i need help
If your engine runs good then just do simple stuff. Get yourself a miata torsen lsd (99' I think) and put that in, stiff'n up your chassis and suspension as you already know. Get some exhaust, cone intake <-- need to make an airbox to go with it or it doesn't really help, 6port electronic actuator conversion (because you wouldn't have the backpressure to open them if you had aft. exhaust). Get some pineapple 6port sleeve inserts, and an safc too. You can do some ignition upgrades but the stock FC spark is good to go for applications like what I've stated. That would break it loose all day long and it would feel great with that torsen over that worn clutch type lsd.
