Installing an EFI engine, or just adding the EFI to a stock n/a 2.3 will be just about the same ammount of work as a t/c-svo turbo swap. The only differences would be in the power, modification of the right front area of the engine bay, and the heater blower motor on non a/c cars. You will need the computer, harness, sensors, fuel pump..... (see the turbo swap thread in this section for more details) you will also run into hood clearence issues too. Because Pinto's never came with EFI, many parts will need to be custom made or modified.
A 2.3 EFI engine can be fitted with the stock 2.3 pinto manifolds and carb (and the other way around), DEPENDING on the engine, it's year, and the dissy. There are some EFI's with an 8 plug head, others with just 4, and some of the 2.3's are dissy-less. Some of the intakes are different, and will need to have a hole or two re-located on the head.
I don't have ALL the details on what parts will directly interchange due to the many variations of parts that are out there, but this thread is here to let others know that there are issues to overcome with this "swap", and I hope to get input from others posted here.
IMHO: If you are going to do this much work, go with the turbo swap and at least have some power for all your efforts.
