As long as one uses them as intended, which is as a momentary traction control, most any solenoid will work. If you try to use one with the idea that it will act like an ECU with an EFI injector you will be disappointed.
I will say that the small purge-sized solenoids are more adaptable than the large sized ones used on nozzle systems. For more detailed information please read a review I did on a controller a while back. I think most of the answers are there.
Have a safe race,
