hey im helping my friend swap a d16 into his civic dx and i was wondering what will have to be changed it is mpfi on both cars and all but im not sure if we will need to swap a d16 ecu and stuff into it? i dont think you have to since it is only .1 ltr more but not totaly sure, also the mounts look the same so i dont think we gotta change any of that?

thanks for your help

What engine is currently in the vehicle? What ecu? someone already did a mpfi swap on the vehicle? need more info...

If someone already did the mpfi swap and is using a pm6(si) ecu, then all you would have to do is install the new engine and plug in all the connectors.

If you have an si trans I would highly recommend putting that in the car as well. The final drive makes a huge difference.

 

make sure your friend get d16z6 with si tranny or ex and si ecu or ex too

 

no he didnt i think he is an idiot but he bought the motor and trans few turbos and a racing seat for 1200
it is a mpfi on the car but im pretty sure he dosent know what ecu he has but ill check.
also it has a greddy emange if we take it off will it still be in the ecu? will we have to swap it, he has another ecu for the 1.6 anyways

 

sounds good to me

 

i take it the harness would be the same also? or do we need an adapter?

 

the d16y8 is a obd2 engine so the engine harness is not compatible with the harness in you car.
Back in the day I installed a d16y7 in my 4dr dx. I used the D15b7's engine harness. You will have to modify the harness if you plan on using the odb2 intake and injectors.
Simple wire spilce and resolder.
Sounds like you got the obd2 ecu with the engine.
I would sell it and buy a p28. That will plug right in to your existing harness.
Then just run the extra v-tec wires.

 

non vtec d16
and a non vtec d15
so it should plug right in, or should we keep the d15 intake manifold on

 

just plug right in

 

okay haha got scared there for a moment
