Already bought two turbos, now I think I want to go bigger
I got a darn good deal from Louis at LG Motorsports for two brand new Precision 61mm T3 turbos. They have a 76mm exhaust wheel with a .82AR. Rated for 680hp each. I've got the motor being put together at the machine shop now. Iron block forged 370 with ported LS2 heads. 9.3:1 compression. It's going in a 4100lb GTO with a TH400 and a 3200 stall. Going to be using C6 manifolds flipped backwards. 2.5" or 3" charge pipes and 3" downpipes. Mostly for strip duty but some street time on nice days.
Should I keep the turbos I have or go bigger? If bigger, then what?

The rule of thumb I heard(doesn't mean it's right, lol) is that you don't double the two turbos output. You only get 80% or so from the second. That's still 1200hp, but I'm concerned the T3 flange will hold me back. This is my first turbo build, so I'm kinda learning as I go.

Well if you decide to sell them shot me a PM and i might take one off your hands . But on a side note should be one hell of a build. Keep in mind you are spliting the air going into the turbos vs one. Some of us are running smaller single turbos
