So I am new to the WRX ownership and noticed to day that something was not right. I have a 06 WRX and it has a STI top mount IC swap but I looked and the bov recirculating hoes was very very kinked right out of the bov. So I decided to pull it out. Just the hoes that is. Then get something longer to replace it with. Turns out there is no room to speak of under the TB so I was just baffled on how you would even replace something like that. There is no space at all big enough to run that hoes through. Ripping the old one out was a chore in its self and it was even crushed pretty bad at that tight spot. So I ghetto rigged something with some 1" elbows and recirc tubing to reroute it and its still ridiculous. I am kind of pissed LOL its very frustrating. Is this common? Because I have been researching the swap and everything I can to come up with a similar story and its not working. So my question is, is there a proper way to do this or something that the previous owner must have done incorrectly? Any input helps I just am not happy with my ghetto alternative. There has to be a better way.

Oh! There is allot of crazy, and what seems unnecessary vacuum lines running certain places and to the intercooler making that area for the recirc tubing more cramped than it already is. I wonder if these can be nixed because they are taking up recirc tubing prime real-estate.

Thanks.

"Hoes" are nasty women. "Hose" is a hose:lol:

It sounds to me like you bought it from someone who had an aftermarket blowoff valve. That person (probably in high school) took it off before selling the car to you and did a poor job of putting everything back.

I'd look up the STI intercooler swap on NABISCO. Also, while on there, look up how to install an aftermarket blowoff valve. That may give you some clues as to what was cut/removed/messed with. There will probably be pics of how it should look. You can also find someone in the area with a stock WRX and compare. You may also try opposedforces.com. You can look up your engine, and hopefully there will be some kind of vacuum diagram or something.

Hey, thanks. Yeah I am a horrible speller and use the wrong form of the same word all the time its dumb. ha fml.

Yeah thanks for the sites I'll check them out. Also yeah I thought about looking at a stock WRX to see if it gives me a clue that's probably my best bet.

It may be, but with the STI intercooler, I don't know how much needs to be rerouted. That's why I suggested looking up that mod on NABISCO as well. But yeah once you know the differences, you should be able to get a good idea of what goes where. If you were in Portland, I'd let you take a look at mine.

One more question I want to make it recirculate again, but is it safe to drive with the intake part of it plugged off and it venting to the atmosphere? I know people do it and there are write ups on this like crazy just wondering what you have to say on it. It idles alright and seems to run fine for the most part. Not trying to leave it like this for very long.

Subaru set it up the way they did for a reason. Your car will run ok, but not at its best. You'll run a little rich at certain points because the computer is dumping in the amount of fuel it thinks it needs based on the amount of air it thinks is coming in. Since some of that air is going to the atmosphere instead of into the engine, the computer is dumping more fuel than it needs to. It won't be enough to foul your plugs or O2 sensor for a very, very long time, though.

Does that make sense?

It'll be fine for your drive to the dealership or Home Depot or whatever to get the things you need to fix it.

you might not even have a stock tmic, it could be some ebay hack job.

Please post some pics of the tmic and the bov and we will give better advice.

The vac lines are all necessary. Do not start ripping out lines you think you don't need. If you want less stuff under the hood I'll trade you for my legacy :rolleyes:
Turbo systems are complex, and with that comes lots of hoses, valves, and wires.

Venting to atmosphere won't hurt anything. It just wastes fuel (although....sometimes that's burned off in the form of fireballs out the exhaust between gears).


Yea, sounds like the PO did a halfassed return to stock.

there are a lot of vacuum/vent lines in the stock config, but they all have their place. It shouldn't look too crazy. A lot of these things are for the emissions system, and will not hurt how the car runs to remove, but it's not for the novice mechanic, you need to know exactly what everything does.

Thanks for all the input. I already understand everything you guys are saying to me I just need to see a stock set up. Its a legit STI intercooler no doubt about that. I guess whats happening with my recirculate tubing is just to hard to try and explain I think people are getting different ideas in there head other than whats actually going on. Thanks again though for the response. I'll get it done.

The factory hose is probably a pre-molded piece that's formed to make the bends in the right places. If a generic hose is used, then it will kink where the tight bends are. You may have to buy the right hose from the dealership, they can look it up for you and you can point at which one in the picture is the one you need.

Hey thanks yeah I guess that is worth looking in to for sure, However it seems like the one I pulled off that was kinked was a pre-bent hose. However I do have it fixed thanks to some ghetto fabulous engineering with material from Lows and radiator hose form Auto Zone. lol she runs awesome now so whatever. Ill go to a dealer and look that part up though for sure good idea! But now I'm not so rushed. I hated it venting to the atmosphere, such a huge difference in the way the car runs I don't get how anybody would rather have the blow off sound than have a smooth running vehicle.

Thanks again all good to go!

To answer why they want it to vent to atmosphere, is because so many un-informed people think they are smarter than the engineers who have spent years researching the correct way a vehicle runs.

In turn, they blow up way too many of these cars than is neccessary al while they add 200 pound speakers and make them slower than the factory makes them.

rant over
