I broke down and purchased a 2000 Miata, I needed AC for the hot desert drives. I have a list of things I wanted to install but I have a question here. If I upgrade the exhaust, what should I install in case I ever want to add a turbo? I am thinking about the exhaust, and suspension and or shocks this time around. I was happy with the KYBs at full stiffness on my 95.
