This is our standard turbo kit for the S58, built around an H cover housing turbo of your choice. Every hot part, fitting, and adapter is fabricated and machined in-house, we only outsource what we absolutely have to, and even then we test it to our own standard before it goes in a kit. This isn't five vendors' parts bolted together and called a kit, it's a kit we built to work as one system.
We don't put a WHP number on this kit. How far you can push an H cover turbo comes down to your tuner and the rest of your combo, not a number we slap on a product page.
This kit ships out ready to install, everything needed to run correctly on an S58 platform, no guessing on fitment.
