Because one injector will make the bottom end of that range fine, but will be pushed to make the top end, where another injector will make the top end of the last range...

A stage 2 will make 340hp easy, but will struggle to make 400-410... A small hybrid (200cc or so) will make 340 without breaking a sweat and 450 is pushing it... A Standard hybrid (238/80) will make 400 easy, but struggle to make 500... and so on...

450hp guaranteed build...

38R
238/80 or 238/100 hybrids
Stock oil...


No studs, springs, or such are NEEDED, but if your going to run it hard all the time it is recommended.

You will need a good solid tranny to go behind it as well.

A good Regulated Return fuel system is also a good add on.

Great, thanks, you have been most helpful, now to look up how to obtain a regulated fuel return, unless you have a recommendation? I have a solid tranny, has alot of upgrades and hooks up strong. What are the stages about, I heard that a stage 1 air intake is a filter in the stock box, and a stage 2 is a whole new box, is that true? What other stages are there and what are the differences? Whats the difference between a stage 1 injector and a stage 2 injector and so on?

Driven Diesel 7.3L "Standard" Regulated Return Kit

Best kit on the market right there...
If you want to spend a bit more and delete the factory fuel bowl this is what I have...

Driven Diesel 7.3L "Bowl Delete" Regulated Return Kit

Dennis has changed it from the kit I have I see and I like it even more now...

You may think you have a built tranny... But I have gone thru 5 "built to the hilt" trannys from local builders... Maybe it will hold, maybe it will not. But dont think its bullet proof, 800fp of tq will eat them up.

About how you say... I have an AFE stage 2, and its a great filter set up, however you can go with a simple Filter on a stick (tymar and knockoff's) and get about the same airflow.

Stage 1 injector is commonly a 160cc injector with a stock nozzle. Stage 2 is commonly a 180cc with 30-50-80-or 100% nozzle.

Stage 3 is what most call a Hybrid, but a hybrid can be anything you want it to be... from 200cc to 400cc or more. With Nozzles from stock to 400% or more...

I can deffinently understand that, but Iam not going to be using it to near its full potential, so time will tell. What kind of upgrades would you recommend when I have the tranny rebuilt?

I was looking at the S&B cold air. Is there a stage 3?

What % is a stock nozzle?

0%

ok, starting to get it, I think, LOL, thanks.
