Check out my new ride 1978 Cosmo
 

I bought this off the second owner, always garaged and it's a Cali car. All original. But it's smoking, what a shame, time to rebuild. Debating whether to convert to 5 speed or leave automatic. Very beautiful paint, almost mint interior. Check it out. opinions are welcomed.....

Yea very nice and I think you should keep her auto just to keep it original. I love those weld wheels on your SA....nice look.

:werd:

+1, keep it stock!

Looks like I got to carb to work, I took the top part off and cleaned it on the spot. It was all gunky. I have another Cosmo engine laying around, I guess I can do a swap and pray for the best. Will keep you guys posted.

I decided to rebuild the stock engine, I just ordered the engine rebuild kit from Atkins Rotary. It's enroute to my house as we speak. We will see how it turns out.

Nice! There's always been a warm place in my heart for the "black sheep" of the Mazda family! :)

do me a favor and send that motor my way :)

Hey Jerry some BIG brown truck just picked up your parts so you should be seeing them in about a week... Also if you want a tracking # just let me know...

BTW Nice find on the 78 Cosmo..

Later

Danny,

U DA MAN! Thanks!!!!!!!!

I have 4 old school 13B 4 ports and one GSLSE engine. I can't get rid of any of them, they are hard to get but I have a friend in Conn. that has a 74-75 Big Script MAZDA old school 13B 4 port he is willing to sell and it's cracked open ready for your inspection. It is beautiful. If you are interested I will PM you his number.

Nice Cosmo! Register it on my guest book so I can try and keep track of the ones we keep alive ! Thanks Brian www.mazdacosmo.com

Slick!

It's funny. The rotary engine doesn't necessarily always have to go into a sports car. The rotary is so smooth that it lends itself well to a luxury car as well. The Cosmo just needed more power. I think that's what hurt sales here. They loved it in Japan.

Too bad politics killed the 15A because I'm pretty sure the Cosmo chassis was designed to include the 15A as well as the 13B, 12A and 1800cc boinger in its engine portfolio.

Knowing that, the hard part is figuring out how to fit a 20B in there. :p:

Found a racing beat header and rb muffler, it's getting closer and closer....

You learn something every day. I never knew there was a 15a on the plans...

go figure

The 15A was scheduled to come out in '74 or some time later. The 13B came out in '73 and was in two 1974 model year vehicles: the RX-4 and REPU.

There are several tranny mount holes on the underside of the Cosmo. It's my guess one set was to be used with the 15A.

Keep it stock with the engine!?!?!?

Jerry - If you decide to put a manual in it let me know. I would happy to give you a hand. Kinda been there and done that.

Any idea why it never came to be?

Rumor was sometime ago, that the "new 7" would have a 16b right?

wow thats very clean

Engine is out of the car, never realized how big can a starter be from a Mazda. This thing was huge and I probably pulled a muscle because of the awkward angle. I made my mind and it's getting converted to manual.

Great looking Cosmo. I hope to see some vids of it sometime, or at least more pics.

I have been procrastinating a little. Trying to spend quality time with frie4nds and family. Well, yesterday I decided to crack open the 13B 4 port Rotary Engineering engine. It looks good. Rotor bearing are questionable. Here are some pics.
