Larry,
I have a Cozy MKIV with a 1990 13B turbo.  I bought a JDM engine, =
stripped it down, built the intake and other peripherals, and flew it =
that way for about 10 hours.  I then removed the engine and rebuilt it.  =
If I was doing it over, I'd just rebuild it up front.  I did mine =
myself, and also with Tray's book and Bruce's video.  It was pretty =
easy, and I don't consider my mechanical ability as a particular strong =
point.

If you do the mild street porting, you should easily get 180+ HP.  I =
went the turbo route, and it does come with more weight, and more heat =
to dissipate.

If you want any photos, I would be happy to provide you with as many as =
you want.

John Slade is another Cozy builder with a 13B, also turbo.  I haven't =
looked at his web site in a few years, but it has been very good.  John =
took the time to document his project, in great detail.  I just built =
mine, and while I kept a log, and took lots of photos, that was about =
it.

The 13B route is not for someone who doesn't like the experimental side =
of flying.  There have been two other Cozy builders that after flying =
for a few hours have elected to change them out to the Lycoming. =20
As for me, I am very happy with my decision to go with the rotary.   =
But, I also enjoy tinkering with it.

Regards,
Steve Brooks
Cozy MKIV N75CZ

Subject: [FlyRotary] 13b engine

Hello,

I am currently building a Cozy MK IV and I am planning to rebuild a 1986 =
Mazda Rotary 13b. I have purchased Tracy Crook's Book and Bruce =
Turrentine CD and both book and CD have a lot of good information. =
However, there is still a lot I need to learn which are not discussed in =
these materials.  In general, I am thinking I will do a street port in =
order to get the engine to 180 hp. My Question is does anyone have this =
configuration in a Cozy and am I on the right track?

Note: I have purchased new Rotor Housings and other parts, so my =
investment is growing.  I thinking I could sell the engine if this is =
not a good Idea. Also, I could use suggestions as to where to get more =
information on installation of this engine in an aircraft.

Thank you in advance.

Larry Rasmussen
