In a 6.5L chevy diesel the forged steel connecting rods will bend before the pistons cause any problem.
Most turbo diesels use cast hypereutectic alloy, some of the newest ones might be using forged since the new pickup truck diesels make 600 to 800 horses under 40 pounds of boost.
For the KKK made K03 and K04 they are both waste gated to limit boost to between 6 and 8 PSI.
If you intercool the boost and limit boost to that level you should be fine.
I would put the waste gate boost line right off the turbo compressor.
