I am going to convert my 91 to MPFI. Currently has d15 dpi. I found a completed intake manifold but i am not certain how to identify it. the guy does not know what engine or car it is off of. I need to know if it will work with my engine.

I am going to convert to MPFI and drive around a few weeks while i build my ZC motor. I want to smooth out the wiring issues before i do the motor swap. Will any intake manifold work or only the SI intake? Heres a pic if you can identify.

Thanks.

 

its an Si intake mani

 

I bought it for $20 bucks. Looks to be complete.

Another question about this swap. Do you think it would be a good time to convert OBD1 also? Where i have to rework the wires anyways. If I do this what would be a good OBD1 ECU for this?
