    Colin: hopefully its something simple. What a frustrating experience.

  • I can't believe that a better solution does not exist to boost horsepower/performance for the 2.5L forester engine. I bet the engine is "tuned down" for the US market and could be adjusted by modifying the electronics. Any ideas?
  • paisanpaisan Posts: 21,181
    In today's car world the manufacturers pretty much tune them as high as possible to squeeze out all the hp they can. For instance the S2000 when tuned by the performance arm of Honda can only get 15hp more than stock.

    You can tweak it some. Here are rough prices and claimed power gains (my estimates) from a few mods:

    $40 K&N Filter, 3hp
    $150 complete intake kit, 5hp
    $180 UR Underdrive Pulley, 5hp
    $400 various cat-back exhausts, 5-15hp
    $200? high-flow catalytic converter, 5hp
    $400 headers, 5-10hp

    Beyond that, you get into cams and forced induction, which gets very involved and pricey.

    You can probably combine a couple of these to get another 10-15 horsepower out of it, but beyond that it's not very cost effective.

    I've ridden in two turbocharged 2.5l cars (Imprezas), and they are brilliantly fast. It's amazing what they can do for $3-5 grand. Basically you get what you pay for. Those two cars would pin you in your seat, easily quicker than a stock WRX.

  • Hi, I'm new to this board.

    I own 4 subarus all of which run Bosch platinum plugs.

    I recently had ONE service manager tell me that the Platinum plugs in the 1996 2.2 liter Subaru have to go, because the 2.2 liter enginge was "not designed" for platinum plugs.

    I told him I have these in all my cars, they all run fine, that I've been working o ncars for 40 years, and so long as it was the correct temperature range plug, and fit in the car, it did not matter whether the plug was made out of platinum or irridium, or steel.

    Anybody ever hear of this from any other dealer? I contacted subaru with the question and am awaiting their response - if any.

    Personally I think this is one service manager's [non-permissible content removed]. but am open to researching even though his comments make no sense to me.

    PS. enging runs fine, no missess, revs up, good mileage, what brought this to bear is a "check engine" light and bad sensor in the car which I am replacing.

    please give me your input

    thanks

    We have the same problem in the Troopers. But these are on ODBII Direct fire cars, it seems that they have higher or lower resistance and this causes the ODBII computer to go haywire when there is not the proper resistance or something, and they get a CEL come on. Unless it was the other whacky plugs doing it splitfire or something like that. I'll have to check it out and get back to you.

    believe it, goldenrover. all those things juice mentioned will largely only help high RPM as well.

    you're incorrect about the state of tune. the EJ25 SOHC is tuned for lots of midrange and part-throttle torque. foreign markets that get this engine get it just exactly as we do.

    if there were something very easy and inexpensive to do to boost power, subaru would be doing it to the production engines.

    -Colin
  • paisanpaisan Posts: 21,181
    a lot of those options juice mentioned may decrease your power in the low-mid RPM ranges where you will spend most of your driving.

    Unfortunately, tuning a naturally aspirated engine for more power is tricky. Like Mike mentioned, gains at one part of the powerband often results in losses in another.

    Our EJ25 engines have been tuned/designed with N. American customer tastes in mind. The engines produce good low and mid range torque.

    The most cost-effective way (not necessarily the cheapest way in absolute $$s) is to turbocharge the engine. You probably get the most bang for the buck there.

    think I fixed this new coolant leak over lunch. lesson learned: do not trust your diagnostic skills when you're not a morning person and you're already late to work. ;-)

    I didn't fiddle with the upper radiator hose this morning because it was really hot, but obviously that's the best cause for a leak like I described.

    at lunch I popped the hood and gave the cool hose a wiggle-- yep, loose. checked the hose clamp... loose. fished around in my glovebox for this mini-screwdriver my mother-in-law put in my xmas stock a few years back and tightened it right up. I doubted I'd ever use this silly little thing but it works, bless her.

    more good news-- our execs announced today at the company xmas lunch that they're giving us another 1/2 day off for a good year, so I'm outta here at noon tomorrow. I'm gonna wash my car, she deserves it.

    That little tool was already worth the price.

    I get a half day tomorrow, too, plus Monday and Tuesday off for the next two weeks! Oh, and next Friday is my Compressed Work Schedule day off. Do I ever work? :-)

    I have to work tomorrow and this monday and the next monday! Oh well I'm looking forward to July 4th week though. :)

    By that time I'll be nervous waiting for the baby to arrive! :-)

    Did I mention I get 3 days of paternity leave?

