MilwaukeeMike Posted September 20, 2011 Share Posted September 20, 2011 2 Issues 1 (may not be an issue) KStech has block off plates for 07+ LGTs - mine is an 05? 2 Gaskets are on backorder - Is there another place to look. I poked around a little on google, ebay, and nasioc? Link to comment Share on other sites More sharing options...
B-BGTLimited Posted September 20, 2011 Share Posted September 20, 2011 (edited) That might be because an 05 has the up pipe cat and not the air pump system... its an 07+ substitute for that up pipe cat. Hence the title of this thread "2007-2009" Edited September 20, 2011 by B-BGTLimited Link to comment Share on other sites More sharing options...
m sprank Posted September 21, 2011 Author Share Posted September 21, 2011 Your motor is 07-09, yes? Thats why you want them. There is no different motor designation for the air pump. It is referred to by model year. If gaskets are on back order from Subaru, good luck. I might have 1 in my tool box, but not all of them. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted September 21, 2011 Share Posted September 21, 2011 I missed that post... But yeah if you have an 07 motor why would you be looking for an 05 setup for plates? You need to reference parts for whatever your engine came from. Its the same with my Beretta... Thats and 05 engine in a 96 car... with a 96 trans and 04 heads, and 00 brakes and yeah you get my point... only the shell is a 96. Also why not just re-use the gaskets that come off the pipes? Being they are MLS type gaskets you will probably be able to re-use them with no issues. Link to comment Share on other sites More sharing options...
shtbxr22 Posted September 21, 2011 Share Posted September 21, 2011 They are single layer metal, but you're right about reuse. There shouldn't be an issue. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted September 21, 2011 Share Posted September 21, 2011 I looked at them to quick, I thought they were at least two layers. Link to comment Share on other sites More sharing options...

BAC5.2 Posted September 21, 2011 Share Posted September 21, 2011 I've thought about deleting the air pump, simply to make maintenance a little easier.

a.lim Posted November 30, 2011 Share Posted November 30, 2011 2 questions for ya.. I have the air pump delete done, but the passenger side solenoid is fully intact. So as long as I cut the top portion off and remove all the magnetic wiring off the black piece I can plug it back in and it would run fine? Can I pass smog with this delete?

shtbxr22 Posted November 30, 2011 Share Posted November 30, 2011 If it was NH, I would say yes. I would think if all your monitors are ready, and no CEL is present you should be ok. I would talk to a CA state inspector..... Link to comment Share on other sites More sharing options...

Yes, the top part (black) contains the required atmospheric sensor. Keep that and you can delete the codes for CEL's. The car has everything it needs to run properly. As for smog. A good tech might notice the missing pump. But I doubt it. If that is the only mod done to the car (and it is tuned) it should pass smog. But with any mods, you are generally looking for a "friendly" shop to begin with. Link to comment Share on other sites More sharing options...
Zero1 Posted December 6, 2011 Share Posted December 6, 2011 The only time a sniffer would have any chance of detecting this would be during cold warm up period on the car so if you're driving to a place to get it checked, you're good as gold. If you have to leave it there overnight and they check at cold start up, you might be screwed lol. Same goes with the TGV's. The two systems are only used to help warm the motor faster at start up without just dumping lots of fuel in so there isn't a ton of unburned hydrocarbons coming out the exhaust.

B-BGTLimited Posted December 6, 2011 Share Posted December 6, 2011 I don't even think they would be allowed to test it during a startup procedure, that's just completely unfair since the cat itsn't even fired off yet. Link to comment Share on other sites More sharing options...

I believe one of the requirements for sniffer testing is that the vehicle is at operating temperature.

m sprank Posted December 6, 2011 Author Share Posted December 6, 2011 In Cali, it is an idle/2500 rpm test. Car does not have to be at "operating temp", afaik but it usually is. Most techs start it up and then do the visual as it warms up. Bring it in good and warm, after a nice drive. Should not be any issues. Air pump is only in operation for about 30 seconds at start up. No one is going to test at start up. Link to comment Share on other sites More sharing options...

m sprank Posted December 9, 2011 Author Share Posted December 9, 2011 If car is completely stock and you have the pump delete, opensource can be used to turn off the CEL's associated with the missing pump. If car is good and warm when they smog test, it will pass. Air pump unit is out of operation and bypassed after about first 30 seconds of the engine running, even when it is installed. It is only there to redirect hot exhaust gas and more quickly heat the cats to get them to operating temp faster. Link to comment Share on other sites More sharing options...
shtbxr22 Posted December 10, 2011 Share Posted December 10, 2011 I disagree with the air pump reason. I have been taught that since subaru eliminated the cat in the uppipe to keep them from lodging in the turbo, they needed a way to "clean" up cold start emissions, hence the fresh air added to the exhaust via air pump for the short time after cold start up.

