I am planning on doing a mpfi conversion on my 91 crx. I'm trying to dicide if I should use an obd1 manifold or just use the crx si manifold. If I go with the obd1 manifold should I use a conversion harness or wire it myself for obd1? I might do a mini-me in the future so that is why i'm considering obd1.

 

use a obd0 manifold, why complicate things?

 

Agreed on the obd0 first. Get things running right, then convert to obd1 and sell the obd0 stuff. It may be a roundabout way of doing things, but I try to keep things simple.
