what it do? ive got an idea and im pretty sure it will work, but just checking. i have a 91 w/ d15. can i use the stock throttle body off an EG mpfi d15? if so, my plans would then be to change the dpfi in my car to mpfi. Wouldn't my car be running fine if i used a civic si ecu w/ some modifications to the wiring harness? any help would be appreciated.

 

Do you mean throttle body, or intake manifold? You can't just use the EG throttle body on your DX. If you want to do a DPFI to MPFI conversion, then yes you will need an 88-91 Civic/CRX Si/EX ecu and do some wiring additions.

 

then would an intake manifold off of a dohc zc motor bolt on?

 

I'm pretty sure it won't.
