I have to have the car CA smog legal, so I will have to run cats and the air system.
Is the pump electric? Is it controlled by the PCM I assume? Where does it get air from?

I'm not optimistic that you can get the LS1 into the RX7 and still maintain EGR and AIR.
If you are doing this swap you really need the factory service manual for the vehicle that's donating the drivetrain. With this, all you AIR questions would be answered.

You may not need AIR to pass emissions. Like they said, it only effects cold performance, so if you've been driving for a few minutes before your test, it won't show up in exhaust gas. It will throw an SES code unless you have PCM editing software to remove it, but I'm sure you'll need PCM software anyway to do this job. I don't know how california is, but many people remove AIR and still pass emissions fine.

I really don't think you will need the air system. Emissions tests are normally done with the car/cats properly heated, and proper editing will totally remove the code and still allow you to pass. Unless they pop the hood and do a visual to look for AIR/EGR (never heard of this) you won't need//want it.

Actually, as I understand CA's emissions laws making practically ANY modification will void emissions. In fact, I think doing your engine swap will void the emissions in relation to CA's laws. One thing's for sure, if you have to use non-stock manifolds and Y pipe to fit that car (almost a certainty) then you've broken emission laws because they require that the cats be in the exact same location as OEM (unless you've got an exhaust system that itself was CARB certified).
That being said, I know that CA is a hotbed of hot-rodding. How do the guys that make custom rods deal with this? There must be some sort of exemption available. Whatever that is, it should allow you to transplant your engine, customize the exhaust, and remove AIR and EGR.

sorry to butt in,
so basically my air system is good for nothing and once i get headers i cant use it anyway right? I know people have taken them off for weight reduction but i thought they did a little more than that.
