A more free flowing exhaust can go either way. It can improve the engine's breathing, which should improve efficiency, but it'll also improve power, and if you're on the go pedal more....your mileage will be less. As for the BOV, don't get one. Subaru uses MAF sensors, so if you blow off air that is already metered, the engine is actually seeing less then it metered, and your a/f ratios will be rich. The stock system uses a bypass valve, which dumps the air back into the inlet side of the compressor. This also aids in keeping the compressor spooled during shifts.

As I mentioned, the atmospheric pressure sensor is located in the ECU, and the TCU reads it from there. Check out these scans of the TCU i/o http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TCU_I-O_page1.jpg http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TCU_I-O_page2.jpg This manual has a wiring diagram that shows what I'm talking about on page 322 http://www.main.experiencetherave.com:8080/subaru_manual_scans/1992_FSM_(Engine_%26_Electrical)/ Check the wiring between the ECU & TCU. If it's fine, then that could indicate the atmospheric pressure sensor in the ECU is bad. Or the TCU is acting up. You should be able to find used ECU's or TCU's for a reasonable price in the marketplace.

The valve body is inside the transmission right above the transmission oil pan. It has passageways that channel fluid to the different solenoids and makes everything work.

Regarding the locking doors when you open the door. Read this http://www.geocities.com/hobiegary/locks.html It may or may not solve all your issues. It sounds like you have some additional problems.

It is on the valve body. The transmission pan must be removed to get at them. I don't recall if the duty b solenoid is in the upper or lower side of the valve body. If it's on the lower side, it can be removed without dropping the valve body. Otherwise the valve body must be removed.

In addition to the cable not working properly, it sounds like the control unit is not working either. This thread over the legacy central bbs goes into detail as to why that happens and what the fix is. http://bbs.legacycentral.org/viewtopic.php?t=1142

Was the power light blinking at start up, or do you have a constantly lit power light? Can you please elaborate what you mean by the transmission not going into AWD. The atmospheric pressure sensor is located inside the ECU. There is a wire that allows the TCU to read the atmospheric pressure sensor from the ECU. Here is a pic of the ECU & TCU location. http://www.main.experiencetherave.com:8080/subaru/images/ecuhide.jpg

What year & model vehicle do you have? Removing the gauge cluster isn't overly fun. An easy way to test whether the manual mode works is to leave the car in D, from a complete stop, floor it, so the car accelerates to redline, the transmission will shift. Make note of the speed when the transmission shifts from 1st to 2nd. Now repeat the test, except with the gear selector in 3 & 2, and with the manual button depressed. The acceleration should not be as good, and the vehicle speed at which the transmission shifts from 2nd to 3rd will be much higher then the 1st to 2nd shift. For example, my 90 FWD AT legacy shifted at 40 mph from 1st to 2nd, 80 mph from 2nd to 3rd, etc.

I'd suggest posting in the WTB marketplace if no one knows the size.

Just use zip ties.

Pretty much any of the newer EJ motors will physically bolt into the forester

I would probably say no they're not going to be swapable.

It's possible, but not likely a tranny flush will do anything.

What have you done for engine management? Are you using the stock ECU? You mentioned it being a 2 liter. Is this a JDM engine? The US models only came in 2.2 liter. Please provide more info on the wiring and control setup, as that is likely the issue.

The stream should be constant. It sounds like the compressor is shutting off, or something plugged (which is less likely IMO)

Your comment about the FWD fuse. The operation sounds normal. With the fuse inserted you only have FWD. So the Duty C solenoid is working. The stalling on the highway....I had similar issues, which turned out to be the MAF sensor. It did not leave a code. Only one of the last times did it leave a code.

You should have struts.

Glad you got it working. Yeah, being without AC in texas is just not a good idea. Mine was out last summer. It died while I was up in Austin. Driving back to Houston was no fun!

I dug up some info here. The fuel efficiency "island" or (3d type graph) as it's called is typically determined from test data...at least that's to my knowledge. The two axis are BMEP (Brake Mean Effective Pressure) & Engine RPM. The island or z axis is BSFC (Brake Specific Fuel Consumption) Here are two pictures showing the graph http://www.main.experiencetherave.com:8080/techinfo/auto/bsfc_island1.jpg http://www.main.experiencetherave.com:8080/techinfo/auto/bsfc_island2.jpg I took those graphs from this document http://www.cleancarcampaign.org/pdfs/MPG2K.PDF Back to the torque comment. BMEP is pretty much a direct relationship to engine torque. BMEP = 150.8 x TORQUE (lb-ft) / DISPLACEMENT (ci) Got that from here http://www.epi-eng.com/ET-BMEP.htm So, with moving the equation around, and solving for torque, you can input the BMEP values from the two graphs, and have the graph in values of engine torque. What this is more or less saying is that IF you wanted to map your engine on a dyno to find out where your max torque spots are, those would probably be your most fuel efficient spots to run your engine. This of course is not taking into account wind resistance/drag, rolling resistance, etc. Josh

Sorry Gary! I haven't done it more then that time have I??

Do you have your owner's manual? I think it is in there.

It definitely sounds like a MAF related issue. I had similar issues with my legacy. As for the wiring or the MAF sensor, you can try testing the wiring, but with intermittant problems, it's a little more difficult to get an accurate test. Do you know anyone that has a similar car or another subaru of the same year that you could maybe swap the MAF sensor to test? Other option would be to try and find a used one. As you found out, replacing the MAF sensors with new ones is expensive.

You can see the dowl pins in this pic http://www.main.experiencetherave.com:8080/subaru/images/ej22t/28/DCP_5299.JPG If my understanding is correct those would just be bolt holes....but maybe I'm way off, since I mainly deal with the older gen legacies. If you can find a pic of the back of a new engine, we could compare the two.

I don't see why you can't do this. I believe some of the forestor guys have done this. Which box are you wanting to take it out of?
