I've been trying to find anything on that subject by doing using the search function of the forum but all I could I find was about Auto to Manual Swap.

So yeah, I'm trying to determine if there's any difference between an engine for an automatic tranmission and an engine for a manual transmission, be it internal or external, the latter would be more important.

As some of you may know, I have a problem with my engine and I intend on swapping it for another one. The thing is, I'm not sure whether I should go with an engine from an automatic car or a manual car.

I tend to think that engines from automatic cars are less abused since you can't mishift and over-revving the engine. I know there may be some cases where even auto can be abused, but I believe manual are more abused since it's reason why one buys one: to race the hell out of it.

My car is a Civic 2004 DX Manual and I'm wondering if an engine from an auto would be a direct fit in my car.
It would be great if it could work without any problem since I'm looking at engines from LeCavalier(in business since 1942) on Ebay and most of the low mileage engine are automatic.

I also heard somewhere here that engine from manual cars have slightly more agressive camshaft, cam lobe?

I forgot to mention that I have already bought one from them, but I discovered that the mileage mentionned were in miles when they told me it was in kilometers.
The engine I bought has 91k miles (148k km) but they told me it was in kilometers. I don't think they were trying to lie to me, their company has just been bought by a bigger company and their computer software has just been upgraded and they told me it was confusing.
So I'm trying to find a engine with lower mileage but I wonder if it's worth it too. Does lower always mean better?
It's a good business, I even have bought the extended warranty of 12 months including labor if something goes wrong with the engine.

What do you guys think?

Any help would be very appreciated.

Thanks

You would have to swap over the flywheel and the pilot bearing. I think the rest would be a direct fit for the most part.


No idea about the cam.


Neglect would probably be worse than abuse IMO.
I wouldn't be scared of a few miles, but would be ideal time to do the timing belt and that stuff while out of the car. Maybe even the head gasket too while it is easy.

Yeah you might be right about that.

But there isn't actually any way we can verify that unless we start up the engine, which the recycler did (the big one that started in 1942). So I guess I have to trust them.

I'm still tempted to cancel the order and choose another low mileage one though. It may be psychological because the engine I got in my car had 164k kilometers when I bought it, which kinda close to 148k. However, I've already test drove an engine with 280k in it and it ran almost like new. So I guess mileage doesn't tell everything especially for Honda's engine. It's more about maintenance.

It's still possible to see the listing on ebay about the car itself, and it looks in pretty good shape, don't know if that could be an indicator of what kind of owner it was or not.

Yeah, I intend on replacing almost all seals and gasket while I'm at it, but I'm still not ready for a head gasket yet, kinda still intimidated of opening the engine in half just like that.

Btw, thanks for replying, I was waiting for some answers but as usual almost nobody answers.

So sad to see a car 3 years newer than mine down for the count.

Ask Ezone to be certain but, I'm pretty sure the cams are the same. The only differences in the cams should be between the VTEC and non-VTEC, which are different heads anyways.

*You have a 2004 DX, right? You need to make sure the new engine has an EGR. The D17A1 only has an EGR from sometime in 2003 to 2005.

Have you tried http://www.car-part.com/

Good point on the cams (VTEC or not). I wasn't gonna look for possible differences between auto and manual cams that late at night though.

The EGR stuff (passages) is all contained within the head, injector manifold and intake manifold areas. If he is swapping the head and manifolds over, then it won't be an issue at all.

Thought:
I have never seen the Canadian versions so I can't be positive about the construction differences (if any), but I would think that all one would need to do is replace the block-off plate with an EGR valve. Seems like the rest of the stuff should already be in place to enable EGR operation. Seems like the manufacturer wouldn't go to the trouble and expense of making a pile of parts (heads, water manifolds, and injector manifolds) that were that much different.
Easier on the production line to drill ALL of them for it, and either use it or disable it (block it off) later on during assembly. That way they can go to either country, be equipped either way, and replacement parts will be consolidated. Right?


Someone up there should check into this idea.

Yes indeed lazlong, my car is a Honda Civic 2004 DX Manual
and yes www.car-part.com is how I discovered about this company.
It's the biggest recycler (in business since 1942)where I live and it has been bought by LKQ, an international leader in car recycling. So yeah I trust them.

I have even seen their warehouse and there are full of engines well placed on shelves.

My car does have EGR and the one I'm buying the engine from is a 2005 LX so I'm pretty sure It has one too. Both cars are Canadian so I don't think there will many differences between these two cars of only 1 year difference.

About the cam, even I, myself, ain't too sure about the info, I heard someone saying on this forum on a Auto to Manual swap I think.

The engine will be delivered on Tuesday (Thanksgiving day on Monday) and if I ever want to choose another one with lower mileage, I'll have to cancel that early in the morning.


Thanks for the responses guys!
