Rep Power: 0

Ok, so im thinking about doing a custom or a kit that comes out in the future. But thats not it. I also want to change around my bottom end of my engine. The question I have is there any way for me unless having the engine ripped down after they build up the bottom end, to tell that they did in fact put in the new parts not just say they do? I just dont want to put out like 1500-2000 for pistons, rods, etc and then get ripped off. Also, if I ask him to see the parts that are going into the engine, that might **** off the company and create more problems. So, if anyone has any ideas, I would gladly hear them.

A custom turbo I think you meant, right?

If it's a reputable company, then you can be sure that they actually replaced some stuff. You'll need to find out if they're reputable or not.

Otherwise, I guess if you run a higher boost level, and go past the level that the stock internals can handle, and nothing breaks then you're golden.
