I have a 2000 EK sedan w/ a JDM D15b head and Y8 block. Im currently using the a ODB2b Y7 dizzy. I need to know if I need the ODB1 dizzy since the head is ODB1....also is there a difference in a vtec/non-vtec dizzy?? Obviously the ODB2 dizzy wont bolt up correctly to the head so that's a given. Just need to know which dizzy I need...are all ODB1 sohc distributors the same?
