Re: AC compressor options for SVX EG33
Matt I used a compressor from an 07 2.5, new from Subaru, and the corresponding mount bought used off ebay. The mount needs heavy mods, as the T belt on the 3.3 is way wider than the 2.5. Otherwise it would have been almost bolt-in. The issue is that the compressor has to be mounted and extended out from the block to line up with the AC pully on the crank. I had to cut the tabs off the block mounts and reposition them until the pulleys lined up, then drilled and tapped some small bolts to hold the tabs in place, then took the mount to a welder. (I don't weld.). I also had to make an adapter using a straight piece of steel on the other side to adapt to the outer tab. Also obtained some new compressor hoses which I just used for the fittings. Then used aluminum soldering to connect with the? hoses going forward (I was amazed that the alum soldering worked and has held for 5 years now.) I also converted to the behind-the-dash AC conversion and made my own hoses. For a belt, I used the late model stretchy, idlerless belt, same as the 2.5. works flawlessly. It was quite a project but well worth it and the conversion has worked flawlessly. I wish I had taken pictures at the time. I could post some pictures as it looks now.

Re: engine shuts off on steep downhills
IIRC the syncro speedometer is different than the 2wd and (also IIRC) there are different speed sensors.? I think this is written on the GoWesty sensor page a possible different reason for a cut out depending on how fast?you are on down hills.......(at least?my) Subi has a cut out.shut off at like 120mph.? My CV speed sensor?reads 20% higher because I read off the 6 CV bolts rather?than the 5 point speed ring.? I've adjusted my Torque App to compensate and Torque shows GPS/Actual and ECU speeds within?1mph at all speeds with that adjustment.? The ECU still sees the 20% higher speed but I figure if its reading 120mph I'm doing 100 actual which is fast enough....I think the highest I've ever gotten actual was 87mph downhill with the wind.....Now actual speed readings to the VW gauge speedometer, that's a totally different story :-P Andy Vanis USA and Whatsapp +1(505) 304-5306 On Thu, Jul 6, 2023 at 10:23?AM a.garibaldi <achilleas@...> wrote:

Re: engine shuts off on steep downhills
¿ªÔÆÌåÓýThank you all for the detailed answers on my problem. Looks like I am not the only one having this. I would like to give a few more details on that (some of them allready mentioned in the previous answers) #1 my
vanagon is syncro so fuel tank is on the back and i do have
the 12mm outlet like Richard mentioned below. The fuel tank
was cleaned a year ago during the? conversion (i am a new
conversion -only 3500 miles till now) ej25 2001 Legacy auto
trans Euro specs. #2 just
checked my speed sensor with the diagnose device of my
mechanic on the road and realized that the speed that sensor
is reading is aprox 50% higher than the actuall vehicle
speed,. We had 65km and the diagnose reading 100!! which is a
lot more. Not sure if speed sensor fail may cause shut off on
downhills. My speed sensor is attached on the speedometer on
the dash #3 i
always run with the check code #38 (auto trans torque sensor)?
#4 i have cleaned both IAC valve + the throttle position sensor a couple of months ago #5
engine shuts off when press the clutch to shift up but
restarts emidiatelly with the 2nd (unless there is an uphill
after the downhill ,in this case have to use the? ignition)

Re: engine shuts off on steep downhills
All,
While I brought up my fuel tank and evaporative containers being the only thing that I haven't replaced, including the engine, yet still having this problem, I find it odd that the original poster and I only see this problem when we push the clutch in.? So...in hindsight, while I had also replaced the clutch, I didn't touch any of the electronics associated with the actual pedal.? Maybe there's something there that would have triggered this problem with the original engine and with the EJ25 for both of us? -Greg |

Re: engine shuts off on steep downhills
Thats a lower rear outlet on fuel tank... sorry Richard Stratford ?

The engine will die because the computer is expecting auto trans. This will make O2 dive, but it will not effect fuel pressure. The problem needs to be identified as it happens. Replacing parts for me is stupid when you have no idea of what's going on. I have not even mentioned diagnosis with a scan tool...

Re: engine shuts off on steep downhills
Greg, I don't want you to buy a new fuel tank needlessly, but these things are nearing 40 years....and as diligent as you might be, that exit port with the metal screen tends to get clogged.? It might be accumulated dirt, it might be rust particles, most likely a combination.? What happens is fuel starvation downstream; very powerful fuel pump cavitates fuel causing bubbles, worsened by high ambient temps or high elevation.? Fuel injectors hate bubbles.....and these bubbles can potentially cause all kinds of strange performance problems.? I mean eventually you will need to replace fuel tank and crossovers and associated gaskets; why not now.

Re: engine shuts off on steep downhills
We had the same symptom with our now-deceased EG33 - engine died when unloaded and slowing to a stop. If I let the engine idle-down loaded, it usually didn't die. I always assumed it had to do with the ecu expecting the torque converter drag and not finding it.? On Wed, Jul 5, 2023, 11:27 Redder <greg.redder@...> wrote: Mark, |

Re: engine shuts off on steep downhills
I noticed that while coasting downhill in gear for more than 5-10 seconds the engine would stall when I put in the clutch. I solved this by giving the engine a little rev before disengaging the clutch to wake it up.? My take is the engine goes into gas shutoff as an emissions reduction routine while engine braking on a downhill and has a problem restarting the flow. I have an older 3.3 6 cyl. and this method solved my stalling issue. M Dietrich

Re: Random Switch
I responded using my phone and am not seeing what I wrote on the web site.
The red wire is terminal 58 "malfunction Indicator Lamp" The yellow wire is grounded best as I can tell from my wire tracer. Even with the plug disconected from ECU there was no tone from the tracer.? The illuminated switch acts like a check engine light. And yes, it is always on as I do not have a "code killer". I am going to leave the switch as is.? Thank you all.? |
