The opposite: unbadged: BMW E30 320is:
"What makes the E30 320is unique?
The E30 320is is a special 3 Series model that was sold exclusively in Italy and Portugal in order to take advantage of the reduced taxes in those countries for cars with engines that displace two liters or less. It is powered by a 1990cc version of the four-cylinder S14 engine developed by BMW Motorsport for the E30 M3 and also shares its close-ratio Getrag gearbox with the M3. However, all other components are standard 3 Series items.

If the E30 320is is powered by an M engine, why is not badged as an M model?
The reason the E30 320is is not badged as an M model ultimately comes down to marketing: Unlike the limited-production M3, which was created primarily as a competition machine and utilizes many unique exterior body panels and chassis components, the 320is was never intended to be a homologation special. It was conceived instead as a sportier and more affordable alternative to the torquier and more refined 325i, which was taxed heavily in Italy and Portugal due to its 2.5-liter engine.

What makes the two-liter S14 engine unique?
The two-liter S14 engine in the E30 320is is essentially identical to the 2,302cc version found in the E30 M3 except for its shorter stroke (72.6mm versus 84mm) that yields an overall displacement of 1,990cc. Like all S14 engines, it combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments.
The two-liter S14 is rated at 192 hp (DIN) at 6,900 rpm and 155 lb/ft of torque at 4,900 rpm. This is down slightly compared to the non-catalyst, 2.3-liter S14 used in the E30 M3 which is rated at 200 hp (DIN) at 6,750 and 176 lb/ft of torque at 4,750 rpm.
The S14 engine fitted to the 320is has an identical appearance to the unit found in the E30 M3 and thus shares the "BMW M Power" inscription on its cam cover."
