Boostin1657615274 Posted August 10, 2010 Share Posted August 10, 2010 (edited) http://legacygt.com/forums/attachment.php?attachmentid=88538&stc=1&d=1281363875 Feel free to speak up if I didn't color something right. Original credit goes to Subaru. This is for the fuel and emissions systems. The boost control, crankcase breathers, and air bypass valve (BOV) are not covered in this diagram. Subaru doesn't seem to have supplied a "complete" vacuum routing diagram like a lot of other manufacturers do. You should see a 1993 Rx-7 vacuum routing diagram... 76 hoses. Here is a colored diagram to show turbo system routing: http://legacygt.com/forums/attachment.php?attachmentid=88558&stc=1&d=1281402455 Finally, here is a diagram of the crankcase ventilation. The diagram was left uncolored so as not to obscure the arrows which show how the air flows. http://legacygt.com/forums/attachment.php?attachmentid=88559&stc=1&d=1281402455 Also, for an ECU pinout for 2005-2006 see this thread: http://legacygt.com/forums/showthread.php/click-here-2005-legacy-gt-ecu-pinout-126185.html?t=126185 Edited August 10, 2010 by Boostin On the search for a new DD...

underpowerd Posted August 12, 2010 Share Posted August 12, 2010 good to have these pics at hand; just one caveat leaps out at me: there's only pressurized fuel in quite a few of the lines in pic 1, the thread title might mislead a greenhorn otherwise -- never can be too careful dealing with that stuff Link to comment Share on other sites More sharing options...
Cincy05LGT Posted August 12, 2010 Share Posted August 12, 2010 This absolutely pales in comparison to the vacuum diagram for my 1983 Mazda Rx-7. I stripped the carb and engine of all emissions controls and it stall has more vacuum lines than our Legacies. Thank god for modern cars! Link to comment Share on other sites More sharing options...

I hear its one of the most important things to in the vaccum lines. I think I was just looking at that the other day when the car was apart for a clutch. Maybe it's colored green in the first diagram? The 3-way joint near the purge valve? Edited September 15, 2010 by Boostin On the search for a new DD...

ERLoft Posted May 18, 2014 Share Posted May 18, 2014 Is there one of these diagrams for the 2007 version anywhere? I know the 07 cars don't have the blue tee, so my real question is where does the vacuum line go to? 2013 █S4 - Glacier White - DSG - B&O - Tech Package - Sports Diff - Napa - RS4 Grille - Stasis Exhaust - APR Intake - KW Variant 1 - Stern Control Arms - CR-15 - Stasis RSB - Moog Endlinks - PC Hyper Black Peelers - Deval Front Lip - ECS Rear Diffuser - Carbon Imports Ducktail - ECS Mirror Caps - Relak Paddle Extensions - Autostyle Floor Mats - LED Interior - V1 - Blackvue DR900s - [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...

ERLoft Posted May 19, 2014 Share Posted May 19, 2014 Thanks MC! I'd actually figured it out anyways. One vacuum leak fixed. Not sure if my stalling issue is vacuum related or not.

Hoojammyflip Posted January 2, 2015 Share Posted January 2, 2015 Thanks for all the info and diagrams... How big a job is it to get the inlet manifold off? Link to comment Share on other sites More sharing options...
Andyjo Posted January 2, 2015 Share Posted January 2, 2015 Turbo inlet, or throttle body inlet? Throttle body inlet is easy, yank the intercooler off and it's right there. Turbo inlet has a lot more plumbing attached to it, and is easy to rip, and takes removing quite a bit more.... Link to comment Share on other sites More sharing options...
