    OH YEAH! T70 isn't going to be able to keep up with a set of high ports and a bumpy cam like that. Sorry pal. But two would do pretty good with a smaller A/R on the turbine side

    I ran a MPT70 for a long while, and it finally was running out of steam. My combo is lil smaller than yours

    331
    Wedge Heads
    Systemax Int

    Went high 9's on 11-12psi all day. If I added boost no change, it was done.

    With that setup I'd definitely run an s400 if you're on a budget.

    A t4 s400 with a way bigger turbine wheel than a q-trim is only $800, hardly any more money than the q-trim.

    Master Power makes a nice GT45 with a 76mm compressor. The turbine is 88mm with a 1.05 housing?

    2010 'high performance' .pdf catalog lists all the MP45s with either a 77.5 or 78.6 turbine.
