I've found a fallen E12

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

Someone hacked up the quarters to install running lights ewwwwww


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.

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?

Yea the running lights are part of the import process.

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

[NoM54me]

No B35 head. They have different coolant passages than other M30's, your cylinders would fill with coolant.

Personally done mind them. Keeping them on my euro spec.

that's completely false.

it will, however, dump your compression ratio way down.

how do cars like this end up sitting for decades?

subscribed.
I wanna see this go places.

thats good info thar! i just want a driving around motor. more torque than rpm would be ideal.

i'm sure there must be a thread on it if i searched, but i was just wondering what is the best naturally aspirated combination for an m30? best torque/hp without spending ridiculous money on custom parts?

[kronus]

M30B35, mark D chip, single mass flywheel, done.

[Motorsport maniac]

Is there a special way of identifying m90 blocks

[crappycoco]

Supposedly there is a white "L" marked behind the oil filter. Pls confirm =)

[kronus]

see the long square that ends in a freeze plug that goes down the middle of the block? that's what it looks like on an M90. On a regular M30 it's a lot shorter.

(it's a coolant passage)

there's typically an L drawn on it, but good luck seeing it under the dirt and rust on a typical engine.

[ThatOneEuroE30]

I don't think I have a m90 :( Owell though I'll still have one hell of a turbo motor.
