If its a complete motor then the easiest way to tell is to check for spark plug wires. If its got wires running to coil packs that are mounted on the front of the engine then its an NPI. If its got 8 individual coils above each spark plug then its a PI motor...

The PI motor has a better flowing intake manifold and heads, and the cam profile is different. It also has 8 coils instead of 2 coil packs and plug wires. The PI version is worth about 50hp over the NPI motor...
