Industrial Injection 93-02 Dodge Compound Kit w/ S474 (Add Turbo to Phatshaft Turbo) - Spec Yr/Trans

This Industrial Injection compound turbo kit is built around an S474 turbocharger, designed to work in conjunction with your existing Phatshaft turbo. This setup is for 1993-2002 Dodge trucks and is specifically configured to add a second turbocharger, creating a compound setup that can significantly improve airflow and power potential. The S474 turbocharger features a 74mm inducer diameter on the compressor side, which is a popular size for those looking to increase airflow without going excessively large. This kit is intended for those who already have a Phatshaft turbo installed and want to step up their forced induction system.

The core of this kit is the S474 turbocharger itself, a well-known unit for its robust construction and ability to handle increased boost levels. When paired with your Phatshaft turbo, it creates a compound system where the smaller turbo spools quickly at lower RPMs, and the larger S474 takes over at higher RPMs. This staged approach helps reduce turbo lag and provides a broader, more consistent power band across the RPM range. The kit includes the necessary components to integrate the S474 turbo into your existing setup, allowing for a more comprehensive forced induction solution.

This compound turbo kit is a substantial upgrade for your 1993-2002 Dodge truck, aimed at owners looking to maximize their diesel engine's performance. Please note that this kit is not CARB approved and cannot be shipped to California. It is recommended to consult with a professional installer or refer to the manufacturer's detailed installation guide for specific fitment and setup procedures, as compound turbo installations can be complex and require careful attention to plumbing and exhaust routing.
