Towel Rail Posted December 10, 2007 Share Posted December 10, 2007 I've been hearing the rumors for years, but I'll let some real-world testing occur first. If they turn out to be alright, I might be tempted to buy an actual "new car." - Scott Link to comment Share on other sites More sharing options...
subiemech85 Posted December 10, 2007 Share Posted December 10, 2007 if it comes true, sign me up for a baja with d/r 4x4 Link to comment Share on other sites More sharing options...
SakoTGrimes Posted December 10, 2007 Share Posted December 10, 2007 if it comes true, sign me up for a baja with d/r 4x4 You know they killed the Baja off last year..... right? Link to comment Share on other sites More sharing options...
bulwnkl Posted December 10, 2007 Share Posted December 10, 2007 if it comes true, sign me up for a baja with d/r 4x4 I'm with you! And yes, Sako, we know the Baja's discontinued. OTOH, so is the d/r transmission, and the diesel engine isn't quite real yet, so why not wish for what we're wishing for? Link to comment Share on other sites More sharing options...
Chip Posted December 10, 2007 Share Posted December 10, 2007 My 98 O/B clacks so bad I don't need a diesel !! All I'm missing is the black smoke and the smell. Link to comment Share on other sites More sharing options...
uniberp Posted December 10, 2007 Share Posted December 10, 2007 who is gonna get one or does any slick rick out there already own one? I live in america and I hear it's in europe first, you lucky bastards! I for one cannot imagine a sleeved aluminum diesel engine. I've seen the pics, and wish them the best, and if it works, I'll get one. But until then, I just can't see it. Link to comment Share on other sites More sharing options...
Towel Rail Posted December 10, 2007 Share Posted December 10, 2007 I wonder if they'll use a compacted graphite-iron block like the new Duramax... the rods and pistons are the really critical part to beef up for diesel engines. Link to comment Share on other sites More sharing options...

eagleb Posted December 11, 2007 Share Posted December 11, 2007 They either need to expedite the diesel or bust balls on a hybrid, otherwise sales will become inversely proportional to the cost of gasoline Link to comment Share on other sites More sharing options...
crazyhorse001 Posted December 11, 2007 Share Posted December 11, 2007 How come? What's the issue you're seeing? Diesels operate at incredible cylinder pressures & temps. Simply sleeving an existing block, especially an aluminum one, wouldn't handle the stresses. Just ask Oldsmobile. Link to comment Share on other sites More sharing options...

crazyhorse001 Posted December 11, 2007 Share Posted December 11, 2007 That certainly looks like an Iron block to me. Kudos to Subaru for getting back to thier rugged roots! Link to comment Share on other sites More sharing options...

xbalancex7 Posted December 11, 2007 Author Share Posted December 11, 2007 that is beautiful. yes pressures will be high due to diesel nature. I pray that this does deliver to my hopes and expectations. This would almost be the perfect engine in my mind. I do believe pressures and head gaskets could be an issue, but with enough design and planning it has to be possible. That is the only weakness that I could see. We just need better gaskets and better gasket surfaces to work with, there HAS to be a way...! Link to comment Share on other sites More sharing options...

Oh, so it's just a generalized concern of whether they employ qualified engineers or not. I thought someone was inventing some issue with using aluminum or sleeves or something.

NAH that issue has been around a whils, and some mfgs (harley is one, rover is another) has a problem with sleeves shifting. SUbaru only gets that if you drive a few miles with car temp pegged. nipper Link to comment Share on other sites More sharing options...
bulwnkl Posted December 11, 2007 Share Posted December 11, 2007 OK. I guess the only aluminum-block sleeved diesel engines I've dealt with first-hand are from Mitsubishi (great turbo diesel in a pickup from the '80s as well as a whole bunch of construction equipment). The heavy ag and industrial stuff I've put my own hands on is all either iron w/sleeves or sleeveless (bad experiences). Link to comment Share on other sites More sharing options...

uniberp Posted December 11, 2007 Share Posted December 11, 2007 That certainly looks like an Iron block to me. Kudos to Subaru for getting back to thier rugged roots! The photo looks like it, but the rendering shows a sleeve. I don't doubt for a minute that it can be done, but the question is not whether "subaru hires qualified engineers". My question is whether they can produce castings of sufficient strength to allow a 2 piece block connected by long bolts to absorb the stresses inherent in diesel combustion, at low enough cost to sell enough to recoup their investment and make it worthwhile to continue building them. If I thought a Rolls was worth it, I'd seriously shop for one. Link to comment Share on other sites More sharing options...
Gloyale Posted December 11, 2007 Share Posted December 11, 2007 That certainly looks like an Iron block to me. Kudos to Subaru for getting back to thier rugged roots! ???? That block doesn't look Iron at all? Block and heads are beautiful shiny Alloy. I think Subaru have always, and probably will alway use alloy blocks. An Iron boxer would be VERY heavy for the front end of a subaru. Link to comment Share on other sites More sharing options...

A two piece block design is WAAAY more stout than conventional main bearing caps. In conventional straight and V diesels, the force actually tryies to push the main caps away from the block. The main caps rely on bolt as well, and it all works as long as they are stout bolts. Now in a Boxer, where would the crank possibly go? It's sandwiched between two giant slabs of metal. More bolts and more solidly connected than any main caps. Diesel Boxer sounds like a marriage made in heaven. Link to comment Share on other sites More sharing options...
xbalancex7 Posted December 13, 2007 Author Share Posted December 13, 2007 well I hope gloyale is right, it does sound like a marriage made in heaven, but if it so kick rump roast how come it hasn't been done before? I mean I just find it hard to believe that alll through the years of diesel production it just wasn't thought of, if it wasn't then damnation, lets kick it into high gear and make tons of diesel powered boxer engines!!!!
