The BMW 2002 is one of the German automaker’s most coveted vehicles, but what if its stock capabilities aren’t enough for you? One 2002 owner swapped a turbocharged Honda F-Series motor into it. The car is for sale, but are its newfound upgrades enough to justify what some might consider a sacrilegious engine swap?

The 1976 BMW 2002 is listed for sale on Bring A Trailer, where its Honda-sourced odometer reads 109,000 miles (175,418 km), although the seller claims the total mileage is unknown. The car was purchased by California-based tuning shop CATuned in 2010, where it had many of its modifications (including the new engine) installed, and it was given a turbocharger after being purchased by the current seller in 2014.

The exterior was refinished to its current red paint, which has faded a bit over the years. The car rides on silver 15-inch Rota wheels mounted on 195/55 Michelin Premier A/S tires, behind which are a set of Wilwood disc brakes with slotted front rotors and an E21 3-Series dual-piston master cylinder. Stance is provided by a set of coilovers with adjustable camber plates at the front, and Bilstein rear shocks with Ireland Engineering sway bars at the rear.

Inside, the car features tan-upholstered Recaro sport seats and door panels from an E21, and a 15-inch Alpina steering wheel frames a Honda S2000 gauge cluster. Additional equipment includes an AEM boost gauge, an AEM air-fuel ratio gauge, and a Pioneer CD stereo head unit. The lower parts of the interior remain unfinished because the seller wanted to make it a good driver’s car first before worrying about the aesthetics, but pushback from his wife on the project caused the latter to come to a halt.

Finally we get to this car’s standout modification: its engine. Under the hood is a 2.0-liter Honda F20C inline-four with a ceramic-coated Garrett GTX2867 turbocharger bolted to it, and additional modifications include custom headers, a downpipe with a race catalytic converter, and an AEM Series 2 engine-management system. A dyno sheet included with the purchase rates the car at 275 hp (279 PS / 205 kW) and 182 lb-ft (247 Nm) of torque, which is sent to the rear wheels through a six-speed manual transmission and a limited-slip differential.

That’s significantly more than anything this car was making when it was new, but would it be considered heresy to put a Honda engine in a BMW, especially one with as much heritage as the 2002? Let us know what you think in the comments.
