A streetported and injected 13B will net 200 HP or better. There are many
incarnations of them, from the early four ports to the late 6 port variable
port timing ones. Some are better than others. As the EFI adds some mileage
to the engine, the porting quickly takes that away.

The 20B are the Cosmo engines, and all were twin turboed. Pete Farrell has
modified one of these beasts and installed it into a customer's 3rd gen RX7
with a Electromotive EFI and got something over 500 HP.
