Banks developed the Quick-Turbo in conjunction with the Holset turbocharger and Cummins Engine companies, to eliminate sluggishness out of the hole and produce strong acceleration. Quick-Turbo produces massive torque right from idle, achieves a higher peak faster, maintains more boost through the powerband, and doesn't over-boost. Banks' exclusive BigHead wastegate actuator prevents wastegate blow-open by keeping the valve seated at higher pressures, increasing mid-range torque and top-end power. This product is available in three different configurations to best suit your needs: Quick-Turbo with BigHead wastegate actuator, Quick-Turbo w/BigHead & 0-50 boost gauge, or BigHead actuator kit (nuts, clips, hoses, etc. included. Please note: The Quick-Turbo will not fit 2001-2002 models with the HY35 turbo (automatic transmission, 235-hp rated engine). The quick turbo will fit the 2001-2002 models with the HX35 turbo (manual transmission, 245-hp rated engine).
