Our Stage 3 Power Package begins by swapping the stock 16GL turbo for the much larger Garrett GT3071.  The Garrett GT3071 is a Garrett medium frame turbocharger featuring a T3 turbine wheel and a 71mm compressor wheel housed in a ball-bearing center cartridge.  The ball-bearing center cartridge ensures optimal turbo response and spool up, while the much larger T3 turbine and 71mm compressor substantially increases the power potential of your Evolution. 

The larger GT3071 turbocharger will increase pump-gas potential by over +30whp over our Stage 2 package, with a overall horsepower increase of 110 to 115 whp (~145HP) over stock.   The GT3071 was selected as the optimum Stage 3 turbo because it provides a substantial power gain without sacrificing turbo response, spool-up, and everyday driveability.  Furthermore, it does not require the upgrade of the stock intercooler, hardpipes, or any other components other than the existence of the Gruppe-S Stage 1 and Stage 2 power-packages. 

In terms of additional components only the Helix 720cc injectors are required to supplement the additional fuel needed.  The ATP GT3071 kit WILL replace your factory downpipe. 

And of course substantial tuning is required for proper operation, therefore the use of the Gruppe-S Reflash is mandatory.

Another key benefit of the GT3071 is that this turbocharger is a monster with higher octane gas.  With the addition of 100 octane gas, the GT3071 is capable of putting out an additional 40whp OVER 91 OCTANE.  This means a 480HP Evolution by simply adding 100 octane gas and recalibrating the computer.  Gruppe-S Reflashes are available to accommodate 100 octane maps (please contact us for details).

The Gruppe-S Powerpackage 3 is fully compatible with all 2003+ Lancer Evolutions including the MIVEC EVO IX.   

POWER PACKAGE 3 INCLUDES:

ATP GT3071 Turbo Kit - The ATP 3071 is a direct bolt-on turbo kit for your Lancer Evolution VIII & IX       Features       - ATP GT3071 Turbocharger       - Tial 38mm External Wastegate       - Intake       - 76mm Downpipe       - All oil lines, hoses, clamps, etc.

Helix 720cc Injectors - The Helix 720cc Injectors are custom made to Helix specifications by Denso Japan.  These injectors feature a spray pattern suited to the 4G63 as well as other minor changes.       Features       - 720cc Design       - Custom 4G63 spray pattern       - Superior to "modified" injectors such as FIC

Gruppe-S Reflash - With our years of experience tuning high-performance race vehicles such as the WRX US-Touring Car, Grand-Am car, as well as numerous Rally and drag cars, we have perfected the art of tuning a high performance vehicle and extracting the maximum power without compromising safety. Our Power-Package #3 reflash, is developed exclusively to be used in conjunction with our Power-Package #3 components and is required for our Power Package #3 components to work properly.  This map is developed through extensive road and dyno-testing and works by adjusting boost maps, ignition maps, fuel trims, and various other parameters to maximize the effects of more aggressive cams and the high-flow fuel pump.  Built in are ECU safety features such as knock control and fuel trim, creating a safe and reliable tune.  Gains of over 110whp are achieved.  Our map is designed for California 91 octane.* We offer a map loading service if you do not have technical knowledge to load your own ECU maps. *California 91 octane is generally regarding as the worst 91 octane in the country.  Therefore our 91 octane map is compatible throughout the country as long as 91+ octane gas is used.  You may see additional horsepower gains if your car is fine-tuned for higher octane gas.  We also offer a 100 octane and alcohol injection map for the Stage 3 car at additional cost.

1. Gruppe-S Loading Service - You send us your ECU, we will load in the Gruppe-S Stage 1 Reflash for you and return your ECU to you via overnight shipping. 

2. Software Only - If you purchase the software only, you only need to provide us with your ECU number and VIN number.  We will send you an electronic copy of our the Gruppe-S Stage 1 Reflash specifically encoded for your ECU.  You will need a general understanding of reflashing techniques and you MUST possess the hardware to be able to reflash your vehicle.  If you do not know how to reflash your own vehicle, please choose option #1.
