what boost / bhp you wanna run ?? maybie 440 will do just fine as there easier to map for emissions tik over etc

I want 550cc injectors and im wondering which is compatable and have best spray pattern

[Stu]

Go for Mitsi 510cc or 560cc injectors - they have a very good spray pattern for a OEM injector.

are these stock fitment (connector plug and location) and what about the imp (high or low/resistor box)?

[Stu]

Will fit the stock rail but plugs need changing and ballast resistors need to be fitted. Both easy to do.

Hi lads what ill be looking for is a direct fit and resitors required etc but have best spray pattern and flow etc

i use 550cc mazda one on my emanage. fittef for 2 years now and all fine. direct fit aswell

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,

Aye denso make a 540cc in their new age injector which is high impedance and stock plug found in pairs in the first gen rx8

Does anybody know if these injectors fit on a 5EFE paseo rail onto a 4EFTE head?

[Charlie28]

I have RX7 injectors, direct fit
