My question is ,are the gtr and gti-r injectors bolt-on to my stock fuel rail and stock connectors?I think both are 444cc but are they the same?So do I need some other modification concerning those injectors(resistors,etc).And how much are they worth?

They will fit you fuel rail and connectors perfectly. The CA harness already uses low ohm injectors, so no need to change anything there. You will need a new tune to your ECU or a piggyback or something to properly control the larger injectors. They should run something like $1-200 for a used set...

What are you putting these injectors on? A CA or a SR?

I think the GTiR injectors are side feed, while CA are top feed. So they wont fit at all if i am correct about the GTiR being sidefeed.

Nope GTiR injectors are top feed just like CA injectors. They're 440cc. Skyline's are top feed and 444cc. Both low impedence.

From what I know, they're good to a little over 300whp, depending on tuning, turbo, etc.
