OBDII to OBDI for an s50 b32
Hey Guys,
i'm planning on buying a 92 or 93 3 series bmw and swapping in the s50 b32 engine (euro spec m3 engine) problem is that engine although extremely powerfull at 321 horses and with the larger disp., (compared to the earlier m3 engine s50 b30) , is OBDII and doesn't respond to modifiactions as well cause of the finicky nature of its OBDII brain. Now i've heard switching an engine that is OBDII to OBDI is a federal offense and honestly i could care less seeing as how the average cop would rather pull me over for a loud stereo or exhaust. I'm wondering if this is possible i know its time consuming and blah blah but is it doable? has anyone done it? or would it be more worthwhile to up the disp on the s50 b30 that is allready OBDI.? another factor is cost and seeing as how expensive the project is in the first place I'm thinking it'd be cheaper to swap the OBDII to OBDI rather than buying larger pistons and boring out the smaller engine. Any help would be awsome guys. Thanks.
