I have a 1989 Civic that had a D15B7 in it, and somehow the engine harness was wired for OBD1 (or at least to some extent), and I am putting my 89 DOHC ZC in. The only problem is my B7 throttle body had a MAP sensor on it, and the ZC TB doesn't. I tried to fit the B7 TB on the ZC manifold and the holes weren't the same pattern.

So I guess my question is what do I do? Do the OBD1 ZC TBs fit on the OBD0 ZCs?? Or should I just try to convert back to OBD0? I know this was confusing, but I tried to slim it down . TIA!!

 

anyone know where I can find an OBD1 ZC TB?

I just realized I use too many abv's. .

 

i know that a d16z6 tb has a map on it, but dont know if it will bolt up

 

I don't think it will because I think the Z6 and B7 are basically the same. Thanks for the input though

 

Anyone else have any ideas?

 

you could easily pick up an external map sensor and get a "T" fitting and t off the vacuum line

 

Hmmm, I've never heard that before! Could you explain more, or give me a link or something please!?!
