Stu Posted March 7, 2016 Share Posted March 7, 2016 Go for Mitsi 510cc or 560cc injectors - they have a very good spray pattern for a OEM injector. Quote Link to post Share on other sites

Stu Posted March 7, 2016 Share Posted March 7, 2016 Will fit the stock rail but plugs need changing and ballast resistors need to be fitted. Both easy to do.

Duduglanza Posted March 8, 2016 Share Posted March 8, 2016 i use 550cc mazda one on my emanage. fittef for 2 years now and all fine. direct fit aswell Quote Link to post Share on other sites
Stu Posted March 8, 2016 Share Posted March 8, 2016 I ran those for years on my first 4agte. Idles fine etc. Have had other engines come thru that ive swapped 550's for better spray pattern injectors of the same size and they have picked up power at the same boost etc. The better spray pattern/atomisation does make a difference if you can be bothered changin plugs and/or running ballasts. From memory denso make a 550cc injector with the stock plug, can't remember the impedance though, Quote Link to post Share on other sites
