GRD WRX Stage 3 - 343.3BHP / 320ftlb Torque Running Millers Octane Boost (+2Ron) And Shell V-Power Fuel

This car has the following Packages installed.

GRD WRX Stage 3 Tuning Package With Optional Extras

GRD Race Exhaust System - Weighing in at just 16KG`s this exhaust is possibly the lightest on the market - a massive 40% lighter than the standard system. Using fully slip jointed stainless steel construction this exhaust gives exceptionally good flow as it utilises a very straight and smooth exhaust path.

Specification is as our Drag Exhaust System but instead re-vents exhaust gas from the screamer pipe back into the mainpipe reducing noise levels to help comply with both track and road regulations.

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.

De-Cat Up Pipe - Unlike the WRX, this Up Pipe has no restrictive Cat increasing flow and compliments our 2.5" Stainless De-Cat System.

Hyperflow Top Mount Intercooler - At nearly 2.5 times the volume of the standard intercooler, the Hyperflow Top Mount Intercooler is absolutely the largest top mount intercooler that is practical to install in the late model STI vehicles.The larger surface area generates a lower intake air temperature allowing greater ignition advance and more power.

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.

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.

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

Exhaust Downpipe & Manifold 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.

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.

GRD Cold Air Intake - By eliminating the standard airbox resonator and snorkel we are able to source cold air directly from custom vents in the front foglight cover. This helps to dramatically increase airflow to the standard airbox, lowering inlet temperates and in turn give a significant increase in both power and torque.

This package does require STI foglight covers, however we can offer these as an option on most WRX models.


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.
