How difficult is it to swap a 13B turbo/Twin turbo into a 83' RX-7. This is my first rotary I've ever owned I'm used to tuning fuel injected cars and would much have the turbo 13b engine over the 12a just need to know what the swap involves. I want to attempt to do this swap myself but need to know exactly what is involved, considering that the engine has an ECU and is fuel injected instead of the basic carburated N/A engine. Any help or links to documents about the swap would be greatly appreciated.

 

there are lots of people who have done the 13B turbo swap... twin turbo swap, i don't know if anyone has or not, but the single turbo setup ala 87-91 Turbo II is very popular... try a search eh
