Long story short
I have purchased a log kit from real quick like 2-3 yrs ago one of his 1st. This one came off of 1982z28with18s car.... Anyways lost interest in this for a good while, the other day I was figuring how much $$$ i have in this pit, which made me decided to go ahead and get the thing going.

To the point:

Which exhaust housing would be better for this kit, the .96 or the 1.15 twin scroll. I am thinking the 1.15 as it will flow more up top and spool almost identical to the .96 housing. Any insight on this would be appreciated...

 

Why do you say spool will be almost identical?
What is your boost pressure and actual flywheel power?
P-trim exhaust wheel? S-trim? 76mm compressor?
If the car is your daily driver the .96 might be a smarter choice since it will shift the powerband a bit lower than the 1.15. If you're just trying to impress with numbers or running at the track I'd try the 1.15 and go from there.

 

TC76 F-1 GTK Turbine wheel. Hoping to run it at 14/15 lbs no low/high boost setting. I want it to run top notch all the time no excuses. Lot of h/c/n20 ls1's around here. this car will be more of a weekend cruzer
