I am not an expert but a USA 3.2 has a 9.5/1 compression ratio. Running 6 pounds of boost is like running 11/1 CR which is about at the limit of most street gas.

If a Euro 3.2 with 10.3/1 would have to keep boost down to about 2.5 lbs to achieve a comparable CR.

Basically, it dose not make much sense to turbo a Euro 3.2 without changing out the pistons. A set of J&E turbo pistons should be about $1k. Your euro set has value for resale. With a 8/1 CR set you could run about 11 lbs of boost.
