I need some help selecting an impeller for my gtx 215... My current list of mods are as follows...

4 inch kanaflex intake with velocity stack
Riva top loader intake grate
Riva pump wedge

I plan on.. After this season.. Putting in an et wheel with bigger injectors..

Is there a certain impeller that will work well with my current set up.. And after this season with the future mods?
