Is the exhaust housing divided or undivided? If it's undivided, is there a way to get a divided housing put on the turbo? (I don't know a whole bunch about them, that's why I ask)
for what its worth i have a garrett gt4082 with a 0.68 a/r turbine housing and plan to go for low-mid 500's. if i were you id get the 0.68 a/r housing. itll spool waaaaaaaaayyyyyyyyyyy faster then that huge 96 a/r.
I dont know how i keep out of fuel cut, my car is wierd. Im able to boost about 30psi with 110 octane... and its still running pretty rich at that point.

I have made another new turbo exhaust housing and it is a T4 undivided. It has an AR.81 and has a v-band with a 3" or 3 1/2" hook up for the exhaust. It is the same as the other Boss housings and is made of stainless steel and weighs only 7 lbs.
You could replace the Boss housing you have now with this new T4 and should be ready to go. This new T4 will be on the web site just as soon as Jack takes some new pictures of it.

How much is the new exhaust housing? Also how much of an increase if HP could be expected from upgrading the housing?

till you drive it... my stock turbo did 436rwhp but it peaks and then starts to drop off. The mp turbo did 420rwhp but car the car was much faster. Just hearing a number won't help you it depends on the set up and supporting mods to give you the power under the curve you need. I smoked a zo6 with this setup and was on a vpc and stock cam. Now if you still think it sounds low then you need to rev to 8k and put on a 74mm.
Bigger turbo will make more power across the entire range so "Feels" MUCH more powerful than the peak numbers show. 
i to am looking at getting a masterpower T70 .68 a/r but i also have a load more fuel than u guys so far aeromotive A1000 pump, 880cc PTE and Map ECU management and EVC for boost. i dont care about streetable, any turbo is streetable it just requires a little throttle control haha. i was shooting for a 700hp mark but at the same time get a good fast spool, i hear the .68 should due it but i dont know, i'd almost go with a little bigger one.
