Quick question about GT35's
 

How much would I give up with a T3 .82 housing compaired to a t4 .82 housing or tial stainless v-band .82 housing. It would be twins on a built 6.0 & 4l80, street driven a lot but want to get close to 1Kwhp, if possible, when I want. I ask because I need to replace my current turbo on my V-6 car (62-1 stg5 .63ar turbonetics) and would like to get one of the GT35's now and pick up another later (I have a couple years to buy parts for the 6.0 build, plan to throw everything together for a 40th birthday present to myself). My current hot side has a T3 flange, but I will weld a new one up if it's worth it. I already have to cut up my downpipe to get rid of the gay 5 bolt ford flange, so it will not be all that big of a deal if needed. Thanks for your time and thoughts.

0.82 T3 housings will support 1100 rw on a twin GT35R setup.

Thank you very much. And coming from one of the first v6 car builders, nice.
