GRD STI Stage 3 - 388.9BHP Running Millers Octane Boost (+2Ron) And Shell Optimax Fuel

This car has the following Packages installed.

GRD STI Stage 3 Tuning Package With Optional Extras

APS SR40 Turbo - Specialist performance turbocharger with performance characteristics to suit modified engines of 2.0 - 2.2 L capacity. The SR40 turbocharger has the capacity to supply air to produce 440 hp with good turbocharger response characteristics.

GRD 3" 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.

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.

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.

Hyperflow Wing Mount Air Intake - Unlike ram pods which source hot air from under the bonnet, this system delivers cold air from the inner guard for optimum engine performance.

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

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.

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 STI Stage 1 Brake Package

EBC Red Stuff Ceramic Pads Front & 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 Front & 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.
