    sounds like you need to do more research my friend. s52 is a 3.2 liter? s50 is 3.0? s50 is odb1? s52 is odb2

    Got dayum. I'm tired of my m10 lol. Is there any difference in the s50 from the s52

    Yeah okay thanks for the heads up! I definitely want an s50. How hard is it to source one? And how much do they usually go for?

    So I'm really considering an s59 swap! Its a greater improvement from my m10 and is cheaper than turboing an m20. So, i found this on my local Craig's.. Is it an s50 to begin with, and is it worth it?!

    In the process of buying an M50B25 from someone that does swaps in the UK, so I have to ask a lot since I'd have to sort out freight and what not. So I decided to ask the guy about the additional parts required, and listed the parts on the main post of this thread and he came bake with the following differences:

    E28 motor mounts - E24 USA Mounts
    E21 brake booster - He says he uses another but didn't specify

    The engine is being supplied with the standard 5-speed manual trans, he says E30 M20 mounts should work for that.

    Has anyone had experience with any of these with their swap? Or can shed some light? I won't doubt the guy, I'm sure he knows what he's doing but I just want to see what you guys think.

    EDIT: Now I'm seeing most of the differences are also interchangeable...

So, after reading a lil bit, The body connecter is different, (round vs square pin), than the 84. So how do I go about swapping it into my 84? I'm having a shop do this, so I'd like to make this as straight forward for him as possible. I thought I read there's pre made adapters from someone on here?
    There's a few of us who make harnesses/adapters, but if you are having a reputable shop do the work, they should not have an issue with the connector.

    Get in touch with 328i junkie on the board or go to his website at Markert Motorworks and have Dave build you a harness. It will cost a few bucks but I keep hearing about all the positives of going this route and wish I would have done the same.

    So alloy blocks, and I'm guessing on N/A cars there are a few months after the switch from M/S50's to M/S52 where they still drilled all three holes. I was preparing myself to drill/tap, delete TB heating etc and this saves me from any hack work
