At what psi can I use safely with 13g turbos?
I found out 13g turbos are alot cheaper than I expected, so I will probably get some.

Re:
Pick up a propane injection kit (about 300 bucks) if you've got the spare money, and you wont have to worry about it.
But I think not positive, someone else I'm sure will fill you in that up to like 14psi is safe? Dunno, used to... but I forgot... I've only been lookin t 15g's

Re: At what psi can I use safely with 13g turbos?
Well you wont be able to touch anything liek 17 or 21 psi or even go past stock levels without larger injectors, an upgraded fuel pump, and probably an A/F controller. At 14psi on the stock turbos, the fuel injectors are already running way over thier efficiency range. You will get fuel cut...and it will be painful for you and your engine...boost safely...with the right supporting mods.

Re: At what psi can I use safely with 13g turbos?
How much boost can you push? Depends on your suporting mods.
I maxed the stock fuel system out on only 12psi of boost.

Re: At what psi can I use safely with 13g turbos?
What exactally are the limiting factors for boosting, what parts need to be upgraded and at what psi should one upgrade them? What is the staged upgrades for suporting boost?

http://www.3si.org/pages/stagedpower.html
this is a good staged mod site, although, I don't agree with upgrading the exhaust so early...just the downpipe. Specifically though, your injectors, fuel pump, and an Air/Fuel controller are needed if you plan on boosting past 14.5psi or if you plan on getting upgraded turbos. Also, if you boost past there, you will probably need an aftermarket y-pipe, as the stock plastic POS will sometimes blow off around 15psi.

How much are new injectors, pump, and A/F controller?
