kellyray Posted January 27, 2009 Share Posted January 27, 2009 Alright I got some bad news! I took my brat down the road for the first time last night and I'm convinced that the motor is knocking!!! . I honeslty cant be mad because it was given to me but Im thinking before I throw a rod through a fender i would just park it and rebuild it?? It sounds like a main bearing knock instead of a rod knock. How hard are these little motors to break down and rebuild? I'm guessing I will have to split the case to replace main bearings? Does that make it hard to do? Has anyone have any experiance completely overhauling a EA81? Thanks Kelly O. Quote Link to comment Share on other sites More sharing options...
mdjdc Posted January 27, 2009 Share Posted January 27, 2009 I've done an ea82 and an ej25. They aren't all that much different than the one you have. Take your time and torque to exact specs and you should have a great rebuild. Make sure the crank isn't scored and that there is no damage to the rod. No sense in rebuilding and having the same problem when you are done. Damage should be visible. Good luck Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 My opinion is to find a good EA81 with a 4spd dual range hooked to it from a 2nd generation car and swap it all in! That would solve the problem of turning bigger tires!! Quote Link to comment Share on other sites More sharing options...
subystomper Posted January 27, 2009 Share Posted January 27, 2009 Sounds like an EJ Swap would take care of everything. Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 Sounds like an EJ Swap would take care of everything. That would be sweet too! But it would also be a bit more of a challenge because it doesn't fit too well! Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 Bratman18 will everything bolt up? Do you know what all i would have to replace? I guess Im refering to cv axles. will they all fit into a different tranny? and the rear drive shaft? Tranny mounts? stuff like that?

kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 subystomper i dont want to sound completely retarded but what a EJ? I know its a motor but what kinda motor? what does it come out of? Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 Ok EJ is a motor out of a Legacy/Impreza and will require quite a bit of mod to fit. As far as I know yes an EA81 and 4 spd Dual range will bolt right in. Some of the '81's came with that setup so it should be a direct bolt in!

kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 Maybe sometime ill get the balls to just tear into it. i have never messed with a flat motor like this. Maybe i can find a motor and tranny with a dual speed at a wrecking yard. I know where there are 2 other brats i can steal parts off of. I know that one of them is a 1600cc and not sure what the other is, but the other one caught fire a long time ago. If the motor isnt stuck ill think about swaping it if its a 1800cc Quote Link to comment Share on other sites More sharing options...

Most any Brat or wagon or hatch will have the EA81 and 4 spd dual range tranny as well. Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 it was brought up before but is it a problem if the motor thats in it now has the starter on top? If i get a different motor with the strater in a different place everything else should bolt up right? Quote Link to comment Share on other sites More sharing options...

Yeah if you get the setup with the dual range tranny attached, it will already have the starter off to the lefty a little bit. And yes it will all bolt right into place Quote Link to comment Share on other sites More sharing options...

kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 any brats ever fuel injected? if so what year? Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 any brats ever fuel injected? if so what year? no none ever came with fuel injection, but you can do a conversion using the system that a Loyale uses. That's what I have and I love it! I have the stock pushrod, EA81 motor with the Loyale fuel injection system on it. A few others on here have the same set up. The hardest part is the wiring Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 i dont mind sticking to a carb! I would rather not have to deal with all of the electronics. I like old fashion. lol. I still need to figure out if i have a EA81 or EA71. Quote Link to comment Share on other sites More sharing options...

I still need to figure out if i have a EA81 or EA71. Somewhere either on the top front passenger side of the block or near the back, there will be a stamp that says EA81 or EA71. I fyou could take a pic that would be great. Especially to show the placement of the starter Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 http://www.ultimatesubaru.org/forum/attachment.php?attachmentid=6081&d=1232587402 Heres one pic, i know its not very close up but it does show the top of the starter. Its right underneath the mount that goes from the firewall to the tranny. can you see it? its behind that red fuel line Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 Yeah it actually looks like it's off to the side. If you can , get some more pics and search for that stamp Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 27, 2009 Author Share Posted January 27, 2009 ok, what does it mean if it is off to the side? Quote Link to comment Share on other sites More sharing options...
bratman18 Posted January 27, 2009 Share Posted January 27, 2009 ok, what does it mean if it is off to the side? I think it means that there is a better chance of it being an EA81. But not positive on that. Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 30, 2009 Author Share Posted January 30, 2009 Hey Gents, I have been trying to figure out what motor I have in my brat. I did find some numbers by the disty where yall told me to look. This is what i found. NO 924781. Im not to sure about the NO part it was very hard to read but im positive about the numbers. Does this mean anything? Does this mean I have a EA81 since the last numbers are 81? Any info would be very helpful! Thanks, Kelly O.

bratman18 Posted January 30, 2009 Share Posted January 30, 2009 I have no idea what those numbers are. There has to be a stamp there someplace that says EA81 or EA71. It is only a couple inches long at the most, and is a stamp. Maybe someone else will know what that number means. Quote Link to comment Share on other sites More sharing options...
kellyray Posted January 30, 2009 Author Share Posted January 30, 2009 Thanks, The NO is a part of the cast when the manufactor the block, the numbers are stamped. Maybe its just a serial number? So it should be possible to see the EA?? without taking anything off like the intake manifold? Quote Link to comment Share on other sites More sharing options...
