This is not true, turbos can be brutal on engine parts, due to heat and detonation.

Detonation WILL happen. It's just a matter of when and how much.
Look, the compression on my 4.6L is 9:1. I imagine the 5 liter is similar or even less. If it's that or lower, you can probably run 5-7psi safely on it, provided you add enough fuel and INTERCOOL IT. I know Bill thinks an intercooler is unnecessary, but with 10 years of turbocharging under my belt, I know how important intercooling is to a turbo engine. I don't even like these centrifugal supercharged setups when they have no IC. Compressed air makes ALOT of heat. Heat makes the air/fuel mixture more prone to detonation. Compressed air also makes it more prone to detonation due to air friction. So the cooler you can get it, the better.
WHen you add more fuel to compressed air, it's not just to take advantage of the larger air mass in the combustion chamber, it's because fuel spray also cools down the air temp charge. Cooling the air temp charge is VITAL to avoiding catastrophic detonation.
Like I said, with the right fuel amount and the right intercooler, you might be able to safely get away with 5-7psi stock. On a turbo with an internal wastegate, they usually come with external arms and vacuum canisters, sprung to a minimum of 7psi. SO you will have to lengthen the arm or something to reduce the tension on it to bring it down to a safer 5 psi.
Look, no offense, but if you aren't willing to do any work yourself, you really have no business with a turbo setup in the first place. Turbocharging requires alot of knowledge. If you aren't up to par to installing it, chances are you don't know enough about it either. Just take your time, learn some more about tuning, and then if you want to still, do it. I am myself thinking about it, but even I will seek outside assistance, and will make damn sure I have another running car in case I go BOOM.
In either case good luck.
