MPFI and it's a drop it.

 

Are you using an SI trans with the d16a6 or the STD 4 speed?

 

Make sure you have PM6 ecu to run the engine properly. PM6 is d16a6 code. SI transmission is L3 is either stamped on front of transmission or above passengers drive axles seal.

 

put it in, bolt everything up same as before and go.
