Ok, if I get the 450 injectors I need to get the resistor box, but I'm not sure I need the clips because different clips that came with my Greddy kit were already installed to accomodate the RC310 injectors. Does anybody know if the injector clips that come with the Civic Si's Greddy kit are the correct fit for the DSM 450 injectors?

 

Yes they are. I took out the 310s and the 450's clipped on

 

Excellent, thanks man! One more question, people have mentioned the need to dremel. Did you need to do this? Thanks again!

Nice car, btw!

 

The clips will fit. I think people dremel something when they install this, but I dont know what ... BUMP