  • After tomorrow, NO MORE WORK TIL 2002!!!!!!!!!!!!!!!!!!
  • c_hunterc_hunter Posts: 4,487
    Good old George W gave us feds the day off on Monday, which was cool. Now I have enough leave to take Friday off to finish my Christmas shopping! I'll be off until Jan 2, which is nice.

    I'd like to wash/vacuum my car tomorrow, but the weather will be in the 50s with wind. Not the best but I may brave it. Actually, I have to wash two cars -- my new Bean and the old wagon which my parents will be picking up. I'd wax too, but I am still waiting on a shipment from Klasse.

    I am glad to hear that you are finally in good shape, when I raed your earlier post I thoughtwhat the hell next.

    The reason I asked about the burn spot in particular was my earliest cars when I lived in Ireland were mostly Austins, They had an engine that had the bad habit of blowing the gasket out between 3 and 4 cylinder, the burn track in the head and block was sometimes so bad that the head or block or both were scrap.

    In the days when money was really tight I used to pull the head slap on a gasket and then maybe get a couple more months of driving. I got so proficient that I could have the head off and on in about an hour.

    Anyway like I said i am glad that the saga is over for you.

    Cheers Pat.

    Yeah but I'm going to miss the soap opera, "The Young and the Gasketless". ;-)

    BTW. what was the actual location of the coolant sensor? Hopefully the blown gasket was just a one time occasion.

    Cheers Pat.
  • ateixeiraateixeira Posts: 72,587
    Yeah, I hope you took a photo after all that! :-)

    I did, but you can't see it worth squat. I'll put a little arrow on the one pic that's in my imagestation album where the intake manifold is off, I could point out the area.

    -Colin
  • locke2clocke2c Posts: 5,038
    if anyone is interested... went ahead and tossed these on our regular webspace, didn't bother with imagestation.

    teardown pic from Saturday, arrow pointing at the temp sensor (184kb jpeg, 1280x960)
    the sensor is on the back of the coolant pipe that contains the thermostat. it is very well concealed with the intake manifold and other bits in place!

    pic of the loose connector, gonna kick my buddy's [non-permissible content removed] for this (184kb jpeg, 1280x960) this is a shot leaning over the passenger side fender, part of the intake plumbing already removed and a disconnected vacuum line can be seen as well. I'd remove much more to find the place it plugs in even though it's short length told me it couldn't be far.

    oh, and who is the fool doing all this stuff? here I am with my lovely (and patient) wife Lisa, april 2000 at my friend's wedding. I'm half-lit and 20 minutes from an unrehearsed speech in front of 200 or so. ;)

    How about Nitrus? tricky but will do the job
  • paisanpaisan Posts: 21,181
    Yep but that isn't a long-term, drivable solution. It will give you a boost for a short time, kill your engine, and isn't what I consider a viable option for anything other than a light to light race or 1/4mile drag strip car.

    -mike
  • ateixeiraateixeira Posts: 72,587
    Talk about a needle in a haystack, boy!

    This guy Kevin was running Nitrous in an Outback Sport, and the 1/4 mile times were pretty amazing for a 2.2l wagon. I'm not sure if he documented the installation, but you may want to search on i Club if you're truly interested.

    That really stresses all the engine internals, though, so any tiny failure could be catastrophic.

  • paisanpaisan Posts: 21,181
    A good guy. He has since taken the turbo and NOS out of the OBS. I think due to reliability issues. He's currently working with a FWD XT6 AT for 1/4 mile times.

    -mike
  • ateixeiraateixeira Posts: 72,587
    Really? Wow. Auto is actually good for getting consistent 1/4 mile times. Like for bracket racing, where you dial in a certain time and try to get as close as possible without going quicker.

  • Love the pic! Love the part about 20 min unrehearsed speech in front of 200.
    Too bad we couldn't get a tape of it.

    the wedding toast. One of the most uncomfortable moments of my life. Luckily I only had to do it once so far.

  • All prices include parts and labor, no taxes.

    LOF: $30.57
    30K service: $227.92

    I remember when Carol first had her Jeep serviced locally. Every time she had gone to one of the Baltimore area dealers, even for one of the routine services, the bill had been around $200 if not more. She had an LOF-style service done by the local dealer here and the bill was more like $30! She looked at the bill, looked at the service manager, and said, "did you do everything?" The only thing they didn't do was to pad her bill with a bunch of frufru ;-)

    Cheers,

    Colin, that is one [non-permissible content removed] of a spot to get at, could,nt Subaru with a little imagination have made it even worse.

    You can see how a part that probably does not cost a lot in the scheme of things turns into an astronomical repair bill because of some of the inaccessable places they choose to install stuff.

    Cheers Pat.
