ok i have a 1989 rx7 convertible with a blown N/A engine in it
im getting a 13B Mazda RX7 Single Turbo Engine only 89-91

it comes with
Complete Motor
Complete Head and Block
Intake Manifold
Distributor
Injectors
Fuel Rail
Power Steering Pump
Throttle Body
Exhaust Manifold
Alternator
Turbo

and i am wondering if i will need to get anything else for it to do the swap
will i need to get any kind of wiring harness or ecu .. just anything else i would need.
and will i have to upgrade my exhaust at all? i have an aftermarket exhaust but not sure what kind specifically

thank you again for all your help
