Remember these are not final. You will have to do further work on
them. Also double check all dimensions.

Once unzipped they should import into Solid Works.

Thanks, Paul.  What shall I tell him for material?

6061 T6 is fine.

Hi Paul.  My friend called me yesterday to talk about the end
housing.  He proposed that maybe the easiest way for him to price the
end housing was to just make one.  I told him to hold off, given that
it wasn’t a finished part, but looking at it, I don’t know what I
need to do to finish it.  I looked for dimensions to check, but not
knowing what they should be, I can’t really be of any help there
either.

Have you gotten yours any further?  I don’t mind working on it, but
I’m feeling a bit useless in that department since you don’t want the
guy with zero experience designing the parts.  I think I’m more
useful if I spend my time pricing materials and doing groundwork.
Any chance you might be able to come up with a finished design that
he can just go ahead and make?

I realize that all of this stuff distracts you from getting your
turbo compound running.  :)

I am over loaded right at the moment.
The best thing to do is get your self a junk front end housing.
You will then see what needs to be done.

Here is one on ebay for $34. Take it to a machine shop and slice it down
the vertical centre  with a big band saw.
After you examine you will have some questions. Don't hesitate
to ask and I will make some suggestions.

I was put off by the $55 shipping price to my location.  I did, however, spend a couple of hours last night going over the models and emails.  I think I’m a little bit more caught up now.

It looks to me like what’s needed is:

- a groove for the o-ring between the steel plate and the end housing.
- some sort of threaded hardpoints for mounting the water pump
- some arrangement for mounting the output hose, although I guess it could just be threaded for a pipe.
- maybe a better water pump arrangement, so that it won’t be a continuous issue.  I’ll ask my friend how much difference in cost leaving an ear on it for the water pump would make.  I realize it’s a waste of metal, but maybe it’s worth it.

Is that about right?  Did I miss anything?

I looked through a couple of dozen different water pumps today, looking for one that might exit toward the rear with a complete pipe that wouldn’t be constantly leaking.  No luck yet.

I also realized last night that the IGES file isn’t quite importing into SolidWorks.  I’ll mess with it some more when I get the chance.

Where was it Dave? Where are you. Mazdatrix here in SoCal has some used end housings.
These jpgs might help.

I'll send an iges on a water pump housing Tomorrow. It needs work
to get the bolts in the exactly  right place.
