RedNed Posted December 28, 2003 Share Posted December 28, 2003 This should get some feedback. I want to know if Subaru ever made a desiel engine. I want to put one in my Loyale and convert it to run on discarded fryer-oil(or canola, but fryer-oil is freer). I've done some reasearch and I think the spare tire area would be a great place to put the auxilary tank with easy access to coolant lines to preheat the fat. There are quite a few conversion kits on the market but what fun is that. A little duck tape and we're ready to go. The biggest hiccup is you have to start with a desiel. I've never heard of Subaru desiel in North America but the rest of the world is far more enviromentally minded so maybe I should look in Oz or Europe. If anyone has any info...or opinions.....fire away. Later Link to comment Share on other sites More sharing options...
Dante Posted December 28, 2003 Share Posted December 28, 2003 I'm a relative newbie to Subarus, but have been a Diesel/biodiesel freak for years. I run biodiesel in my 2000 VW Golf GLS. I know of a few people who run straight vegetable oil (SVO), but I don't want to mess with a second tank, etc. I don't think Subaru ever made a Diesel for a car. Try a search. There was a thread about Diesels in the "newer generation" forum I posted in. IIRC no one could come up with any evidence that Subaru has ever built an automotive Diesel. As far as I know, there has never been a production Diesel boxer engine (although there was a cool experimental Scottish yoke design). The good news is GM/Saab/Subaru are working on a Diesel boxer for the new saab 9-1 or 9-2, which will share the Impreza platform. Until then, get yourself a Mercedes or a VW. BTW, Subaru/Fuji Heavy Industries makes some excellent small Diesel engines, which they sell under the "Robin" brand. LINK Link to comment Share on other sites More sharing options...
Hondasucks Posted December 29, 2003 Share Posted December 29, 2003 an EA81 Diesel is rumored to exist, used in FHI Forklifts. For some interesting biodiesel info, look at http://www.veggivan.com Link to comment Share on other sites More sharing options...
archemitis Posted December 29, 2003 Share Posted December 29, 2003 something tells me a whole lot of compression and some 80s vw parts and a subaru diesel would be pretty easy. ea81 all the way. Link to comment Share on other sites More sharing options...

MilesFox Posted December 29, 2003 Share Posted December 29, 2003 how about a stroker ea71, with fat case heads. using ea81 crank or rods? or an ea81 with spfi postons(or whatever qmans has for 9.5 compression) and use ea81t heads, and make a diesel the ea7 ans 81 motors have studded heads....

GeneralDisorder Posted December 29, 2003 Share Posted December 29, 2003 Don't think so Miles - diesel needs around 20:1 compression. As I recall diesel engines run anywhere from 20:1 to 100:1 compression. I don't think a stock EA81 block would handle that kind of pressure without some serious work. My guess is that if an EA81 diesel did exist, it wasn't really an EA81 - would need a complete redesign to last any legth of time. Diesel runs hot and high pressure. That is the cost of sponteaneous combustion. But it's also why they are so efficient... GD Link to comment Share on other sites More sharing options...
archemitis Posted December 29, 2003 Share Posted December 29, 2003 yah, but chevy turned their v8s into diesels, and they worked. i didnt say they wroked good, but they worked. several companies have converted their casoline engines to diesel. especially in the 80s.

Nug Posted December 29, 2003 Share Posted December 29, 2003 I think three main bearings would end this experiment pretty dramatically. That and the size of the cute little connecting rods. Link to comment Share on other sites More sharing options...
Soobadooba Posted December 29, 2003 Share Posted December 29, 2003 Here's some folks who apparently are (or were) kicking around the idea of converting an EA81 pretty seriously. Go to this link and scroll down to message #30775: http://groups.yahoo.com/group/airsoob/messages/30701?viscount=100 Don't know what the outcome was, or if there even was an outcome (didn't read it all), but they bring up some interesting points...things that make you go hmmmmm. This group is all about putting Subie engines in aircraft. I've gotten some pretty interesting info from this site. -Louis- '91 Loyale 4wd 5spd Wagon Link to comment Share on other sites More sharing options...
RedNed Posted December 29, 2003 Author Share Posted December 29, 2003 I've searched lots of other stuff and it works great. I didn't even think to use the search engine for this....it seemed too obscure....I won't make that mistake again. Thanks for the feedback. I'm not sure what I will do with it but cool.

speedbump Posted February 19, 2004 Share Posted February 19, 2004 You might want to think about a cummins B3.9 or a Yanmar 3cyl,but you wont get highway performance out of either.I put a B 3.9 in a cj7 and it killed off road, but only did about 80 km/h on the road with stock gearing.Also,btoh of these options are EXTREMELY heavy,so you would have to beef up the front end.

