Sellers feedback is positive, but there was one comment: "Didn't
realize from listing that these are made to order and take some time"

So looks like you're paying the seller up front, getting the motor
sometime later.

Is Expoxy still the common method for p-port insert?

Tom

In some quarters it is. I prefer the welded variety.
See http://www.rotaryeng.net/fund-of-intake.html

I have been burned a couple of times buying engines mail
order. The best way to buy an engine is either basket case
where you can inspect all the parts or a running engine in a car.

Mazda engines are not hard to assemble. One must be meticulous
when assembling the watch like seals on the rotors but the rest
of it is trivial. I would buy a junk 12A engine and practice.
Some times you can get them for free.

You can also buy engines from established builders with a long
track record such as Mazdatrix. They run every engine they build
on a test stand before they ship it. They will also dyno it for
you for an extra charge. Their engine prices are reasonable.
Perry Mick has over 550 hours on a Mazdatrix engines.

The Mazdatrix price list shows nearly $10K for a P-port engine.  The
difference in pricing is not trivial.

I know, I know, you get what you pay for.

I think they are quoting new factory racing p-port rotor housings.
These are extraordinarily expensive and they will not be p-port
RX8 rotor housings.

They will have 13B peripheral exhaust ports which you don't want.
The trick is to buy an RX8 engine and dis assemble it. New $5800 retail,
$3800 wholesale. Or get a low millage used RX8 engine out of a wreck.
Convert the rotor housings to welded p-ports and ship them
all the parts for reassemble. Let them finish the weld around
the p-port. They did it for me and they do a fine job.
Also ask them if they can bore and weld in the 2 inch SS .049 wall
tubes in the RX8 rotor housings.
