I have the peak and hold ones now with the resistor box. I was wondering if i could use the 290cc satureated ones and just disconnect the box? Would that like 45cc make a difference and be bad or are they the same just one w/ the box? I am shopping for new injectors and was wondering if i could just buy the sat. ones.
thanks

 

the saturated ones need to run at around 50 psi
the peak and hold run at 38 psi
meaning they flow the same in use.

 

you can go to rceng.com and use the injector calculator , but like values said, if your runing an obd1 ecu your ecu is expecting 345cc, if you put in the 290cc you need to take out the resistor box and turn up the fuel press to get them to flow like 345cc..

if your obd2 then your ecu is expecting 290cc , so you could get the 345cc and turn down the fuel press and add a resistor box..

depending on your setup those are your options.

 

ok thanks guys
