any need to upgrade from stock how does one go aboust figureing out what one needs?

i'm lead to believe that i ahve 1-2 running rich and if thats the case i can swap them over when i swap the cam in.

NO need to upgrade. I ran the stock injectors on my with full bolt ons with only 85-90% duty cycle so with your smaller injectors you should be fine. If oyu do upgrade go to the 31# 8.1L injectors.

 

thanks i woulda pm'd you but now newbs can search for this too

 

I have almost the exact same cam lpe gt2-5

My stockers get to 100% duty cycle around 5200 rpms wot at 6200+ I see around 120% not saying You'll see that much with just a cam. Ive got head work and full exhaust.

The 8.1 truck injectors are an easy cheap swap

 

Where do you get these "cheap" 31# 8.1l injectors? I'm in the market for some.

 

ebay mainly they can be had for 120 all the time

 

How much hp are they good for? (Sorry to hi jack the thread)

 

IMO personal opinion they will be good for 450 or so crank hp since many inluding myself have hit close to 400 crank hp with the stock 24.7#ers or whatever the stockers are.

 

cheap is relative to upgrading to bigger injectors, your in the right place Im sure some will pop up in the for sale section

 

I found 31# 8.1 injectors on ebay for $95 shipped a few weeks ago
