Question about Pontaic Sunbird Turbo and Injectors
 
So I went to that Standard Auto Wreckers All-You-Can-Carry day today. I was looking for a headlight for my Contour but they didn't have them there, which is surprising because the wreckers near my house have about 75 Contours in their yard. As I was walking through the yard looking for things to pull, I came across one of those turbo Sunbirds. I popped the hood and was surprised to find everything intact... which was odd because someone had taken the time to steal the "Turbo" emblems off the side of the car, but not the actual turbo itself.

So anyways, I pulled the turbo and injectors. I think its a Garrett T25 with 0.48 A/R housings on both sides. I know the injectors are low impedence but I don't know what capacity they are.

Does anyone know what CC those injectors are and how much HP that turbo is capable of making? The injectors are black if that matters...

I know that on a sr20det (same T25) the engine has safe boost till 13-15 psi which produces 230-250 rwhp. But the one on the sr20 has 0.64 A/R turbine housing. Now im not sure wheather or not that'll be the same situation on the T25 off the sunbird you got. the specs are :

Turbo specs: Injector size: 370cc/min
Compressor: T-25, 60 trim 56mm BCI-1 compressor.
Turbine: T-25, 62 trim 53.8mm 0.64 A/R turbine housing.
Center Section: Journal bearings
