KC Turbos Gen 3 Stage 1 Conversion Kit - 1994-1997 Ford F-Series

KC300x Gen 3 Stage 1 OBS Conversion Kit – 1994.5–1997 Ford 7.3L Powerstroke

Supports: Up to 205cc/30% Injectors

If you're looking for the ultimate bolt-on turbo upgrade for your OBS Powerstroke, the KC300x Gen 3 Stage 1 Conversion Kit delivers modern turbocharger technology without sacrificing the factory OBS layout.

Designed specifically for 1994.5–1997 Ford 7.3L Powerstroke trucks, this complete conversion kit allows you to install the KC300x Gen 3 E99 turbo while retaining your factory OBS downpipe and Y-bridge. Unlike piecing together a conversion yourself, this kit includes everything required to make the installation straightforward and truly bolt-on.

The result is dramatically quicker spool-up, lower EGTs, increased airflow, and industry-leading reliability—all while supporting injector sizes from stock up to 205cc/30% hybrids.

🛠️ Why Upgrade to the KC300x Gen 3?

The KC300x Gen 3 represents years of research and development focused on improving every weak point found in the factory GTP38 turbo.

Compared to previous-generation drop-in turbos, the Gen 3 offers:

• Faster spool-up

• Lower exhaust gas temperatures

• Improved throttle response

• Increased airflow

• Higher sustained boost

• Significantly improved reliability

The redesigned compressor and turbine housings utilize modern flow paths, anti-surge technology, and optimized volute geometry to produce more usable power across the entire RPM range.

💪 Built for Reliability

The KC300x isn't just designed to make more horsepower—it's engineered to survive it.

Major reliability upgrades include:

• 200% larger thrust bearing system

• Larger journal bearings

• Thick-shaft turbine wheel

• Cast iron integrated backing plate

• Steel thrust insert

• Reduced housing deflection under extreme heat and boost

These improvements make the Gen 3 one of the strongest journal-bearing drop-in turbos available for the 7.3 Powerstroke.
