Usually the limiting factor IMO is the exhaust manifold flang, or stock internals.

Do you mind telling me more about the unreliable units you are familiar with?
My bad on the k03/k04 hybrids, I think most people went with them since you could get them for about the same price as K03s and people thought, "well they are part k04 they must be better" There are also some hybrids with porsche turbines.
