Hello everyone. I have a quick question. I used to own a 95 civic and had fuel rail and injectors replaced with bigger rail and injectors for project civic. But unfortunately it got crashed into and totalled. Now I have a 91 accord with a f22 engine and want to know if the fuel rail and injectors from the civic will work on the accord. The civic had a b16 engine. Will they work as a better fuel economy?

 

That's not how fuel economy works. The engine NEEDS a specific amount of fuel to run properly and not melt the pistons. It would be pointless, possibly even detrimental to swap that stuff over without proper tuning. If the injectors are a newer design with a better spray pattern, it may increase fuel economy and efficiency slightly but again, you would need a tune to see any benefits.
