    EA81 engine mount drawings

    I am wondering if anyone has drawings or plans for an EA81 engine mount? I have seen pictures, but no data to go with them. This would be for a Zenith CH750. Any help would be appreciated, thank you.

    Quiting aviation

    So I just got my PPL, in fact at the moment I still only have the paper copy of my PPL and not the permanent one. For several months before taking my exam, I was debating on weather it was worth getting my license or not. Instructors that just dropped me, another instructor that said that he...

    EJ 22 in Zenith 750 STOL

    I have not looked at the Subaru 6 cylinders, I have heard that they are like the EJ's with two extra cylinders. If that is the case, then they will weight too much for my application as the EJ22, from what I understand, will come in at close to 300 pounds and the max engine weight is 300...

    EJ 22 in Zenith 750 STOL

    Yes, I think 200hp might be a bit much, but if I get it dyno'd then I would know what RPM 130hp is at and use that as my max RPM. My thought is that since I live at kinda a high density altitude, that if I have a little extra horsepower that it would help with the density altitude. Maybe that...

    EJ 22 in Zenith 750 STOL

    So I am thinking that if I build it to around 200hp, I will not run it at that horsepower, but it will give me a little extra power at my density altitude. I do not want to hot rod the engine either. I will rebuild the whole engine and plan to go with a different cam anyhow. I have read that...

    EJ 22 in Zenith 750 STOL

    rv6ejguy, I am just wondering if I stroke the EJ22 to get around 200hp instead of using a turbo, would that cause an issue? I would try and have it dyno'd, so that I know where the 130hp rpm speed is, so that I can set that as my high idle, but the extra horsepower might be able to take the...

    EJ 22 in Zenith 750 STOL

    So what is a realistic weight I can expect with an install. I will use as light of an alternator as possible as I am using LED's on the plane and will not have a glass panel, so power usage will be pretty minimum. The motor I have now comes in at 205 pounds with out the radiator, alternator...

    EJ 22 in Zenith 750 STOL

    Some very valid points. As far as valve cooling, I would think that a liquid cooled engine would be better at cooling, thus even if it produced more heat it would have the coolant to help dissipate the extra heat. I like the idea of a more modern engine, fuel injection and electronic ignition...

    EJ 22 in Zenith 750 STOL

    Thank you, one more piece of the puzzle solved. Not many pictures of EJ's installed, and the few that I have found are not very good at showing the motor mounts.

    EJ 22 in Zenith 750 STOL

    I know this is the Subaru form, but any ideas are good, maybe it is something I had not thought about. If the Subaru looks to be too heavy for the Zenith then I will look at other options, and may end up with a Corvair, as C51 mentioned there are several now it the 750's. Are the EJ 22's bed...

    EJ 22 in Zenith 750 STOL

    The Zenith is designed for a 300 pound engine weight, so it will take a Sube. The engine should be about 120 hp, but I am looking to have it dyno'ed, that way I will know what my max rpm will be and can run at a lower rpm to achieve the 120 hp, which will help with engine wear. I have looked...

    EJ 22 in Zenith 750 STOL

    Thank you all for your comments and concerns. Price is a major factor, I will look at a mid time 0-200/0-320. From everything I have seen even these engines are a little pricey. I am putting extra tanks in my wings, the thought being that I do not want to use 100LL, so if I take a long trip I...

    EJ 22 in Zenith 750 STOL

    I am currently building a Zenith 750 STOL and am looking at engines. I understand that a certified engine would work well, but am leaning towards an EJ 22. If I go this route I will go with the SDS wiring harness for ease of application and tuning, also looking at a Garrett turbo but have not...
