Been doing an engine build on an EJ25 lately.
Thought someone would be interested in seeing the weird ways they build these engines. two halves to the cylinder block with a short approx 100mm stroke
The halves are held together by a few 12mm bolts and the mega tight head bolts. To remove the pistons have to take plugs out of the block and remove the gudgen pins through the side. Its a really well thought out engine nothing confusing at all.
Even the crank is pretty unconventional its half the length of a normal one.

horray for crazy boxer design!

subaru boxers aren't anything odd. the crank is so short because the engine is only 2 cylinders long... if you want to freak out,pull down a porsche motor. everything is modular. split block,individual heads per cylinder,individual barrels. beautiful castings too. the block is a work of art,and the heads have the straightest ports I have ever seen in a production engine.

i've seen a few dismantled porsche engines at my olde work, they're pretty crazy,

man was i tempted to steal a few intercoolers!!!

but that would be no question who stole it since i was supposed to be overnight security!

I know they are old hat but its really intreging to look at the way they have designed the blocks. I don't know bout the porsche engines but the EJ is really well thought out. I assume the porsche uses a simliar gudgen removal method or do you remove the barrel first like a volkswagon?
Wonder why other manufactures havent tried the flat four layout?
No obvious reason other then cost that I can see.

Cos it's expensive and takes up a massive amount of room.

Also the general car buyer wants a cheap piece of crap that they can rev out to get power instead of a nice torque (and really cool sounding!) engine.


Also a lot of good spare boxer engines (particularly EA82T's and EJ20T's) get snapped up by aircraft enthusiasts.

Alfa Romeo ran a flat 4 in the old Sud's and Sprints (common platform, completly different looking cars).

The short block allowed then to fit the engine infront of the box in a north south arrangement and still run fwd.

My old man had a sud when i was about 12 and still carries on about how well it handled in really tight turns and still bitches about the massive lack of torque and how shocking it was in high speed sweepers
