Hi, Paul.....I received the cast intake manifold.  I tried every way

I

could to make the gasket

line up with the holes, and found that the bottom two holes would be

off

the end of the flange.

Then I noted the e-mail from John Slade, stating that he had the

same

problem. You replied that

you "screwed up slightly on that version when you tried to save

weight,

and that you will add a

little more metal to the flange on the next batch".  Fortunately, I

am

not in a hurry for a good

fitting manifold.  I would much rather return this version and wait

for

the next batch, as I have

no welding and machining skills nor contacts. I was hoping for a

version

like the first batch, or

the next batch.  Thanks, Paul       Paul Conner, Mobile, AL

This manifold and the next batch will not fit the third gen engines
without
extensive modifications. If you cannot make these modifications send

me

private
email and I will give you shipping instructions to get your money

back.

We have no plans to cast a manifold specifically for the third gen

engine

at this time.

If you have a third gen engine and you are thinking of ordering the
manifold don't!

Well Paul,
I remember you saying that you made them to fit the 93s as well, and
that is why I ordered one myself! I have not had time to fit it yet, as
I am still moving. Exactly WHAT modifications are required-drawing
please?

Marc Wiese

I am not sure. I don't have a 93 engine. The ports are a lot larger
and the mounting bolts are in a different location. Extensive modifications
are required. However IMHO it is much easier than starting from scratch. If 
you don't have access to somebody with a tig welder I would not try it. In 
the modification process you could:

A. Over do it on the wall thickness and break through.

B: Need some material that is not there and will have to be  
built up slightly.

I'll be glad to give you your money back. Frankly I assumed anybody
considering a rotary engine in their home built aircraft would have
access to a welder. I really don't think the rotary engine is a bolt in operation
quite yet. As a minimum you will have to weld runners to the raw manifold
casting. 

Sorry if anybody got the impression the manifold was ready 
to bolt in and run. It is merely part of the raw material that you will
need. To make a complete NA manifold you will need the lower manifold casting,
four 90 degree bends in tubing or pipe, some sort of injector holder/bell mouth,
a plenum chamber and a throttle body. If you are building a turbo setup
you will need a lot more none of which is available off the shelf.

We are working on stocking the 90 degree bends required and we have
the injector holder/bell mouths available. Think of this as incomplete kit
of parts. We do not intend offering a plenum in the near future as casting
it would make it too heavy. Same goes for the throttle body as there
are many in the junkyard that can be used. They must of course be 
attached to the plenum.

The 93 and 95 engines are too rare to support with a dedicated casting.
I think only about 500 95 RX7's were sold in the US. I know
only 500 RX7's were made and sold in the last year of manufacture.

Since at least 18,000 RX8 motors will be imported into the US next year
we will do a new lower manifold for the RX8 motor.
