does neone know how to switch a dpfi engine to mpfi cause the car is wired for mpfi but the motor is dpfi...help would b greatly appreciated...

 

If the car is already wired for mpfi and the engine you have is dpfi you will need:

MPFI manifold
Si distributor
pm6, pm7, pg7, or pr4 ecu

This is assuming you are staying OBD0.

 

You should already have the ECU if the car was mpfi, you should only need MPFI intake manifold (w/ tb, injectors and fuel rail) and the Si dizzy. All the wiring should just clip right up.

 

If your car was wired for mpfi and had a dpfi engine in it, it wouldn't run. OF course if it is running then you have to wire something differently.

 

if the engine is dpfi, don't you have to make a block off plate on the head?? i'm not sure, but i have to do this when i swap in my sohc zc, which should be going in next week. i could be wrong, i guess it depends on what you have

Usually no such block off plate is needed. I *think* you might referring to the part on the head where a mechanical fuel pump was connected on the zc. Some sohc ZC's originally came carb'd.

 

alot of work!!!!~
