The three stage conversion was not very difficult, you just need the right tools. I recommend that you have torx bits. All in all the conversion, including installing the new afe intake and doing the aa tune, it took me about 6 to 7 hours. Just be patient and take you time, you dont want to mess anything up.
obviously the intake and the tune are not needed to do the conversion, but to take full advantage of the new intake with the disa's you will need a tune.
here is a list of parts you will need. Search around for everything, you should be able to get everything for around 300-350.
11617559523 Intake Manifold
11617579114 Adjustor Unit
11617560538 Adjustor Unit 2
11617547242 Gasket set
11617535850 x2 Screw 50x35
11617535849 x4 Screw 50x20
11617535851 x1 Screw 50x66
some other lists say you need 5 of the 50X20 screws so thats what i had bought but i only used 4, i could not find anywhere that the 5th screw would go so i have an extra one now lol
These are the two wires that will plug into the DISA Adjusters on the new intake manifold. The longer one of the two is that one that will wrap around the manifold and plug into the adjuster facing the engine block.
First things first you need to remove the Air Box
and take the two nuts off to looses the power steering fluid reservoir.
Once you get the air box out, move the steering fluid reservoir over to the side and it should look somewhat like this.
Now remove all of the plastic pieces from around the engine. Just be careful not to break any of the plastic clips, everything came off pretty easily and was pretty self explanatory.
The engine bay should look somewhat like this now.
Now i didnt get any pictures of it because i got so caught up in working that i kind of forgot, but you need to remove the throttle body from the manifold, there are 4 10mm bolts holding it on. also remove the vacuum hose that is right behing the throttle body on the air intake manifold. Just squeeze the connection and it pulls right out.
Now you need to disconnect a few wire before you take off the manifold.
Once you get those disconnected, just go around the manifold and look for any wires that many still be attached.
Now you can take off the bolts and nuts that are holding the manifold onto the engine. lift up on the manifold so you can reach behind and disconnect the two hoses and one wire that you will see. Also there is a bracket that is connect to the manifold, under where the throttle body was, you need to use a torx bit to remove the two screws that are holding it to the manifold. Once you are sure that you have everything disconnected from the manifold you can slowly pull it out making sure you did not forget to disconnect anything.
Now that you have out the manifold, move any brackets that may still be attached to it, to the new manifold. Also be sure to put the new gaskets one the new manifold and screw in the DISA Adjusters.
Old Vs. New
Now just revers all the steps and be sure to plug in the DISA Adjusters, double check that you are plugging everything back in.
Once you are done it should look like this
Let me know if anyone has any questions and i will try to answer it.
