Important Notes on Your Internal Wastegate Actuator

  1. Turbosmart accepts no responsibility whatsoever for incorrect installation of this product which is potentially hazardous and can cause serious engine damage or personal injury.
  2. Consult your local specialist before setting your desired boost pressure, setting boost beyond your engines capability may result in engine damage.
  3. Use only high-quality fittings ensuring maximum sealing reliability. Optional Turbosmart Fitting kit available.

Recommendations

  1. Allow for adequate cool airflow around the diaphragm housing
  2. DO NOT Mount the wastegate so that the top diaphragm housing is less than 100mm from a heat source
  3. Turbosmart recommends that your wastegate is fitted by an appropriately qualified technician.
  4. Turbosmart recommends that the engines Air/Fuel ratio is checked while setting the desired boost pressure, as any increase in boost pressure can cause the engine to run “LEAN”, resulting in possible engine damage.
  5. Turbosmart recommends that boost pressure is set using a dynamometer and not on public roads.
  6. Turbosmart recommends that a boost gauge be permanently fitted to the vehicle.

FITTING YOUR GEN V WASTEGATE

Mounting Your New Turbosmart Gen V IWG Wastegate

Slide the actuator head through the BorgWarner mounting bracket, be sure the ball joint assembly has been removed form the actuator canister otherwise the unit cannot be assembled onto the bracket.
Once mounted on the bracket, secure nuts to hold actuator in place, be sure at this point to determine the orientation of the actuator as it can be flipped 180º on the actuator bracket to allow for fitting clearance, or aligning the actuator to your liking without need to disassemble the actuator.

CAUTION! Ensure nuts are tightened 

Install Actuator through bracket


Actuator secured onto bracket


Install the ball joint

Once the actuator has been mounted to the bracket, install the ball joint onto the main shaft out the actuator, orientation of the ball joint is not important. Use the flats machined into the ball joint to hold the ball joint in place as you tighten the nut on the main shaft to prevent unnecessary movement of the ball joint during operation.

Install Rod of Choice

Depending on the type of BorgWarner EFR turbocharger, they are available in different frame sizes, such as B1 and B2, and some are available in twin or single scroll configuration. As a result, we have provided all 3 rods that may be required for your turbocharger configuration. Simply select the rod length that allows for enough rod stick-out on the turbocharger actuator flap once installed. Generally, there is roughly ~5-10mm worth of stick-out on the wastegate clevis mount.
Select rod that will provide enough stick out on wastegate through hole mount in order to correctly tighten nuts either side of wastegate actuator flap mount.



 



Once the correct rod has been confirmed, install 1x nut onto each end of the rod, install rod through the wastegate actuator flap arm first, then slide up and screw into the ball joint until bottoms out, then tighten with backup nut firmly.




Applying Actuator Preload / Ensuring Wastegate Flap is Closed

CAUTION! This step is important
In order to ensure the actuator does not suffer any stiction/temperature creep issues or the wastegate flap does not stay slightly open, it is important to apply a small amount (1mm/0.039”) of preload to the wastegate actuator.
To correctly preload the wastegate, ensure wastegate flap is in the full closed position by holding the actuator flap as far closed as possible, wind the adjuster nut onto the back face of the actuator flap as shown below (in red) until hand tight



To apply 1mm/0.039” preload, simply turn the adjuster nut 1 full turn in the clockwise direction. 

To lock the actuator in this position, turn the locking nut by hand until finger tight, then proceed to tighten nut firmly to secure actuator in place. (6.5Nm / 4.8 ft lb)

If a regulated air source is available on-hand, apply the air pressure of the spring installed to the actuator (5, 7 or 14psi) and observe the rod, the rod should begin to move slowly and freely over the range of travel as air pressure increases. If the rod does not move at all with increasing air pressure, proceed to troubleshooting.

Start Engine and Check for Leaks

Congratulations, your Gen V wastegate is installed and ready for use. Double check all fittings, lines and mountings then proceed to start engine and check for leaks.

HOW TO CHANGE YOUR GEN V WASTEGATE SPRING

The Gen V wastegate has a variety of springs to suit different boost levels. Turbosmart provides the Gen V wastegate pre-installed with a 14psi spring. With your wastegate 3 springs will be provided, 5psi inner, 7psi middle and 14psi outer. Different spring combinations may be required to suit different boost requirements and tuning.

