    Hello I bought a 325 (m50b25) and I was planning to fully swap it with my 323( m52b25) - OBD2 to OBD1. I already did a compression test on the m50 and I'm quite satisfied with the results and bought a valve cover gasket as it leaks. But then a friend of mine said its not worth it..I will get...

    Hey folks. First, could I ask that a mod change my username to "24seven" please? It's what I use on all other forums I'm on, and for some reason this one decided to link to my facebook and use my real name. Not that I mind that, it's just a bit cumbersome on a forum. Second, I'm planning to...

    I have had a good old rummage about with the search button to no avail. I know that realoem says the 523i pump and the 323i pump have different part numbers but surely they can't be completely dissimilar can they? Mine is about to fail hard. Now sounds like someone throwing rocks into a...

    Hi all, first real post here and i'm hoping its really simple, i have a '98 323i, will an M52B28 plug straight in in-place of my dying B25? The B28 is coming out of a '96 328. Are the DME and EWS the same? Will my ews, dme and key be fine to use? Anything else i haven't thought about? (the '28...
