Paul,
        How does the new intake differ from a modified stock lower

intake?  Are

the passages more efficient? Is there more area to mount the upper

intake

runners?

I went down that route. It was a long one:) First I need, (and others

need),

a manifold that sits right down on the top of the engine. It also must

clear

the stock turbo charger. I tried cutting down a stock manifold.
The resulting holes were not round or even oval shaped. Worse they
went off at odd angles. It offended my mechanical and esthetic senses.
I can't be seen with something that looks like a Junk Yard Wars lash up

:)

I considered making a composite manifold at length but finally rejected
the idea as being marginal when it came to heat. It also might not
survive a minor fire. I checked with a pattern maker and he wanted
too much money to make a casting pattern. $5000 at this stage of the
rotary engine market is excessive. So I learned how to make
patterns myself.

Paul,
         I am interested in a manifold but do not need it right a way,

so

if someone needs one put me on the list for the next batch.  I think the
injector holders will be needed also.  Thanks.

As Mike Wills, I and others have done, a stock bottom [6 port] section can yield an
intake that's pretty tight to the rotor housings and quite light, at least
if you are non-turbo.  I've got about 3/4" from intake runners to housings
and it could have been tighter if I need it.   Despite that put me down for
a raw casting and 4 injector holders.  I don't them right way either so I
can wait for the second run as well.

For you guys on LAEV project, all I can say is WOW! I wanna be like you guys
when I grow up.

This works well for the six port as that is what it is.
It has been adapted to the four port by partially filling it
with JB weld. IMHO a bit scary as I don't think the engine
will run well on JB Weld :)

The new RX8 has a similar lower section manifold.

If you use this one it would be safer to move the fuel rail to the
other side of the engine.
