Alright, in my Ka-t I'm shooting for 500 hp. I have a couple of questions

What does a 1:1 fpr do? (Why upgrade)
About what size injectors do I need?
What is the most cost effective setup?
Side or top feed?

Sorry for the noob questions, just trying to figure this all out.

im not sure on this just a guess.. the 1:1 fpr may be raises the fuel pressure 1 psi for 1 psi of boost

for the injectors you can calculate it on the rc injectors webpage

don't know the stock fuel pressure in your car but if its around 43 like in hondas you can get away with 880cc injectors probably using a 1:1 fpr

 

1:1 is stock son