Snowman Posted February 19, 2004 Share Posted February 19, 2004 If you were going to swap in one from another make, I think the way to go would be the 2.4 Toyota diesel, with the turbo from their gas engine grafted on. You would need to get some different gears though, as the Yota trucks with that engine didn't like to run past 65, and even that was a stretch.

asavage Posted February 20, 2004 Share Posted February 20, 2004 Originally posted by archemitis yah, but chevy turned their v8s into diesels, and they worked. i didnt say they wroked good, but they worked. The '78 Olds 350 gas->diesel conversion wasn't reliable until '83, the last year of production. Until then, they had broken crankshafts, blown head gaskets, and misc. injection pump ills. That engine did more to kill off automotive diesel sales in the US than any other make. Through '81, the only Chev diesels were that Olds conversion engine, and the Isuzu diesels in the Luv (and maybe the Chevette?). In '82, Chev introduced the 6.2l engine (later, 6.5l) in their light truck line, but it isn't a conversion engine, it started life as a real diesel design. several companies have converted their gasoline engines to diesel. especially in the 80s. Hmmm. I can only think of the Rabbit, and that's not a good engine, either. Can you say "blown head gaskets"? I thought you could. They became a lot more reliable after '83 or so, with the fourth (or fifth?) head redesign. I had an '80 that was very worn, when I tore it down it had .030" bore taper. You read that right. That was the most worn engine bore I've ever seen, for an engine that was running. I sold the car to someone who wanted it for a gasoline conversion. I was the 2nd owner. It wouldn't fit in a Subaru, but the Nissan LD28 straight Six, sold in the US in the 810/Maxima from '81-83, is a honey of an engine. NA, it's 80 HP SAE. It is also used in a couple of Nissan truck chassis, though I have no info on that. It flat ran away from my 3.0l MB, left it in the dust. Very long legs, great high speed road trip car. Getting to be a bit hard to find these days. Like to shred its injection pump timing belt, leaving the engine dead. Loosely based on the famous 280Z engine, yes it's OHC. Very smooth runner, similar to a VW TDI in that respect. But fairly long by today's standards. I bought one from the original owner in '95, sold it to a friend in '99, and am getting it back as soon as I finish fixing up his new '93 Loyale. Looking for a turbo retrofit in its future Link to comment Share on other sites More sharing options...
Hodaka Rider Posted February 20, 2004 Share Posted February 20, 2004 Not to get OT, but some of the early Rabbit diesels were very good. We had a few of them, put lots of K's on them. We had a '78 4spd and an '83 5spd, and the '78 would run circles around the '83. Never heard of major cylinder wear in them before, either. I guess it's all in the maintenance (dad was a stickler).

I saw a FULL SIZE 3/4 ton camper special Chevy, like mid 70s style, with a FOUR CYLINDER, NATURALLY ASPERATED Isuzu Diesel in it, and it looked VERY factory. It was a BIG 4 banger, it didn't look like the little itty bitty 4 cylinder they used in the Isuzu trucklets. Link to comment Share on other sites More sharing options...
bigjim5551212 Posted August 28, 2004 Share Posted August 28, 2004 When the original VW Beetle came out, the Germans developed a diesel flat 4 for it. There are pictures around. I will do some looking. Link to comment Share on other sites More sharing options...
bigjim5551212 Posted August 28, 2004 Share Posted August 28, 2004 Here is something I found today. Wednesday July 7, 01:06 AM Japan’s Fuji Heavy to develop diesel engine for cars in Europe, China - report TOKYO (AFX-ASIA) - Japan’s Fuji Heavy Industries Ltd, maker of Subaru brand cars, is gearing up to develop its first diesel engine and plans to start selling cars equipped with the new motor in Europe in around 2008, The Nihon Keizai Shimbun reported, without citing sources. In addition to boosting business in Europe, where diesel-powered vehicles are very popular because of their high fuel economy and lower carbon dioxide emissions, the automaker hopes the engine will also help to increase sales in China, the business daily said. Diesel vehicles are forecast to account for more than 50 pct of new car sales in Europe in 2005, following the European Union’s implementation of a tough emission control regulation, the Nikkei (news) said. Sales of diesel cars are also expected to rise in China because the government there announced in early June that these and hybrid models will be at the core of its automobile environmental technology policy, the report added. Fuji Heavy sold around 580,000 cars worldwide in the past year to March, 80 pct in Japan and North America. The company considers raising sales in Europe from about 50,000 units in fiscal 2003 and increasing business in China as key to its expansion, the report said. A Fuji Heavy factory in Gunma Prefecture, Japan, is expected to make the 2-liter engine. About 30,000 diesel engines are expected to be made annually, for use in Subaru’s Legacy, Forester and Impreza series of cars. Link to comment Share on other sites More sharing options...
Dante Posted August 31, 2004 Share Posted August 31, 2004 Oh man! A direct-injected turbodiesel hybrid would get awesome fuel economy. I average 44 mpg driving between Seattle and Bellevue in my 2000 VW Golf TDI and go over 50 on highway trips. It would be awesome if the new Sube diesel would fit into the older platforms.
