No-Gi

A friend gave me a jdm d15b with cracked pistons. I am considering boosting the little guy. I will be replacing the internals with pistons and rods. I have a Rev hard manifold but I am unsure of what turbo size to use. Maybe a sc50 or sc32. I will be piecing toghether a kit hoping to achieve ~250WHP on about 12-15 lbs of boost. What do you guys suggest as far as the turbo . I plan to Run Hondata, what size injectors will i need? This will not be a daily driver so i am not concerned about that.
