20 b rotor housing
Can someone tell me if there is a difference between the 20b rotor housing and the 13b rotor housing.Need to know if i can use it in a rebuild.Someone said to me that the 20b housing was stronger,find that hard to believe.

If the 20b housings are within spec, wouldn't it be cheaper and easier to just switch out the 20b sleeves with the 13b ones? I know someones done this before.

Since we're on the subject I have a question about fabbing up a 20B from 13B parts.
Is it practical to create a tripple rotor engine from two 13Bs and just have to find the eccentric shaft and intake and exhaust manifolds?

There is a a shop in New Zealand that produces shafts and will modify a 13B intermediate housing with the extra stationary gear and bearing. However, when you do that, the 20B manifolds will no longer fit as the custom engine is shorter than the 20B and has smaller intake runners on that housing. From memory, the shaft is about $1200USD and about $300 to modifiy your supplied housing.
