But, it would first be necessary to reduce the compression to a large extent, before adding a turbocharger or a supercharger. And, the 16 year old main bearings would need to be “beefed-up” in order to withstand the rigors that this type of forced induction would subject the engine to.
When you take all of these costs into consideration, at the end of the day, it will still be a 16 year old car, and applying all of that money to the purchase of a newer/faster car would make a lot more sense… IMHO.
