ive got a chance to buy a cheap aem fuel rail for my b16a sir, ive got a BMA induction kit and a 4 branch manifold.

will the rail make any differnce?
what do they do?

 

You should get it... well you should run a search up at the top and type in "fuel rail" or look it up in the Product Review section for your car... I dont know anything about that kind of stuff, but I hear alot about the things they say on this...

You should also wait for someone with experience on a b-series engines checks this out.

And welcome to HCF.
