bigger injectors

[jevrem]

Can someone tell me do I need to drop fuel pressure if I put on "AAN motor" a bigger injectors "440cc for 3bar pressure".

i am not 100% sure what your asking, but it sounds like you want to know if when you put 440 injectors in your AAN motor, do you need to change the fuel pressure? is that what you mean?

[jevrem]

Yes, that i ment.

PS. Sorry for my english.

[chucka4]

no problem jevrem, your English is 100 times better than my Serbian.

as for the injectors, are you also doing a turbo, chip, intercooler, exhaust and anything else with it? i think if you just upgrade the injectors, it wouldn't be that worth it unless you did all the other upgrades as well. some one else might be able to answer this one better that has already done the upgrade though.

Yes I already buy a FMIC, tubular exhaust manifold, fuel pressure regulator, 3" downpipe, chip, and I plan to buy a gt3071R turbo and some more parts that must be change because of increase power. I am only interesting for injectors because they are 440cc at 3 bar and the stock fuel pressure is 4bar. Does that make a problem?
Or I must by fuel pressure regulator to set fuel pressure at 3 bar. And if I set this pressure at 3 bar, can I make some damage to motor.
