I have already got new pair ID1000's that i was going to use as secondarys and factory secondays that i was going to use as primarys.I have sec/primary top feed kit so want to do aftermarket primarys now too, Would u reccomend using 1000's in primary and secondary or going ID 725 in primary and the 1000's in secondarys.
Or 1000 primary and bigger secondarys.
Running factory motor to4Z turbo full exaust,pump regulator PFC etc.. any help or ideas would be very helpfull i would like to do setup were i can use the 1000's i already have

1000 may be maxing those secondaries out.
I'd opt to keep those 1000's and use them as Primary and grab a set of 2000 Secondary.
That setup had a good transition on my FC and I personally plan on using the same on my FD engine with my old T04s.

If you are using bosch ev14 / ID injectors they are supposedly really easy to get to run really good on idle even if you go with the 2000 injectors.
So i guess its gonna be hard to get TO big injectors...

Just a note that my FC ran real good with the 1000/2000 Id's.That is why I wanted to transfer the setup to the newer FD engine setup that I have planned to go in this FC.
I am in the middle of getting all the parts for it.I am finding out though that the old injectors had smaller bore for the rails,so I need the 14mm hats.(Fc took 11mm hats)

im running 850 primary 1680 secondaries with a t04r and stock ports, if you wanna use the 1000's you could always test swaping the secondaries into the primaries and putting in the 1000's as secondaries. check to pfc to see your duty cycle and if you need more go with the 2000's

That's the thing.
Lots of Fd guys are running 850/1300 so if he already has the 1000's then keep them and use them as Primary.They will transition well to whatever Bigger injector he gets as Secondary.
If he uses the 1000's on Secondary he will Hit the MAX.he will run out of fuel.

Hell I did on an S5 TII and an RTEK,with a BNR Stage 3,so if this OP has an FD engine he will too(run out of fuel if he uses 1000 Secondaries)

Cheers for the input guys, i will use my 1000s as primary and go for 1680 or 2000 for my secondarys.Thanks for the help
