Yes, engine conversations of all kinds are common in the US. Most states have exemptions from emissions inspections for older cars, limited, or no requirement at all. There is no restriction on the importation of parts, other than our now higher tariffs (sigh).Is the Honda-conversion Elise available in the US? Just curious...
I have friends in my home state, which considered one of the stricter US states, and one has installed a LS V8 engine (Corvette) in a Miata, and another has put an LS V8 in a Cayman.
