How big injectors can u run on Stock S5 Fuel rail????

I think the 1600cc's fit if you mod the injectors a bit. or you can drill the hole out a bit bigger.

with no moding. I think under 1000.

Why you want to run larger fuel injectors???

The largest you can go on the primaries and still hold an idle is about 850cc - bigger than that and you can't get the pulsewidth low enough. 850cc is pushing it as is.

You can easily go up to 1600cc secondaries.

Of course, with larger injectors you need something to control them properly.

I'm with Ted - what are you trying to do?
