I have a 89 probe GT with 98.5K miles, 122cc turbocharged engine (actually its a Mazda engine).
I want to upgrade the stock coil and distributor with perhaps products by MSD. There's nothing wrong with the stock ones, except that they have nearly 100,000 miles on them. What about the spark plug wires, they are the original also.
Is there any problem with this? Could I expect to notice any performance increases.
