getting a 2.3L stroker kit. can't wait! I was wondering if the stock injectors would be able to handle the extra 300cc of displacement. If not, what size injectors would one recommend and would I need a new fuel pressure regulator for the bigger injectors or is the stock one good? Any input would be greatly appreciated. thanks.
btw I plan on getting a custom tune by dynoflash as well.

current mods:
3" TBE
Cat delete
Megan turbo outlet
Megan Headers
MBC
Walbro 255L FP
K&N drop in
Dynoflash mail in reflash
(stock turbo and cams)

 

No, I had to upgrade to a 660 just to do cams and all the other bolt ons. You want to keep
the duty cycle in the middle, not at 99 percent

 

And also.....I would look into Turbo-trix for the custom flash

 

Whats your list of mods bro.... do you have the fuel pump too?

If you're sticking with the stock turbo I'd go with 720s. You might be able to get away with 660/680s but you'll be pushing the limits in terms of duty cycle, especially if you visi the track and turn up the boost. If you think you'll be upgrading to a larger turbo I'd go with 850s. On my stroker set up with a GT35 and 850s I'm seeing injector duty cycles in the neighborhood of 60-70% at 43psi. I'd need to pull the logs since the last round of tuning to confirm. Ideally you don't want to be running any higher than 85% IDC although many tuners will push injectors into the 90-95% and haven't seen problems with injector lock up.

 

thanks man! much appreciated. Just out of curiosity, what additional mods do you have and what kind of numbers and/or track times are you getting?
