We're still mourning the loss of the Ford Focus ST and Fiesta ST. Since being discontinued for the US market, both cars have left a huge hot-hatch void in Ford's model lineup that has yet to be filled. Ford still sells the Mustang to satisfy performance car enthusiasts, but the Focus ST and Fiesta ST were cheaper and more practical, yet gloriously fun to drive.

Happily, aftermarket tuners are continuing the legacy of Ford's ST line. We've seen plenty of modified Focus STs with sportier styling and more power to play with, but this project by JD Customs transforms the Focus ST into a completely different animal. Pop open the hood, and you won't find the 252-hp 2.0-liter turbo inline-four engine that powers the standard Focus ST.

Instead, JD Customs has stuffed a Whipple supercharged Coyote V8 from a Ford Mustang. JD Customs hasn't released any power figures, but Whipple's stage 1 Gen5 supercharger kit generates 650 hp on the dyno. Considering it weighs a lot less than the Mustang, this modified Focus ST's performance should be mind-blowing.

And no, all that power isn't being sent to the front wheels like the standard car setup because JD Customs has turned the Focus ST into a rear-wheel-drive hot hatch. You have to commend the amount of work and engineering that must have gone into this ambitious project.

The modifications don't end there either as the tuner has aggressively customized the exterior with front and rear wider fenders, a custom front grille, and a massive rear wing.

Lowered suspension also brings the rear-wheel-drive Focus ST closer to the ground. Combined with a black exterior and orange accents, this heavily modified Focus ST looks suitably menacing compared to the standard car.

The black and orange theme continues inside, where you'll find an orange roll cage, Alcantara and leather seats with orange stitching, custom trim for the door panels and dashboard, and a Mustang steering wheel. Orange and carbon fiber accents are also applied throughout the interior. JD Customs has been testing its creation on the track, so hopefully, it won't be long until we get to see it in action on video.
