Can anyone tell me what is the best injectors upgrade for the FC? since i been quote 180 pounds to get the injectors cleaned so i thought may as well buy a set of new upgraded ones.....any know knows?? thanks
Sam
Not sure, I know you can get 6 2nd hand ones on Ebay.com for about $150 from time to time. I had a set of recon ones in my EGi, think I paid about £30 each, that was from Rotechniks.
I assume you\'re talking stock size?
Sam you must read your \'own\' threads carefully.
You posted on this before and was answered.
It\'s not £180. to clean your injectors..
I just got a set back from WGT and it was £12. each to clean!
ok so can anyone tell me what is a good upgrade for the FC since the one i got now is stock size.
if you put bigger injectors, you need a programable ecu to get the best out of them. If you just stick bigger ones in they will run at the same duty cycle and run too much fuel. I fitted 1680 cc bosch ones in my stock FC rail with a little modification. They are quite cheap and you can buy virtually any size.

i will be getting the power fc too so i guess will be ok.....but do u use 1680cc for all injectors.....and i think fc only need 4 in total right???
what sort of modification do i need as i m not familar with the injectors..
i use two 550cc primaries, (the original ones) and two 1680cc seconary ones,, this set up is good for 500 flwhp. with the bosch ones, you need to change the wiring plug to the bosch type which is easy enough, machine (drill with a reemer) the holes in the rail to take the slightly bigger bosch ones, (its less than a mm) then file or grind a little off the lower intake manifold where the rail sits to make it sit a little lower.
The thing to bear in mind is that the stock FPR is fixed in the end of the rail, if you get a pump big enough to flow 1680 cc injectors you will need a new FPR as the stock one wont return enough to the tank and you will run too much fuel pressure. I just cut mine off and welded a pipe to it and run a seperate FPR.
thanks for the reply...are these 1680cc injectors same as yours?

i m not very good with wirin and all that...may b i will let someone to do it....:P
yep...... same injectors
sorry for another question...so whats is the difference if you put 800cc all round instead of only 1680cc at the secondaries???
nothing, just add them all up to get the flow, there is turbo II running 4 x 1000cc injectors. That is another option. You can buy 1000cc injectors from Tim (RX motors) that will fit straight in your rail without modification. You need to decide on how much power you want. You could probably run 300 rwhp with just putting a pair of 1000cc inj in your secondary rail. Some people say if you put too bigger injector in your primaries your idle and low end will be affected. I didnt find this with 850 primaries on my FD.
antincuk...thanks for you kind help, i want about around 350rwhp, so i better get some bigger injectors now, 1600cc is actually quite cheap but i will ask how much for 1000cc inj.....u know what sort of price i should be paying for 1000cc?thanks again
not sure about price for 1000\'s, there are a couple of different makes available.
speak to tim at RX Motor\'s he has them in stock generally. Not only do i run them in my car but he does. After a bit off experimenting last week i doubt i will change to bigger. as i now know what the can flow and when they don\'t stop working under 10bar off rail pressure you know they are reliable. 1000cc all around have never had any issues
10 bar!!!! your a pressure addict!!
well you have to see when they stop! Don\'t you:)
I have two 1000cc RC Injectors that have about 2000 miles on them doing nothing at the mo?
