Why should I get a AEM fuel rail? I mean the injectors still shot out the same. I wanna know what I gain by doing this mod. Also a type r fule pump. Thanks guys!

 

Looks. With large enough injectors, the amout of fuel that can flow through the rail becomes and issue but typically, stock is fine for all but the most powerful engines. Type R fuel pump is the same basic thing. I haven't actually seen any concrete data that supports any of the Integra fuel pumps flowing any better than the factory Civic stuff (my B18C1 ran fine in a '92 CX with a stock pump). It's typically worthwhie to replace/upgrade the pump on a turbo application where the engine is injesting a lot more fuel and could overwealm the pump or if your stock piece is simply old enough to that your worried about it failing.

 

Yeah see that's what I thought. I mean no matter what you change behind the injectors there still shotting out the same amount. Keeping in mind upgrading and not downgrading.

 

I run the AEM rail, but it's because my swap was missing the rail & injectors when I got it. h:

I like to think it gives me at least 10 whp. Don't burst my bubble Andy. :happysad:

 

It also gives you a nice convenient place to put a fuel pressure gauge or if you wanted to upgrade to ss fuel lines for looks.

 

The stock fuel rail can feed almost double than orignally programmed to. After market fuel rails just go beyond feeding your engine more fuel, when neccesary..

 

Yes, the gauge argument is a good one. If you are running an AFPR, it's handy to see what your pressure is at. They can also help you determine if your fuel pump is failing too.

 

Dont you have to upgrade your lines to a larger diameter if you get a higher volume pump? Or can you just use the stock fuel lines?

 

you can typically use the old ones, unless its like a massively higher ammount.
