    Hello, I have an e36 1995r with m52b25. I decided to change my selector to a short shifter, and there has been a problem since then. When changing, I heard a knock in the box, but I thought that something fell to me. However, once everything is installed, the gears are very hard, you have to use...

    After exploring what features can I test and change on NCSExpert + Dummy with K+DCAN cable, I saw this Immobilizer was inactive. So I set it active then write the code. Then,I tried to start the car. It cranks, but engine won't starts. I've researched on forums and youtube all leads to sync...

    Right this will be long. Last year my E36 328i from 95 started to develop an engine issue that I couldn't fix yet, today I ran out of ideas. It all started with stalling when it was idling, then it turned into a permanent misfire. At first, I plugged it on inpa, I had the following error...

    Hi! I'm looking into buying an e34. I would really like to turbo it aswell. Since the 518, 520, 525 are cheaper than the higher power ones I'm thinking of eventually doing a complete engineswap for a later gen engine. At the moment I have my sights set on a m52b28. Not sure if it is good for...

    So my car has a knocking sound, it started maybe month or two ago, took it to the mechanic and he said that it's normal for these engines, however, it became louder overtime, and more agressive, at first it was like tapping rather than knocking, i think it is coming from the top-back of the...

    Hey guys, so my E39 has started using so much fuel, it doesnt say it on the board comp. but i see the needle drop very fast, faster than usual, and also on cold starts it has a very bad idle, shakes, missfires, rpms jumping, as soon as i touch the throttle it forgets it has to idle and shuts...

    Hello guys I am looking into upgrading my intake manifold (m52b25) and i want to ask which manifolds would you recommend m50 m54b30 or m52b28 and what does each of them need to be fitted anf what the gains and losses would be from each one ? Thank you in advance.
  11. E39 (1997 - 2003)
    Hello all, I'm here to ask for a little bit of help. For future reference, I've got an m54b30 engine in my e39 which came with the m52b28tu, so I have the Intake manifold from the 2.8 on the 3.0, but that's the only big difference from the m54 that's in the e46 and my e39. I'm running into an...

    Hey guys, another problem again... so my e39 has got around 110k original miles on it, which is not a really lot, however, recently it started burning oil from time to time(it didnt use oil at all until recently now it's using a fine bit of it about a liter per 2000km) , and occasional smoke...
  13. E39 (1997 - 2003)
    so i had an intake leak, my rubber air hose had a crack in it and i had to drive it 2 days like that until i found a new one, on idle it was smoking like crazy, assuming it was running very rich, very low rpm, like 400-500, shaking etc, sometimes it would turn off, had to drive it until i found...

    Hi everyone. Recently, I purchased a 1997 BMW 528i with 79k miles on it. I’m currently doing some research and just trying to understand the limits and how to do stuff with this engine. Not much Has been done so far, a muffler delete, I’ve got a m50 intake mani coming, did usual maintenance and...

    hi, Im in a bit of a pickle, while I was “rebuilding” my vanos I stripped both the torx screw that is reverse thread connecting from the spline shaft hub and cam gear piston. I should of replaced them the first time I redid the vanos (stupid of me not to) I managed to get the bolt on the intake...

    I have a 98 323is and I know they exist or exited but I’m looking for a tuner chip for my e36 that deletes the secondary air pump and tunes for no cats. Sadly with all this epa stuff I can’t find them for sale anymore wondering if anyone has one they would be willing to let go or knows where I...

    Hey guys, i have a ‘97 523i M52B25, single vanos, basically the same engine as in 528i just a smaller displacement, so the problem is whenever i start the car and it’s cold outside i get this awful rattle for like 2-3 seconds, the colder it is the longer it rattles, but it’s like for a few...

    My alternator started screeching badly over a period of 3 weeks. The vehicle would not start a few days ago (potentially parasitic drain from the rectifier). I was mindless enough to initially partially detach the positive on the alternator while the battery was still attached (3am in the...
