ok i know i asked a simaler question before but now i want to narrow down the question if i run 15 psi on stock everything exept my bottom end and exhaust would i be ok? or am i gonna need a fpr fuel pump and 550cc injectors first? thanks.

Wait so your bottom end ISNT stock? 3 inch exhaust?
Jsut keep the boost down untill yo uget some money to build/
15psi on stock fuel is risky...Any number of things (all completely out of your control) could cause you to run lean long enough on stock fuel. Think about it:
You have a 13+ year old fuel pump, fuel injectors, and possibly fuel filter as well. Any one of these components has a bad day, and boom...there goes the $1200 you spent on your bottom end, melted piston pieces eff up your head and turbo, plus then you'll need a hg and whatever else gets effed.
Can you do it? Sure, it's been done. The thing is, even if you have documentation of every mile and every service report, you can't be sure if stock fuel will hold up at its upper limit.
^^^ I know this has been said before, and it's just a repeat...but there's no way to know if it'll hold until you try it.
If you really want to see if it can do it reliably under controlled conditions, go have it dyno tuned with a wideband, turning up the boost slowly. Pay special attention to the A/F as you go. Watch for boost spikes and matching fluctuations in your air/fuel ratio. Of course, you're looking at possibly $100-200 right there just to dyno test, unless you've got an in at the local dyno shop. That's money you could spend on a fuel pump, new fuel filter and maybe 1/6 of the way to a new set of injectors or a nice FPR

and mods are full bottom end, stopper mhg, and 3in maybe 4in exhaust i havent desided yet the car isnt running just wondering for when it is. also i was gonna do the maf srew trick to raise fuel cut
