to start off i have a redtop sr20det with full exhaust and fmic and i searched...after i had searched for a while i found a post with a formula that takes horsepower at the fly and converts it to how large of injectors you need at a certain duty cycle.....with that in mind i found at 80% duty cycle the stock 370cc injectors are good to about 320hp @ fly....to me this doesn't sound right(i will try to find the thread)....so on to my actual question....i am looking for injectors to go along with a Z maf and my t28. I plan on making roughly 250-270hp. Which injectors should i get; the s15 4??cc, or go with 550cc. I plan on rom tuning. Thanks in advanced..
