The slide throttle bracket is in. Will work with a 3 rotor.

It will be part of the slide throttle kit as soon as we get the two missing
parts that are still in the NC shop.

If you want one for a 3 rotor slide send $15 + $5 cash only for a flat rate
box. No checks.

We are also nearly out of pressure taps for Tracy's EFI that screw into the
oil injector port. How many are interested in this part as I will have to
make more?

Paul,
I was going to order the pressure taps and the sliding throttle assembly
together, so you can put two hash marks on the wall for me.  Just to make
certain I am not off base here, my engine will be a two rotor 13B, with
compound turbo, as soon as you start cranking those out. . .

Thanks,
Gordon

Well as much as I would like to do that I don't have the resources.
My guess it will take a really big company to do that.
Hopefully Mazda will see the light

Paul Lamar

Paul,

Are the pressure taps designed to work with a standard (NA) 13b, or just the
PP installations? If they will work with my 13b, I'll take a pair.

Thanks,

Jack Hilditch

They will work with the side port engine but if you have a large plenum like
Tracy's uses you may not need them. They are mainly designed to work with
tuned intake systems that have a lot of pressure variations.

I've got the Mistral system (see attached).

Jack Hilditch

Lucky you :)
Do you have the Mistral computer or Tracy's computer?
If Tracy's you could probably use the pressure taps.
You will get a smother MAP signal.

Jack Hilditch, nice intake-are mistral parts available to the average
JOE?-james whitehurst

James,

I'm not sure whether Mistral parts are currently available.  These had already
been purchased for the engine when I bought it.  Since Mistral began focusing on
getting an engine certified, they may have changed their attitude about selling
parts to the general public.  It certainly wouldn't hurt to ask them.

Jack Hilditch

IMHO I might add that this intake manifold only fits the late model
2nd gen 13B four port turbo engines as far as I know. Most 2nd gen 13B
engines are six port. I also don't think it fits the third gen 13B
four port dual turbo engines.  What engine do you have Jack?

Paul Lamar

Paul,

I'm not exactly sure which engine this is. That prompted my earlier post asking
how to positively identify the engines without knowing which vehicle it came
from.  I tracked down the original project builder and found that he bought a
short block built by Bruce Turrentine at some point. He said this appeared to be
the engine he purchased but that was all the information I could get from him.

My intention is to open the engine up and do a thorough inspection before any
test runs. I've reached inside the exhaust ports and can depress the apex seals
with my finger so the periodic preservative oil spritzes and my turning it over
manually seem to be keeping it in reasonably good nick.  At the moment, however,
I am in drill, deburr, dimple and rivet central as I work on the fuselage.

Looking at this jpg I can just see the blocked off heat riser on the center
housing. That probably means it is a 2nd gen turbo engine around 1988 to 1991.
Unless somebody has put high compression rotors in it it
has a lower compression ratio than the NA engine. Not a show stopper but
it means a bit more fuel burn and slightly less HP.
