The Toyota Supra has become a tuner icon, mainly because of the legendary tuning ability of the 2JZ-GTE engine used in the top-ranking A80 (Mk 4) cars. Toyota's flagship performance engine was a twin-turbo straight-six that builders quickly learned was strong enough to be tuned to make crazy amounts of power. The new fifth-generation Toyota Supra initially shipped with a turbocharged straight-six engine as the only option, but BMW builds this one. Like the 2JZ engine, though, tuners have realized it's just as strong as the 2JZ and can take plenty more power.

We're already starting to see 10-second modern Supras, as well as Supras built to do more than drive fast in a straight line. It's still early days for the new Supra as it's only in its second year of production, but these are our favorite builds so far. Plus, of course, a classic MK IV Supra build to remind us just how far tuners can take a Supra.

Speedy Mufflers & Performance Nine-Second Supra

The BMW B58 engine that sits under the hood of the new Supra is strong, capable, and takes to modification exceptionally well. In October last year, Puerto Rico-based shop Speedy Mufflers & Performance made some adjustments, bolted on some Hoosier radial drag tires, and laid down a nine-second quarter-mile time.

It wasn't exactly as simple as that, as they made use of a lot of tuning skills and some extra equipment. The car had a nitrous oxide system installed, a new exhaust system, and ran on 100-octane fuel. The quarter-mile run was clocked at 9.9244 seconds with a speed of 133.4507 mph.

Toyota GR Supra Drift By HKS

Some fans of the 2JZ-powered Supra can't let go, so Japanese aftermarket specialists HKS replaced the BMW B58 power plant with a Toyota 2JZ-GTE engine in its showcase drift car. However, it's not a stock lump. After being bored out to 3.4 liters and getting a bigger turbo, it now makes 690 horsepower and 620 lb-ft of torque. It's a competition-level drift car, and, along with the gratuitous extra aero, it also features race-spec brakes, Hipermax SPL suspension, and rides on Advan wheels wrapped in Advan tires.

Toyota GR Supra GT500

Meet one of the most extreme Supra models yet. The Supra GT500 follows in a long line of Toyota competitors in Japan's highly competitive Super GT racing series. To meet class rules, Supra GT500 does away with the straight-six engine in favor of a 2.0-liter turbo-four. It's hardly a downgrade, though, as the new engine makes around 670 hp in readiness to go up against the Nissan GT-R and Acura NSX. Unfortunately, the new season Super GT is delayed, so we're still waiting to see the race car built shelled in bare carbon and with crazy aero in action.

The Stradman's Extremest Widebody Supra GR

This eye-popping machine is the opposite of a race car, and falls firmly in the show car camp. It belongs to a YouTuber known as The Stradman, and the extreme looks come from a widebody kit from a company called Pandem. It includes revised side skirts, a new ducktail spoiler, and a monster of a rear wing that wouldn't be out of place on a Need For Speed video game car. It sits on an Accuair suspension system, and a custom-colored set of SKÖL SK3 forged wheels measuring 20x10 inches at the front and 20x12 inches at the back.

2020 Rockstar Energy Drink Toyota GR Supra

Not long after the Supra GR was released in the wild, master engine builder Stephan Papadakis made a video showing a teardown of the BMW B58. He noted and explained its potential, then, following the video, he set about tripling the engine's power for a drift car. From the factory, the BMW engine makes 335 hp and 365 lb-ft of torque. Now, the drift Supra is pushing 1033 hp and 908 ft-lb of torque with some help from Papadakis Racing's partners. The engine is just one component of a drift car, and it's been built from the ground up to compete in the Formula Drift Championship with Fredric Aasbo at the wheel.

LL17 Motorsports GR Supra HyperBoost Edition

Last year's SEMA show saw a slew of built Supras on the show floor. One of them was the GR Supra HyperBoost Edition. Toyota was behind this one and contacted the former host of American Top Gear and current NASCAR analyst, Rutledge Wood. The automaker knew Wood is a fan of the Supra, and he worked with lead builder LL17 Motorsports to come up with something special. The HyperBoost Edition features a 20-piece carbon-fiber widebody kit, a carbon-fiber roof, KW Automotive V3 adjustable coilovers, and 20-inch Lightspeed Racing wheels with carbon-fiber rims. LL17 also brought in Boost Logic to crank the BMW B58 engine up to 750 hp, making it as aggressive and powerful as it looks.

NATS Convertible Supra Mashup

When it comes to crazy Supra's, this offering from Nihon Automobile College (NATS) in Japan is one of our favorites. Technically, it's not a Supra, though, as it's built upon a Lexus SC chassis. It's also a convertible, which is not currently part of the fifth-generation Supra from which the body panels come from. Muddying the water even more, it has a 2JZ engine under the hood. The mashup car is reported to make over 600 hp, and the color scheme and decals are a little more than reminiscent of Brian's Supra from the first Fast and Furious movie. Oh, and it has Lamborghini style scissor doors.

Top Secret V12 Toyota Supra IV

We'll finish this list with a piece of tuner history. By day in the early 1990s, Kazuhiko "Smokey" Nagata worked for an aftermarket parts company. By night, he created his own parts for his cars and took on work for others. Eventually, he turned his extracurricular work into a company called Top Secret. Nagata's V12 Toyota Supra, along with his penchant for crazy driving and run-ins with the law, cemented his place in tuner lore. In 1998, he pulled the 5.0-liter V12 1GZ-FE engine out of a Toyota Century and put it in his MK IV Supra. The Century engine made less power than the straight-six that came out but had more potential. A pair of HKS GT2835 ball bearing turbochargers and a wet nitrous setup help generate 930 hp and 745 lb-ft of torque. He also made use of Top Secret's Super G-Force kit and an adjustable suspension setup.

Nagata wanted to crack 200 mph with the car, and after spending some time in jail in the UK due to his first attempt, he hit 222.6 mph in Italy in 2008.
