      Just as a data point, I just got my S54 swap into a 95 obd1 M3 through BAR, and I think most of what I did can be duplicated on an e30. I'll be writing the swap up this coming week, but its doable.

        So, after 10 months of trying (5 Ref apts), I finally passed this week! Completely Legit M52 OBD2 swap. Here's what I did to pass:

        All OBD2 smog items needed:
        -Fuel Pressure Sensor (off evap gas tank)
        -Evap Charcoal Canister (in trunk)
        -16pin OBD2 diagnostic plug under dash
        -Markert Motor Works added plugs for the above (from 328i body harness) to the M52 engine harness with extra long wire so they could extend to trunk, dash, and gas tank area. Also did my tune remotely via my laptop. Very very cool and helpful!
        -stock air box would not fit so I got a Rogue Eng Air intake
        -completely stock exhaust except bent to clear subframe is ok. After post cat O2 sensors you can use your e30 stock catback. That's what I did. Here's what it looked like before I had to change out the bad stock cats with the Magnaflow universal cats:



        The used e36 cats I purchased went bad so I had to get CARB approved Universal Magnaflow cats (2ea) welded in. The weird part was that I had to have the exhaust hang down a bit lower to make sure the post Cat O2s clear the underbody. The ref failed me once because I had my O2s enter post cat from a horizontal position. Apparently CA wants EVERYTHING to match exactly though they were ok with bent down pipes. Once I put the post cat O2s vertical in the stock position, they were cleared. I don't think normal smog checks will be this anal.




        I highly recommend that you get a code reader and 20 pin adapter:

        I used the iPhone app OBD Fusion. Here's what my app looked like when I passed:

        No CEL:


        Monitors Ready:



        I almost gave up multiple times and I seriously could not have done this with out Dave of Markert (did a tone of work on my harness and tune and put up with all my lack of general knowledge or car common sense) or arch4ngel (walked me through the FPS and charcoal canister which were crucial to CA Smog).

        So excited to be done!

                Just picked up an e30 and I am interested in s52 to OBD1 swap to get it BAR'd as a 1995 S50 M3. I've been following up on other BAR'd "1995 S52" swaps and the OPs never mention what they told the REF when asked or to produce paper work what donor car the motor came from. I know they wont be able to see that it's an s52 block with all the other components in the way but what advice or what should I tell them when I buy an s52 from ebay/shop/junkyard but want to tell them it's a '95 s50 (has the s50 intake manifold and valve cover, etc).

                  I think the 1995 S50 uses a DME specific to that year. so vin # on DME label would need to be for a '95 S50.
                  not the more available 'red label 413' ??

                      LOL I spent hours last night looking for a 506 ECU. Seems to be the hardest part is finding the ECU for an OBD2 to OBD1 conversion.

                      This guy used a TRM ECU though but his Ref didn't check the ECU.

                      Based on past OBD1 vehicles I've owned and from research. it seems to be that OBD1 is easier to ref (kind of) and pass smog once BAR'd. Easier to run after market parts or mods without throwing a code and also pass emissions with OBD1. But I could be wrong.

                        Its a smidgen easier to bar but more difficult because you have to deal with them potentially catching on its an S52 running OBD1. Wrong ECU and whatnot. OBD2 is more mod friendly and easier to tune than OBD1. Mr. Green had no problems passing once he got a good set of cats in there and im able to remotely flash his car for revisions anytime he decides to upgrade stuff once he got through BAR.

                          Now that I'm done, I'd totally recommend sticking with OBD2. If it throws a code, it's so much easier to locate and fix. Much better tuning options too.

                          My biggest stressor doing this was sap, the cc, and fps. I was worried that these would throw codes very easily. Not the case for me. Also, at the time I was trying to do it, there really wasn't any DIY on CA legal OBD2 swaps.

                            That's awesome! Good to know and thank you!

                              This seems like the dream swap. Other than the E36 interior's notorious quality, I'd love to have an S54 E36 sedan. I read that the S54 is much more difficult, due to the evap tank, the OBDII, and the numerous other computer systems in it?

                                Did you weld up the exhaust, and then paint it, so it looked stock? Surely they knew it was freshly painted?
