one injectors in 740cc but the only person who makes them are venom, thats the downside. your best alternative is deatchwerks becase you get the phase 2 which are much nicer and the sell a really nice adapter kit that comes with everything including seals, metal top hats, adapters and the wire harneses. i paid about $720 for all of it and i am really happy with their performance. other option is nismo phase 2 and a newer fuel rail from the 94+.
