I have an ea81 engine hanging in a shop, for my brat to be used as a temporary engine, however, the distrubuter from the hydroluc moter is too big, even though their both ea81's why are the distributers diffrent sizes? anyone know? thanks

hmm thats wierd.... i took the one outa my hydraulic motor and stuck it in my pushrod motor no problem.. they were the same size..

 

one disty was a hitachi (out of hydraulic motor) the other was a nipondenso (out of pushrod motor)

 

so not sure why one would be bigger than the other...

yeah, i know what you mean. the one from a 2wd hatch was too fat for my ea81t. but i dont know why there are 2 shaft sizes?

yea it's really weird, it's not a big enough diffrence to be obvious, it just seems like maybe the shaft hole is dirty... but then you notice it's diffinataly diffrent. Would the moter having a Carter-Webber orginally on it have anything to do with it?

Shouldn't - the carter/weber came on 83/84 2WD's as I recall. But the manifold and carb were the only differences - not the block. That's very odd tho. Never heard of that. Maybe someone who has built EA81's a few times can tell us.

I've pulled lots of distys and installed lots of em, and never seen a difference like that...

 

any possibility that the engine could be a JDM variant?

 

just throwing out thoughts.....

JDM?

Japanes Domestic Market.

 

could have been an imported motor that was slightly different...

never seen one, but you never know....

hmmm interesting, ok thanks everyone!
