Later this year subaru is going to announce their high-tech H4 boxer diesel engine. I love diesels, and have always wanted an old wagon with 4WD and a diesel engine that got over 50mpg, but no such thing has ever been made, to the best of my knowledge. My question is this: Do you think it will be possible to install one of these in a EA82 series car using the EA to EJ adapter plate that Allied Armament sells? I expect that in a few years wrecked H4 diesels will show up in junkyards, and I could get a motor for about the price of a VW TDI diesel ($2000). Perhaps I could just make a custom adapter plate and install the TDI itself?

50mpg+4WD+150 hp turbo diesel= the ultimate adventure touring car

There's no way to tell until it gets released.

 

Also, if you look at the designs for the motor, the Turbo sits below the engine. Custom crossmember maybe?

 

Only time will tell.

I've heard that it will be a European model only, it's not coming to the USA.

Bummer, perhaps they will show up as JDM engines...

still maybe

w00t for turbodiesel! I wonder if the turbo could be relocated for easier retrofittification in the older models...

Unless you plan on spending your lifes savings I reckon you'll have to wait at least a couple of years after the engine has been released into the market before you will be able to pick one up. So by then you never know what there might be avalible to put one in your car..

I'm sure it'll have the same bellhousing as any other EJ engine. I'd be worried about wiring. the last all new engine they put out (EZ30R) has an immobilizer system built into the ECU/harness, that makes it virtually impossible for the engine to run off the stock ECU in a car other than the one it came in.

 

but I agree...would be way cool.

isnt it similar to the ej20 block? i read in an artical where that they say petrol block would be able to handel the stresses of being used as an diesel engine? that artical i read was an while ago tho?

Everything you hear now is purely speculative as FHI has really yet to release any specifications on it.

 

As for sharing an EJ20 block, I highly doubt it. Examine the pictures, there is SO much different there.

it may look like it shares a block, but to be a diesel there is so much beefing up that is needed it needs its own sepcific block

 

 

nipper

well, that cutaway shows it having timing chains, so it can't have too much in common with your typical EJ block...

I doubt it would be a normal EJ block as well.. I don't see a point in modifiying a block when you could build a diesel designed block that is going to do the job much better and for longer.

Plus, hows a EJ block suppose to take 20 to 1 compression ratio

the peugeot 505 has a form as a deisel 4x4 wagon. Looks cool actualy.

Wow! I've never heard of that. I'd bet they're impossible to find over here in the states. I found 2 links with more info:

... never knew that, interesting.

I have seen a Peugeot diesel sedan in person, but never a wagon. That's very cool.

 

Tangential comment: The one I saw was running on biodiesel made from fish oil. You know how burning used frier oil makes the exhaust smell like french fries? Well, you can imagine the horrid odor that this thing made.

a turbo deisel!!!!!!!!! thats freakin cool. kinda trendy tho. but would be cool to see. i would bet money on that engine never making i t ot the states....we never get anything cool.

EZ30R has 'em...it's EJ-based...

 

(Okay, that was out on a limb)

um...no, it's not. the only thing similar is the bellhousing. and the concept that it's horizontally opposed. it was completely redesigned, from the ground up. with a completely different bore/stroke ratio to any other subaru motor. the cyl. are closer together (made possible by the smaller bore).

Okay. I'll take your word for it.

 

Good to know...

Not trendy at all. Lower CO2 emissions, higher torque, lower sulfur than diesel of old, plus you (should most likely) have the option of running biofuels (biodiesel = carbon neutral).

All the current press about global warming, and reducing dependence on foreign oil are only helping to make a strong case for bringing more diesel options stateside.

At least I hope so.

Any Comments are Wellcome!

awesum threads. i no this has nothing 2 do with the diesel subaru engine.

But i luv that subaru motor bike right at the start. is that 1 made by an person? or is it genuine subaru?

there were also vw quantums with the 1.6td though they may not have come as synchro. its possible to build one though. also there was an audi fox wagon(very close to a quantum) with a diesel 5cyl IIRC.
