except for one .. do I really need 555cc injectors, I am pretty much stage 3 and I have no plans for upgrading turbos, maybe a new car in the near future, 350Z or G35 coupe .. I have no electronic boost controller, or bigger ICs even thought if I go with 555cc I might get those last 2 items I mentioned, I guess I don't want to open Pandora's Box... next thing you know I am pulling my engine out and sticking big ball bearing turbos in there !
