The stock sleeves aren't that bad, but they do crack from detonation.. not from high compression or turbos or anything else.. from detonation.

Having a turbo or high compression increases the risk of detonation, which is the reason people don't trust b20 sleeves.

The block itself is good, although it doesn't have as good of webbing on the outside for structural support as say a b16a. With the setup you mentioned, and perfect tuning your engine would last as long as you need it to, and the 200whp would be easily attained with the right head combination
