Here's another example of liking the individual hardware pieces, but being repulsed by the idea of the ultimate combination. RX7s are cool. Grand Nationals are cool. But a vehicular mash-up of a 1993 RX-7 powered by a Buick GN's V6 seems a little weird. Weird to think that it even gets past regulatory agencies, as it's an older, totally alien engine in a newer car, which might make it interesting to register in a state with California emissions. The swap is well done, though, even if we'd question the handling a heavier and much more powerful engine in the snout brings with it. It's fast, but does it understeer like a pig and snap the tail out? The seller seems to have focused on posting low elapsed times in the quarter mile, so think about that when you conjure what the dynamics may be. Follow the jump for more.
