As you can tell by my screen name that i dont own a civic and dont really know that much about them but a friend of mine going to replace the motor in his 94 civic hatch and the motor in it now is a d15b8 and the motor he got from the junkyard is a d15b7 which is a 16 vavle and the b8 according to him is a 8 vavle i was wondering if he only needs the ECU for the b7 for everything to work properly or not any info will help

 

he will need a P06 ECU more the car to run.. the D15B7 is a non vtec motor.. everything else should work

 

he better get the tranny too, altough it's not the best, it's still shorter then the B8

 

yes this is true the DX tranny is shorter and and Ex is even better yet but if you are just trying to do a quick fix it will work fine
