If you build your 200 six with all of the same kinds of modifications we make with V-8s, high-revving, snappy performance is possible. Good dynamic balancing, coupled with oiling-system modifications and the right selection of components, will get you screaming, high-revving performance. Hypereutectic pistons are enough for most street applications. Use forged pistons if you're going to spin it high for extended periods or with turbocharging or supercharging. The use of nitrous takes a lot of thought and planning.
