4.4 into e34??

[bimmer630]

Is it possible to directly replace a 3 liter V 8? with a 4.4 non vanos? Vehicle in question is a 95 530 I

[goarmy]

Put the question in hand to the V8 section of the forrum.

[slammin.e28]

Yes.

4.0 is a direct swap, just swap the ecu.

Don't see why running a 4.4 on OBD1 would be that much more difficult.

[Vtec?lol]

if you change over the timing chain and covers it'll run off the factory DME I believe. I think you'll need to use the heads off you 3.0 as well

[iamsam]

Are M60B30 and M60B40 heads the same?

[Jean]

the m60 4.0 is basically plug and play, but 4.4 isn't.

You'll need to convert the m62 4.4 to obd1 to run in the e34, or make a hybrid m62 using parts from the 4.0 m60.

3.0 m60 intake/throttle/heads/valves are different from the 4.0

3.0 and 4.0 share the same oil pans/timing covers upper and lower, but the internals are not the same, cams are though.

example -

3.0 cams on the 3.0 and 4.0
11311736117 on the 4.0 = 11311736117
11311736131 on the 4.0 = 11311736131
11311736119 on the 4.0 11311736119
11311736133 on the 4.0 11311736133

intake valve 32,0/5.94 11341435476 on the 4.0 35/5.94mm 11341435480
exhaust valve 28.5/5.94 11341435478 on the 4.0 30.5/5.94 11341435482

lower timing cover 11141733522 / on the 4.0 = 11141733522
upper covers 11141729583 / 11141729585 / on the 4.0 11141729583 / 11141729585

head 11121731912 / 11121731913 on the 4.0 = 11121731910 / 11121731911


Obviously 4.4 cams are totally different as well, along with the heads too.
