I went B series I put a b20b in my hatch and I put a ECU for an LS and the other thing I did I put OBD1 injectors from a single cam and my car is acting funny when you look at the motor is shaped weird is it the injectors or what can it be

 

Did you change the size of the injectors or did you stay the same size as before? Also, you can argue that the LS ECU will work for the 2.0L engine, but I wouldn't trust it. If I were you, I'd get an aftermarket ECU and tune the car correctly, that way you don't run into premature failure. Either that or you find the ECU for the B20 and you make sure that the sensors are read by the ECU correctly.
