I have an M42 1995 ti wich is OBDI correct?
>That is correct; however I believe the LATE 1995 models started to switch over to OBD-II. I also don't know if these rules hold true globally- you may have had OBD-I ECUs well after the US models switched to OBD-II...
Wich 6 cylinder engines have vanos and are OBDI?
>I believe (and anyone with more solid information feel free to chime in) all the Motorsport engines (us and European) had single vanos up through 1999/2000 when the new E46 engne (333 HP in the us) was released with dual-vanos
Does the 3.0 Euro M3 engine with 286 bhp have vanos? Is it obdI?
>See above; I believe they did have single vanos (intake cam only)
PS- The swap is starting to grow on me again...
>Cool! If you can do it right, it is a very solid way to go.
