In a boosted enviroment CP have gained the reputation as being one of the best in the world as piston manufacturers, a large % of australian sport compact and turbo vehicles use them, JE would be my second choice.
As for wiseco, You may have better service and support over there but here in Aus, the service is s hithouse, they know little about the product they are selling, and it is from personal experience, I had them in my last engine, rang them for specific piston to bore and ring specs, they guy told me to do exactly as was on the paper in the box, so I did. Pistons were too tight, scuffed the bores, rings butted, smashed ring lands on 5 pistons and destroyed the bore. Its great when you can give a company every piece of information about what your doing with one of their off the shelf products and they can't give you a correct answer.
