Hi Folks

I'm retrofitting a 1980 California 12A engine into an RX-2. I'm having some trouble with fuel delivery and crankcase ventilation due to parts mismatch I believe. I have a First Gen intake manifold that I think I'm going to use (currently using a 73 intake on the 80 engine) But I don't know what year it is. I need to know the year so I can get the right ACV block off plates and gasket.

The manifold has a shutte valve, and a long extension coming out towards the firewalll side with a oval shaped end where something would bolt on using 2 bolts and a football shaped gasket. Can you tell me what year manifold this is?

thanks in advance

 

if it has a shutter vavle and a rectangular air injection hole under the primary runners, its a 81-85

 

Sounds like an 81-85 manni.
