My first subaru! 1984 GL Brat


Recommended Posts

I think I was planning on dragging Carl down with me to Evans Creek next weekend (saturday) to come see the hatch patrol in action! (and meet some of the guys)

 

I have known Carl seince about second grade (somewhen like that)

and he used to live a block away from me for about 11 years, untill '99 when we had to move-

 

but we are still best friends, and we hang out all the time-

 

see ya soon!

Yea, I was thinking about lifting it, because I want a 4wd vehical that will be useful for times when it snows 2 feet over night. We ripped the engine block apart last night, the previous owner ran it without oil. there was metal shavings all over inside the oil pan. the bearings were GONE. with exception of a few crank shaft bearings. The Cam is pretty much gone. not very useful anymore, so I'm gonna keep the cam gear from it. Crankshaft is pretty much bad too. I put the interior all back together, with new carpet and seats from PAP. Now it smells like junkyard car instead of ciggerette smell, wich is alot better in my opinoin, I can stand sitting in my car now.:brow: Anyway, I'm gonna just take a new moter and drop it into the brat, knowing the condition of everything inside the old engine block, the block it's self probably has a crack someware. I'll have pictures and stuff updated in about an hour on my site. Anyway, later.

It was on there when I got it, but I have done exhausts before, and this doesn't look too tough.

GeneralDisorder is right. start right after the cat. thats where mine starts too. also, if your sate isn't very emissions millitant, bash the stuff out of the cat, it has probabally gone to crap after 20 years.

here is a pic. it might help.

ok, I always thought the idea of dual exhaust was to help the engine breath better, doesn't using the Y pipe kind of defeat the purpose? I always thought having an engine breath better added power, not took it away, then again I don't know a whole lot about how these little flat 4's run. I did rip one apart however.

not when the exhaust you replace it with flows better, most of the restriction in the brats exhaust is in the end muffler, mine doesn't have one anymore!:headbang:

 

if you just want performance and not the dual look also, you can just put a turbo muffler on the end.

 

that will clear up the restriction and add some nice sound, mine roars!

Now that sounds like the way to go, I think I'll talk austin into helping me find a turbo muffler or exhuast for the car, that'll be good enough for me right now.:brow: I'm trying to figure out what all else I can do to get engine "efficiancy" as in, get the most power out of the most gas milliage combination. I'm planning on getting an 1800cc engine block and sticking some 1600cc pistons in it... (did I already say this?) but I'm curious on other ways of doing it as well.

The Y is not your restriction - AKIRA speaks the truth. The Y DOES however balance the left and right cylinder banks for airflow purposes, and this is *nearly* impossible to do without the cross-over in the Y. It can be done, but would cost more than you are willing to pay. You need custom flowed exhaust designed and tested with CAD. Even then, you'll only get BACK what you would have lost with an improperly designed dual system. The Y pipe is one of the biggest innovations in exhaust since the muffler, and should not be tossed out lightly.

Ok, Cool, thanks for the knowledge, learning something new every day. For now I'm not gonna touch the exhaust, later down the road when I have a few bucks to drop into the car I will think about it. For now I'm putting in a standerd 1800cc ea81 engine, with the stock carbrator and emmissions crap. Just to make it drive for a while. the car has 212,000 miles on it, and difinataly was on it's second engine atleast. now it's getting a third moter. Poor thing. I'm worried the engine block that was in it is even dead, cause the cam shaft had no bearings left to speak of, it was running on the bare block. it doesn't look badily scored but who knows what kind of microscopic damage it could have done. My dad claims that the engine block could have small invisible cracks in it, and may be no good, and sense it's aluminum, you can't magniflux it to find out... I don't have much knowledge with these moters obviously, other than how they look torn apart and how the machinics are in them. But what are the chances that block got cracked? it was ran without oil, from the looks of it, several times. Heres a pic of the inside of the engine block, maybe someone can tell me from this picture how bad the damage is, if any... http://www.eskimo.com/~carl/garage/Brat/images/halfblock.jpg

212k? that's it? 2nd engine? Good lord, they must have abused it beyond belief. My parts wagon (that I sold recently) runs awsome at 315k on the original EA81.

 

Can't tell much from that picture. But I have never heard of anyone cracking an EA81 block. I suppose that it's possible, but I've never heard of it. If it's as chewed as you say tho, I would just get a whole new engine, and toss that one in the yard for a bird bath. Sounds terrible.

 

One thing - if the cracks are invisible... what will they do? Personally - if I can't see them, then I don't think they are going to bother the engine either. Get out the calipers and start checking tolerances - that's what we do in the Army.... never had to look for microscopic anything. And there was this one transfer case.... looked like a grenade went off inside - bits and peices everywhere, stuff embedded in the casing.... it was rebuilt. Seemed find afterwards.

yea, poor young brat was difinataly abused, I think the previous owner was lasy or something, there was about 5 or 6 un opened bottles of oil in the bed. he obviously never used them to keep oil in the engines it's self, when we pulled the engine it didn't have much oil in it as well. Difinataly abused the moters... poor thing. Anyway right now, I have a temporarly moter for it, I have no idea what condition the engine is in, but it's fully asembled... and looks fairly clean. I'll find out when we drop it in and start it up.:D

Ok, I lied, I think... I misunderstood austin reading the serial number, he said it MIGHT be the second engine, but I'm betting it's probably the orginal moter for that thing... my bad. so the first moter atleast died by the 212k mile mark, wish is still pretty bad lol. Considering my poor chrysler has about 340k miles on it and it's still running on it's orginal moter... Amazing huh? Anyway I hope tomarrow to be pounding out the front end and putting this little beast all back together again so I can get it road worthy. Check back in for updates on my link.
