subaru engines : Hi, I am considering buying a used Subaru. I've heard that there are low-mileage engines for sale through dealers. What I don't know is what years those engines fit. The last Subaru engines I worked with were the 1600 and 1800 ones. I will be buying a 4 wheel drive, stick wagon. Just don't know what year I'll get.Does anyone know if Subaru is developing an entirely new engine? Ihope so, because that is one reason I am hesitating buying a new one.I have never thought of their engines as being in the same class asToyota or Honda - definitely not as smooth or quiet, and probably notas fuel efficient. Even though the new models seem much more solid andhave much quieter interiors than the my '88 GL, I can still hear thesame distinct high pitched growling noise, which suggests the engineshaven't changed all that much.. However, the Suby engines (well, at least my '92 1.8l) havetwo overwhelmingly positive attributes, in my mind: 1) Non-interference. Break a timing belt, no big deal. Break a Honda timing belt, you're SOL, and buying at least new valves, in all likelihood. Maybe a new engine.
subaru engines : 2) Emissions. Our Vancouver-area "Air Care" program tracks Pass and Fail rates, and the Subarus are #1 on the list! 3) Easy to work on. Not an overwhelming positive, and the newer Suby engines may be more complex than my 6-y.o. one... Anyway, I like the wrench-friendliness of my SubyFrom: ()Subject: Re: Subaru engines Newsgroups: Date: 1998/09/19 OK, I have just one monkeywrench to throw into the works. (Sorry to cast ashadow, but I thought the info was worth having)A Subaru and engine knowledgeable friend made an off-handed comment abouthow unlikely the new Flat 6 would be to come to America. When I asked himto explain he gave this general description:The new 3.0L-6 is a "Lean Burn" type engine, meaning that they intentionallyrun the air/fuel mix toward the lean side. This makes the engine burnhotter and (when controlled) generates more power. Anyone who's overboostedan engine and cooked it off due to a lean condition can tell you that theengine was making great power right before it went. Subaru's (and othercompanies have done this too) idea is to use the computer's power tocarefully control the reaction and intentionally keep the engine in the leanzone without "overlean" that would cause detonation.
subaru engines : This is great for power, probably how they're able to generate the rumored240hp from only .5 liter more than my RS engine (which only produces 165) -Plus because you have 6 cylinders (which means pistons 60 degrees apartinstead of 90 in a four) the engine will be much smoother and have poweroverlap (two pistons whose power stroke overlap in the timing).Here's the bad news - Lean burn engines are great for power, and theirREALLY good for reducing hydrocarbon emissions. BUT - They produce MORE NOxemissions than a normal air/fuel mix of the same displacement. InCalifornia for sure, and soon in many other states and possibly at thefederal level, the NOx emissions are the current evil-du-jour and the targetof new legislation. The smog Nazis here have gone so far as to implementDyno smog testing to help catch more NOx polluters.As a friend of mine is opt to say: "He who throws the monkeywrench mustretooth the cog"The one shining glimmer of hope is this: In California, Subaru's and all AWDcars are exempt from Dyno testing because CARB in its infinite wisdom andforethought specified 2-wheel dynos for the smog program... It IS POSSIBLEthat the increased NOx emissions would not be detected by tailpipe tests,only when the vehicle was on the road under load. So, the engine mightsneak through...
subaru engines : --Mike Herbst Brilliant Red 2.5RS - SPD TunedStock Exhaust, Aftermarket Driver-- Remove NOSPAM to reply --Well, according to conventional wisdom, the flat-6 is being developed*specifically* for the US market, as it's easier to gain power that waywhile meeting emissions than with a turbocharged engine.--+-------------------------+----------- -----------------------------------++--- ----------------------+----------------- -----------------------------+Supposedly, Subaru will introduce (or has in Japan already) an H-6 motorwith the all new Legacy/Outback for the 2K model year . Although it maystill possess the characteristic "Subaru whir", it should be noticeablysmoother. I just skimmed an article (forget which auto mag it was...), andI believe it said the horizontally opposed 6 cylinder engine is one of thebest balanced cylinder layouts. What about Forester??!! BTW, will there be a big differencein performance, etc.. between the 2.5L H-4 and that rumored 3.xL H-6?from everything I've heard the whole 6 cyl program is meant to be a way togive the American market more power without giving us what we really want -TURBOS!! but yes we should see greater hp and torque numbers with the sixes.I'm on my second Sube, and the first one's engine was practicallyindestructible. I won't tell you the abuse I put it thru, but suffice tosay I had to retire the vehicle due to rust, not the engine wearing out.
subaru engines : I don't know of any direct-drive KR-2 setups, but I am aware of aCanadian fellow who has built and is currently flying a direct-driveSubaru-powered...uh... either Quickie or Dragonfly (I forget which). Ithink he's going to sell Subaru conversion kits. I'll look it up in themagazines tonight and post more tomorrow.I, too, would like to hear more about other's experiences withdirect-drive Subaru engine setups.I have bought a couple of these for my various subaru experiments (incars unfortunately). They are called "import engines" and can bepurchased at through many junkyards. If I remember correctly they aresupposed to have less than 50,000 miles on them. Last I checked a 1600cc motor for a late model subaru cost about $500 including allaccessories. I do not know how much the newer engines are going for.I too have seen these engines advertised, but have heard that the mandated replacement is 50,000 kilometers, just over 30,000 miles. Only trouble is, if you had to change your engine in you car at 30,000 miles, what kind of care/maintainence would you do? Rumor has it that the engines don't get even simple oil changes. 30k miles and same oil, could be pretty worn...
