    Drivetrain is out of the E30. I'm moving into parts accumulation phase. What CARB legal intakes are out there?

    Ok, so here we go! I have a 99 M3 donor car being delivered sometime within the next week or so. I'm going to keep everything stock and basically just move everything over. Just a couple questions so far:

    * Who have you guys used for any engine harness mods and DME flashing? Anyone do that here in Nor Cal?

    * I take that adapting the harness allows the existing check engine light to be utilized?

    * Does the OBD 2 port have to be mounted at the driver's kick panel, or just anywhere accessable?

    I just want the BAR experience to be as painless as possible. I'll be going to Las Positas here in Livermore which I have heard is not too bad, but I don't want to give them any reason not to pass me.

    Thanks,
    Sean

    I'd do it if you're seriously considering it. With enough research, it shouldn't be too hard if you have the donor car. Resale on the swapped car bumps way up if its been BARed too.

    Ah yes, the OBD I vs II, I forgot about that, but still, with an entire car, it shouldn't be that difficult (famous last words!)

    Should probably just forget about it and register the car in another state

    the difference between 95 and 96-99 M3s is OBD1 vs OBD2, which have vastly different capabilities and are subject to different evaluation processes at the ref.

    it's doable OBD2, as documented in this thread and numerous build threads, but it is less easy than OBD1.

    So, collectively, do those of you who have done this swap and kept it CA legal think it is doable with the 97, or would I be better off to keep looking for a 95?

    That's what I thought, but is that just due to the air pump set up? I'm thinking I could relocate the battery to the trunk this giving me a place to mount the pump in the engine bay. Is there anything else that would be difficult to swap over?

    Just as an "am I going in the right direction?" question; I am looking at a 97 M3 and can potentially make a deal for the entire car. Would this be a good candidate for a swap over to my 88 convertible? Would the extra smog shit (air pump, etc) make it more difficult than another model year of donor car?

    Thanks,
    Sean

    Hi Guys.

    Let me clear this up...

    I had a M52 with M50 manifold, S52 cams, 21.5# Injectors, OBD1 TRM Tune.

    I started with a stock M50 downpipe with ~150k, then to a slightly modified (just to work on OBD1) S52 downpipe then finally brand new Magnaflow CA legal cats. The tune also changed a few times....

    I blame 2 things for my car not passing:

    #1 I shouldve listened to my mechanic and bought a WAR chip so he couldve created 2 tunes for me, a SMOG tune and a performance tune. I didnt listen and bought off the shelf chips for my modified car.

    #2 The ref would let the car sit for 20-30 minutes when I would arrive, so the cats were never really warm enough, and combined with #1 this resulted in it not passing the tailpipe emissions test and No BAR sticker.


    To answer your questions, he never checked the engine. I showed him the VIN sticker on the ECU and we went based off that, but your results may vary. The closer to stock the car and motor are, the easier it should be. Mine was quite a big off of what a stock M50 was so it made my life harder.

    It all depends on what you are starting with and what resources you have to accomplish the swap. Parts car on hand is the most ideal start. I had none of that.
