From that wiki:
Honda B engine
Commonly swapped into: Honda Civic, Austin Mini (1959-2001), mid engined kit cars
Not suitable for inline RWD layouts, because engine turns counter clockwise (Chevy Corvair flat six turns the same way).
Chevrolet Corvair engine
Commonly swapped into: VW Type 1, VW Type 2, Karmann Ghia, light aircraft, dune buggies
Turn in opposite directions to most engines, bar those made by Honda.
