They list a 13G alternator, and that is the only thing that comes up for 13G. When they were available, I'd like to say they were $30k.
20B wise they list a bunch of parts but some of the prices have gone up. They also list parts with a ZR03 and N3H1 prefix. A N3H1 eccentric shaft is over $9000, a ZR03 eccentric shaft is only $5k.
I wonder if the ZR03 parts are 13G.
20B rotor housings are surprisingly inexpensive, I might buy a pair just to have 20B on the engine instead of 13B

the JC Cosmo 20B engine is mostly NF01 part numbers. list price in 2007 was about $15k US, its a new long block, shipping from Japan required
the 13G/20B is ZR01/ZR03 part numbers.
the two engines are completely different and don't share much.
the 13G was used in the race cars, and the competition 3 rotor, 20B was sold over the counter. 450ps@8500rpm
