pretty simple question but i imagine ill get a lot of responses
Did aus get the ER27, XT6 engine in anything??

And what were the differences between the engine generations specifically ea82 and 81

ER27 (2.7ltr) never made it to Aus in factory delivered vehicles but there are a few around. Mostly imported and running in VWs. They are essentially an EA82 with 2 extra cylinders. Each cyl = 450cc

If you're asking the differences between the EA81 and the EA82.. main thing is the EA81 has 1 camshaft with pushrods and over head rockers where as the EA82 has 2 camshafts (one on each head) and timing belts to keep camshaft timing. Both engines are 1.8ltr and have the same bore and stroke.

Here's a good source of info..

another question that should probably go in here

safari intake, myth?? Anyone got pics or details of one of these

Spider intake, specifically what did this come on?

Spider on 1987.5 and up Subaru Vortex's both NA and Turbo.

Rare and awesome, I think of them as the beginning of the ej
design Coming through the system.

Cheers

thanks for that H-top
Im gonna have a thankyou list as long as the book =D

Still wondering about the safari intake though

And now

Turbo heads, whats the difference between them and standard mpfi??
Are they the same with some porting done at the factory? Or made from totally different castings??

H-top · Post by **H-top** » Mon Dec 06, 2010 8:22 pm

No worries mate

EA82 MPFI and EA82T MPFI heads are exaclty the same, no different at all
except the oil supply, return and coolant return lines drilled, faced and
tapped for banjo fittings

and have the same woeful ports

cheers,
Sam

Anything like these?

This is of an EA62 engine from the FF-1 Coupe, 1.3L and made 92HP and 7000rpm

EJ22 with dual IDF's and a different distributor setup (looks like its an electronic distributor with a remote coil pack)

Another EJ22 (well heads) with dual webbers

More Qs

Blocks
Any differences between turbo and na?? Besides the holes for the head
On bothe the 82 and 81

steptoe · Post by **steptoe** » Tue Dec 07, 2010 7:18 pm

Gonna get you in a frenzy when we tell you that EA81 heads differed over the years, later having bigger valves. SCOOBIDOO also says he knows of three variants or generations of EA82 efi heads

Ea82 T blocks were essentially efi blocks that differed from carb with rear PCV vent that has a baffle cover plate screwed in behinbd flywheel, carby did not. Only turbo EA82 had the knock sensor I seen a few efi EA892 NA that not have it.

A kiwi fabricator / welder ...Dunbar was his name, once told me of the safari kit avail from Subaru in NZ the carbs were more directly over head ports

oh crap........
i know about the ea82 head bit
81 was a bit different, might leave that for a revision of the book, or until i can get my hands on every single generation of heads.

thanks for the block question wasnt sure if they had an extra bearing journal

ive heard they were on the possum bourne rally versions of the car

H-top · Post by **H-top** » Tue Dec 07, 2010 9:11 pm

EA82 heads came in 3 GEN's

and are identifiable in the following was

GEN I - EA82 cast into the head with nothing else

GEN II - EA82 cast into the head and underlined

GEN III - EA82 cast into the head inside a box

so the GEN II were factory in later engines but the GEN III were only
available as replacement heads, never fitted as factory.

Only the EA82 engines with Knock control had the sensor though most had the
hole with no thread tapped to fit the sensor. And all with were turbo.

the EA82MPFI Turbo had a slightly longer block, coupled with different pistons to
reach the super low CR of 7.7 to 1

cheers,
Sam

Turbo blocks use lower compression pistons but the bare block appears the same.

I'm 100% sure of this in EA82Ts. I have never pulled my EA81Ts apart but I'm 99% sure they would be the same.
