if you are boosting more than 20psi
you prob want to get something like 1008cc just to be safe
otherwise you will be in the same problem again later on
As to which injectors, you prob have to check with you tuners as to which one will give you a stable idle. I am getting a set of rochester injectors. They are not here yet so I can't tell you any more than the fact that a tuner in australia said they are ok at idle.

yeah that is a lot of fuel but it is good to know i dont need an aftermarket rail. Just everyone I had talked to said that the rail needed some mods to work with that large of an injector. No thanks either no more then 20psi for me have to try and get some traction. So i guess that is what I am most concerned with having a crappy idle. I have already went through one block this one is fully built and sleeved but dont want to push it much more then that. Plus dont have the money for a transmission upgrade. So 20psi is the limit

don't wait for me buddy
i've got a few custom jobs with my project, including fuel rail
so these injectors may not fit the stock s2k fuel rail
just check your duty cycle and order larger injectors
you can get custom injector of 1kcc size that fit the s2k fuel rail from
http://www.rceng.com/prices.htm
from memmory, someone on here found that even the ?685 or 750 cc injectors were reaching 80% duty cycle with only 9psi.
Jason (if you are still lurching around here
), what is your injector duty cycle at 11 psi?

80 % huh. I am not calling you a liar or anything, but 685 running lean at 9psi just doesnt sound right. Cause at 7 psi you can run your factory injectors which are what 380cc? When I took my motor out the first time it was at 9 psi and had slighty scarred my #4 cyl. My boost would spike up and poof detonation. But I see all these guys running 440cc at about 10psi so how could the duty cycle be so high for a 685 or bigger. I forget what member, but he has the yellow turbo s and was running about 23psi. Said he had 765cc, I believe and said the car was good. Didn't run lean or have any other problems. I am not a technical wiz and dont know nearly as much as the rest of you but just curious is to how the duty cycle is so high?
