GRD WRX Stage 2 - 324.8BHP / 295ftlb Torque Running Millers Octane Boost (+2Ron) And Shell Optimax Fuel

This car has the following Packages installed.

GRD WRX Stage 2 Tuning Package With Optional Extras

VF34 Turbo - The IHI VF34 is a roller bearing turbo as used found on the STI JDM models and the prefered choice for group N rallying due its fast spoolup characteristics.

GRD 2.5" Straight Thru' De-Cat Stainless Steel Exhaust System - Optimum gas flow and minimal exhaust back pressure is essential for high power. Exhaust system design parameters immediately after the turbocharger are critical not only for outright performance, but for optimum torque and turbo response. Free Flowing Catalytic Converters to suit this exhaust are available.

Free Flow Air Box Panel Filter - High performance replacement for the original panel air filter. Constructed from a cotton weave which increases air flow by upto 40%.

Syntek Motorsport Fuel Pump - A crucial part to any engine modifications, is the ability to reliably supply your engine with enough fuel. This pump directly replaces the standard unit and has the ability to supply 2.25 litres per minute @ 5 bar pressure. The standard pump generates 1.1 litres per minute @ 5 bar.

EcuTek ECU - We use EcuTek software to reprogram your ECU via the diagnostic port of the car. We retain all the car's clever electronics but re-map ignition curves, fuel maps and the closed loop boost control system. The ECU remains programmable so if in the future something needs to be changed then we can. The only way to tell that that either conversion has been performed is to drive the car. There are no visual clues. Even the Subaru diagnostic tool does not show that the ECU has undergone brain surgery.

Rolling Road Tested - Our Dyno Dynamics chassis dynamometer measures engine power via the driving wheels in an accurate and repeatable method. Your vehicle's dyno runs are recorded in real time, and printed out in full color for your records.


Optional Extras

STI Top Mount Intercooler - As Fitted to 2001 - 2005 STI. The STI Intercooler's larger surface area generates a lower intake air temperature allowing greater ignition advance and more power.

STI Fuel Injectors - They are 550cc and will improve your fuel delivery for high safe horsepower when used in conjunction with one of our Fuel Pumps.

GRD Stainless Steel Exhaust Manifold And Turbo UpPipe - Made from high grade stainless steel pipe work, flanges and smooth flowing joining faces thus removing and kind of gas flow restriction. This results in an increase in torque, engine response and a smoother delivery of power.

Exhaust Downpipe Heat Wrapped - This serves 2 purposes. To reduce heat soak into the engine bay and to keep the internal pipe wall temperatures up to aid the removal of waste gases through the exhaust system.

Turbosmart Blow Off Valve - Features the unique variable exhaust port system resulting in superior venting of excess pressure, a popular choice for the street. Fully adjustable via Turbosmart's unique Quick Wrist action (no tools required). Supplied with full fitting kit (where required). Easy DIY fitment.

DEFI Guage Kit - Includes Oil Temp Guage, Oil Pressure Guage, Boost Pressure Guage and Mounting Pod.


GRD Stage 2 Handling Package With Optional Extras

Whiteline Control Springs - Whiteline Control Springs are between 15-50% heavier in rate than standard to deliver a reduce squat, reduced body roll on turn and a reduction in braking nose dive will provide a pleasing, flatter squarer look on the road. Lowering height of around 25mm. Complete set, Front and Rear Springs

Whiteline Adjustable Front Anti-Roll Bar 22mm - This is the 22mm Front Adjustable Anti-Roll Bar from Whiteline for those wanting to play with the roll bar stiffness. Their objective is to reduce sway, or bodyroll, and stabilise a vehicle under lateral (cornering) forces.

Whiteline Adjustable Rear Anti-Roll Bar 24mm - This is the 24mm Rear Adjustable Anti-Roll Bar from Whiteline for those wanting to play with the roll bar stiffness. Their objective is to reduce sway, or bodyroll, and stabilise a vehicle under lateral (cornering) forces.

Whiteline Anti-Lift Kit - Whiteline Anti-Lift Kit (ALK) is designed to add 0.5 deg static positive castor to both front wheels while introducing a substantial amount of front anti-lift. The anodized alloy mounts coupled with the low compliance polyurethane bushings oppose front lift under acceleration while delivering up to +1 degree more positive caster. This leads to superior traction, reducing understeer allowing more power, faster acceleration and cornering. The additional static caster coupled with the new firmer bushings, deliver more dynamic caster dramatically sharpening initial turn-in response, forcing more consistent alignment angles through the corner allowing higher exit speeds.


Optional Extras

Whiteline Rear Drop Links - These forged aluminium links reduce flexing and therefore effectively increase the rear roll bar stiffness; this helps reduce any natural tendency to understeer.


GRD WRX Stage 3 Brake Package

AP Racing 355mm Formula Kit Front - 6 Pot AP Brakes make an enormous difference to the Impreza's ability to shed speed quickly and in complete control under even the harshest of conditions. If you're into track days or fast roads then the AP Formula Brake Kit is an absolute must. Developed through technology gained working with championship winning F1 Teams, new Formula Performance Brake Kits are the ultimate brake upgrade. 18" Speedlines are required to clear the caliper.

EBC Red Stuff Ceramic Pads Rear - This is a truly impressive fast road pad for repeated heavy braking. It emits far less dust than semi-metallic pads and has been proven to stop a saloon car 13 metres quicker than OEM pads from 100mph/160kph. Features EBC Brake-InTM surface coating which conditions rotor surface and accelerates pad bed-in.

EBC Turbo Groove Discs Rear - The wider slot actually draws cool air across the pad surface keeping pads and rotors cooler. They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale and become ineffective in our opinion. The blind drilled holes break down surface gases when braking from speed but do not weaken the rotor cross section as can happen with through drilling, thereby lessening the chance of rotors cracking over time and heavy use.

Goodridge Hoses - These race-bred brake lines are constructed from the finest quality hose, consisting of PTFE inner and stainless steel overbraid. They eliminate sponginess under heavy braking and increase braking efficiency while being abrasion and corrosion resistant.

AP 600F Brake Fluid - AP 600 Fluid has been developed for racing applications where higher than normal temperatures are being experienced and the ultimate in brake fluid performance is required.
