2-4 Injector Nozzle Pressure

[drumgold]

Hi there,
I'm new to the forum so hello to everyone.
I've got a 1998 Nissan Terrano 2.7Tdi SE Auto which i've had for the past sixteen years.
I have a question about the Needle Lift Injector opening pressure and 2-4 Injector opening pressure.
The new Needle Lift Injector is opening around the 1,670 PSI mark but in the workshop manual for the Terrano it says the opening pressure for Injectors 2-4 should be between 1,849 and 1,191 PSI using a new nozzle.
I've always set 2-4 Injectors to the same opening pressure as the Needle Lift Injector and the vehicle has always run fine but is this correct?,is the 200 psi difference between the NLI and 2-4 Injectors correct?.
Thanks.

Hi mate, I have never set the pressure different between No 1 and the others cannot imagine where that info came from, Rick

Hi Rick,
Thanks for your reply.
Same here,i've always popped tested the NLI first then set the other three injectors to the same opening pressure even though the workshop manual says differently.
Anyway thanks again you've cleared that up for me,it could well be that the information in the workshop manual is either out of date or incorrect.
