Help me pick a turbo I have a 2011 silverado with a 6.2. The Engine is 378ci forged lower and Texas speed 255cc heads. 358 intake flow and 235 exhaust. custom from tick performance! Martin spec it for me. 230/231 598/698 115. 9.7.1 compression stock truck intake and tb. My turbo setup now is s480/92 turbine 1.25ar. 3.5 down pipe. At 13lb of boost it made 750 rwhp 93 October and meth. At 15lb of boost I tested the back pressure it's 36lb. Want a turbo to break 1000 rwhp and have a little room to grow. Turbo I'm look at so far billet BW84/96 1.32ar. Precision 88/91 precision pt91.5. Gt5088. Ok turbo guys what turbo and spec. thanks guys for the help!!.

Thank you for the reply. I like the Borg turbos. I just not sure about the difference the 96 in a T6 housing will make in my BP. I when from a 83 wheel to a 92 wheel in the T4 housing and it made a little difference. I hope the T6 housing will flow alot more.
