The mixings between exotic fermions in E6 27-plets (a Q=-(1/3) isosinglet quark h and charged and neutral leptons E and E) and their familiar counterparts d, e, and e are discussed and constraints from electroweak neutral-current data on such mixings are examined. We find off-diagonal couplings dhZ0, eZ0, and EZ0 and propose new methods for single production of such new fermions in e+e- collisions and Z decay. Such couplings also lead (in general) to flavor-changing neutral currents and we examine constraints on the masses and mixings of the h quarks which can be derived from the K0-K0 system and KL-.
