Anybody got shots of a high-mileage teardown of an engine w/ forged pistons?
I think a lot of the issue is purely academic. Yes, forged pistons require looser tolerances and will cause more wear. How much more wear is the sticking point. Does it mean forged gets "only" 100k miles between rebuilds, or does it mean the block is good for 150k when stock pistons wouldn't wear that much until 300k?
I'm happy with the tradeoff. It'll take me another decade to reach 100k miles and being able to do so reliably is worth the rebuild cost sometime in the year 2018-2020.
