Ok i'm really not sure what i should do..

i have a turbo system similar to the bnr stage 3(i have the knightsports), so i'm wondering what fuel setup i should do.. here's my dilema.



I want to run stock 550cc primaries and upgrade the secondaries to 1300cc but in my current location they only have 1000cc and then they jump to 1600cc



The reason why i don't want to upgrade to 1600cc requires a new fuel rail, a fpr, and new lines.



QUESTION:

I'm wondering if

2 x 720cc for primaries and

2 x 1000cc for secondaries will be fine

for 11psi on the knightsport turbos ???



since people use 4 x 850cc (flow rate is 3400) and 2x720 + 2x1000 also = 3400 would this setup be ok?

feel free to pm me or reply to this tread, thanks in advance.

If you are using upgraded twins, and plan on more speed or more boost in the future, I would recommend upgrading your whole fuel system from the pump to the lines, rails, injectors, and FPR. I would do this for not only a performance benefit, but also a safety issue. You can PM me for anything that you might need.



Good Luck-

go ahead and upgrade your whole system...better to get that out the way and you never know what the future will bring

why dont you just use the 850's for your primaries, and go with the 1300 for the secondaries



that will be more than enough for what you need

Run two rx7 fuel pumps strat to the fuel regulator and put the 850's and 1200's in. Here a good place to get a fuel rail set up.
