This turbo will surprise you at how well it runs! We have torture tested it for longevity, proven its capability on the dyno and at the Race Track. The 1.0 A/R Housing is intended to cool your egts above 3000 RPMS, for dedicated tow rigs and daily drivers the .84 A/R housing will provide a quicker spool and cooled EGT’s below 3000 RPMs.

This is a journal bearing turbo with a KC Turbos 300x turbine wheel, modified to fit inside a drop in ready Super Duty turbo.

**EXHAUST BRAKES: We get asked a lot about exhaust brakes and if they work with our turbos. We have found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues. These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aide in braking. This can be hard on a turbo and motor and is not recommended. It will be up to the customer to verify fitment and functionality.**
