I have a 99 gst and I just wanted to know how much hp and ft/lb I have with all these upgrades. So far i have an injen intake with a greddy metal i/c piping all the way to the throttle body, 5" intake filter, greddy type s bov, tsudo 3" cat back, denso irdium plugs tweak boost guage, stock turbo @ 11 psi, ngk wires and an oil cooler.
Also what would be some good upgrades to get next besides a bigger turbo?

You're probably not too too far away from the stock numbers, that stuff does make a differance but it's not huge stuff. I'm right there with you on mine except for the exhuast. If you want a little extra kick get a manual boost controller. You can get them for not too much money and they're more accurate and consistent then the electronic ones.

yea replace your fuel filters, make sure your injectors are clean, and put in a fuel pump. a 190 lph fuel is all you really need to max out the stock turbo. you would be fine running 16psi with that setup, even though it'l probably drop to 14psi at redline anyway. with your mods i'd say you added close to 30hp acording to sport compact car.
