HKS .vs. GReddy | Top Feed Fuel Rails - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm just curious what everybody's opinions are out there.

A fuel system upgrade isn't exactly cheap... I just want to make the right decision's. (I'm running an S13 SR20 Blacktop.)
I've already been using the GReddy intake plenum, GReddy external fuel pressure regulator, and NISMO 550cc injectors. Of course the next logical option would be the GReddy rail... But, what makes the HKS rail better? worse?

Any information / opinions would be greatly appreciated!

Rails are probably the one piece of equipment that really doesn't matter which one you choose. Essentially it's a hollow piece of metal, flowing fuel. At this point you are basically buying the name.

Pick one you like and go with it.

Why? Just run stock rail with the right injectors and a good EMS> Rail does nothing but look pretty pretty much. Get a good off rail FPR like aeromotive if you're going to invest in rail/fpr area. Even then you can runt the stock FPR up to 500-600 whp no problem if it's in good shape. Your next logical step is a good EMS or a good camshaft after that On topic of max hp with stock SR FPR 500 WHP all day - . I've personally done it.

Invest is a Q45 TB instead.
