what is the diference between the two engines?
Anyways the difference is the exhaust manifolds have bigger ports and I think it has a 20B throttle body.Here check out this link you can really tell the difference.

Also the RE Cosmo rotor housing are coated in a different material.

1) Cosmo 13B has SMALLER exhaust ports, but the same rotor housing. Only real difference is the sleeve.
2) Cosmo 13B has BIGGER intake ports.
3) Cosmo 13B has BIGGER primary port runners on the upper intake/lower intake manifold
4) Cosmo 13B has SMALLER throttle body.
The exhaust manifold is almost identical, but the cosmo 13B has smaller compressor wheels/housings.
