I have the info I need now, thanks.

The RS2 uses 0 280 150 984 injectors which are the Carrera RS 444cc/min
units. These offer 28% more fuelling that the standard S4/S6 951
injectors (346cc/min). Aelred commonly fits a 'green' injector 0 280 150
803 which is a Porsche 944 Turbo unit delivering 382.46cc/min, a 10%
increase over standard.  Interestingly, the RS2/911 injector is the
cheapest of the pack at my local Bosch dealer!

One of the reasons for the original question is that a certain US tuner
has been selling Corrado injectors as an upgrade. These are specced at
280.5cc/min with a multi-jet spray pattern. Whether this type of spray
pattern is better in a multi-valve enviroment is beyond me, although the
flow rate is obviously much lower than the standard item. A questionable
upgrade. (Bosch have more recently introduced an 0 280 155 range of
injectors that have a disc fitted to the end of the injector to improve
fuelling in a multi-valve situation, although these tend to be only
available in smaller flow rates)

How much do you guys pays for Bosch injectors in the US? The 984
injector at my local Bosch (trade) outlet is 71.84UKP each (~$115)
