Need to either clean or replace injectors on zc motor. If you put dsm or higher flowing injectors on a motor that has always run a bit rich would you recieve way to much fuel or normal flow.

 

You can run the DSM's and not be rich. It is all in the tuning. If you just plug the DSM's in your car, it probably won't even idle. You could just buy some injectors from a 4G Si, or get yours cleaned. Look in the yeallow pages for fuel injection services.
