i have the 2litre side feed injectors in my fuel rail (std).whats the nxt upgrade from there with out going daft on the ccs

 

it depends on what power you are aiming for what fuel pressure you are running what manigment are you useing ect ect

 

pending on how much boost/ power your using with you fez u can use the Nissan 200SX (S14) injectors. The only thing you will need is the conector end from the nissan fuel wiring loom to conect onto the injectors as the ford ones dont fit! Also they are NOT compatable with the fords ECU. u wil need an aftermarket one which i would assume u have running a turbo!

with a comparrison to fords injectors..

Zetec injectors

Flow rate ~ 160-170 cc/min - Impedance - 16 Ohm

Nissan injectors - SR20DET - 2 000 cc, 200HP

Flow rate - 375 cc/min - Impedance - 10,7 Ohm

both injectors are side feed also. what ive heard is that you may need bigger o rings to stop the fuel seeping past.

there is a site somewhere out n about on tinernet that will give u alot more info, but i cant find it for the life of me but hope that helps anyhows :

 

what are the std 2litre zetec injectors rated to

 

155 bhp, then youll be pushing the ecu, injectors & the plastic manfold to the limits as it will crack under preasure.

 

best and esiest way is to grab a focus RS inlet and fuel rail,

the std injectors will be good enough for 360bhp with std fuel pressure



i have my old ones avaliable
