Intro and initial Questions from a newbie...
To start... My home is in Auburn, Nebraska (hanger at Farrington
Field K01) My job (for next 6 months)is in Burlington, Kansas
(hanger at Pamona Lake 39K) In good weather I drive a 350hp 1993
RX7 with single turbo that was setup for me by Rotary Performance
in Garland Texas... I like the rotary a lot.
I currently own/fly a Piper TriPacer 125hp that cruises at 105mph.
(Fun but sloooow)
I just bought a BD-4 project that needs firewall forward (among
other things). In the past I have restored several non-running
projects (1982 Honda GL500 Silverwing, 1993 Mazda RX7, 1982 Yamaha
XJ750 Maxim, 1975 Honda GL1000 Goldwing). The scope and cost of
this airplane project is an order of magnitude greater than
anything I've done previously. It will be a challenge to complete.
Probably several years to go.
Tracy Crook's rotary & psru setup seems like a good starting point
for my BD-4. I would like to add on a turbocharger or supercharger
to develop 225hp at cruise altitude.
I would like to add the IVOPROP In-Flight Adjustable Magnum
Propeller.
My wish list is often bigger than my budget.
...That's my brain dump so far.
Questions...
Anybody got a 13B rotary to BD-4 motor mount laying around to
sell? Maybe just a design?
Anybody got a 1989 13B Turbo 2 laying around to sell? Anybody
got
BD-4 wings laying around to sell? How do we get vacuum for our
gyro instruments? (My TriPacer has venturi for vacuum) Is anybody
close to me? (i.e. southeast Nebraska, northeast Kansas)Â
Last words (for now)...
I am in awe of your pictures, such compact and tight engine bays.
I would welcome all guidance, comments, suggestions, etc.
I have been looking for 1989 13B Turbo 2 with auto tranny on eBay
(because Tracy Crook's comments).
I would welcome offers if you have parts to sell me that would fit
into in my plan.
Best regards,
John Lindinger
John we have developed a motor mount that uses rod ends instead of
welded joints. It will adapt to any firewall bolt patterns.
The pictures show a Tango but a BD4 would be no problem. Some of
the fittings are shown on our web site on the front page if you
scroll down to the bottom. Normally a welded motor mount would cost
1500 and cost hundreds to ship due to the size. This ships cross
country for $60. Cost of the mount not including the adapter plate
less than $500. Contact me for more info.

John: Just a few photos for encouragement. This BD 4C took us 4
years to complete.This aircraft just won the President's Trophy Air
race (our prestige air race) in South-Africa.
Powered by a IO 390 lycoming (210 hp) with a Catto 3 blade prop
just think what it could do with a 250 hp rotary behind the
spinner, probably climb like a "home sick angel"
We have another BD 4 for sale (tri gear version) will be completed
in 2 months.
Could sell it without the FWF ( O-360 and constant speed prop)

John, here is a 13B engine on craigslist here in Miami
http://miami.craigslist.org/brw/pts/3852324730.html. There are
several guys here locally that race these, and I typically dont have
a problem finding engines or parts. There might be a group up there
that races mazdas too.
I recommend searching like I do. I have one completely rebuilt engine
on my plane, and parts for 2 more engines if I need them.
As far as vacuum, some use the factory smog pump plumbed backwards. I
may go this route, but I am more leaning toward what the certified
world calls an electric backup vacuum pump. It is a regular vacuum
pump connected to an electric motor. They go for around $750 or so on
ebay. If you use the stock alternator, it will put out plenty to run
this and more. If you have a small battery it will reduce your backup
time, but unless you are flying in the clouds it shouldnt make a
difference.
My question is relating to the TriPacer- it is a certified aircraft
and the FAA frowns on installing non-certified engines in certified
planes. You could get permission to do it as a test program, but
where you can fly will be quite limited and eventually you will have
to either certify the mazda engine or take it off. I looked into this
with my Bellanca Viking when Continental told me a factory reman of
my IO520D would be upwards of 50K.
Here is the engine you asked for

And another one- this one is factory new
