are upgraded injectors necessary for the JWT 530BB kit if I run it at between 6-7 psi?

I plan to get a tune and already have a walbro 255 but dont know if the injectors are necessary since I dont have high power goals.

 

honestly, if you dont think you need them i would suggest you need to do more research about F/I.


i say yes. upgrade your injectors please.

 

i had 440's before with my procharger but am not sure at what point the injectors are past their optimum duty. also I know the jwt kit uses the fmu and doesnt upgrade injectors.

 

up to you.. rather not have my injectors being anywhere near their full workload.. gl

 

to quote a wise man on my350z.com: " *sigh* "

 

yea I dont want them at full workload but rather 70%. ill probably get some deatschwerk injectors so I dont have to cut up another harness.

 

look forward to the results..

 

I used the JWT 530bb kit with stock injectors at 6.8psi (waste gate pressure) and about 400whp it ran flawless.

 

DW injectors actually run better on the VQ than RC from what I've heard... something to do with spray pattern.

 

You can run stock injectors with no problem on wastegate boost with the 530bb kit. I was running wastegate pressure for over 3 years with 40k+ miles and I never had a problem with injectors.
