd GV4 is a motorsport legend—a naturally aspirated V10 revving to an insane 11,000 RPM, pumping out 730 to 750 horsepower. It completely changes the car’s character. While it weighs a bit more than the original B58 (around 320 pounds), the powerband and the sound more than make up for it. The exhaust note alone rivals the Lexus LFA’s — sharp, raw, and loud enough to raise goosebumps mid-drift.
Power is sent through a 6-speed sequential gearbox, offering lightning-fast, mechanical shifts that feel like something from a touring car paddock. Everything about it screams race machine, down to the way it blips and bangs through the revs.
More Than Just a Loud Engine
Dropping a V10 into a Supra wasn’t the end goal — it was just the beginning. The entire chassis needed serious reinforcement. Tuerck’s team fitted custom subframes, a reinforced differential, and reworked the suspension geometry to withstand the Judd’s brutal torque and the abuse of full-lock drifting.
The car also went on a dramatic weight-loss program. Stripped to the essentials and rebuilt with lightweight materials, the Formula Supra now weighs just around 2,500 pounds, shedding over 870 pounds from its original form. That weight-to-power ratio? Borderline absurd — in the best way possible.
Add side-exit exhausts blasting that V10 symphony into your ears, and you’ve got a rolling experience that’s as loud as it is lethal.
One Platform, Endless Possibilities
What sets this build apart is its flexibility. It’s not built for just one thing — it excels across disciplines:
- Drifting? Obviously. It’s built to slide and smoke tires in style.
- Time attack? It’s got the aero, grip, and balance to chase serious lap times.
- Hill climbs? With that weight and gearing? Point it uphill and hang on.
It’s rare to see a car that feels just as at home sideways at 100 mph as it does clipping apexes or flying through switchbacks.
The Formula Supra is more than just a wild custom project. It’s a challenge to conventional thinking — proof that with enough passion and technical know-how, even the most outrageous ideas can come to life. Fitting a Formula 1-derived V10 into Toyota’s modern sports car isn’t just about making noise or headlines. It’s about engineering freedom, pushing limits, and creating something truly one of a kind.
If you love drifting, high-revving madness, or just beautifully built machines that make no apologies, this is the Supra that breaks all the rules.
