The BMW M3 E30 stands poised on the horizon of modifications, powered by a robust 3.5-liter turbocharged inline-six from an Alpina B7 S Turbo.
In the past decade, the E30-generation BMW M3 has emerged as a sought-after collector’s car. Despite its rising value, Manhart took the bold step to enhance the E30 M3, increasing both its speed and visual appeal.
The transformation starts with a significant engine upgrade. Replacing the original 2.3-liter naturally-aspirated four-cylinder, Manhart installed an engine previously housed in an Alpina B7 S Turbo—the turbocharged 3.5-liter inline-six. In its Alpina form, this powerplant boasted 330 HP and 369 lb-ft of torque. Eager for even more power, Manhart revamped the turbocharger and intercooler, pushing the engine to an impressive 405 hp and 479 lb-ft.
Mated to the new engine is a five-speed manual transmission and a Drexler differential, driving the rear wheels. Although no official performance times have been released by the tuner, considering that a standard E30 M3 weighs just over 2,500 lbs (~1,133 kg), it's plausible that this modified version could rival the performance of a current M3.
Manhart didn't stop at the engine. The vehicle is now equipped with a resonant exhaust system, and braking capabilities were enhanced to match its acceleration. H&R coilovers were installed to lower the ride height and sharpen cornering, paired with new four-piston Brembo calipers up front, biting down on drilled 330 x 32 mm discs.
The curtain of modifications is drawn with exterior and interior refinements. The car's dark matte green paint complements the stunning Concave One Manhart wheels, measuring 19x8.5 in the front and 19x9.5 at the rear. Inside the cockpit, Cardinal Red seats, a Momo sport steering wheel, and a new digital display—replacing one of the original air vents—complete this compelling transformation.
