Hey guys, doing some planning for a bigger turbo, as the 7668 is running out of breath. It's a stock bottom ls1, 317 heads, tick stage 2 turbo cam, ls6 intake. T56 with 3.42 gear, mostly street car. Max future goals would be ~800rwhp. I have 2 questions

1. .96 or 1.15 ar? Turbonetics 7875

2. Will a divided exhaust housing work fine on an open t4 flange?

Thanks for the help, Logan

I'd go with 1.15 not sure about the divided exhaust but I don't see why it shouldnt.
I had ST80 1.15 ar 83mm turbine with my old 347ci spooled awesome and pulled all the way to 6800rpm

Spoiling won't be an issue so go with the biggest one.
