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?

Bump... help!
|
Read this.... http://www.wvinter.net/~flanham/wlan...el/850pri.html
|
so am I right to upgrade too 850cc primaries, to make 15lbs of boost?
|
I would change the secondary's to 1200 or 1300..
|
just get those and send them out to rc to get bored to 1300
|
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. |
If you only want to run 15 lbs of boost, there is no reason at all to touch your stock injectors.

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?

I want to be as safe as possible, but I also like the idea of a little more boost. Is 15lbs of boost pushin the little twins too hard?

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.

Mahjik if I were to decide on getting new injectors. What would be the best, and easiest way to go about it. How big? Secondary, or primary?

so your saying that 1200cc secondaries would be a nice upgrade, and give me what I want?
