Fuel Injectors. Please help!
I am planning on upgrading my fuel injectors. I am running 13lbs on the stock ones now. I want to be able to run 14-15lbs. I have a bigger fuel pump, and lots of nice upgrades. I think it was rx7.com that told me all I have to do is upgrade my primaries to 850cc injectors. Does this sound right? if so would these work for what I need?

Not sure why you even need to, if you are still using the stock turbos. I ran 15psi putting down 340 rwhp on stock injectors, never had a problem. This was even on stock FP.

Search for Garfinkle, he does the modifications to the primary rail for a good price.

hmm, but wouldnt I be running very high duty cycles? Is it bad to run high duty cycles? I am new to the fuel system aspect. My injectors have 47k miles on them. RX-7.com told me that 850cc primarys would be a good idea, and he said you would not have to modify the fuel rail. He was also telling me that he can sell me a interface that hooks my car to my labtop, and I can download the right setup to my car. That is pretty frickin cool. Sorry if im a little behind. Does anyone do this?

Very interesting thread Mahjik.. By the way you are the man! I am guessing i need some pretty good tuning to be able to overcome the high duty cycles though. I am running 13lbs, and I forget what my duty cycles where, but they were getting up there. From what it seems High Duty Cycles are not as important as A/F, and from what you said "never heard anyone that has blow an engine due to high duty cycles" mabe I will just get it re tuned with my stockers. I want a reason to re-dyno it anyways I added the efini y-pipe, and power pulleys. I figure with 14lbs of boost, and these extra mods I should be closer to 300rwhp. At least I would hope so.
