timbo7 Posted May 23, 2012 Author Share Posted May 23, 2012 So is there a hose that is known to crack? Just asking because it's going to be very hard to try and look at every hose to find one with a crack in it. Link to comment Share on other sites More sharing options...
timbo7 Posted May 23, 2012 Author Share Posted May 23, 2012 Do you guys think its worth the extra money for the tune with the revisions if im all stock or are the ots maps okay? Link to comment Share on other sites More sharing options...
timbo7 Posted May 23, 2012 Author Share Posted May 23, 2012 Ok guys, sorry for being a pain but I think I finally found my problem. I mustve looked about 10 times and I think I found it. The pipe that goes into the turbo looks torn, like the rubber pieces from the clamp are coming thru the clamp. Ive attached a photo, kinda hard to see it though. Is this a job I can do myself or should I take it somewhere? http://i145.photobucket.com/albums/r206/bananamane/C360_2012-05-23-15-53-19.jpg http://i145.photobucket.com/albums/r206/bananamane/C360_2012-05-23-15-52-41.jpg I know the pictures are crappy sorry.

fahr_side Posted May 24, 2012 Share Posted May 24, 2012 You might confirm that is the leak site by spraying ether / engine starter at it while idling. The stock turbo inlet tube can only be installed with the manifold off. You can hack it up and pull it out without removing the manifold, but it's impossible to install a new one with the manifold in place because it's too stiff to shove in there in one piece. You can buy a soft silicone inlet like the Perrin which can be squeezed in there without removing too many other parts. It's not an easy install but taking the manifold off is by comparison a real pain in the ass. http://www.perrinperformance.com/shared/PERRIN/documents/instructions/subaru/pspint420.pdf http://legacygt.com/forums/showpost.php?p=1678628 Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

Do you have any idea how much the stock piece is? I've looked on a few OEM Subaru sites and couldn't find it. But I guess if I'm going to tackle it myself I should fork over the money for the perrin. I saw that thry changed the design of it so hopefully there is no fitment issues. Link to comment Share on other sites More sharing options...

fahr_side Posted May 24, 2012 Share Posted May 24, 2012 Think it's wOrth it to get the perrin over the stock? Depends on what you're looking to get out of this purchase. Stock is stealth and cheap, but splits easily. If you're going to swap turbos or something in the future then it will split again. It's a bitch to swap. A Perrin is sturdier, much easier to replace, but is more expensive. There is no performance advantage in aftermarket. Many other aftermarket inlet tubes fit very badly and are a total bastard to install, or come apart very easily. The inlet on my own car has a small tear in it after testing a half dozen different turbos in a month. I have it sealed up now but the next time anything in the intake is touched a new aftermarket inlet will be going on, simply because I don't want to mess with taking the manifold off until I'm ready to do other things under there like an injector swap, TGV delete and/or secondary air solenoid delete.

timbo7 Posted May 24, 2012 Author Share Posted May 24, 2012 I just got home with some engine starter, I sprayed it around the turbo inlet hose and the idle didnt change. Any idea why it didnt change? Im still pretty sure its messed up there. I took off the intercooler and took some better pictures. Im going to go ahead and order the perrin inlet hose and put that on. http://i145.photobucket.com/albums/r206/bananamane/DSC_0004.jpg http://i145.photobucket.com/albums/r206/bananamane/DSC_0003.jpg http://i145.photobucket.com/albums/r206/bananamane/DSC_0002.jpg Link to comment Share on other sites More sharing options...

fahr_side Posted May 25, 2012 Share Posted May 25, 2012 It's messed up. Someone did a terrible job of putting that clamp on. If it's not leaking now, it soon will be.

timbo7 Posted June 3, 2012 Author Share Posted June 3, 2012 Just got done doing the turbo inlet...major PITA!! Ran another log. Heres the info. My trim A was lower before when I had the paper filter in but after I fixed the inlet I put the avo in, so the log was with avo. Sorry guys, I know I shouldve listened. I just got done putting the paper filter back in and reset the ecu because I was getting a CEL cause of the PCV plug but its taken care of now so I thought ide reset it now that its all back together. Ill do another LV and log after a few more days of driving, just thought Ide try one tonight. Let me know if it looks any better.

timbo7 Posted June 7, 2012 Author Share Posted June 7, 2012 Heres my LV after driving about 75 miles or so with a regular filter. All stock now except the perrin inlet hose I just replaced. I dont understand why my trim A is still high. I made sure everything was plugged back in and no loose hoses. I even zip tied the T under the intercooler while I was in there. I plan on going stage 2 in the next few weeks ( have DP and UP waiting for gaskets ) Is there anyway that this could be caused by a bad tune from the factory?

bmx045 Posted June 7, 2012 Share Posted June 7, 2012 Eh. All are within 5% except idle. You drove 75 miles but did you idle in order to settle that trim? Clean maf? Properly seated air box? Link to comment Share on other sites More sharing options...
fahr_side Posted June 7, 2012 Share Posted June 7, 2012 Wow, you're not catching a break here. You may still have a leak. Normally all the values will be negative and within a 5% range. Is your idle rough? You might be leaking at the intake manifold gaskets as you have such a high value where vacuum is highest (idle). You could try spraying starter fluid / either around the TGV housings while idling. Think about having your injectors cleaned. Can you borrow a front O2 sensor for a test? Fix your issues before tuning. You don't push a sick athlete to go training, do you?

I didn't really just sit anywhere and let it idle just at stop lights and stuff. Most of it was highway driving. I tried cleaning maf sensor before. Will it just stop reading if it's bad or could it be going bad? Airbox is good I checked it again. When I emailed infamous a few week ago he didn't really seemed concerned because it's under 15 he said. Not saying you guys are wrong just saying.

fahr_side Posted June 7, 2012 Share Posted June 7, 2012 You will run rough after a reset, that's normal. Fuel trims jump around a lot, cam advance can differ by several degrees left/right... I mean take them out and have them cleaned professionally. Can't really diagnose a bad O2 sensor other than swap and try. I'd borrow before buying.

timbo7 Posted June 7, 2012 Author Share Posted June 7, 2012 Well I drove some more. It seems like the idle trim is getting a little lower now. Maybe I just have to keep driving it. Is there any parameter in RR that will help identify this? Ill leave everything be for a few weeks and see what happens. I plan on doing the UP and DP in about 3 weeks. I tried spraying around the manifold and idle didnt change, I sprayed a few other places and nothing happened either. LV: Link to comment Share on other sites More sharing options...
iNVAR Posted June 7, 2012 Share Posted June 7, 2012 That lv looks decently good to me but keep driving. Don't reset the Ecu or re flash. but... Fahr_side has seen a lot of cars though so if he says that trims are usually supposed to be slightly negative, then he's most likely right.
