sa22 Intake Question. What the ....
I have an sa22. While re-assembling the stock 12a engine I noticed that the rectangular opening in the center steel plate that I thought was intake is not covered by the intake manifold. It's open to the air. What's up? Herb

if its under the primary intake ports, you have an 81-85 center iron. it is the passage the air pump air gets to the exhaust manifold.
so if you have the full 81-85 engine, that will be an exhaust leak. if you have just the 81-85 center irons with SA rotor housings, it probably isn't |

The opening will need to be covered or fill it with JBWeld or other steal putty. I did an engine swap into a 1980 and had the same problem. I worked the JBWeld into a putty and it worked great.
Here's what that port looks like on my recent 1985 RX-7 build. http://i1133.photobucket.com/albums/...ps9c97d313.jpg |

For all you guys who are painting your irons, does it hold up well over time? Assume your using a high temp paint? KC, I hope you removed that masking tape on you rear iron before final assembly....