m sprank Posted December 10, 2011 Author Share Posted December 10, 2011 Been a long time since I even looked at an air pump. Lol. But I do not recall any outside air inlet. I am also confused as to how a small amount of "fresh" air would dilute the exhaust gasses enough to satisfy California Air Resource Board. But, anything is possible. I was told by a Subaru master technician that the sytem redirects hot air into to assist in heating the cats to operating temp faster. Hence cleaning up cold start emissions. Regardless, the engine bay is much easier to navigate without that POS in the way. Lol. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted December 12, 2011 Share Posted December 12, 2011 (edited) The Air pump itself has an inlet where it pulls in fresh outside air to pump into the exhaust ports on the head. Our systems are used only to bring the exhaust gas temps higher right at start up to activate the cat quicker and lessen the time that it's not working efficiently. Secondary air injection From Wikipedia, the free encyclopedia Jump to: navigation, search Secondary air injection (commonly known as air injection, or colloquially smog pump) is a vehicle emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream to allow for a fuller combustion of exhaust gases. Contents [hide] 1 Development2 Methods of implementation2.1 Pumped air injection2.2 Aspirated air injection [*]3 See also [*]4 External links [edit] Development The mechanism by which exhaust emissions are controlled depends on the method of injection and the point at which air enters the exhaust system, and has varied during the course of the development of the technology. The first systems injected air very close to the engine, either in the cylinder head's exhaust ports or in the exhaust manifold. These systems provided oxygen to oxidize (burn) unburned and partially-burned fuel in the exhaust before its ejection from the tailpipe. There was significant unburned and partially-burned fuel in the exhaust of 1960s and early 1970s vehicles, and so secondary air injection significantly reduced tailpipe emissions. However, the extra heat of recombustion, particularly with an excessively rich exhaust caused by misfiring or a maladjusted carburetor, tended to damage exhaust valves and could even be seen to cause the exhaust manifold to incandesce. As emission control strategies grew more sophisticated and effective, the amount of unburned and partially-burned fuel in the exhaust stream shrank, and particularly when the catalytic converter was introduced, the function of secondary air injection shifted. Rather than being a primary emission control device, the secondary air injection system was adapted to support the efficient function of the catalytic converter. The original air injection point became known as the upstream injection point. When the engine is cold, air injected at this point cleans up the extra-rich exhaust and raises the temperature of the exhaust so as to bring the catalytic converter to operating temperature quickly. Once the engine is warm, air is injected to the downstream location — the catalytic converter itself — to assist with catalysis of unburned hydrocarbons and carbon monoxide. [edit] Methods of implementation [edit] Pumped air injection Pumped air injection systems use a vane pump turned by the engine via a belt. The pump's air intake is centrifugally filtered by a rotating screen to exclude dirt particles large enough to damage the system. Air is delivered under pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components. Carbureted engines' exhaust raw fuel content tends to spike when the driver suddenly releases the throttle. To prevent the startling and potentially damaging effects of the explosive combustion of this raw fuel, a diverter valve is used. This valve senses the sharp increase in intake manifold vacuum resulting from the sudden closure of the throttle, and diverts the air pump's outlet to atmosphere. Usually this diverted air is routed to the engine air cleaner or to a separate silencer to muffle objectionable pump noise. [edit] Aspirated air injection Air injection can also be achieved by taking advantage of the negative pressure pulses in the exhaust system at engine idle. A sensitive reed valve assembly called the aspirator valve is placed in the air injection plumbing, which draws its air directly from the clean side of the air filter. During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the catalytic converter. This system, marketed as Pulse Air, was used by American Motors, Chrysler, and other manufacturers beginning in the 1970s. The aspirator provided advantages in cost, weight, packaging, and simplicity compared to the pump, but the aspirator functions only at idle and so admits significantly less air within a significantly narrower range of engine speeds compared to a pump. This system is still used on modern motorcycle engines, e.g. the Yamaha AIS (Air Injection System).

m sprank Posted December 12, 2011 Author Share Posted December 12, 2011 I have not. Looked at an air pump system on Saturday. Pump housing is the inlet. It is moving "fresh" air into the heads. It looked like one heck of a job to do it with the turbo in and manifold on. Link to comment Share on other sites More sharing options...
fahr_side Posted January 2, 2012 Share Posted January 2, 2012 Is anyone else seeing an uptick in these pumps or solenoid valves failing? I've seen a half dozen stuck solenoids on '06 WRX, '06/'07 FXT models lately, and many times the air pump dies shortly afterward from rust. I'm assuming the valve being stuck open allows exhaust gas laden with condensation to blow back into the pump. 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.
