Carbs or Fuel Injection?

[Alexandre]

Hello everyone,

I am changing my engine to a 502 but i don't know if it's better to take a carb or a MPI system?
You can see below the spec of the carb engine i would like to put.
Do you think it will be too powerfull for my 1988 Donzi 22 classic? Will it feet without any change of the hull inside the Donzi 22C?

Do you think it's better to find a 502 with a MPI system?

Once I learned to work on fuel injection, I was amazed that anyone continued to mess with carbs.

I'm sure some people have reasons that they like carbs better...

Worked with them all, its your choice. Most find carbs easier to build and hop up, but good guys can do either but it always cost more for EFI. ECUs can be a real pain unless you go with an aftermarket type my preference is Motortron.
