Hi guys

Ive recently brought what I think is a m50b25 off trademe

can anyone confirm that it is a 2.5L and not a 2.0L

Ive tried searching the net but the block numbers dont make sence

ecu numbers

bosch motronic

0261200402

wbac22010fa <--- sounds like a chassis number but cant decode it

06547

07797/07797

1744773

block numbers

33920058

20 6 s 1 <-- tells me its a 2.0L 6cyl

25c91 <-- cast into block

1735813 <-- also in block

head number

2.0

1720901

I just want to confirm it is what it is before I go back to the seller

Realy dont want to waste my time fitting it to my e30

thanks

Jeremy

FA06547 belongs to a 02/1992 manufactured E36 saloon RHD auto 320i, European. Looks like the ECU has been swapped at some stage........

Funny you say that. This is a picture of my spare engine.

It came from an E34, but it has E36 stamped on it. Was auto. I am almost 100% sure it is a b25, I will measure the bore later on when I get home.

I have another M50, I will post the block numbers of if you would like to look those up aswell, as I am 150% sure it is a b25.

Edit: Just measured, it is 84mm so definatly b25.

Edit2: NVM, I see you just quoted the wrong post, as the block numbers you posted to not match my block, but match the OP's

^let us know how you get on.

gutted to hear that man, if the seller sold it to you as a 2.5 then the balls in their court as far as liability goes, even if it was a genuine mistake on their part. i hope you bought it locally, then the whole process of returning the engine and getting your money back shouldnt be too much of a faff. if they aren't cooperating then take it to the disputes tribunal, it'l be a very open and shut case for them. hope it all goes smoothly for you and you can get your car finished quickly, nz needs more e30m50s!

I think I used e34 m20 mounts, grind the location tab off them and they fit great.
