if i wanted to swap my d16y7 intake manifold in for a y8 (ex). what else exactly would i have to change also to make this whole process work.

 

If your sticking with the y7 motor then use an Auto y8 manifold and use your throttle body so you could keep your 3P ecu.

 

so if i used a manual one i would have to change my tb and ecu?

 

No but youll have a dead IAC just chilling there. The auto one has it sealed up. Actually i think you could use complete auto intake manifold and TB and still keep your ecu because they both use the same 3P plug.

Hmm.... did i just think of something new right here

 

alright so i would be better off with an auto y8 intake mani and tb. thanks. appreciate it.
