 IHI VF48L/Stage 2 Turbo Single Scroll

With an upgraded compressor wheel and reinforced bearings, capable for an added extra 20-30kw over the stock VF48.

Cylinder 4 cooling has long been a known issue on the EJ Family of Subaru engines. The nature of the water passageways around this area means a lack of cooling can lead to an increase in the temperatures around this cylinder.

RCM's simple solution to this problem lies in our easy to fit complete kit. Billet fittings are banded in place on our custom 90 degree Samco silicon hose, which you simply fit into the unused port at the back of the block at cylinder 4's location. This is then tee'd into the water matrix pipe directly above using the supplied HiGrip stainless steel fittings. The billet barb fitting is of the correct diameter to allow the right flow rate around cylinder 4 to cool without over cooling, and the 90 degree pre-formed Samco hose ensures that this flow is maintained without disturbance from potential kinks in the pipework.

Suits all EJ Engines

MAC valves are used world-wide by many industry leading motorsport brands and workshops and is a brand you can trust.

Mac 35 Series Valve

The MAC 35 series is a direct solenoid operated 3-way poppet valve.  It features a short stroke solenoid, a balanced poppet and powerful return spring.  These features translate into high shifting forces, fast consistent response times, and long life.  Our unique balanced design means virsatility in piping – the valve can be configured as a 3-way or 2-way – normally closed or normally open or can be used for vacuum, divertor or selector applications. 

Features:

• Genuine MAC Solenoid Operated 3-Way Valve
• Turbosmart Silicone Vacuum Hose
• Nickel-Plated Barb Fittings
• Vehicle Specific Black Finish Bracket
• Vehicle Specific Plug-and-Play Wiring Harness

Tuning Notes:

Because this upgraded solenoid affects the way that your vehicle controls boost, it is always recommended that you consult with a tuner immediately following installation. It is not recommended that you drive the car in a way that builds boost without doing so. If you have any questions, don't hesitate to get in touch with us directly!

Omni Power USA 3, 4 & 5 Bar MAP (Manifold Absolute Pressure) sensors use state of the art bipolar op amp circuitry with thin film resistor networks built into each micro chip.

Pressure changes are calculated on a true linear 0-5 volt scale via a specially designed silicon pressure sensor that also compensates for temperature changes. The unique ability to compensate for temperature changes allows the Omni Power USA 4 Bar MAP sensor to remain a minimum of 99% accurate from 32 degrees F to 180 degrees F through out its range of scale.

With the true linear pressure vs. voltage scale there is never a need to re-tune at different altitudes as with other sensors. Competitors sensors on the market don't have true linear scaling which can cause your engine to go out of tune with elevation changes, often resulting in idle problems, poor drivability, and catastrophic engine damage. 

Key features:

• Cases are designed to withstand in excess of 130 PSI without leaking
• -40 to 260 degrees Fahrenheit temperature operating range
• Able to respond from 10% of the pressure scale to 90% of the pressure scale in .001 seconds (the fastest response time of any MAP sensor on the market).
• Automatic temperature compensation.
• True linear scaling for perfect drivability at all boost and vacuum levels.
• Compatible with all aftermarket engine management systems.
• Minimum of 99% accurate over full scale range under all conditions including temperature, altitude, and humidity changes.
• Allows smoother engine operation, higher boost levels, and better drivability than competitors turbo MAP sensors.
• Direct plug and play for an easy install and an OEM look. Dimensionally identical to the stock MAP sensor.
• Each sensor is hand assembled, pressure, and function checked in the USA for unparalleled quality control prior to shipping.

*Please note vehicle will require tuning after installation*

Applications: Subaru WRX 2001-2014 / STi 01+
