Trivia Question: Was the s14 the only motor used in only one chassie by bmw?

[george graves]

Or has BMW made other motors that were chassis specific? (in other words - the basic motor(m10, m20, m30, m50, m70, ect)... seen only in one body type style (e12, e21, e30, e31, e36, e46, ect...)

I actually don't know the answer!

M10: 2002, e21, ...
M20: e28 and e30's, ...
M30: e12, e24, e28, ...
M50/S50: e36, e34, ...

So that rules out most of your run of the mill motors.

What about the S62 E39 only? S54 E46 only? Newer ones seem more frequent...

Wasn't s54 in m coupe the last year the made them. I believe it was 2000? Not positive on the year but I know the last year they ran s54's instead of s52's

And the z4 m coupe

Obviously there's the new ones but I supposed they don't count, e60 m5 and e92 m3, 760il

What about the 850CSI? I don't know what was in that. And that old turbo 7, whatever it was

EDIT: Apparently the s70b56 was in the 850csi, only car with that engine. Also interesting, the mclaren f1 used a variation of the m70 that is similar to an s50b30

[Anthrax]

No, there was a couple of different versions of the s70.

E21's got M20's too...just not here in the US.

BMW fitted an S14 in an E36 racecar before but that wasn't a production model. It was either an S14 or S42, not sure which. So, yeah the S14 was E30 specific...E30 M3 and Italian 320iS.

[rs4pro3]

the 745i engine was an m106 and m102 block, but basically a m30 block with some minor changes and oil squirters(in some years), and also a very trouble prone engine. http://en.wikipedia.org/wiki/BMW_M106

And the e36 got the s42

there are quit a few of those specialty engines out there that gone there own code, and were just found in one chassis

[Raxe]

S62 was in the E39 M5 and the Z8.
M20 was in the E34 as well.
S54 was in the E46 M3 and new Z4M.

[Jon325i]

Don't forget the 1 and 2 cylinder powerhouse Isetta motors :-P

[uofom3]

s14 was run in some early e36 race cars and test mules wasn't it?

That was the S42. Johnny Cecotto drove that car for a while.

Most likely, but not in any other sold production cars. I'd forgotten about the 320is until Barry mentioned it.

s54 was in m-coupe until 2002. Check out Atan888's on s14.net.
