Obviously, some of the most popular choices are the B16 & B18. Actually, any motor you decide to use shouldn't give you many problems with a turbo, even the OE Civic motor (the D16 I think).
If you are really thinking of shooting some boost into the engine, lower compression pistions wouldn't be a bad idea but if you have enough fuel with a strong spark, you shouldn't have any problems.
