However They are about 23.5 Lbs per hour ( as fitted to 3.9 to 4.6) vs the GM ones at 18.5, and on a 3.5 would need an interceptor to work properly. Once you get to this stage you are probably better off starting again with a 14CUX setup, aftermarket eg Haltech or DIY Megasquirt.

my question was for the 4.6 that I just had installed in my 94 disco. It had new injectors put in it but I'm not sure what type, I was thinking of down the track if I have to replace them.

Sorry I hadn't realised you were not the original poster.

As above, but do you have the 14CUX chipped?

If not it will be lean up high and the chip eg Tornado will improve the performance greatly.. BUT note the earlier post where a for GEMS the Tornado is tuned for o2 sensors, so check this before buying.

In my case I put in Bosch gen 11 4 hole injectors. apart from probably a better idle stability, I didn't really notice much difference, but mine were changed in conjunction with many other changes including a Thor manifold and I have a Unichip.

Wade from Graeme Cooper told me mine was richer down low with the four holes but this was before o2 sensors were added.
