Wastegate setup

From our humble beginnings to establishing ourselves as a global brand. Turbosmart is well on track to lead the future in turbo technology. Our engineers, build and track test all products in-house. For this reason, our products are designed to be used on both track and street applications. September 19, Products. Internal Wastegate Setup.

Allow the engine to cool down before installing your boost controller. Locate the pressure source port and the wastegate actuator port on the turbocharger assembly. Remove the factory boost control solenoid if fitted from the boost pressure supply port while leaving the solenoid connected to the ECU. Install your boost controller in the wastegate pressure line with the wastegate arrow pointing towards the wastegate actuator. If your wastegate actuator has additional ports, these will need to be blocked.

Secure all silicone hose ends with hose clamps. Mount your boost controller bracket onto the vehicle, then attach the boost controller onto the bracket with the supplied screws. Make sure the boost dial is turned completely anti-clockwise before making adjustments.

External Wastegate Setup. Locate the bottom port on the external wastegate and the pressure source port. Install the Boost Tee in the wastegate pressure line with the wastegate arrow pointing towards the bottom port on the wastegate. Parallel Twin-turbo Setup. Locate the wastegate actuator ports on both turbochargers and a pressure source port. Remove the factory boost control solenoid if fitted from the boost pressure supply line.

Install your boost controller in the wastegate pressure line with the wastegate arrow pointing towards the wastegate actuators. Be sure to keep the hoses joining the wastegate actuators at equal lengths. Have more Questions about Turbosmart Products? Download our Latest Catalogue Here. Contact Us.

Be sure to break the small 6X1. Thread a bolt into the hole and place over a vice as shown and hit the top of the bolt with a hammer.

The nut has been broken free - remove this piece and discard it. Place the bracket into a vice as shown and using a hacksaw or portable bandsaw, cut the bracket along the line. Once you have done this, place the actuator plate in the vice and cut the remaining piece of the bracket free.

Testfit the piece and ensure that your angle is proper. Remove the bracket from the turbo and remove the actuator from the bracket. Place the bracket into a vice and tack-weld the plate into place. Put the actuator onto the bracket and test fit once more after the tack-welding.

Using a marker, place a position indicator for the location of the compressor housing bolt. Place the bracket into position, noting the location of the actuator rod to the wastegate shaft, and draw a locating mark on the bracket.

On these turbochargers I measure a distance of 0. Attach the bracket to the compressor housing. Install the actuator and check for fitment. If everything fits properly, apply your final weld to your bracket. Attach your bracket to the housing and apply a small tack weld between the bracket and the housing retainer plate.

This will ensure that there is no rocking of the bracket since we are only able to use one mounting hole. Final install your actuator using the self-locking nuts provided in the kit. Be sure to point the actuator hose nipple in the orientation shown. Install the actuator rod locknut and collar and place the wastegate arm into position. Adjust the rod length until you have a degree angle between the actuator rod and the wastegate arm. Using a circular motion with your MIG welder, fill in the hole to re-join the wastagate shaft to the arm.

One thing to note while doing this - be sure to push the wastegate upwards and hold it shut before you make the weld. If you dont do this, the wastegate will likely be lower than it should and not fully closed - this will defeat the purpose of repositioning the arm, so be sure of this before you lay your weld in.

At this point, you have completed the first half of the setup of the driver's turbo actuator. Passenger Side In this picture I have setup the actuator and arm in the position that I ultimately want to install it in. This position will give us the best possible fitment of the actuator onto the turbo for mounting onto the engine. The passenger turbocharger is a difficult turbo to install the actuator onto due to the limited space on that side of the engine. The actuator is between the cylinder block and the compressor housing, and in many cases, the engine mount bracket gets in the way.

The location I am putting this actuator into works on my engine as it has for many other turbos I have setup, but you will need to verify that everything fits reasonably along the way. To start, remove the two small 6X1. These WILL get in the way if not removed. Trial fitment of the bracket. The shape of this bracket puts the actuator mounting plate too far away from the compressor housing and it will interfere with the cylinder block.

Mark the bracket with a line tangent to the periphery of the compressor housing as shown: Cut the bracket and mount as shown. Cut the remaining edge from the top half of the bracket flush with the leg of the actuator plate. Spot-weld the bracket into place and check for fitment on the engine.

Once you have massaged the parts for proper fitment, apply the final weld to your bracket. Install your bracket and actuator onto the turbo. Install your locking nut, collar and wastegate arm, taking care to get that degree angle. Final weld your wastegate arm, again taking care to position the wastegate closed and in the upper-most position prior to welding.

Be sure to weld the bracket to the compressor retaining plate by filling the second hole in the bracket's mount. At this point, you will have two turbochargers ready for actuator pressure calibration and balancing.
