Hello all. This is an update to my Previous post on the LS3 swap, with rear mounted turbos. Turns out the STS turbos were not putting out the power they claimed they would, so we went ahead and pulled them off. We installed the Precision Turbo 6266's with the V band stainless turbine housings and dual ball bearing center sections. The installation looks fantastic, and the sound is amazing. We added mufflers to bring the noise level down a bit.
