Thanks. I have been torn between a single or twin. I am looking for a 1000hp at the wheels. I talked to a buddy and he said 2 bw s366. I'm lost in this as its my first ls and first turbo. I'm a old school bbc with the gas. Want to buy once not 3 or4. Thanks guys

Put em both on there and be a good roll race car lol. Really need more cubes to spool them good. I'd run one and pin the wastegate and just see what you can make with one. My 75mm borg is making over 800 on my stock ls1 with cam. And not even maxed out. Maybe could see 900rwhp with a single precision like you have on a 5.3. I don't know how the precision compare to Borg on power comparability.
Are they the 7675 precisions? Twin 76's would be way too much turbo for those cubes in my opinion. Like said above, just run a single and have a backup. Or search for twin 60's.....

I have two NEW! Precision 6176E MFS Turbos. These have never been run and are brand new. They are 61/76e .68ar vband hook up t4 flange. I am looking to get $1200 for both shipped. Perfect for a 5.3.
When it was stock I spun it to 7200. That was a Ptc 9.5 that would stall to 4400 then flash to 6000 in a 80E. Its built now and been pushed it to 32psi. converter makes or breaks a auto setup as far as spooling.
