We created the Gruppe-S Power Package #2 to satisfy the needs of WRX owners that are simply not satisfied with a moderate increase in power.  Our economically priced power package #2 will turn a factory WRX into a true street-king while maintaining every-day drivability.  Our Power Package #2 removes the restrictive factory turbo and replaces it with the much larger IHI VF-34  turbocharger unit found on the 287HP Rally-bred Japanese version WRX STI-RA models.  This turbo features larger turbine and compressor housings as well as a new ball bearing design that allows for much more power in the upper RPM's without sacrificing the spool-up of the stock turbo.  Along with this larger turbo includes larger WRX STI 565cc injectors and a 255 lbs/hour Walbro fuel-pump.  The additional fuel flow will keep your engine properly fueled up to the 400HP range.  To manage the larger turbo and fuel system, we provide a pre-tuned ECUtek reflash for your factory ECU.  Combined with our power package #1 this setup is good for 350HP on your WRX. Add a larger top mount or front mount intercooler, and your properly tuned WRX will put down a whopping

POWER PACKAGE 2 Includes:

*IHI VF-34 Turbo -  The IHI VF-34 Turbo is found on the limited production Subaru v7 WRX STI-RA (GDB).  This turbo is differentiated from the VF30 through it's more advanced bearing design.  The bearing design allows for much quicker turbo spool-up (depending on tuning, 300-500+ RPMs over the VF30), while retaining the power capabilities of the VF30.  The VF34 is capable of 350+ HP (~300+whp)  This turbo is a direct bolt-on for all GC8, GDA, GDB EJ20 turbo engines.  This is an excellent replacement turbo for those looking for substantial power gains while maintaining streetability.

*Genuine Subaru 565cc STI Injectors- The STI 565cc injectors are OE Subaru high-performance injectors found on the high horsepower STI, STI-RA, and S202 Impreza models.  These injectors are factory rated at 525cc but because of the common "under-rating" system of Japanese manufacturers, these injectors have been independently tested to flow 565cc.  We recommend the use of these injectors for applications of 240whp-300whp.  A very good compliment for all IHI VF-series turbos.

*Warlbro GS342 High Pressure Fuel Pump - The Warlboro Fuel pump is a must have for high HP applications.  The Warlboro fuel pump flows at 255liters/hour and can support applications upwards of 750+HP.  This is a must have as a replacement for your factory 140 liter/hour pump.  This pump will increase you fuel pressure slightly. 

*Ecutek Reflash for the factory computerr - Our Ecutek reflash alters your factory fuel, ignition, and boost parameters to accommodate for the larger turbo and increased fuel.  Our reflash is expertly tuned to allow for a fine balance between maximum power, driveability, reliability, and fuel economy.  This reflash retains the factory ECU's flexibility in adapting to rapidly changing conditions, well designed base maps, and the reliability of a factory built computer.  The Ecutek reflash is perfect for customers seeking a plug-and-play solution without sacrificing reliability and driveability.*

*The Ecutek reflash requires that you send in your factory ECU.  If you need help removing your factory ECU please visit our ECU removal FAQ here: http://www.gruppe-s.com/Subaru/subpackage/LinkECUinstall.htm  If you overnight ship us your ECU (at your expense), we will overnight ship it back to you on the following business day FREE OF CHARGE!
