If you wanted an HKS turbo kit made for the miata you would have to import it from japan, because it is not available from HKS USA, but I would agree with seldomseen on everything but the NOS, you might consider sway bars also, try the Tire Rack they seem to have alot of suspension components, if you are going to autoX you should probally do light mods first so then you can get the feeling of your car then start forced induction. GOOD LUCK
