What size injector can I go up to with a stock pump and turbo. I'm go to upgrade the turbo and pump later since they have 260k on them .

 

First it depends on what your Fuel Psi is at now running WOT. Below 45psi at WOT, and your injectors will suffer.

IMO, with a healthy HFCM (55-60psi @ WOT), 155/30 injectors would be my max. Any bigger then you might have to have your tune written to pull out fuel.

 

I can drain my fuel pressure down now with stock injectors and a hot tune.

Monsterstroke is this for a 6.0 or a 7.3? I see your sig says a 2000 powerstroke, but you're in the 6.0 section...

What other mods do you have now?

 

Yes. It's a 7.3. I see I posted in the wrong year. Thanks for catching that.

 

I'll move it for you, let the 7.3 guys handle this. I'm not sure what can and can't be done on a stock pump for a 7.3. My guess is they're going to tell you to get a regulated return for sure though.

 

Whats your HP goal?

 

150 to 200 hp gain.

 

That doesnt help much...

Assuming you have a chip now, your at about 280-300RWHP...

So you would like to be at about 450-500hp...

You will need...

Studs $600
valve springs $100
fuel system (regulated return, 5/8 pickup and such) $700
turbo (38R, or H2e or S300) $1500-$2700
Injectors (238/100, 238/200, 250,200 or like) $2000
Tuning to run it... $400

Then a tranny to hold up... $4000

Looking at about 8k give or take a few hundred...
