Subaru Engines?


Recommended Posts

Can someone tell me if there is a reason behind the name of the EA series engines and the number that follows?

 

Like the EJ series makes sense. EJ18 is 1.8, EJ20 is 2.0, etc.

 

But what is the EA81 and EA82 and EAwhateverthehellelsethereis

 

? Any reasoning or was it just random by some japanese dude? lol :clap:

Well in the 60's I think they used a EA63, in 70's they had EA71, then there was the 80's with the EA81. Then they modded the EA81 to fit over head cams and called it the EA82..

Kind of a pattern there... But I have no idea really.

What ius interesting is on the heads of both the EA81 and EA82 they just have "E81" or "E82" without the A.. :-\:confused:

Dunno... maybe the A is the 1.8 liter block, and an E is a head -- the 81 is the OHV, and the 82 the OHC.... Nah. that doesn't make much sense either....

 

Then there was the ER27, right? Which is the 6 cylinder version of an EA82. Which actually is 2.7 liters I think. Hmmmmmm :confused:

gee I love the B202 in my saab its so simple B-B series engine,20 -swept volume 2.0L,and finally 2-number of camshafts.Then turbo just has an extra T(although its not on the block cause the block is the same for turbo/non turbo.Heck so is the bottom end.Just different pistons and the turbo has sodium filled exhaust valves...definatly a lot of money in designing the car...At least the bottom end can support well over 650 hp...

 

oh oops Ive begun rambling...oh its 12:21...Maybe me should go to bed..
