peeps have put v8's in civics, its doable, but not without some serious fabrication. besides if your gonna put a six in there, at least make it worth it, put an nsx motor in there (yes its been done)
its possible, but i doubt its probable, for the amount of time and money youd spend you could do a b series swap and boost it, and still smoke the accord v6 for less $
not to sound like an ass but dood, if you think that the b16a2 costs too much. don't even talk about a gs-r motor. think the grs motor costs like almost around $1500 more than the b16a2 motor.
not worth it .... you want mad power go for an h22 at least there is s**t to put those into civics and it will haul just as much ass as a v6 accord will.
The C27(170HP) & the J30A(200HP), can not be fitted in any Civic/Integra, It is far from plug & play. Anythings possible but for the money to do that you could probably build yourself an allmotor high to mid 12 sec. car. I'm sure many people has asked themselves the same question before, so don't feel that it was a dumb question.
