I've had my miata a -long- time. Since 2002 I think. Funny because I remember asking on this very forum if anyone thought it was a good deal and everyone thought it was not. It was 4500 bucks with 92,000 miles or so. It's a 1992. So, here I am still with the car a decade and a half later. It's been rebodied after it got hit. I used a 1994 tub purchased from metalman here on the forum. I used the 1992 harness with the 1.6. But, eventually I swapped in a 1.8 from yet another 1994. So now it's a 1.8 powered 1.6 wired 1994. With the 4.30 rear from the 1992. It's fun to drive. Then, several years ago I score a supercharger from I think a 1999. For sure an NB. The guy was upgrading to Flyin Miata turbo. M-whatever model supercharger. Who knows. Anyway it was cheap, no intercooler but the brackets and such are all there. Lots of miles, like 100k. I dunno. I think it has a power card, but I don't know what model power card it is, and after emailing back and forth with the power card people eventually they told me "if you don't know what year this card came from we can't say for sure what model it is" or something like that. Not really sure what to do with it or if it's still around. So what should I do? What would I do for engine management? I want as simple as possible. I'm not interested in mega squirt or anything. Just simple. I don't even care about big power, just a bit more. Any suggestions? I may have even asked these same questions a million years ago.
