i have a 1991 crx with the stock dpfi harness but it has a d15b7 in it out of a civic it has a obd0 ecu and dizzy what do i have to do for this to work or will it work at all and i dont wanna change it to mpfi this is gonna be my daily driver thanks

 

That is exactly what I have. Simply put the DPFI system on it. In other words, use '91 parts for everything except the engine block and head. You will need to modify the small coolant hoses slightly; there is an extra port on the D15B7 that has nothing to connect to, so block it off. Also rewire the fan thermal switch, it is on the thermostat housing now instead of the back of the block. Other than that the engine is an exact bolt in.

 

ok thanks i will let u know it i figure it out
