Default Building CARB legal

Hi Iím planning to build LSx miata with NB, and I heard that E-rod engines will satisfy CARB requirements.
I know that I must install CARB legal exhaust manifold to pass smog check.
Q1. What else? Do I need something more?
Q2. Will I lose some power to pass smog check?

For an NB, you're out of luck. The E-Rod Executive Order only covers up through '95 model cars. With an NB, you're stuck going the donor route.
I have an E-Rod in my '95. Stock manifolds and cats are pretty good, you can get a little more power with headers but it's not a big deal.
