A thread briefly discussing differences, but there should be better ones.

Located by Edgy:

How did the U.S.-spec version of the E36 M3 come about?
When the E36 M3 made its European debut in 1992 there were no plans to produce a North American version. Sales of the previous M3, the E30 of 1988-91, had amounted to just under 5,000 units and BMWs only other North American-spec M car at the time, the E34 M5, was not selling in large enough quantities to justify the addition of another M model in the American market. However, a letter-writing campaign initiated by the BMW Car Club of America sparked such an overwhelming response by the enthusiast BMW community that BMW of North America decided to reconsider. The main issue was price: BMW NA was determined to keep the MSRP down to around $35,000, about the same as the last of the E30 M3s. The only way to meet this price point was to develop a specific version of the S50 engine without the costly individual throttle bodies and continuously variable VANOS valve timing system of the European-spec motor. Just such a car entered production in February, 1994 (as a 1995 model) and went on to be produced in almost equal numbers to the European version despite a production run of only half as many years. (Note: This model was not available in Canada see question below)

This more or less covers everything engine related I think.

I can't seem to find any stuff prior to moving forums, so I'll just post what I know.

Pretty much, Euro M3's have all the engine differences that we talked about before, but they have some cosmetic stuff too.

For instance, US headlights are notoriously bad. They are cheap plastic that illuminate like 20 ft. in front of you. People buy the EURO headlights because they're made of glass and use projector lenses. Though they are still halogens, they are way better. Umnitza, one of our beloved sponsors :) sells euro lights if you need them.

Euro M3's mostly come with clear corners, side markers, and tailights too, but I'm sure on that one. Somone suggested that the bumpers are slightly smaller and better contoured as well, but don't quote me.

They have an adjustable steering column, which I would really really want.

They have a 6 sp tranny instead of our 5. Our 5 speed is really just their 6 without a 6th gear which is why we are always revving so high on the highway.

They had available SMG I, but I don't know what years that was available in. The US model didn't have that option until it was SMG II in 2002 for E46 M3's.

Ummm...I'm sure I'm missing a lot of stuff here. Anyone else?

Aluminum hoods and doors I believe - on the Euro's.

Oh, and the rotors on the euros are a "floating" design and much better for heavy track use.

I don't know how I forgot that one.

"Our 5 speed is really just their 6 without a 6th gear "

Then why won't the Euro tranny fit on the NA?

If we want to be totally comprehensive, note the first gen Euro had an S50 engine that put out 286 HP, while the 95 NA version had same designation, but only 240HP.

For 96-99, US engine gets it's own designation, S52, and a little more torque.


How is the Euro-spec M3's 3.2-liter engine (S50 B32) different from the previous version (S50 B30)?
When creating the 3.2-liter M3 engine, BMW M relied upon much of the experience it had gained when designing the V12 engine for the McLaren F1 supercar. In the end, the S50 B32 incorporated the following improvements over the S50 B30 engine used in the original Euro-spec E36 M3:
-Increased bore to 86.4mm (from 86.0mm) and lengthened stroke to 91.0mm (from 85.8mm) for a total capacity of 3,201cc (from 2,990cc)
-Increased compression ratio to 11.3:1 (from 10.8:1)
-Advanced BMW/Siemens MSS50 engine management system able to compute 20 million instructions per second
-Double VANOS continuously variable valve timing on both intake and exhaust strokes
-Lightweight pistons
-Improved dual-mass flywheel
-Graphite-coated conrods
-Larger inlet valves
-More efficient intake and exhaust systems
-Second oil pump

The result of these changes boosted horsepower from 286 hp (DIN) at 7,000 rpm to 321 hp (DIN) at 7,400 rpm. Maximum torque also increased from 236 lb/ft at 3,600 rpm to 258 lb/ft at 3,250 rpm. This was the first street-legal BMW engine to achieve over 100 hp per liter.

How is the North American 3.2-liter M3 engine (S52) different from the 3.0-liter (S50 B30 USA)?
Unlke the Euro-spec S50 B32, the S52 powerplant is an evolution of the standard production M52 engine. However, it incorporates the following changes over its S50 B30 USA predecessor:
-Increased bore to 86.4mm (from 86.0mm) and increased stroke to 89.6mm (from 85.8mm) for a total displacement of 3,152cc (from 2,990cc)
-More finely balanced camshafts
-Valve lifters, springs and spring seats with reduced mass
-Revised intake and exhaust systems
-OBD II (On-Board Diagnostics, version II) compliance
-Horsepower unchanged at 240 hp (SAE) at 6,000 rpm
-Torque increased to 236 lb/ft at 3,800 rpm (up from 225 lb/ft at 4,250 rpm)
NOTE: E36 M3s equipped with the ZF five-speed automatic transmission are rated at 225 lb/ft of torque at 3,800rpm.




The E36 M3 3.0 is the original BMW Motorsport (later called BMW M) version of the E36 3 Series. Available as a coupe, convertible or sedan, it uses one of two 3.0-liter S50 engines, both based to some degree on the standard production M50 powerplant. The European S50 has individual throttle bodies and a more complex cylinder head, while the U.S.-spec S50 more closely resembles the normal production M50 engine. All E36 M3s also have a BMW M-tuned chassis and unique cosmetic items both inside and out. Unlike its E30 M3 predecessor, the E36 M3 was not designed primarily for competition use, but rather as a road-going GT car.

Good point Extrav. I heard that the ratios were the same for 1-5 though pretty much.

Wow, we're getting good stuff! Keep em' coming.

"Our 5 speed is really just their 6 without a 6th gear "

Then why won't the Euro tranny fit on the NA?

Who said it doesn't fit? It bolts up fine.

You do need a shortened driveshaft. You can buy a euro one, or shorten your stock driveshaft.
