At what point should I uprgrade my injectors? In about a month I plan on hooking up my new parts I ordered while on deployment. I have or will by then have.... Intakes/down pipe/high flow cat/ racing beat cat back/Power FC/Denso fuel pump. I just want to make sure that im not going to run to high of injector duty cycle. And if im correct its the secondary injectors that need to be replaced right?

Also anyone have any recommendation on what sized to go with or nay specific brand, this would be awesome. I plan on getting the Rx7 Extreme fuel kit in the future but im doing that when i upgrade to single turbo and get my engine rebuilt/ported. Thanks

 

Anyone? All i know is that stock primaries are 550 and you dont want to change them because you will have a rough idle. and the stock secondaries are 850. I dont know if im better off going to 1300 or the 1600 injectors. I dont know what else i need to go with them or if they just plug right in and work... any help here would be awesome.

 

what's up RR93, i just purchased a long list of items as well that i will be installing in sept. when i get to go home. i went with rc 1300cc secondaries and was informed that this should supply sufficient amount of fuel for my upgrades. i also purchased the bnr stage three turbos and plan on turning up the boost a lil bit. just to let you know what these should be able to support (as i have been informed) here is a list of my engine mods

bnr stage 3's, hks rs intake, ceramic coated uim/lim, smb down pipe, resonated mid pipe, apexi n1 duals, rc1300 secondaries, large smic, piping, and duct, rob baily's solenoids, koyo n flow radiator, samco hoses, greddy profec b spec II, hks twin power ign, and of course all new fluids and filters. i already have a pfc and commander.

don't know if this will help you out that much or not, but i thought it may give you an idea. i plan on running around 15-17lbs of boost.
