I've found a fallen E12

Yea the running lights are part of the import process.

Well aware, one of my e10s had been hacked up for import.

Someone hacked up the quarters to install running lights ewwwwww

that's what happens when things get grey market imported. it's 100% not surprising.

really? i have passed one or two 635csi's and 735i's up in lkq's over the years. had i wiki'ed it before writing that, i would have found:

1978-1982 E24 635CSi, E12 M535i, E23 735i

i would say 735i's are the common one here.

so.....assuming the i do get my hands on an m90, it says 215hp and 224 ft/lb of torque. what do you do to increase those numbers? i assume if the stroke is short, an m30b35 crank would help. how about an m30b35 head? how about a euro b34 head? what about an s38b36 itb setup?

USDM e23s didn't get M90s.

the entire point of the M90's awesomeness is the short stroke and big bore. it has the same bottom end dimensions as an S38B35. To increase the numbers you need to make it breathe better. E21 intake runners, nice port job on the head (which is basically identical to the B34 head in casting), big throttle body, high compression pistons will give it some power. A modern B35 cam and ignition/injection setup would let you burn a chip and get drivability out of it rather than dicking around with a mechanical distributor. S38 ITBs would be pretty sweet, but a bit overkill on a 12-valve head and a pain to clear the brake booster and coolant distribution block.

are you looking for a race motor? a driving-around motor?

I would save that! Rich knows how expensive and RARE the euro bumpers are, so I would give that it has so many goodies I would low ball then see where he is happy selling at.

Is it just me or are those wheels Epsilon Southern Ways?

[ThatOneEuroE30]

that's going to be a M30B34. You'll have to check the ECU to figure out if it was a green (low comp) or dirty (10:1, nice) B34.

had piano pistons

as a former owner of a production car with an m90 in it, wat

all e12 m535i's came with M90s, as did '78-'81 635csi's.

What about a 84 euro spec m30 out of a 635csi

that's going to be a M30B34. You'll have to check the ECU to figure out if it was a green (low comp) or dirty (10:1, nice) B34.

I still have exhaust manifolds, a distributor cap and an intake boot for that manifold sitting around somewhere that I'd part with. If it hasn't been standing too long we could probably make it run again.

check the trans.

[crappycoco]

The vin of the car said its an 520i (m20). So the engine was swapped with the M30 (i'd rather not get my hopes as high as the M90) in and turbo'd. Hope I can get hold of the guy today.

^since the m90 wasn't offered in a production car, it is pretty unlikely.

[NoM54me]

Sure they were, but not many...think E12 M535i. M88 with an M30 head.

[flyboyx]

Hmmm i wonder if i have a m90 block

That's unequivocally an M30, the valve cover, among other things, gives it away. Besides, the M20's in e12's were carbureted. Almost all e12's are worth saving, especially ones like that. If it was produced for Europe (the EU didn't exist in the late '70's), it's likely a 528i.
