ok, ive tryed searching...and even just looking for the answer but just keep getting confused...
so my question is...
what parts can i use from other cars can i use to set up a turbo? what is a safe PSI to run on stock internals.

the 80's mazda 323s that came with the B6T engines. safe boost level??? all depends on tuning.

ya....I ran 11 psi last year with a lil oil leak...after 3k miles...hello new motor. Just make sure you are careful and do everything right..not 1/2 a--. I ran on 7 psi like a champ though

yea a have a shop doing 90% of the install....

so what are the weak parts of the motor...ive heard of everyone changing cams from the miati (sp) anything else that are common to blow when running too much psi?

Most turbo applications break their rods and cranks from over boosting with out proper timing. A few people on here say their running 13psi on the stock internals. With the oil cooled pistons in the B6 motors, they're built for boosting, but I wouldn't go to far with out a build up on the internals, especially if you have high mileage on your motor as is.

how could i get the timming right? just get it cheaked at a dealer or would a turbo time do that?

Not trying to be rude, but it seems like you have a lot to learn about cars before you tackle making a N/A motor in to a turbocharged monster.

When we say tuning, we are talking the whole shebang: a minimum of a piggy back fuel system or preferably a standalone unit. This will control your fuel maps and timing curves and allow you to safely run a large amount of boost (when properly tuned by a professional.)

I think what you are refering to in your last post is a Turbo Timer. All this really does is keep your motor running for a short period of time after you turn it off. This lets you walk away while the motor runs to cool down the turbo before shutting off the motor.

Your best bet would probably do some of the regular motor mods: cams, cam gears, probably a head rebuild, header etc... By doing these mods first and learining to do them yourself, you will become an expert on this motor, and someday build a turbocharged monster.
