New injectors...What kind of investment am I looking at?

What i said about, i have never been much of a performance mod person. I would probably look at about stage 2s if im doing that do i need a bigger turbo if i do that? Will my sct tunes need to be rewritten?

You'll need custom tunes going to single shot injectors. IMO, if you drive sensibly, with good tuning, you could run the stock turbo. It's not an ideal setup, but it will work. It sounds like the WW G2 would do fairly well with stage 2s. A 38r would be better though.

I believe you will need an upgraded clutch to hold the added power.

As stated, with any single shot injectors you will need the tunes adjusted.

In my opinion, I would say if you are going with stage 2's, you will need at least a 38R. You can have the injectors tuned down, but what is the point of getting stage 2 injectors if you cannot use them to their full potential?

You may see slightly better mileage, but the main reason for them is to create more HP/TQ.

Couldn't have said it better. Also to everyone saying get a WW2... WHY???? Changing a compressor wheel won't change the fact that the turbine side and shaft is to small, all it will do is give you better airflow if the turbo can already handle that much fuel, you aren't going to get a stock turbo to start handling big injectors by changing a compressor wheel. Having a turbo that is able to handle the injectors usually means that the turbine size has to be big enough, that's where most of the issues stem from not from lack of air.

Not to mention, the stock turbo is limited to what boost numbers it can safely handle because of the thrust bearings.

Thank you, forgot about bearings in the post too.

Forgot to also talk about this, yes you will get more hp. But I would rather have a high hp number and low torque number. Sure, it sounds cool to say you have xxxxft/lbs, but does it sound cool to call your buddy to tow you home? Torque is what break these motors, not necessarily with that small of an injector. Really, IMO if you want to run bigger injectors talk with your tuner about pulling fuel down low to limit torque and help them motor live. The reason I say this is I ran bigger numbers on a pmr block because instead of 12-1300ft/lbs (made up number, never have cared about torque) my truck would put down a lower torque number and be safer at a certain hp level.
