*The paragraph specifically:
RN Series Inline 5-Cylinder 2002-2003
The later RN block from 2002 and later received a longer rod that was also stronger. From 139.5mm in early block, to the 147mm rod in later blocks. This design change not only strengthened the rods by virtue of design improvement but also by the nature of the rod duration. Longer rods stay at TDC for longer periods which extracts more power from a given air/fuel charge. This added benefit, along with the lighter valve train and better flowing heads, allowed these engines to safely make upwards of 340bhp reliably.
