Actually, the stout bottom ends and and LACK of the factory pushing the envelop on things like compression and forgiving valve train geometry make the 5.2 and 5.9's good candidates for boost..
As stated: better head studs, better gaskets, 4bar MAP, injectors, and TUNE, and you can boost relatively easily, but never cheaply..

Never said it couldn't be done.
How much time, money, parts, and effort went into what you did though?
I guarantee it wasn't a weekend project. Just trying to help the kid out.
Yes, anything can be done. But getting something done and getting it done right are two complete different things.

Okay Ive done a bunch of reading the last few days to figure out how to hook up a turbo. I understand that much of it know and I have done alot of reading to try and figure out the electrical part of it. I think Im going to go with a standalone system, 2 bar map, and the wide band O2 sensor.
You never said what year your truck is, if it's OBD2 you can run SCT and have it tuned for boost but IMO it's not ideal at all.
There's several different ways to install a MS system, I'm doing it the simplest way right now, just controlling fuel only, the wiring took about 3 hours. Any standalone computer should come with it's own MAP sensor (the default MS sensor is 2.5BAR). For timing I have a MSD BTM which retards timing under boost.
And trust me, you won't be happy with 4PSI
Or if you meant the turbo system, I worked on it for a couple weeks, the truck was only down for like 3 days for install stuff though. I've got 35k turbo miles on it now.
Sure if you just throw boost at a motor (stock or forged) and don't do anything tuning wise it's not going to last long but most people don't realize how much abuse a stock motor will take as long as the tune is good.

As Hahns told me, that guide on MegaSquirts website is your Bible for the standalone computer. Read it. Every bit. It can do so much and be so powerful, but requires alot of knowledge to successfully complete. Getting the vehicle to run is one thing. Tuning it after is when it gets fun. I think Hahns said it took him a week (?) to get his Dakota running, and a few weeks of minute detail tuning thereafter. I've got a home brew water/methanol system on my Ram and have been researching the MS standalone for quite some time, on and off. Turboing your engine isn't going to be easy or cheap by any means. There are so many variables and conditions that have to be correct to run the system properly. Hahns will be your best friend when you decide to ask a technical question. But PLENTY of research will be needed in order for you to understand. Look all over forums and books and get to know all you can. You can't get a basic knowledge of it all quickly. You need to be able to learn in your dreams before your understanding. But as I've been told, "Go for it, dude!" Good luck

My truck is a 95. Im not sure what OB2 is or what IMO so not sure. What size turbos should I look for. I have a 360 and im going with twin turbos. I dont want turbo lag. also is it possible to flip the manifolds upside down to hook the turbo to it. And if I can use the Sct will it come with the tune already on it or will i have to take it some where to get a tune. Also can I change the rev limit and shift points with the Sct like a Hypertech programmer.

I have been thinking for no more boost than Im adding I can achieve that with one tailpipe turbo. What size turbo do you think I should go with now. I also am wondering, will water hurt the turbo. I will make a skid plate to cover it but i'm wondering If I should completely surround the turbo with drain holes for the water, or will that overheat it.

Water (and snow) will not hurt the turbo. I live in the PNW, it rains a lot here. Sure, if you submerge it you're probably asking for trouble.
For a 5.9 I'd look for a something with a 67mm compressor and a P-trim turbine wheel/housing, with an A/R of .68 or .81. T4 exhaust flange for sure. Contact a dealer such as M&M turbos on TheTurboForums, I'm sure you could get one for under $600. http://www.mpturbos.com/mpturbos_009.htm Avoid China turbos, there is one good one called the GT45 but it's bigger than what you want.
You can see here a T4 undivided housing vs a T3 divided housing (what you'll find on a CTD and my truck currently).
