polley 916 Report post Posted April 21, 2011 (edited) 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 Edited April 21, 2011 by polley Quote Share this post Link to post Share on other sites

w_elliot 7 Report post Posted April 21, 2011 (edited) 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!
