1) Cant help you there
2) Dont run any more than 14-15 PSI at the MAX on the stock T-25 with stock fuel.. Stock boost is about 10-12 so you wont see that much more at 15 for power

Your ratio should be around 11.5. Remember, the higher, the leaner, and the lower, the richer.
You could prolly get like 250hp out of the stock turbo. Thats about it.
As for the injectors, look on dsm tuners.com or dsmsource for used stuff. If you want brand new then go to slowboyracing.com or buschurracing.com or amsperformance.com, maybe even extremepsi.com has them (not sure)
Good luck.

I have this set up: Dave brode upper IC pipe, 2.5" magnaflow exhaust, K&N filtercharger and intake, AEM tru boost, 1g BOV, ACT2600 clutch and streetlite flywheel I run 16 to 17 PSI on the stock turbo perfectly fine anymore than that you will need upgrades.

the most youll stabilize is around 15psi... I ran somewhere up to 21 by accident just messing with my boost controller, but it would just spike and return to 13-15 (its not good for the turbo though to be higher then 15)

thats far tooo lean ... your bound to melt something and im just having a hard time seeing how you makin power
a safe range for turbo cars is between 13-11.5 if your in the low 11's you overfueling for an inneficient IC or a maxed out turbo that works past its efficiency range and instead of compressing the air also overheats it!
been down that road an it just not worth it. if its in the case of the turbo ... time to upgrade to something a bit more efficient

for 660 cc injectors should i go with a 255lph fuel pump or the 190lph one cuz they both cost the same?

The 190 is fine. The only problem with the 255 is that you need an aftermarket fuel pressure regulator. So, it does end up being a little more.
