I was reading in the Turbo/FI section about getting rid of the returnless fuel system... would that help out an a NA car?

 

yes it would but there is a lot of work involved in doing a return fuel line - surge tank, lines... fuel pressure regulator.... it can be done and would be very handy thing as the car would not lean out in the lower rpm and that you have greater control over your mods as well but it mightbe just as easy to have a 5th injector I suppose it depends on how far you want to go with mods

 

It doesn't seem to be that much work... evo fuel rail, es filter assembly, fpr (which would now be located on the fuel rail) and of course running lines... coming from a *cough* honda background, adjustable fuel pressure regulators are a big deal... of course you don't get the kind of fuel control that you will with a new ems but it could help if your running lean.... at least enough to get you out of the red...
