Finally got around to fitting the Unitronic turbo inlet elbow.
Thanks to Simon Sharp @TTE For the Elbow.
Fairly straight forward install......
Unitronic official instructions say it can all be done from the top, unlike I.E and Forge which require the lower cast pipe to be removed to access the inner elbow bolt.
I opted to do it all from the top.
First up remove the engine cover to expose the coil packs etc.
Then remove your intake pipe
Undo the coil pack connections to number 1 & 2
Then unclip the cam solenoids on 1 & 2 by pulling back on the red lock tabs then pressing down the black tab.
Undo the cam sensor
Undo the 3 nuts and move the coil wiring bar out of the way.
Then remove coil packs 1&2
Next turn your attention to the boost vacuum line.
Undo the support bracket on the side of the oem elbow, a Torx 30 bolt
Pull the vacuum line off the actuator and at the point near number 2 coil pack where it connects to the silicone line.
Next undo the Actuator off it’s mounting point and pivot arm, 2 x 10 mm nuts and a circlip on the wastegate arm
Then let the actuator go through the mounting hole so it’s out of your way
Next you’ll need to undo the 2 off Torx bolts that hold the oem elbow in place.
The inside one is a tricky one to remove but with patience it can be done, you’ve just got to get a ‘feel’ for where it exactly is and how to get the ratchet/Torx bit onto it, I found 2 hands for locating the bit easier, once you are in the bolt head it’s just a matter of loosening it enough to remove it by hand, carefully so you don’t drop it.
Once you have removed it then you can undo the easier outer one that you can actually see.
I’ve arrowed the one you can’t see, it’s directly opposite the circled top one.
Once you’ve undone those 2 Torx bolts then you need to undo the breather pipe from the engine PCV system.
3 Torx screws to be removed here
Now you can withdraw the old elbow
Next you’ll need to remove the breather pipe from the old elbow.
It’s locked into place with a security fastener
Use a Dremel with a grinding disc to cut a groove into the head and remove with a flat blade screwdriver.
Once the bolt is removed pull out the breather pipe and insert into the unitronic pipe, using the Allen bolt supplied to secure.
Transfer the flange seal ring from the old pipe to the Unitronic pipe.
A shot here of the area you are putting the new elbow into.
The above gives you an idea of exactly where that inner Torx bolt needs to go.
Take the Unitronic elbow and insert carefully into the turbo opening, keeping an eye on the seal (don’t let it fall off).
Once it’s in place you can insert a Torx bolt to hold it in place, just do it up by hand for now, next insert the rear Torx bolt, I started mine by hand carefully and screwed it in as far as I could by hand before finishing with the ratchet.
Then tighten the one you can see, ensuring the flanges are seating together squarely.
Refit the actuator and reconnect the wastegate rod with the clip.
Refit the actuator vacuum line, I connected it to the actuator 1st and to the connection near the coil 2nd ensuring it was seated correctly around the new elbow then tightened up the bracket bolt.
Reconnect the breather pipe to the PCV system making sure the pipe sits in its place at the back under coils 1&2
Once done it’s just a matter of inserting the coil packs you removed earlier, bolting them down, refitting the coil wiring bar bolting that down, then reconnect the coils/Cam solenoids/cam sensor.
You’ll then have your new elbow ready to put your hard pipe back into.
Hard pipe fitted.
