95 euro m3 vs 95 us m3

[95m3driva]

i know the euro 95 m3 puts out about 40-50 more horses but why, what is different about engines!!!! ghead ghead ghead

[CiscoKid]

pretty sure it has something to do with emissions

[dutchbmw]

Euro M3 engines are made by the BMW Motorsport department, US M3 engines in the normal factory. Don't know the exact differences.

[95m3driva]

well if the euro's are made by the motorsport department, what do they do different to the engine beside the double vanos? Does the euro have different cylinder compression, higher performance cams? WHAT IS DIFFERENCE!?

[dutchbmw]

I am not sure but I guess the air intake part is different and maybe other camshafts are installed. In NA are also more restrictions (emissions) and that should be a reason too.

[e36_m3_Turbo]

HFM, intake manifold, ECU just ot name a few

[MrM3]

they use different engines. its not like the US motor is a de-tuned or restricted version of the european spec engine

[95m3driva]

besides the head is, the euro block and block internals are they the same as the na block, because what i am trying to get at is that can you convert a us to a euro by changing head and ecu

[Fox]

Compression, combustion surface design, True M intake manifold multi throttle, entire different exhaust, OBD 1, different head design, different block, different cam profile, yada yada yada.

Yeah, the two engines aren't even comparable.

They're totally different, nothing is really interchangable when it comes to the engine itself. The exhaust is interchangable.

The US spec m3 engine has more in common with a 325 or 328 engine then it has with a euro M3 engine.

The euro engine can also rev higher, has oil jets shooting oil under the pistons to cool them..

Both the 95 US and the 94-95 Euro engines are OBD1 though.

There was a run of 45 94 euro m3's imported into Canada by BMW though.

Also, in 96 the engine had more displacement, and more hp (321hp, versus 284hp)

Don't forget that in Europe they have to pass emmisions test also, they're just not as strict as they are in California, or most of North America for that matter.

So in 96, the Euro Spec engine got an engine boost to 320?
How hard is it to an engine swap with a 96 engine and a 96 usdm m3?

Well, all you'd really need is the engine, the ECU, and the wiring harness.

The hardest part would be opening your wallet to pay for it. Euro engines aren't exactly cheap. Probably cheaper to just get forced induction, and get more gains.

Here in my living area there is a salvageyard with only BMW, and also M3 engines. I have asked the owner a while ago about prices. He said that I should pay €3,000 (Euro) for an M3 from '96 (321 HP). This is about $3,540. The total costs came on €5,000 (Euro). This including wiring, drivetrain, ECU and suspension with brakes!

I'll send it for you if you want some.......
