I recently bought a EA81 long block to build for a rail buggy and I am looking forward to learning more about this powerful little engine.

Here are some pics. This is before I cleaned the area up. I have started cleaning parts and I have to order a manual to be able to measure all the components. I think I should probably start a new thread for the build to match the title.

Just a quick late night update. As suggested I soaked the wrist pin plugs for a couple of days wth sea foam penetrating fluid and was able to get 3 of the 4 pin out. I split the case and I am in the process of getting the 4th pin out. Letting it soak overnight. I will clean up and post pics tomorrow.

Well, I got a little further today and a couple questions came up. Overall I am pleased with what I saw today. With the exception of a couple stripped bolts on the exhaust manifolds things look good. The cylinders don't show any pitting which make me positive about the cam condition. I was thinking about taking the heads to the machine shop, but I better make sure the host block is buildable before sink any money into the heads. I have no idea what a ready set of heads are worth should I get stuck wish them. Anyway, can one kind guru help a newbie with these questions? 1. How do I get the oil pick up tube out? I tried everything I could think of. 2. Can anyone tell me what distributor this is?

Thanks for the tip. When I get that far I will give it a try.

I know what you mean. I am really hoping the inside looks good and just a few new parts will do the trick. Later, I am going to post a picture of the distributor and see if one of you can identify its brand.

So it begins. Got it on the stand and started taking parts off today.

Interesting build. Love the trike. I am thinking 32/36 carbs would do me just great. Where did you get most of your parts? I checked out Ram Engines and they have some parts listed, but I am wondering if they have more than listed on the web site.

Thanks for clarification on the different manifolds. I am not trying to go over 100hp. Really a stock build would be fine, but I would like to get a few more HP out of it. So far I am just thinking Webber carb, new cam and since its a buggy high flow exhaust should help get a couple HP's.

I have a EA1 engine that I obtained. It did not come with an intake manifold. I would like to acquire one and test the motor before opening it for a rebuild. I have been reading about the differences in the EA81 and EA82 manifolds. From what I read I think I should get a EA82 intake manifold due to better air flow and it should fit? Can someone provide feedback whether this is correct? I plan to use this motor on a rail buggy I am beginning to build. Also, I have been using RockAuto for parts list, but is there a good aftermarket performance website? Thanks for the help.

Hello Forum, I am totally new to Subaru. I was looking for a new motor for a rail buggy I was thinking about building. I didn't want to go with the normal VW motor and the more I read about the EA engines the more I liked them. I have purchased a EA81 engine and I am now educating myself before I start spending time and money getting it ready. Once I get started I plant to post pics and topics related to the build. Glad to be in the forum.
