Ok so I have the pin readouts... not sure about injector size. What year Catera is it? This one is for a 99' but the 97-98 are probably different due to non-electronic throttle control.

I got the injector info from this site:
http://www.v6calibra.com/tuning/v6_calibra_tuning.htm

The C25XE is basically the same engine family as the Catera (which is an X30XE or SE iirc) and so they may or may not be the exact injectors.