Remove Wastegate From Turbocharger

  1. Remove boost pressure source hose from the wastegate
  2. Remove preload from wastegate by undoing preload nuts
  3. Remove ball joint locking nut
  4. Remove rod from actuator and turbo assembly
  5. Remove ball joint assembly
  6. Remove wastegate actuator from bracket

 CAUTION! Allow engine to cool down before removing your GENV Wastegate.

Remove Top Cap

Prior to removing the Gen V wastegate cap, remove all fittings from the ports. Press down with light to medium load on the cap in a press or vice. Unscrew locking collar with the large end of the provided collar tool in an anti-clockwise direction until completely disengaged and slowly remove tension from the press or vice allowing the spring to expand, finally remove cap when the spring has stopped expanding

CAUTION! Use soft jaws to prevent cosmetic damage.

 


 

Configure wastegate with preferred spring combination of inner, middle and outer springs


Familiarise Yourself with Cap and Body Notches

Locate cap and body notches and grooves which dictate the alignment of the cap. These notches are used to locate the cap onto the body and must be aligned prior to compression of the cap onto the body

CAUTION! Ensure notches are aligned and seated home correctly prior to exerting force to tighten collar, permanent damage will occur if these are not aligned correctly.


43  


Press Cap onto Body

Using a press or vice, compress the cap onto the body ensuring the notches are remaining aligned. Once the cap has seated home onto the body, screw the collar down by hand in a clockwise direction. While still in the press or vice, Tighten the collar further with the collar tool until the collar will not turn.


CAUTION! Maintain downward pressure on cap while tightening collar or non-repairable thread damage will occur.




Reinstall fittings to the cap of the wastegate using fresh Loctite 567 thread sealant.

Reinstall Gen V Wastegate
  1. Install wastegate actuator assembly to bracket
  2. Install ball joint assembly
  3. Install ball joint lock nut
  4. Install rod to ball joint and turbocharger
  5. Apply wastegate preload
  6. Lock adjuster nuts
  7. Connect wastegate signal lines and check for leaks

If an adjustable air source is available, connect to signal ports and check for smooth free operation of wastegate, if wastegate does not move with increasing air pressure, proceed to troubleshooting.

ACHIEVING YOUR TARGET BOOST PRESSURE

There are various factors involved in achieving your target boost pressure including.

  1. The size of the spring fitted in your wastegate i.e. the boost pressure achieved by the wastegate spring only.
  2. The desired level of boost pressure and the difference between this and your wastegate spring pressure.
  3. The size of your turbocharger and wastegate and the resulting exhaust manifold backpressure in your system.

 Turbosmart recommends the ideal setup for achieving your target boost pressure is to use the Gen V Wastegate in conjunction with a Turbosmart e-Boost controller.

IMPORTANT NOTES ON SETTING THE WASTEGATE SPRING PRESSURE
A stiffer spring should only be used when necessary. The Gen V Wastegate allows for different combinations of spring pressures. All springs that are adaptable with the Gen V IWG are shown in the table below. The tuner can use combinations of up to 4 springs to achieve the following base boost pressures. To aid in the identification of these springs they are supplied colour coded. Please see the following detailed instructions on setting your Gen V IWG’s spring pressure. The springs chosen should be rated to the lowest boost level desired.

Connect the wires to your data logger accordingly. Use a high-quality connection to reduce noise and calibration fluctuation.

Ensure that the wiring is properly shielded from external heat sources.

CAUTION! To ensure longevity from the sensor, ensure adequate airflow is supplied directly to the sensor to avoid overheating or sensor failure.

Turbosmart HE sensor has an operation temperature window of -40C up to 170ºC (340ºF) junction temperature, for temperatures outside of this window the VOUT will revert to less than 2.5V

 Temperature exposure above 260ºC (500ºF) can cause permanent damage to the sensor.

NOTE! For best results, each wastegate should be calibrated to your setup.

TROUBLESHOOTING

  1. Wastegate not actuating - Confirm signal hose is plumbed to a pressure only source, confirm preload during installation
  2. Poor wastegate actuation - Ensure signal hose is not shared and is sourced as close to the compressor as possible, check seal on fittings.
  3. Poor wastegate actuation – Confirm no obstructions in actuator rod path.
  4. Boost creeping at high rpm - Wastegate flow path is poor, wastegate is too small for the application, ensure ball joint is not seized
  5. Failing the above, submit a Technical Request Form with information about your engine, oil type and photos of the installation and one our expert technicians will respond as soon as possible.
