One of our favorite turbo kits from back in the day was the HKS Twin Kits using GT Series turbochargers. These kits are no longer available, so we decided to release a kit that would make HKS proud, by amping up the game considerably, with ultra-modern turbo technology and a ultra-trick twin v-band mount exhaust manifold.
Our twin kits offer a wide range of power delivery and torque and use only Borg Warner EFR 7163 dual ceramic ball bearing, Ti Beta Gamma Wheeled, Internal blow off valve and boost control turbochargers by Borg Warner.
After working with Geoff at Full Race and BW to determine the best path forward for the SupraStore twin kit, we agreed that the mixed flow EFR 7163 would be the ideal choice. We're looking to produce the most torque and transient response down low of any twin kit ever produced while at the same time offering a compressor map that can yield us power across the entire map. We've achieved this with the 7163 twin kit.
These are the same turbos used in the 2014/15 IndyCar series and are the most robust, low end torque building turbos we've ever seen. They develop torque quicker and come up to boost more efficiently than any turbo on the planet.
We believe this is the ultimate 525-1000HP street twin kit on the market. It spools as good as any single kit capable of making 1000rwhp, but where it differentiates itself is in transient response, torque (bucket loads down low) and the incredible technology wrapped up inside BW EFR turbos.
You can run these turbos as low as 525HP in the twin set-up, so those of you on pump gas can utilize this kit as well.
We only use v-band turbo mounts, external gated systems, as they provide for more power and quicker response on the street and the track, plus are much easier to work with in the tight confines of the engine bay. This is simply the most cutting edge twin turbo Supra kit ever built and it's affordable and robust.
Our hand made turbo manifolds are designed for maximum flow from 3-cylinders that feed each of them. V-band turbo mounts with collectors which are flow designed to provide the best power, torque and boost control designs.
Each manifold is equipped with dual Turbosmart gates for ultimate boost control. We supply the state of the art TurboSmart CompGate 40 Series gates, which are 25% smaller than TiAL or Precision, offer the simplest spring change design and are incredibly temperature resistant.
Highlights of the Borg Warner 7163 EFR Turbos:
First mixed flow turbine ever offered in a performance application. Ti Gamma Turbine Exhaust Wheel offers lowest inertia in any turbo, which results in quicker on boost and transient response (lightweight and robust)
V-Band Turbo Mount with a .85 A/R ratio, perfectly sized for the 2JZ motor and packaging via V-band mounting is ultra-efficient.
Forged milled extended tip compressor wheel technology
Built-in BOV: All EFR compressor housings incorporate an integrated BOV.
Inlet: 2.5" Hose Coupler
Outlet: 2.0" Hose Coupler
Turbine type: Low Inertia Gamma-Ti Turbine Wheel
Turbine Wheel OD: 63mm
Stainless Steel Sand cast Housing
People want to know what turbo does this compare to in power making and response. The answer is two-fold. The Garrett GTX 3076R makes about the same peak HP and Torque as the EFR 7163, but it takes 750rpm more to do so!!
These are shocking numbers. In the dyno graph attached you can see a 7163 vs GTX 3076R and while they make the same peak power, look how much quicker the 7163 comes on boost and it makes a lot more torque quicker too.
This translates into a great driving car on the street with quick spool and a powerful top-end.
