XS-POWER 78/75 BILLET T4 TURBO
600–1125HP • 3" V-BAND • OIL-COOLED • LS V8 MONSTER
Ultimate Performance Turbocharger for LS1 • LS2 • LSX • 4.8L • 5.3L • 5.7L • 6.0L • 6.2L
PRODUCT OVERVIEW
Introducing the newest, most powerful drop-in T4 turbocharger for high-horsepower LS-based V8 engines. This 78/75 Billet Turbo delivers massive airflow, reduced backpressure, faster spool than the old 76/65 units, and the strength to support **1125+ HP** with proper setup.
Most turbos in this class still use a small 65mm turbine wheel — a MAJOR choking point. This upgraded unit features a **75mm high-flow turbine wheel + 78mm billet compressor wheel** to keep exhaust backpressure low and prevent overspeeding the CHRA.
Perfect for single-turbo street builds, drag applications, or twin setups running into the 8’s. XS-POWER / BPM has been testing and selling this exact unit for the last year — and it has quickly become one of the hottest choices in the V8 single-turbo world.
