So I'm preparing to dyno tune the car within a months time. I will list my mods below. Do you think the DEK injectors will be able to help or would you recommend upgrading to say 350z or in general any 3.5 injectors? I rather to it proper this time around with out going back and worrying about being restricted by something minor such as injectors. Aslo would I get any benefit of adding a fuel pressure regulator as well?

Thanks, Listed below are my mods.
- 350z cams/mildly ported DEK W/VQ35HR springs/retainers
- Cattman Headers
- Greddy EU
- Innovate WBO2
- Maxxtunning VB | Hayden Tranny
- Custom Maxima Greddy Evo 2 catback
- Cattman Fastcat
- NWP DE-K manifold spacers
- Remove 00VI powervalve
- 3" Custom MAF w/velocity stack
- Pathfinder TB

 

DE-K injectors = 290cc = 350z injectors. Aka larger than FWD vq35 injectors. Your injectors will be fine. If anything I'd just raise fuel pressure or upgrade the pump but I seriously doubt you will need to do even that.

 

Since you have direct control of thee injector pulse using the EU you do not have to upgrade the injectors to reach your AFR target.

 

Technically speaking he could run into a mechanical limit for injector flow at a given fuel pressure (if the IDC was high enough) regardless of engine management options. But given the fact that his injectors are larger than FWD VQ35 injectors (which have been able to reliably support over ~300CHP w/ stock pump) I think he should be fine.

 

I have dek injectors

 

Understood and I recognized that fact in post #2. You will be fine.
