I have a 1991 Honda Civic std and id like to get so better performance out of it. The previous owner put installed D15B7 engine and 5spd transmission from a 5th gen DX but, didn't swap to mpfi, leaving the old std dpfi setup and its pm9 ecu.

I have reed many dpfi to mpfi swap forums but should i get the obd0 4th gen Si parts (will they even work with this engine?) or should i upgrade to obd1 and get what the D15B7 engine came with?
