to run 10Lbs of boost into your engines what has to be done, did you have to change the internals, ie pistons, rings, cam, rockers and that kinda stuff or will stock 5.2L internals be able to handle the boost?

I wouldn't run more than 6 lbs without a intercooler! Stock 5.2L have 9:1 CR which is high for any force induction engine. 8:5 CR is normal.
Running 10 lbs will blow head gaskets, cause pinging and damage. I would guess you could run 4 lbs without any modifications to the CR ratio, Air & Fuel Mixture, ECU/PCM changes.

Anthony gave some sound advice!while alot of people get away with 8psi of bost totaly stock; It is always a good idea to have an intercooler. It is also a good idea to switch to a copper head gasket. Your internal will hold up just fine assumeing they are in good shape. Do not waste your money forceing air into a tired motor. The thing that must be remembered is timming. If I have enough control over timming(retard)I would not be worried about 9:1 static compression and up to 10 psi of boost with premium gas and a moderate climate. If you go adding things like limited retard, high ambient air temps, lots of high load low speed situations then everthing changes. If you like things simple and relatively pain free get a SC Kit if you have the time and money to play around then have at it designing your own setup just make sure you get some good books. Most of the kits that I am familar with for domestic trucks come with 6-8 psi setup and come with all of the hardware you need. Includeing aux. fuel pumps, regulators, injectors(if required,)brackets, pulleys, belts, oversived fuel lines or fuel rail if required. Cooler plugs with less gap and a cooler thermostat are also a good investment. I would have thought that the Dodge would be ok with the factory PCM but I have not done a Dodge yet. For some good books on the subject check out WWW.BentleyPublishers.com.

Been running 10# for several months without any problems. I am, however, using the Superchips ICON for the custom tailored timing curve....and 92 octance fuel with some "NitroPower" from ProBlend. ;)
First and foremost, a boost bypass valve IS required for that type of boost (anything about 6# really should have one as well). Second, there isn't a whole lot of room for an intercooler but Climax Racing has a nice Liquid-Air Aftercooler which i'm looking into...pricing is rather high though.
Roller Rockers, Headers, A Good Intake System, and regular maintenance are also required. Head studs and/or O-rings are also required for anything above 10# as well as dished/forged pistons...8.5:1 is just about perfect (totally correct there Anthony).

Thanks for the insight guys I appreciate it. if I do plan on putting forced induction onto my dak which has the 5.2 with approx 75,000 k on it, very rarely gets any kind of load in the box. As for the timeing retard I wasfigureing on the MSD with retard control via a dash mounted dial. Also planned would be an intercooler.
