Injector questions!!!

[Briou]

Ok so I have searched on here google 240sxforums and some other sr sites and I can't find the answers to my questions.

Ok I bought these injectors from a fella on here at a really good price but there is some stuff I am unsure of. I was told these are 1000cc RC injectors but they don't have the RC sticker on the. They have 2 numbers on them (4270) and (17113744). My main question is this: will these work with the greddy intake manifold and the greddy fuel rail on a s13 sr20det? Also do i need some kind of o-ring at the bottom of the injectors? Seems like there needs to be an o-ring down there.

Here are the pics.

that looks like a MSD injector either or i believe there low impedance(peak/hold type) injectors so your gonna need drop down resistors or a resistor box to run those cause the SR uses high impedance injectors, they'll fit the greddy intake manifold but not to sure on the rail cause its obvious that is a "MSD style" injector you got yourself and I'm positive what you have there is a 14mm top and the greddy rail injector bore is only a 10.5-11mm... not to sure about those product numbers though, im sure someone on here does. hope that info helps a little.

btw if that's troubling to do all that i'd sell that stuff and op for a jgy rail 140 bucks and some injector dynamics 1000cc 460 bucks its a bit $$ but VERY good setup... the ID injectors are high impedance so no worries about soldering resistors or sourcing out a resistor box.

every RC injector i've seen has the cc's engraved in them

ok yeah these won't fit in my fuel rail...anyone want to trade for some that will??
