What would be good injectors to upgrade to in a 325?

Adding bigger injectors might give you a tiny gain. Going too big will cause your car to die when you stop on the gas. Maybe if you had a big intake so you needed more fuel to mix in otherwise you'd just run rich the whole time.
I'd say just have the injectors cleaned and put the money you'd spend on new injectors into a chip.
Just my $0.02

if this was an POS car then you would probably see a gain, but because the DME determines how much fuel is neeeded, larger injectors won't automatically flow more fuel; they have to be told to. If they did flow more you just be running rich.

But why the're different injectors for 318 / 325?
BTW, it's right the DME controls the flow!

Now when you say "controls the flow" you are talking about pulse width? I would assume because the pressure is controled by the regulator so because the DME reads the signal from the MAF, all conversions for baro.,temp. and speed are all accounted for. SO adding bigger injector wont have a power gain unless it is running lean for some other reason.
