If you are a do-it-yourselfer, Gale Banks Engineering offers the complete Twin-Turbo kit to fit a GM small-block V-8 engines. Installation by a competent mechanic can be completed in one weekend. The Banks Twin-Turbo system offers tremendous performance and economy in a classic package from the company that never compromises.
What it fits
The Banks Twin-Turbo SBC product line is not based upon a specific vehicle fitment. It is based upon a Chevy small block or a comparable Dart small block engine with an aftermarket EFI fuel and ignition system. Give us a call, tell us what you're looking to do with your engine project, and we'll tell you exactly what you can expect from Banks Power!
The massive amount of air needed to make 800HP is fed to the engine via a Banks-designed pressure chamber with an integral shuttle valve and a billet throttle body. Both sit atop an Accel Pro-Ram manifold, which is CNC port matched to fit our heads. The high port runners optimize air movement and help broaden the torque curve.
Fuel and Spark
Fuel Injection and spark management is provided by Accel DFI. Their proven system, combined with the thousands of hours logged on the Banks dynamometers plus on-the-road testing, has resulted in a truly solid calibration, which works equally well with manual or automatic transmissions. Idle quality, drivability, mileage, and wide-open throttle have all been addressed with this sealed calibration. The calibration is designed to provide safe fuel and spark management with a minimum of 91 octane fuel for everyday driving, and 100 octane fuel for maximum boost situations.
These compact, high-flow manifolds were designed by Banks for the ultimate in fit and long-term durability. Their unique design resists cracking and distortion while providing the best turbo and wastegate placement for ease of installation.
The Banks BigHead® Wastegates are designed for a flat boost curve resulting in an awesome power transition. The high-gain actuator allows for quicker spool-up and less boost creep. The stainless steel body withstands the high temperatures, ensuring a long and reliable service life.
The high-flow turbochargers, built by Banks to our own strict specifications for optimum performance, deliver outstanding power from their compact frames. With our precision-balanced inconel turbine wheel and shaft assembly, the assurance of durability and reliability is never in question. Driving is a smooth, pulse-pounding power fest that gives you the "nailed back in your seat" thrill you'd expect from Banks. The efficiency of our compressor design helps to reduce inlet air temperatures to acceptable levels, eliminating the need for an intercooler.
When customers receive the Banks Twin-Turbo system, it includes an engine wiring harness, which they can customize to their application. Included with the system are exhaust flanges, wastegate flanges, pressure regulator, and fuel pump. An owner’s manual, installation instructions, and dyno sheets are also supplied with the package. Gale Banks Engineering will also work with the customer to create that perfect look for their application. Polishing, chrome plating, anodizing and color coordination can all be worked out to create the desired finished product.

For the first time (that we're aware of), a Banks Twin Turbo engine finds a home in a motorcycle, and not just any motorcycle, a three-wheeled one at that!
How a turbocharger works, and why a VG turbo rocks, is covered by Gale and Jessi from Xtreme4x4.
“Among the few companies that offered tuning combined with airflow, only Banks offered a system in which all the components are engineered to work together.”
