They don't use JCW Nozzles. they are made from scratch that way by bosch.
Check the link above for other sizes. Not all Bosch injectors have the same dual cone pattern.
The Helix/Bosch injectors respond very quickly. They also have a very linear fuel curve. Superfine atomization makes them easier to tune as well. I have had great luck with these.
If you are going to buy the injectors, buy from Helix. They are the same and $15 cheaper. Support forum vendors. I would bet that helix can get most of the other injectors listed cheaper too.
BTW, Neon SRT-4 injectors have the same pattern. 450cc.
