DOHC ZC Fuel Managment
 

Im gettin ready to boost my stock zc really soon. I only want to run like 5-6lbs, will my engine hold up with a vortech 12:1 FMU and dsm 450cc injectors? Or can i just use the fmu with stock injectors?

Oh jesus.....I could rip your ass apart right now for soooooo many things, but I'm going to lend a helping hand to a fellow ZC owner. :)


Ok, you can't use any oversized injectors without some sort of electronic device or modded ECU to control them(slow them down). At such a low level of boost I would say an FMU is right up your alley. If you ever want to up the boost(and you will)you should buy some bigger injectors(450cc are perfect)and look into some real fuel management like TurboEdit(OBD0)or Uberdata(OBD1). The FMU and your stock injectors will be fine for your goal.

BTW, fuel management questions usually go in the "Engine management" section. ;)

thx for the help
I plan on using a t25 turbo. will the zc hold up to 8psi with stock internals?

Re:DOHC ZC Fuel Managment
 

i think that those engines are pretty much bullet proof, i was boosting one with a t25 at 12psi without proper tuning ran perfectly

Re:DOHC ZC Fuel Managment
 

Vortec FMU running 8 LBS with a T25 your pretty safe.

Haha, that's awesome. You're already raising the boost before you're even boosting. 8)
