These instructions are based around a stock Evo 8 MR, but should translate well to other models.

Step 1 - Remove the factory air scoop by undoing the 2 panel fasteners that hold it in place on the radiator support. Remove the cover of the factory airbox and the air filter. Loosen the 2 bolts that hold the airbox in place.



Step 2 - Remove the factory DV by loosening the 2 10 mm clamps that hold it in place. You will also disconnect the vacuum line to the factory DV.

Step 3 - Loosen up the turbo inlet hose connection to the factory airbox and disconnect from the factory airbox. Whenever possible, you may want to re-orient the factory clamps to make it easier for yourself to access them in the future, or when putting everything back together.



Step 4 - Loosen the clamp that holds the turbo inlet hose to the compressor. You will then rotate the turbo inlet hose towards the radiator. In some installations the clamp's bolt is inaccessible. You can simply grab the turbo inlet hose and rotate it by hand without loosening the clamp.



Step 5 - Remove the upper intercooler pipe. Loosen the clamp to the DV inlet hose and rotate hose orientation towards the radiator. You will want to reposition clamps so that they are easier to access when tightening everything back together.



Step 6 - Once you have re-clocked the piping to orient the DV's location closer to the radiator, reassemble the turbo inlet pipe with the airbox. Also re-install the upper intercooler pipe. Make sure to allow the piping to retain their newly clocked orientation.

Step 7 - Use the factory clamps and install the Synchronic DV in the same orientation as the OE DV.





Step 8 - Re-install the factory airbox. Re-install the factory air-filter and the factory airbox cover.



Step 9 - Follow the vacuum routing instructions from your Synchronic DV installation manual. Use the vacuum line that used to connect to the factory DV to tee into Port A&B on the back of the Synchronic DV.



Step 10 - Connect the boost-only source to Port C of the Synchronic DV. Boost-only can be sourced, by tee'ng the signal line from the turbo's compressor to the wastegate actuator.



Step 11 - Re-install the factory airscoop and carefully routing the vacuum lines through the split line valley in the airscoop.

 

okieeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

 

so this doess what, whats wrong with the way it was

 

If you don't reclock the turbo inlet pipe and the DV inlet hose, the Synchronic DV can't clear the upper radiator hose, or will rub on it. You'd be amazed by how many people can't figure out to just rotate hoses. They'll just look at it and say that it doesn't clear.

 

what goes on port c

 

Boost-only source coming from the compressor housing or intercooler pipe. Tee the line that is coming off of your compressor housing.

Here's the updated instructions, page 6:

Step 10 - Connect the boost-only source to Port C of the Synchronic DV. Boost-only can be sourced, by tee'ng the signal line from the turbo's compressor to the wastegate actuator.
this step is kicking my butt, i have a line going from my wga to my avc-r solenoid, i tee'd this off is this right, because wga doesn't seem to be working properly with this configuration

 

You need to tee before the WGA solenoid.

So, put a tee between the compressor and AVC-R solenoid.
