Joe,
I did find one of Greedys distributors last week that said
they could / would order it from Japan but he cost was over $800. From
the pictures I found on the internet I could not determine the exact position of
the exhaust exit. I have seen the kit pictures on the several web sites and the
manifold looked different on some. I guess they are showing a generic turbo kit
on some. I sent a email to Greedy yesterday requesting they post or send the
technical manual for the RX8 kit as they have done for the other kits they sell.
This was an effort to get the real picture of the manifold. I am not hopeful I
will get a response. I did find out that the manifold exit curves up. I do not
thank that will work for tractors but it might work for some pusher.
Not sure.
Questions.
1. Would the exhaust exit location out the side close to
center be the most adaptable for most of our applications?
Using bends to route the exhaust up or down and to front or rear of engine.
Something like the example manifold pic I posted yesterday. Will this work with
the CCI and beam mounts?
2. What would provide better sound reduction. A
manifold like the stock unit or one with separate pipes like the
Greddy?
3. Durability.... Stock type of separate pipes like the
Greddy?
4. What is a fair price for a quantity of 5 or 10?
$400-$500 each?
Thanks,
Bobby
Hi Bobby,
I double checked my Renesis and the stock
bolt pattern for the exhaust is definitely not symmetrical. The upper bolt
hole are much further from the centerline than the lower row of bolt
holes. Drilling and tapping a new set of top holes is not possible, a set
of ports (EGR I believe) encroaches on the area that would be needed.
Short answer, does not look like a manifold could be made that is
reversible.
Below is a picture of a manifold Greddy has made
for their turbo kit for the RX-8. They will not sell individual
components nor will they to sell the kit to anyone who does not have an RX-8
automobile. This configuration may work for both pusher and tractor
applications. Also note this is a turbo manifold (runners are kept
separate until they reach the collector.) While this is suited for turbo
applications, it should work in non turbo applications. From the turbo
mounting plate: a turbo (internal wastegate) could be installed, or a exhaust
pipe fabricated to vent overboard, as well as mufflers, etc.

Buly,
I got it now. I am not sure it will work. I ask Bruce T.
once if I could
rotate the stock renesis manifold and his said it would not
line up. I
believe the distance between the ports are different. Bruce has
my
engine now so I will measure when it get back. Or....can someone
else
take the measurement. I do not know how long it will take Bruce
to
finish the mods.

You should be able to reverse (rotate) the manifold end to end,
and
mount it so the single square flange be angled slightly up, or
down.
Don't make me draw you a picture. I won't do it :) Buly
