the 3.1 is an L28 block bored over .120 (yes the decimal is in the right place datsun made a strong block) using the 3mm longer LD28 crank (from the diesel maxima), with L24 rods and either machined KA24 pistons or custom forged pistons, the N/A's tend to be in the 250 whp range, and some poeple keep the compression low and turbo them for 450-500 whp
Nissan Motorsport used to offer a kit from the factory for this
