I have a greddy turbo on my zc and need to find which injector size i need, i have a zdyne gold ecu, with a built bottom end on the zc, i plan on boosting under 8psi, would 500 or 550cc Rc injectors be to big, how will my idle be affected by having 500-550cc injectors, i did a search but couldnt find anything related to my engine w/greddy turbo,

550s shouldnt be a problem, definatly not with the zdyne gold.

If you're sure your only going to boost 8psi, 550 is major overkill.. I use 440's on my D16 at 12psi and that's still alot of fuel.. I'd say 370's would be fine for you, or turn up the boost. I know which one I would do
