Here are all the photos I could find on it, but @DOC_Race will be putting out a big twin turbo kit for the S55.
I’m told it will be ordered with a variety of turbo sizes and is very customizable from 700hp to 1500hp. It will use Garrett ball bearing turbos with stock like look and fit. Will be able to retain any factory fit air boxes and exhaust. The kit should be 100% bolt-on ready and available by the beginning of 2019.
