Which compressor wheel does each have? The 7blade 56mm compressor wheel will spool the same as the 8blade 56mm compressor wheel using the bep housing. It flows 60lb/min. If if you want more turbo later you can get the t3 bep housing or use a used 12cm^2 hx35 turbine housing (t3 bolt pattern) and have enough turbo to make 570ish whp. And with either turbine housing spool will be between 3900 and 4100rpms.

EDIT: To add, if you stick with bolton . . . In the meantime, you will have a turbo that will spool as fast as an evo3 16g/td05h 18g/tdo5h 20g, but flow as much as a td06 20g or t31 50-trim.
