With my upgrade list in my sig, do I need to upgrade my stock injectors?

At what HP level would I need to upgrade? If the amount of HP is not the way to determine, what is the convention?

 

no one?

 

..Kinda wondering the same thing!

 

You don't need to upgrade unless you do a larger turbo or are planning to run E85.

 

Would you have to upgrade if you got a FPgreen?

 

I went to the 780s when I installed my green. You wont be able to tap the full potential of the turbo without a minor upgrade. If I had to do it again I would go larger still so that I could tune for E85.

 

IMO-When you get to a 85%-90% duty cycle on the stock ones.

 

if your runnin on 91 octane a lot of tuners here in Cali recommend you upgrade when you get cams...

 

Stock turbo=stock injectors.
Stock ECU can handle like 880 cc i think.

 

If you log your car, you can log (IDC) Injector Duty Cycle, and you can see where your injectors are @. I have been told that the Injectors go "static" @ around 110% IDC. So anything 100% or over, its time to upgrade!

If you dont log your car, (u should) but if you dont, w/ most of the bolt ons, you will need them. Im @ 97-98% IDC w/ my current set up, minus the intercooler (getting installed tomorrow) and once I re-tune for the new mods, I will need Injectors! mods in my sig.

 

I have a evo 8 with fp green/cams right now at 78% idc on 660cc. If I downgrade to a stock evo 9 turbo on a 8 with cams, would I be ok with stock injectors?
