Default Another help me pick thread: GT91 vs. BWs482

So now that I've been plagued by indecision for the last few weeks, I figure its time to put this out there and get some opinions. I contacted forced inductions and they suggested the GT91 1.08A/R or the BWs482 w/race cover 96mm turbine wheel and 1.32A/R for my goals.
The motor is an lq9, stock crank, forged rods & pistons(@9.5:1),custom cam,ls6 intake, stock truck throttle body,arp studs throughout. Goal is 8-900rwhp all day and 1k+ when turned up.
The car will be 99.9% street driven. Both turbos will make the power so what im looking for is the quickest possible spool. The GT91 is an open housing but is the less expensive option. The BW is a divided housing is about $250 more but lets me use a QSV(another $400). I know $1300 vs. $2000 seems like a no brainer, just interested in what you guys think.

I think a 91 is too big for the street,
have you considered the 4788?

I hadn't considered the 4788 but from what I can see unless its used it's definitely out of the price range

How about ST80 or SX80 with no spool valve. Keeps it simple, no spool valve, but quick spool with T4 housing and 83mm or 87mm turbine. Arent people making 900whp with that? If street driven you might give up a little power to gain spool quickness, the midrange torque is where all the fun is on the street, not peak numbers. Good luck, tough decision for sure!

Its enough to drive you mad! I know what i want, just dont know what i need. Im leaning more toward the 91 for simplicity and price. I mentioned the QSV when i contacted forced inductions after reading the Zombie threads and thinking that would be awesome for the street. That may be the only reason they suggested the s482. I know it seems like ive answered my own question but i wanna do this right the first time. Thats why i really need to know what you guys think.
