Nothing. Just have $7-$10k cash at call when you need to build the engine. There is no guaranteed way to do it safely. You might be OK for a while, maybe not.
You could just pop some forged rods as they are absolutely the weak link. But once the engine is open the slippery slope starts. Just need to deck it to get a good surface for the seal. Hone the bores and now you need +0.1mm pistons. Those valves are very slightly bent.... You get the picture.
My advice is don't do anything and run the gauntlet. Just be ready to reach for the cheque book one day. If that will break you, then don't put the turbo on in the first place.
