Does anyone know which parts on a 13b will also work on a 20b?
Rotor housings?
Internal gears?

There is an outfit that was making aluminum end/intermediate does anyone
remember who this is?

Also, does anyone know what an eccentric for a 20b runs for and also, is
anyone making an after market 20b eccentric shaft?

Most parts will work as I understand it. Just the shaft, tension bolts and
one housing are different I think. Maybe the front housing is also different.
 Bruce Turrentine can tell us more.

Racing Beat makes an aluminum back and center housing.

Check the ACRE NL web site for pictures of their 900 HP turbo three rotor
with aluminum end and intermediate housings.

Here is a picture that I don't think is on the web site.
The turbo on this one is not a TO4. It is MUCH BIGGER.

Paul, I think the 20B end housings have the oversize intake ports like my Cosmo
engine. Don't think 13B housings any model are the same as 20B

Yes I think you are right.
