I've just dropped a B20 (8.8 compression) engine in my integra, with a p28 ecu, with turbo; and while driving the car spits and sputters while driving. What could be the major issue?

 

it can be many things, did you use the right ECU for the engine? and when you were installing the motor did you check the spark plugs and wires? and if you did did you put the spark plug wires in the right order so it doesnt backfire and sputter?

 

Yes, the tune up setup is all new. And yes u can use a p28 ecu with a B20 swap.
