i currently have a d16z6 vtec in my 93 del sol si and want to swap it out for possibly a b18c or a b16 have not 100% decided if i do the b16 would the tranny from my current motor fit it? should i just turbo my d16? im not new to the car world but am new to the honda scene. i plan on boosting any of these 3 motors with a custom turbo setup any suggestions are welcome. i am staying away from the h22 because it is to much of a pain for this little car.

Only another B-series transmission will work with a b-series engine, so you won't be able to use the z6 transmission. Check out the swap thread in the '92-'95 Civic forum, that might help you decide on which engine to go with.
