How old is the boxer engine?
Can anyone tell me how old the boxer engine is? I know that Subaru used to make a 1.8 liter and I believe that it was fuel injected; did Suabru ever make one smaller than that?
Well the boxer engine itself is very old. Used heavily by VW and Porsche. Used by alfa and Ferrari, chevrolet etc etc etc. Not to mention almost every light aircraft engine. But if you want to be Subaru specific, its been around for awhile also.
The current 4 cyl engines are all EJ series engines. These were made in 1.6, 1.8, 2.0, 2.2 and 2.5 liter varients
The current 6 cyl engines are EZ series and came in 3.0 and now 3.6 liters
The EG engines were the 3.3 liter boxer 6 cyl found in the SVX.
The ER27 was the 2.7 H6 found on the xt-6 (essentially the EA82 with 2 more cylinders)
The EA series is what we had before the EJ series. They came in both push rod and SOHC verisons. They have fuel injection and carbureted models. These ranges from 1.0 liter to a 1.8 Also some were turbocharged.
And I can't remember the rest....

You know, the funny thing is that most Subaru afficionados say they love the Subaru engine's torque but the simple design fact of the boxer engine as Subaru employs it is that it is an inherently low-torque design.
The Subaru engine is extremely oversquare (bore diameter larger than stroke length) for packaging reasons, and highly oversquare engines are, all else equal, WAY less 'torquey.'
I still like them, though.

I never would have guessed that the boxer engine actually had a lower torque curve. I've driven manuals pretty much all my life, and my first impression with the Baja (5-speed) was that it had lots of guts from a dead stop. I had a jeep with the straight 6 and it had a lot of torque as well, but the I would have sworn that the Baja was more gutsy.
Interesting....

I think the illusion of them being so torquey is the fact that the motor is a real thumper as it is a 2.5 liter 4 cyl while people are probably comparing it to 1.8 liter hondas. Also the SOHC 2.5s do have good low end and great midrange torque. If you drive an older DOHC 2.5 there is a noticable difference in power bands.

Also don't discount the LOW LOW LOW center of gravity (the WHOLE reason for the Boxer) a lower center of gravity will give the impression of tons of Torque (I used to ride snowmobiles and you always felt like the dang things were gonna TOSS you off the back- the engines that stay closer to the ground feel like they can slip right out from under you) I know it sounds strange- but that is where a lot of the feel comes from.
I always wanted a BRAT, I had a Baja (sold) Now I have an Outback
