SR20 turbo question

[1992s13_drift]

Ok, i want to boost my sr20 but i dont know a thing about turbos. I will probably end up getting the stock t25 just to make things easier but i would like to know one thing. I found a "T3T4 AR50" turbo for a good deal. here are the specs-

t3t4 hybrid turbo. ar50. 57 trim3" INLET DIAMETER2"OUTLETWET FLOAT BEARING1/8 NPT OIL INLET.50 A/R COMPRESSOR.63 A/R TURBINE.57 TRIM ( OIL COOLED TURBO)

Is that any good???
