I have a B18b1 in a 93 civic and im just wondering how much of a difference will it make putting a vtec head on this motor and also is it just a bolt-on procedure, do i have to do anything to the ecu or what .any help will me greatly appreciated. Oh and by the way its a stock motor, no header yet or intake. just bought the car.

search.

nope wont fit, give the head to me

search LS/VTEC....its not an easy bolt on procedure...

do it, its well worth the work
