I wonder if a EE9 civic that has b16a engine if it is possible to swap a B16B into it. Or is it easier to change the cam and camgears from the b16a to gain same power as b16b.. because i live in the netherlands and most civic DOHC vtec has high mileage.. and im planning to buy a EF9 that has a good chassis and swap/replace the engine with b16a or b16b.. any advice?
