I'm really starting to sway toward the ea81, the ea71 I have is far from worn out, she's just a baby. but I'm sure my hatch would greatly appreciate the ea81. I know I'd appreciate not getting my a$$ handed to me by a chevy sprint (geo metro).
I had my @$$ ridden by a 1986 chevy sprint the first night I got this car. I burried my speedo at a whopping 85mph, lol. he overtook me, and I tried to keep up, but I gave in. I'm mean to my cars, but not that mean.
so now that I'm gonna go with the ea81, do any of y'all know where an oregonian can find the block, heads, good cam. and do we have a price list?
-
hmm, lets see, timing belt every 60K with ej22, or timing belt every 20 billion miles with ea71... thats a hard choice to make... oh wait, its not!
-
well we can slice it like this, the ea82 was what, a 90hp engine? aint the ea81 & ea82's 1.8L motors?
ok, so the saying goes "There's no replacement, for displacement" it works for cars as well as guns.
so theoretically speaking... you can shave the heads, grind the valves, port and polish the heads, put a custom cam in it, and if one were so inclined, one could stroke the crank. is this possible in subaru engines? according to ccr, boring the cylinders is not an option due to heat dissipation issues.
I looked at ccr's website, to me, (judging by the picture) the ea81 looks like a ea71 with the starter located off to the side a bit, im sure the insides are differnt, but the outside looks quite similar.
-
you said you wanted to see a 110hp ea81, lol

I do have the top mount starter version of the EA71. its a very young car compared to the other subies I've had, I got this car with 113,xxx original miles, I'm the 3rd owner, I have all of the maintenance and tire records, it even had the tires on it from 1989 when I got it. she now has 137,xxx on it. I've added an overflow reservoir from a 93 legacy.
I've only had a few minor issues with her.
clutch, v-belt, distributor bearings were gettin dry so I replaced it, and my fan control switch just went out. I did a quick fix and grounded the wire so the fan comes on with the key. I got her august, 2008, she has yet to break down on me.
my reasons for not going with a different motor have nothing to do with my mechanic abilities. my theory is "If I'm going to increase the hp to that of an EJ22, I might as well get a better platform, drop in a EJ20TT, upgrade the suspension, get urethane bushings, coilovers, racing clutch, air fuel controller, turbo timer, etc..."
I might as well buy a fully modded sti. or drop in a chev 350.
a lot of you might think I'm trying to polish a turd. and maybe I am, but this car is worth it in my eyes.
I'm shooting for a 25-35hp increase. if I have to build an EA81, I will, but that's as new as I'll go. I don't want any turbo, or nitrous cheater power. I want actual power.
so new questions, what can be done to an EA81? how much power am I looking at?
-
I was just trying to clear up the rumors I've heard.
I'm not trying to get a million horsepower. I'm trying to get something more than what I have, I'm really tired of the EJ22's, granted they have a bit of stock power, but they are worthless, problematic, and high maintenance.
I have had my fair share of EJ22's. so far I've had a water pump explode, timing belt jump 2 teeth and run like garbage. and my personal favorite... I had one throw a rod through the top of the block at less than 120K. engine was full of oil, clean oil, no knocking, rattling, or pinging until it happened.
I just cant kill this EA71. I've blown head gaskets on 2 spfi EA82's.
so lets restart this whole thread...
I am sticking with my EA71, I CANNOT PUT EA81/82 HEADS ON IT.
I CAN have delta regrind my cam.
I can use EA63 Heads if I can find them.
I can buy a weber.
I have used NGK Iridium Plugs w/premium gasoline w/octane booster,
just the NGK's made a night and day difference.
Premium Fuel makes a noticeable difference.
I bought a distributor from a guy on here, he claimed it was for my motor, the plugs were the same, now It wont time to factory specs or run decent without idling @ 1700rpm-2000rpm... speaking of which, it says unhook and plug the vacuum advance hose... WHICH ONE?
-
OHC means Over Head Cam, right? wouldn't that mean the cam is in the top of the head? but I dont have OHC I Have OHV right? since my timing chain is on the tranmission side of the motor, not a belt in the front like ea82 and ej motors. am I correct so far?
Don't get me wrong, im not debating whether or not the heads will fit.
I've heard 2 distinct rumors (I say rumors, because I don't have proof yet)
rumor #1. (came from a member of this forum) "you put Ea82 heads on an Ea71 for a 150hp increase" "It's a trick that nobody knows about, I can't tell you, cuz I don't know you well enough"
rumor #2. (came from a google search) use of high flow air craft heads on an Ea71 will increase the hp... not to 150, but definitely a substantial increase.
I've had 3 Ea82's and only 1 Ea71, I have never tore them apart, but I have removes the Ea82's from the vehicles, and know they look a lot different from the Ea71.

I have a 1980 1600 4spd 4wd hatch. I plan on buying and installing, stripping, and refinishing the car this summer. I really want to do some internal engine work.
I plan on replacing the stock hitachi carb with a webber, I am looking for opinions of head, cam, piston, rod, and etc... configurations to get more tq, and hp, while still maintaining somewhat of a decent fuel mileage. maybe 12+mpg
from what I've heard, I could use ea82 heads, port and polish them, and get more hp, but I'm not sure if I'm only being told part of the story. can anyone give me some insight into the realm of ea engine building?
what resources and options can you give me?
what cams are available?
I'd like to have a really rough idle. none of that smooth garbage. I wanna feel the car.
I'd like to change the weight to hp ratio from 30+/- lbs per hp to something in the 20+/- lbs per hp. maybe not so extreme but something in the neighborhood, if its achievable.
Thank you all, look forward to hearing from you all.

beautiful! you are very dedicated, and very inspiring. Good Work!

The front bolts are on the struts. You'll see 2 bolts at the bottom of each strut. Tighten them up and it will lift the front end.
Yes, mine has a 3rd eye headlight on it.
(this is an old photo of it)
thank you for the bolt location. I probably would have never found it, it doesn't even look like it would be used for adjustment. I'm gonna go try it out right now.

well I'm the only person I know who has such fondness for Subaru's.
I'd love to do something with my 1980, but It's currently my daily driver.
-
I am so jealous of you! I have a 1980 1600 hatch that I got for free, and a 1990 legacy sitting and waiting for something to be done with it, all I'm waiting on is money and time to do the ej22 swap.
how long did it take you? and how much of a P.I.T.A. was it?
haha, I'll trade my legacy and 1600 for your finished project, lol.
oh, how fast does it go? and does it still perform as good with the awd trans?

Ea71 mod advice... HELP!!!

not afraid of t-belts a bit. I'd just rather have something a bit more solid, I know we are dealing with non-interference engines, so im not worried about that, I just don't like the ej22, you aren't gonna be able to change my mind.
ram engines sent me a reply, they have an ea71 for $850 with "88hp and 95 lbs. torque. These hp figures are with different carb, headers and the distributor curved."
so you guys are telling me its basically impossible to do. and ram engines did it. they also say they can give me more hp if I want different internals.
I checked my local wrecking yard, and they have several ea81's and ea82's plus a plethora of 5spd dual range 4wd trannys. so they aren't really that hard to come by.
