There is always going to be some engines that are better than others. This has been covered numerous times in every good automotive forum. The factory has certain tolerance levels that they have to meet. Meaning only a few cars are actually making it out of the factory that are build exactly how the specs say. However, knowing the crazy japanese tolerances... most of our cars are on a pretty even plain. So you should go race a GSR, if you still pull on them. You are either a great driver, and/or your car is truly a "freak" good one.
