Great question.

I plan on turbo before injectors. Stock sticks can supply more fuel than the stock turbo can feed. It makes the decision easy for me. No matter what you do, you'll need custom tunes to fit. You HAVE to get custom tunes for single shot injectors, so be sure to add that to your budget. Tunes aren't needed for a new turbo, but, if you are going well outside the factory specs, your performance will suffer, so plan for new tunes.

I smart and/or rich man would plan and save for both at once, that way you only need to pay for custom tunes once. I'm neither, so I go for easiest first. I can change driving habits for a turbo. I can't go to the store with single shots.

Meh, what I plan and what's right don't always equal. Before you install the new turbo, wait for a few other folks to chime in that know better than I. I am simply planning with what I've experienced.

I'd go injectors first.. Unless you're set on stage 1's I'd go with stage 2's.. you can have them tuned for most potential of your stock turbo without burning it up.. Then someday if you feel like upgrading the turbo you'll have enough fuel. You'll have better low end response and torque.

With the correct housing the 38r will be better all the way around.. spooling, boost, etc. But with the wrong housing it will be laggy, Even with your oem injectors maxed you won't have reached the full potential of the 38r.

Someone should chime in with a little more personal experience with both.
I'm planning on running Stage 3 250/200's for about a year before i can afford an H2e so this is just my two cents..

Macon has a good point, you have to include the tunes with injectors, not to mention gauges.

If you're planning on only one or the other the turbo should be chosen..
If you're trying to add one part a year like I am then you can run detuned injectors until you can afford a turbo without adverse results.

Should have went with injectors first, but both would be the best option if possible.
Stock injectors with bigger turbo, you will most likely not see much gain.
However if you just do injectors and get your custom tunes, they will need to be refined for the new turbo as well. Its like a catch22. This is exactly why I did injectors and turbo at the same time. However in my case, I still need fine tuning and had 3 revisions on my tunes to get where I am at now.
