Installation Instructions : Turbo Inlet RS3 8Y

Installation Instructions : Turbo Inlet RS3 8Y: Page 1

1.

We will start with the assumption that the stock airbox has already been removed.
Remove the undertray

2. Remove the screws which hold the metal boost pipe in place. There are 2 screws as shown
here and in the next step.

4b. Remove the metal boost pipe.

3. Remove second screw.

4. Loosen the hose clamp around the rubber boost hose which isconnected to the metal tube.

5b. Remove the nuts holding the loom bracket in place and lift up to gain access.
5. Remove the vacuum tube from the actuator.

6. Remove the vacuum line from the plastic tube which is between the coil packs.

7. We can remove the inlet tube from the engine and leave the breather line in place. It just needs tobe disconnected from the tube by removing the 3 screws as circled. Then pull the breather out fromthe inlet – next step. Assembly shown outside the engine for illustration purposes. You don’t needto remove this breather line from the engine.

Installation Instructions : Turbo Inlet RS3 8Y: Page 37b. Remove the breather line from the turbo inlet. Assembly shown outside the engine
for illustration purposes.

8. Now remove the stock turbo inlet. There are 2 x T30 Torx screws holding it in place. One oneach side of the tube.

8b. Take the supplied blanking plate, 2 x M6 screws and nuts and blank off the opening on
the breather tube as shown. The blanking plate profile matches the gasket profile.
Assembly shown outside the engine for illustration purposes.

8c. Take the supplied silicon breather hose and push the end with the sharp bend onto theOEM breather tube which was blanked off in the previous step. Silicon hose should touch thesilver heat reflective material. Tighten the hose clamp onto the breather. Assembly shownoutside the engine for illustration purposes.

Stock Gasket
If Applicable

9. Take the new turbo flange with the 2 x countersunk Torx screws. If you are using the stock
turbo then you also need to use the stock gasket which may still be on the stock inlet tube.

10. Secure the flange to the turbo using the supplied screws – we recommend to also use athread lock such as Loctite 246. (Photo shown with engine out for clarity).

IMPORTANT

11. If using a hybrid turbo make sure the flange is secured
onto the turbo the right way around. It is possible to put
this onto the turbo the wrong way around see next steps.

12a. INCORRECT – the flange is not concentric withthe turbo inlet. Rotate the flange 180 degrees.

12b. CORRECT – the flange is concentric with theturbo inlet.

13. Take the small silicon coupler supplied – it has internal grooves. Notice the location of theTURBO SIDE writing.

14. Push the silicon onto the flange so that the “TURBO SIDE” writing is closest to the turbo. Thesilicon will be tight to push on but will snap into place as the bead around the flange locks into
the groove inside the silicon.

15. Take the supplied V Band clamp and position it on the middle of the silicon coupler. The
head of the bolt should be facing away from the engine block. Leave it loose.

16. Insert the inlet tube from the top by rotating it in as shown. You need to push it under theOEM breather hose and the new silicon breather hose.

17. Rotate it around the manifold heat shield. Feed it through the breather hoses as shownin next step.

.

18. Feed the tube through the breathers as shown with the new silicon breather hose looping
over the top and the OEM breather hose resting on top of the inlet tube.

Locate the ring around the tube
into the groove in the silicon

19. Push the carbon inlet into the silicon. If the hose clamp is not loose, the tube will not go
into correct position. The diagram shows the highlighted red ring around the tube outlet
which should go into the highlighted groove in the silicon.

20. Push the inlet tube firmly into the silicon and ensure is it fully in. Do not tighten the clamp
yet. (Hose clamps shown here were updated to the V Band clamp)

22. Another angle showing the silicon breather hose looping over the top.

23. Now push the open end of the silicon breather onto the breather opening of thecarbon inlet pipe. Secure with the hose clamp.

Installation Instructions : Turbo Inlet RS3 8Y: Page 7

23. The Carbon tube should be almost touching the first sensor block.

24. Ensure the Carbon tube is still fully engaged in the lower silicon coupler and tighten thehose clamp around the lower silicon. Do not over tighten this with a ratchet. It only needs tobe finger tight as the silicon provides a good seal.

25. Now tighten the small clamp around the breather silicon at the carbon tube end. Again –do not over tighten.

26. Take the supplied vacuum line and connect it to the plastic vacuum connector from step 6.

Installation Instructions : Turbo Inlet RS3 8Y: Page 8

27. Route the vacuum line as shown and behind the carbon inlet tube.

28. Route it down to the actuator and connect it.

29. Install the coil pack removed previously as well as the loom harness and plugs. Re-attach
the undertray.

31. Install the silicon coupler provided in the kit as shown and secure with the hose clamp.
