The HD7582 Street Turbocharger from Forced Performance is a great turbo for stock to mildly built V8 Engines (LSx)
With its 75mm compressor inducer and 82mm turbine exducer, you can expect to see between 500 and 800 horsepower from a single turbo application. We offer this in two different T4 turbine housings, a 1.10 A/R and a 1.25 A/R. We recommend a 1.10A/R for stock or smaller motors, i.e. a 4.8 or 5.3, while the 1.25 responds very well on a larger or more built motor such as a 6.0 or applications that use a looser converter or have a larger cam.
