Hey i am not sure if this is the right place for this question but for my turbo build i was looking to get 550cc injectors for my gsr integra and i don't know what brand to get so i was looking for some opinions ... also will all the after market injectors fit right into my skunk2 fuel rail?

well what are your goals?
RC makes peak and hold or saturated injectors, but the peak and holds you'll need a resistor box for. Or you can get some dsm injectors for cheap but they're only 440-450cc, although im almost positive the the evo IX-X? runs 560cc injectors, but again you'll need a resistor box for em.

i am looking for around 300, and those are the injectors i was looking at i have read good things about the rc injectors but the dsm's are so much cheaper do you think they would be just as good? and with them i would need the seal kit , and resistor box anything i am missing?

Just throw in a pair of DSM blue top injectors. I've found set's in junkyards.
All you'll need to fit them is DSM injector pig tails/clips. Very easy to wire.. just positive and negative.

if you run the dsm injectors theres no need to get new seal kits for em just to make em fit unless theyre cracked and dry rotted. what i did with mine was just take a dremel to the inside of my integra injector seals and bored it out a bit so they would fit around the larger dsm injectors without stretching them out. because if those seals stretch they wont seat properly.

doesn't sound like its gonna be hard to get them in but i herd they are not to reliable witch was pushing me more towards the rc injectors ...... have you ever had a problem with yours?

I never had a problem with them ever. If people can get 200k miles on a dsm without injector faliure I think you'll be fine with a set.

90$ that's a great deal but i think i am gonna need some thing a little bigger then 450cc and this might sound kinda dumb but what is it that makes precision and rc the best if dsm is also reliable and pumps out the same fuel amount whats the difference ?

honestly...the name they all push the same amount its just dsm injectors are stock and rc and precision are aftermarket injectors.

Ok but do you think there big enough to support 300hp i try,ed out the formula where you figure the hp numbers and plbs per hour to find out what size you need and i came up with 590cc does that sound to high?? sorry for the million injector questions i just wanna make sure i get the right size to support my hp but i don't wanna go to big and run rich at a lower rpm .

id say go with around a 550cc or higher if your shooting for around 300...like i said im not sure so dont quote me on it but im almost positive the evo IX's run around a 550-560cc injector which should swap right out.

yoy might as well just get 1000cc injectors, reasons why: 1. You can tune them down 2. You will get bored with 300hp very quickly and will need more injector to up the power. Its better to have too much rather then not enough. As for the guy saying "your just buying the name" that is b/s. You are buying the R&D, the spray pattern, the warranty...DSM 450s are known to stick open, don't believe me, talk to some top Honda tuners and get their opinions on em.

yeah your right i was actually planning on going higher, I have change my mind since i started this post i know it was only a month ago but i have learned a lot since then. (Its crazy how much there is to learn when it comes to going boost) .....thanks for your responses.
and one more question do you think i am going to need a regulator and gauge? I was looking at some forums and the people where saying they are not needed there only for when your trying to get crazy high HP. your stock regulator is fine for lower numbers...., but i always thought they where important for when it came to tuning but these guys are saying otherwise can some one with some more experience tell me what they think please?
