Jtran Sudios right? I remember that build, it worked out great with some solid fabrication to back it up. What were the specs on the back side of that turbo?
With that setup, the runner length is different feeding the turbo. I am really trying hard to keep it all equal length, so that "should" help a bit. I think the rear transmission support had to be taken off for the crossover pipe to slide over. A bit more of an involved install, but same idea.
From reading many back to back comparisons the PTE6766 should outperform the 4088 all day long, so untill somebody builds the block we won't really know how far this will go. I think deep 700's are a reasonable guess, with proper supporting mods of course.
EDIT:
I should mention that the main reason for going with the twin scroll is that it offers much larger turbine housing options...all the way up to a 1.32 a/r. The open T4 only goes up to a .96 a/r, although I think that is a "big enough" turbine to support a decent amount of power.
