Question Top end rebuild?

If I do a top-end rebuild on my 3.2 Carrera, do you guys recommend replacing the 9.5:1 pistons and slipping in some JE Turbo pistons?

I want to be able to run 1.2+ bar of boost later, but don't want to go with the half finned 930 cylinders. I like the fully finned Carrera cylinders. I can't afford to bore them out, so I want to stick to 3.2L, but use proper forged turbo pistons.

Any recommendation on compression ratio? Car will be mainly street but see some track time, so it will see sustained high boost for long periods. I'm wondering if 7.0:1 would be good, especially since I intend to run around 1.2bar later on?
