I have just purchased a 2000Civic Si. The engine has 1 race on the rebuild. I am trying yo plan my racing/testing for next year with an eye towards sneaking my way into the runoffs (while spending as little money as possible).

My question is two fold.

1) How many events can this engine be expected to do before it starts to suffer significant performance losses? At that point, what is required? Fresh head? Total rebuild?

2) Do street miles (the car is SSC and street legal) place any significant wear on the engine? In other words, is driving the car to events going to cause a quicker loss of performance?

Thanks for your help
