Want a serious boost in the power of your Toyota 86 or Subaru BRZ?

The Stage 5 Upgrade package will literally supercharge the power of your engine!

A Stage 5 Upgrade Package is based around the professional fitment of the highest quality supercharger kit on the market and  an effective Tune Package & custom ECU calibration.

We've tried many supercharger kits on these vehicles and the Harrop TVS1320 come out on top for performance, quality and aesthetics.

How does the Stage 5 Power Package increase power?

The fitment of a supercharger adds boost to your standard engine, greatly increasing the volume of air entering the engine. This increased air-flow is matched with the correct amount of fueling and a custom ECU calibration to produce significantly more power through the entire powerband.

By design, a supercharger adds additional power in a linear fashion, which excentuates the factory rev-happy nature of these engines. The result is an engine that drives like stock, just with significantly more power.

With a supercharged engine setup, we apply a custom tune calibration to suit your exact setup, ensuring this caters to your specific performance goals & the age/condition of your engine.

Additionally, the factory ignition timing control strategy can create a slightly inconsistent and slightly jerky power band with a significant torque dip. A PBMS tune package will reduce this dip and give you incredibly consistent, smooth and safe power.

Note: This is a physical service that must take place at Possum Bourne Motorsport in Pukekohe, Auckland. We require the vehicle for approx. 4 business days to complete this service thoroughly and often have a 2-4 week lead time so, please contact us prior to purchasing if you would like to confirm a time. If no time is confirmed prior to purchase you may not be able to get the date you required.

Benefits Stage 5 Power Package

  • Increased power and torque - typically +75kW / 60% more than stock through the whole power band. See previous results here.
  • Improved throttle response
  • A smoother power band and optimised drivability 
  • Tuned for current NZ fuels making for a safer and more reliable tune for modern fuel. See fuel rating information.
  • Removal of any fault codes for removed or disabled systems (typically emission control related, catalytic converter in the case of an aftermarket exhaust fitted)
  • Removal of any speed cuts (please request when dropping off)
  • Custom calibration on our in-house dyno to suit your engine, engine condition and any specific modifications or requests you may have. See the PBMS 9-Step Tuning Process.

Compatibility

This is compatible with Toyota 86 and Subaru BRZ models from 2011 to 2021 only. We can offer this service on a huge range of vehicles, contact us if you can not find your vehicle using the vehicle selector.

Recommendations & Upgrade Options (Not included in price)

  1. We recommend completing any other modifications you desire BEFORE a PBMS Tune Package 
  2. We recommend the vehicle is serviced, maintained and in good working order prior to the PBMS Tune Package. PBMS can complete any additional work as required. PBMS can perform any service work required. If you are going to have the oil changed else-where, please contact us to choose the correct oil for a high-load performance application. These engines require a thicker oil if being used in a motorsport application due to oiling issues. 
  3. Consider upgrading to an EcuTek tune for additional tuning features. Click here for pricing.
  4. EcuTek Race Rom for features such as launch control, flat foot shifting & anti-lag (Included free of charge if EcuTek licence purchased with Stage 1 Package!). Additional Bluetooth ECUTEK ECU Connect kit can be used to adjust settings and monitor performance.
  5. E85 Flex Fuel upgrade package - includes installation and allows flex-fuel capability on the standard ECU, making the most possible power with E85 fuel.
  6. Before dyno run to give you a true power comparison against your stock power level. Click here for pricing.
  7. We recommend fitting a baffled sump if using this extra power on a race-track or pushing hard on the back-roads to prevent engine damage. Click here for options
  8. We recommend fitting an upgraded radiator and the addition of an oil cooler if using this extra power on a race-track or pushing hard on the back-roads due to cooling these vehicles are prone to having. Click here for cooling options.
  9. Oil catch can or Air Oil separator to capture the oil vapours that occur as a result of the higher power levels produced. Click here for options.
  10. An exhaust and header system will significantly reduce engine back-pressure, improving performance and reducing stress on the engine itself.
  11. LVVTA certification and the fitment of driveshaft loops will be required to keep this vehicle road legal. Contact us for further information.  

Next steps (Not included in price)

Once you get a taste for power, you may find yourself wanting even more! We have developed a series of upgrade stages to allow you further performance upgrades. You can purchase the parts online to fit yourself or have PBMS fit the parts for you. Please note that every additional modification that changes the engine flow (intake or exhaust related) or fuel delivery (injectors or fuel pump) requires a re-tune to suit.
