I have a 91 integ with the b18a with the cable tranny and would like to swap in the b18b because i can't seem to find too many performance parts for the b18a. what is the difference between the 18a and the 18b. If i put a 18b head and intake on my 18a would that work?? will it bolt up and would i need the ecu? I know the b has an obd1 but are the plugs the same for the obd0? If this combo wont work can i bolt up the whole B18b engine to the b18a tranny? any helb on this would be great.

 

does anyone know the answer to this question. Please Help..
