HI PAUL

I DISMANTLE THE ENGINE AND AS PER THE SELLER THIS ENGINE
SHOULD HAVE ABOUT 30,000 MILLES AND LOOK NICE AND CLEAN

I DO HAVE SEVERAL QUESTIONS FOR CONVERTION

I WOULD LIKE TO KNOW IF WE CAN USE THE SIDE PORT AND THE
P PORT TOGETHER AS A 6 PORTS AND WHAT I CAN GAIN

WHAT IS THE BEST LOCATION TO INSTALL THE INJECTORS IF I
USE THE MECHANIC ONES OR ELECTRONIC INJECTORS

DO YOU KNOW ANYBODY WHO INSTALL A MECHANIC FUEL PUMP BY
USING ANY DRIVE OR AS OIL INJECTORS DRIVE SHAFT OR IF YOU HAVE ANY
SUGGESTIONS.

THE RX8 HAVE 2 INJECTORS ON INTAKES AND 2 IN THE MIDDLE
SECTIONS DO YOU THINK I CAN USE THE SAME LOCATION IF I GO WITH
MECHANICAL INJECTORS.

YOU MENTION THE LAST E-MAIL YOU DO HAVE A NEIGHTBOR WHO
CAN MACHINE THE SECTION FOR THE P PORT AND DO YOU THINK
THE SAME MEN CAN INSTALL THE PORT AND TIG WELDED IF SO HOW MUCH

THANK,S FOR YOUR ASSISTANCE

Using both does not seem to help. Richard Sohn tried that.

The position of the injectors does not matter much. There is
a little data that indicates slightly lower fuel burn if the
injection is done at the start of the runners.

I don't really have a reliable tig welder that I work with in
California.
Scott from Iron Designs might be interested.
Scott are you interested in making some p-port manifolds

We can bore the holes in the rotor housings however.
The rest is even easier to do and can be done by anyone.
Send us the rotor housings and we will charge $150 plus
the cost of shipping them back.

I don't mind doing any type of tig welding.. as long as I know what
the base materials are. And what is expected to be welded. I might as
well say it right up front.. I will do anything that needs this kind
of delicate work and we feel we are pretty good at it. But below is
what I have stopped doing.

1) I don't take parts with poor plans and then try to fit pieces
together. ( I generally find several others have tried to do the same
thing and everyone keeps a part or two)

2) I don't prototype unknown working parts for free--if it was
easy, anyone can do it.. And some thinks "this anyone" likes to do
something for nothing. Been there, done that.

Which rolls into this:

3) If I say it will cost $10 then it will be $10.... If I say it
will be $54 then again it will be that. But it will almost never be,
"take it, see how it works and pay me later"... Unless it is
something I feel is heading down a great path for standardization in
the Rotary world, I don't really want to experiment on my pocket book
for someone else's gain. I am a firm believer that any designer
should fly in his own design aircraft or behind his designed
motor..and do it often.

4) our shop rates are honest and fair--nothing extravagant- If say it
will take 2 hours, then that is what will get billed for. If it takes
3, that is my problem. But I hold the right to say, this needs a
review after the first one. This goes both ways. If it takes less,
you will know it.

Hope this helps.

Scott

This is what he will need Scott.
I have stp files on all of this that will load into Solid
Works.
Plus read all this. http://www.rotaryeng.net/intake.html

Yes this company has built mechanical fuel injection for
rotary engines.

This company builds mechanical fuel injection for racing.

Paul it should be mentioned that the oil injector drive isn't
big enough to run a mechanical fuel injection pump.
Heck it is barely big enough to run the oil injector pump! That
isn't intended as a criticism, only that the oil pump needs only
pump about 1/100th of the volume needed by a fuel injector pump.
Most mechanicals run a toothed belt from the crank. Some of the
sprint cars have a special front cover and drive from the cam
drive.
