5.3 turbo'd guys come in
What turbo/s are you guys running on your 5.3s?
Im about to pull the trigger on a ON3 kit for my 2010 Sierra and im think of going with a BW turbo instead of the newer ON3 78mm.
Its a stock bottom end 4th gen 5.3 which will get the factory 243s ported, plan on running on E85 and my HP goals are around ~600RWHP~ but later on go higher. I know the newer ON3 78 can get the job done but I was looking for other options. Nothing against the ON3 78 just looking to see what some of you guys are running.
Thanks guys.
Suporting mods will be 4.11 gears, tru trac, traction bars etc etc

Slowest turbo build ever!

Like Atomic said, something right around the 76mm compressor size should be perfect for that. Ive got a 70mm waiting to go on mine, but I sized it more for DD/towing duty than for highest performance.
I would also considering dropping down from a 4.10 to like a 3.73 or 3.42 gear. It'll help load the turbo up better.
You also really don't need to get the heads ported. With the right turbo/cam/gears/stall you should have no problem hitting 600hp without digging too far into the motor.

From Experience in my RCSB from several years ago..
..... 12psi turbo 5.3...4l60e...and 4.10's ran a 12.25@114
......12psi turbo 5.3...4l60e...and 3.23's ran a 11.61@121
conditions almost identical...and the only thing i changed was gears and the truck became a completely different animal... so i disagree with the disagreement but to each their own.
