im looking around to see if my old d15 will swap with a d16 zc if so can anyone tell me what i need and if the ecu ar the same for both cars. im gettin two ecu with the motor i am buying so if anyone could help me let me know. also wil the distributor of my old motor fit the new one

 

and does any one knows if the ecu will fit

 

So you have an ED with a d15b2 (I'm assuming), and you want to swap in a D16a6 (or ZC? SOHC or DOHC?)

If you search using the full engine code you might find some helpful results.

 

if you use your d15 intake manifold on the zc (assuming its the sohc zc non vtec) you will not have to change anything for it to run. and reuse the d15 distributor on the zc as well.
ecu's are different. d15 is 2 injector and zc of 4 injector...
look into dpfi tp mpfi swaps as well.
