I've thought about plucking a B230FT and AW71 from a late model 940 turbo/SE and swapping into my '82 242 (B21F, M46). The body is great, has new floor pans and such, but the old B21F just turned 300K and she is smoking (blue) on cold starts. Engine has never been opened and I'd rather just replace than do a rebuild. Plus it's a convenient excuse to "grab" another 70 horsepower or so. :-)

The swap looks pretty straight forward. My only concern is the California smog inspection. My guess is that the emissions of a '93-'95 B230FT are probably lower, or at least the same, as the old K-jet B21. But what if not, and will it fail the visual inspection? Certainly if they are paying attention they will note that the car has a turbocharger and electronic injection, which are not stock for an '82 DL.

Any hints on passing this by the smog sniffers?
