Having a miata identity crisis. I love my '99. It's a solid car, no issues. Thanks to MR BRG it's making good power in N/A trim with an MS2 ECU. However, I'm getting to the point where I'm wondering if I wouldn't be better off with a pre-OBD-II NA car. The benefit of course being that I can do whatever I want with the car ECU-and-FI-wise and not have to deal with OBD-II. Curious to hear people's thoughts one way or the other. Would you sell a nice NB in favor of an NA? If I make the swap, the Xidas would either be coming with me or the buyer will have to fork over some serious $$ to keep them...
