Assuming that I have a Honda civic 98 dx and swapped for a y8 motor and tranny and an EX ECU, except for the y7 intake manifold. Can I simply just swap the entire intake manifold to a y8 without a problem? Or is there any modifications I have to do? I plan on just swapping the y8 IM with the y7 throttle body with y8 rotor. Any help appreciated.

 

Do I use the y7 Throttle body or y8 throttle body?

Answer can be found in there. Very thorough.

 

Ok. I suppose a y8 throttle body wont work? I will just change the throttle body rotor.
