When do you need to upgrade your fuel injectors? I have a second gen B16 with a stage 2 revhard turbo kit with stock internals and injectors. Running at 9 psi. Thanks.

 

you should have replaced them already

 

replace at anything over 7-8 psi or run the risk of leaning out and breaking something.

 

When the duty cycle reaches 80% or more at a relatively low rpm...

how can u tell that.

 

My stand alone can tell me at what duty cycle i'm at...you can get something like the Apex AFC, which will tell you your duty cycle

 

investing in something just to tell you duty cycle is not neccessary and the AFC doesn't tell duty cycle anyway. You need to invest in a air/fuel gauge at the minimum to see if your running lean/rich under WOT...or a J&S safeguard that detects detonation. If detonation is present under wide open throttle or part throttle at whatever boost and RPM then you need more fuel. More fuel via an adjustable fuel management system and/or larger injectors if the stock ones are unable to supply the needed fuel.

 

Adjustable fuel management systems, what types are available? Especially on a limited budget? Thanks for your help guys!!!

 

damnit i want a s200b but i got no money

 

well it depends on how much more boost your trying to run. Complete stand alone system can be had from http://www.hondata.com. It all depends on your needs.
