how much boost?
is the motor stock?
what size injectors?
tubular or log style manifold?
Average temp around your area?
what compression you look at running?
what Octane you going to run?
whats your altitude?
at around 5 PSI with a 50 ar I would say maybe around 240-260whp? depending how aggressively tuned the car is might want to look into the .63 ar for the B20 though

To answer the question,
T3/T04E turbos usually don’t have a .50 A/R ratio but there is a common turbo called a 50 trim which is the diameter of the wheel in the compressor(cold side) housing. The exhaust side is typically .48 A/R ratio or .63 A/R ratio. With the smaller A/R ratio you’ll get a quicker spool but worse top end and total power, with the larger A/R ratio you’ll get slower spool time and a bigger total power output.
I’d say with a 50 trim you’ll be lucky to get 450 flywheel horsepower total, probably not 450 wheel horsepower. And that’s a total, not on top of your stock horsepower rating, because all of the air flowing into your engine has to go through the compressor side of the turbo, so it becomes limited with the 50mm sized wheel. You could try a 57 or a 60 trim for a tad more power.
