Just remember that these engines are built to withstand a little more pressure than they are subjected to in stock form. Any type of forced induction or compression adds heat more stress to vital stress-bearing parts (connecting rods, crank, bottom end). Adding additional pressure than what was designed at the factory goes outside the box they engineered the motor within. If you are going to use nitrous heavily, you may want to consider beefing the engine internals up.
actually, the bottom end in the prelude, and for most hondas is very strong, the rods and crankshaft are forged, you would have a hard time finding something stronger, although there is room for improvement on the pistons
