Hey Gents,

The brat that i have been working on has a EA81 and its a 1981. A friend of mine has a 1979 and i believe that its a EA71. Does anyone know what size motors come in the 79 year models? Does it have to be a EA71? On the owners manuel it has 1600 serise on it. I guess my main question is if my motor went out (EA81) would everything fit so I could put the EA71 in it? Would everything major bolt up?

 

Thanks

all 78-80 Brats came with ea71 (1600 engines) in '81 you could have eather the 1600 (DL, ea71) or 1800 (GL, ea81).

 

in '80 or so they switched the bellhousing over to a "fat case", which alllowed the bellhousings to interchange between the ea71/ea81 I believe...

 

anyways, the '81 GL Brat had a slightly different engine crossmember, but a ea71 should go right in, but I'm not sure your trans would bolt up to it, or if your ea81 bellhousing would fit on the older ea71....

 

but if your ea81 is a good runner, I wouldn't worry about it "going out"

Thanks McBrat,

 

This Brat that I got was given to me by my inlaws. It has been sitting for about 5 years! You would not believe what would come out of a carb, fuel pump, gas tank and fuel line. Its unreal!! I went through the carb saturday and got it to bust off and half way run. (when going through this carb there is a little red ball that is a check valve on the acceleration pump. DONT LOSE IT. lol)

 

The reason i was asking if they were interchangeable is, when i first start it the motor sounds ok, as it starts to warm up and the oil get thinner it starts sounding like its a little wore out. Are all of the flat motors like this? Im gonna change the oil and see if oil that isnt 5 years old helps.

Yeah... 5 year old oil probably doesn't have any lubrication qualities left :-\

 

Does it burn oil?

Not a drop! kinda surprising. Guess these little ol motors are tough!

Does anyone sell skid plates for my Brat? Man the lead off pipes on the exhaust and the oil pan seems like they wouldnt take to much without bustin.

 

should i start another thread for that question?

You mean heavy duty skid plates? Because it should have a stamped steel one stock (unless someone took it off to change the oil, and never got around to putting it back on....)

Maybe so, there isnt anything protecting the lead pipes and oil pan. Theres no tellin, lol

SOunds like it's missing the stock skid plate, because you shouldn't be able to see the oil pan or exhaust pipes going down when you look under there from the front.

I didnt know that. Thanks!!!!! That helps. I know where there are a couple of old brats are and they might have one i can take.

 

Thanks again
