If the engine is a dual row bearing, around 1% or so failure rates would apply; but the problem is that many engines were single rows, where the failure rate is 8% or more (from Porsche's own data).

Physically, the 3.4 is a bolt in without any mechanical changes (assuming it comes from a similar year in terms of the fuel system). The DME is another issue entirely.
