Default ah ha.... I found What I was looking for!

DESCRIPTION:
Turbos are one of the easiest ways to get huge horsepower gains from your motor. Using used turbos will save you hundreds of dollars or even more.

The Garrett TBO322 turbos will work well on most 4 cylinder vehicles. These turbos come oil and water cooled. The turbo also include the internal wastegate assembly set at 7psi. We recommend using them on motors 1.5L to 2.2L in displacement, making 100hp to 200hp. All our used turbos are inspected for any defects and come with a 30 day warranty to insure that the turbo is in working condition when installed. Feel free to email us if you have any questions regarding these used turbos.

This model turbo is currently sold out. Check back with us periodically. We may have a rebuilt version availible or you can send us yours to have it rebuilt.

SPECS:
Garrett model number: TB2531 (T25 series turbo)
Compressor housing A/R: .48
Turbine housing A/R: .49
Horsepower Capabilities: ~200hp
Internal Wastegate: Yes
Water cooled: Yes
Wastegate setting: 7 psi


ah ha I was looking like crazy But I found it, Hmmmm But im pretty sure you can squeeze more than 200hp out of it, maybe 210-215 with tuning.. that has to be a baseline and not a limit? what do you guys think(again this is for my friends sentra se-r)

From what I read in the saab forums these turbos could produce up to 240hp on the factory vehicle, If they can spool that much with increased boost pressure my friend should be able to put out 215(his goal) on his sentra.

I cant find the map for it but if it is a t25 45 trim then it is about 18 lbs/hr of flow at 15 psig. if it is a 55 it is 20 lbs/hr at 9-10 psi. and if it is similiar to the t3 50 trim it is 26 lb/hr FWIW 1 lbs/hr of ambient air is about 14.6 cfm so the t-25 45 is 263 cfm, 55 is 292 cfm, t3 50 is 380 cfm, in comparison to the greddy tdo4 wich is 428 cfm.
