So, I have what one may call a high-mileage NSX. It has over 330K on the clock on the original motor. The motor still hums along fine, and even has that throaty roar at times.
I am planning for the inevitable...the day I need to drop my motor and swap in another. That thought process leads me to wonder where I am going to source a long block and what that will look like in terms of whether it is rebuilt or just a low-mileage core.
For those of you that did replace your motor, did you rebuild or buy a built motor? Did you elect to stay completely stock? If you bought a built motor, are there vendors that are more known for this work? I don't know the C30A's tendency on wear. Do you find that the heads, rings and bearings are the only thing (typically) needing replacement or is there cylinder wall machining that needs to be done?
