I have a civic with a b16 block and b18 head and was wondering what i should do...keep this setup and build it or go to b18 block or b20 block?...i do plan on turbo so i think this may be the best setup but i want to hear what everyone has to say.

 

i don't too much benefit out of running GSR head on B16 block. sure the GSR cams are slightly more aggressive, but you are being limited by displacement. i am assuming this is a street car? if so, you will appriciate the extra torque of a b18 or b20, when you cruising around.
i think anyways.

come to think of it. it all depends on your goals. b16/GSR could work just fine for you. i should not have posted. i don't know much.
