Improve your 7.3 Powerstroke's performance with the KC300x Gen 3 Stage 1 turbo. Built around a 3.5" ported housing with a redesigned 7x7 SXE-style compressor wheel and a thick-shaft SXE-style turbine wheel, this turbo combines quicker spool than the old 0.84AR with more airflow than the old 1.0AR. The redesigned bearing housing fits 200% larger thrust bearings and upgraded journal bearings on an integrated cast-iron backing plate for stability at elevated boost and HP levels.
