i am working on my s5 turbo swap into my s4 n/a and i am looking on upgrading the fuel system. i am looking for new fuel rails and larger high impedence injectors something like 720cc or 850cc. I am also going to go with a walbro with a fuel pressure regulator and a apexi safc to tune everything. my question is where can i find fuel rails and high imp. injectors?

 

Marren Injection.

Your gonna pay out the *** for high impedance injectors.

 

could i run low impedence injectors then on my s5 turbo engine?

 

Of course you can. You just have to use resistors.

 

oh yeah! where can i pick some up at on the net?
