I'm putting together the various pieces I need to legally swap a 1985 M106 motor into my 1983 323i. Both cars were imported into CA as grey-market vehicles. The e30 has a BAR sticker for a 3.2L motor, which leads me to believe I can pretty much stick any M30 variant in there and not worry too much. (alternatively, S52? there is no engine code specified on the BAR sticker..)
Several questions about this:
How do I find out the legal restrictions around what I'm allowed to modify on the motor going in? I am planning to install a MAF, bigger injectors, and completely bypassing the OE management. Am I good to go as long as I keep the evap stuff in place?
If it's BAR'd for a 3.2, is that the same as being BAR'd for a 3.2 turbo (M102)? Will I need to be using something that looks like the M102 ECU (a weird L-Jet one-off), since smog techs probably won't be able to tell the difference between a 3.2 and a 3.5 by any other means?
To what smog standards will it be held? The chassis standards? The motor standards? Any idea if the 745i CA smog restrictions are fairly loose?
To what visual standards will it be held? Do I need CARB stickers for stuff, or is that only for post-OBDI stuff?
cheers
