That question can't really be answered very reliably. A peripheral port engine should last longer than say for instance, a bridge port because there is no bridge which makes a weak spot in the housings. But at the same time a P-port doesn't make power until HIGH rpm's, and chances are the p-port is meant to be driven 7k+ rpms at all times to get power out of it, so thats going to wear the engine out faster. Maybe somebody else will have a better answer for you.

I know an ITS car that got over 40K on a p-port on an aftermarket fuel computer

you should expect to get about 30-40k on it. it kinda depends one what apex seals you use. carbons ones wont last more than 40k if that

One of two things usually wear out first. Its either the oil control rings, or the length of the apex seals. Not the height. Most people usually get around 50k street miles out of a bridge/peripheral engine. This is providing you keep a clean air filter at all times.
Rob at Pineapple had a little over 50k miles on his, when he decided that the oil control rings needed to be replaced. The engine still started right up, regardless of warm or cold.
I had 20k miles on my first 12a pp, before i over heated it. I had it rebuilt, then sold it for a 13b pp. My next motor whent around 10-13k before i sucked a bolt, causing anouther rebuild. Sold my last motor to back to Rob, and now Blake on this forum is going to be using it for a 2002 car. CJ
