Five niche cars prove you can mount motorcycle engines in four-wheeled bodies, delivering extreme revs and razor-light weights: Morgan 3-Wheeler, Ariel Atom V8, Radical SR1 XXR/SR3 XXR, Caterham Seven, and Honda N600, each tuned to maximize torque and acceleration in tiny, high-revving packages.
Volkswagen marks the 50th anniversary of the GTI by reviving its wild Mk5-era W12 concept—the GTI W12-650. Powered by a mid-mounted 6.0-liter twin-turbo W12 from Bentley and sending about 640 hp to the rear wheels, it borrowed parts from Audi, Lamborghini, and even a Phaeton transmission to create a rare, high-strung showpiece. Designed more as a celebration than a production model, the W12-650 remains a temperamental legend of VW Group’s extreme engineering ambitions.
Ford upgraded the 428 to the Cobra Jet in 1968, using a Police Interceptor block, 427 heads, a performance cam, and a Holley 735 CFM carb to produce about 335 hp and 440 lb-ft (with many experts arguing closer to 400 hp). Ford then injected the CJ into a broad lineup—Mustang GT/135, Mach 1, Fairlane, Torino GT, Cobra, Shelby GT500, Mercury Cougar variants, Comet, and Cyclone CJ—often with performance options like Drag Pack and Ram Air, creating a legendarily versatile big-block era aimed at beating rivals on the street and strip.
The article compares Honda's 2.0L K20 and 2.4L K24 engines, noting the K24 increases bore to 87 mm and stroke to 99 mm (raising displacement and deck height) with only about a 9 lb weight gain. Factory power ranges span roughly 156–316 hp for K20 variants (with the turbocharged K20C1 reaching 316 hp) and 160–206 hp for K24 variants (e.g., 206 hp in some). Tuning potential is high: K20s have safely surpassed 1,000 hp with stock crank and up to ~1,400 hp with upgrades, while turbocharged K24s can reach ~500 hp in stock form and up to ~1,600 hp with strengthened components. The K-series’ abundant parts and aftermarket support help fuel widespread swaps into many cars, including non-Hondas, making them a popular choice for performance upgrades.
