It is hard to find 20B bet you see one pop up now and again.

Question to all experts

• where 20B imported in box to USA?
• where they pulled out of 1990-1995 Eunos Cosmo?
• or other?

Side note
is there any reverse engineering 20B

This information is to help find 20B

 

Eager to see the gurus comment on this thread

 

Yes, starting around 1988, Mazda Motorsports sold non-turbo 20B race engines. The price was $42,000 each. I don't think they still sell complete engines, but they do still sell many of the parts. You can also buy some of the parts from Mazdatrix.

With the exception of the race engines, all of the other 20B engines were pulled out of the JC Cosmo cars.

Custom 3-rotor engines have been made by Hurley and Precision Engineering.

Yashiro Engineering made a custom 4-rotor engine.

There sold on ebay on a regular basis. That's were I bought mine back in May 2003. Ask the seller what series engine it is. If it's a "C-D" buy it. There going for around $4,500.00 shipped!

 

How many different series are there and whats the difference?

The A series fixed an eccentric shaft design flaw. The B and later series had an upgraded center housing. The C and D series had an upgraded eccentric shaft.

 

Thanks for the link and info!

 

I got mine from JDM through EBAY as well.

 

First off Thanks for info to all Thanks Evil Aviator for being there for my first post
