When you say "stock ECU", I am assuming that you mean that you will get your current JWT ECU reprogrammed for turbo use. Right?

As for the stock 259cc injectors, how much "boost" you can run is dependent upon what kind of turbo you plan to use. 10 psi on a T3/T04E will produce more airflow than a T25 at 10 psi.

JWT's turbo kit uses the stock injectors with a T28 at about 5-6 psi. I would not run more than this amount of boost with a T25 or T28 on the stock injectors.

I would at least recommend switching to a set of 370cc injectors from a late model 300ZXTT or Infiniti Q45. This will give you more headspace so that you do not max out your small stock injectors.

You can even get JWT to do a 4 bar program with the 370cc injectors. This will help even more.

Good luck,

Hey Russ, it's your Daddy! Dude, why would you even THINK about running stock injectors with a T3/T4? Remind me the next time I see to pimp slap you! At the very least, run the 370cc's with the JWT ECU upgrade. It's only $100 plus the price of the injectors. I thought you said you wanted to be fast?
