Forced Performance HD7582 S400X Street Turbocharger w/T4 Div 1.10 A/R Turbine Housing

HD7582 S400X Street Turbocharger w/ T4 Div. 1.10 A/R Turbine Housing

The HD7582 Street Turbocharger from Forced Performance is a great turbo for stock to mildly built LS motors.
The HD7582 turbocharger features the larger full size S400 comp cover and billet 75mm compressor wheel and a very high flowing 87x82mm turbine wheel. It is unusual to have the larger 82mm exducer size turbine in the T4 S400 size, typically it is a 72 or 76mm exducer diameter which results in high back pressure. You can expect anywhere from 500whp to 800whp from this turbo in a single turbo application depending on engine size and boost pressure. We offer 2 different size A/R ratios for this turbo, 1.10 or 1.25. You can tailor the response to suit your displacement and converter choice, the smaller 1.10 A/R for smaller engines like the 4.8 or 5.3 and the larger 1.25 A/R for larger engines like the 6.0 or a looser converter and larger camshaft.
The oil inlet is 1/4 NPT. The optional downpipe flange/clamp are set up for a 4" downpipe. It has a conventional T4 S400 Spec outlet flange.
