for the power it made i think its pretty on par, given the t2 housing,log manifold combo...numbers seem pretty typical for the gt2871r for a turbo that spools low in the rpm range it still wasnt really dropping off in the upper rpm's like you would think.
there are things to work on, im not so sure yet.
The T2 housing isn't really as much of a restriction as you think. People make 400whp all day on sr20's with that turbo at 20 psi. Even my t2 did 350whp on an avenir manifold with external gate. When you get a chance swap the manifold out and you most likely make even more power
Depends on if that's a 56 trim 2871r and which cams.
