FAQ
What does a 1.44 A/R turbine housing do?
A 1.44 A/R housing is designed for high horsepower setups, allowing greater exhaust flow at higher RPM while sacrificing some low-end spool.
What is the benefit of a divided T4 housing?
A divided (twin-scroll) T4 housing separates exhaust pulses, improving turbine efficiency and spool response.
Is this compatible with all GT42 turbos?
This housing is designed for Garrett GT42, GT42R, and GTX42R Gen I turbochargers. Always verify your turbo configuration before purchase.
Can this be used for street applications?
Yes, but it is best suited for high horsepower builds where top-end performance is prioritized over quick spool.
