Well it depends on what you future plans for your car are. If you are planning on adding a turbo or a supercharger then I it would be a good investment. If you are planning keeping it basic with just I/H/E it would just be a waste.

Can you explain why??....I've seen set ups w/out turbos that have the fuel rail.....just curious.....thanks
As far as I can tell the rail is 1/2" wide internally. I need to measure but I think it's the same as stock....just makes adding a fuel pressure sensor or wetshot of NOS easier with the extra ports.

Aftermarket fuel rails are larger than stock and allow you flow more fuel to your fuel injectors because of the larger internal diameter (as long as your fuel pump can supply the extra fuel). This larger bore also dampens the back pulse created (if you are cruising along and then punch the gas pedal) by oversized injectors in high-output applications. On a stock engine, most people do it for show but some people claim it will dampen the back pulse and the engine has more 'punch'.
It is also easier to add a fuel pres. gague or N2O, like lazer stated.

So far these reasons are favorable to any set up.....right??...a guy that was training in the building next door has one on his stock Si, one thing he said about it was that for some reason he had to warm up his ride : ....not sure why....another question... with more delivery of fuel...does your gas milage suffer???....( I don't like to sound dumb but since we got into this subject, another thought creept into my demented mind )...thanks
yeah the fuel rail is a joke, it is worthless unless you have a big hp motor. Otherwise it is a waste of money. You might as well take the money and go buy fuel pressure regulator and pump up your psi a couple, that will have more effect than the fuel rail.
