What Mod Next
 

I have been looking around to see what I should do next. Im planning on putting PHP tunes on my CS. Should lean towards injectors and fuel or turbo parts? With the mods in my sig. what estimated HP and torque am I around?

A turbo would be lower in cost than injectors and fuel, but to do a "bigger" turbo will require the injectors and fuel to really work to its fullest potential. IMHO start with the fuel upgrades (I imagine you mean a new pump with pre and post filters, filter bowl delete, regulated return) then do injectors, finally do the turbo. big enough injectors will require a HPOP upgrade.

Id do a set of 170cc or 190cc injectors and do an adrenaline HPOP. If you wanted to do a little turbo work now i would maybe look into a wicked wheel to help move some more air.

Thanks guys. That will give me an area to start in sounds like getting more fuel to the engine then I can work on pushing some more air in there.

Dont forget the head studs and an Airdog! Lol! The list is never ending! I love these trucks but they tend to have a snowball effect. :c:

Thats for sure all depends on how much you want to spend. I was looking at an Air Dog, do the filters and and pre pump make that much difference or is worth going for the one that replaces the pump? I have also read about the Powdered Metal Rods that start breaking around 450 HP. Am I getting close to that mark with the few mods I have?

Not there yet, but some injectors and a big ol turbo will put you right there. Its all about how you drive it, you want to romp on it all the time, then yeah your going to have issues, but if you drive sensibly and roll into it, it'll last last a long time with no trouble. Just as worrysome as the rods will be the tranny. But we digress

Air dog is nice, but for a little more you can have a full from oversized pickup to return system with pre and post pump and a pump that can keep 65+psi even on huge injectors, and a regulator meant for diesel.

When you switch to single shot injectors is that just getting a custom tune for it or are there actual parts in the injector that have to be changed? I was looking around and saw that you could put T444E injectors in a 7.3 and that they were single shot. Is that True and does it work good?

single shot injectors is a whole different injector, and you do have to get custom tunes for them, make sure when you are getting tunes from someone (i prefer PHP) tell them you have single shot inejectors and what cc of fuel they flow for example 180cc single shot injectors

Would injectors from a DT408 or 466 work?

i have heard they do work but i've also heard that the cost/benefit just isn't there, never been around them or anything just what i've heard

Injectors from a 466 are typically 250cc ish "B codes"... While they will bolt right in, there is definitely enough fuel in a B code to ventilate the bottom of the block with a PMR motor.

And before you spend money on a full fuel system, decide what your end power goal is.

Stock fuel system, completely stock system, will support up to a 238cc injector. If you're never planning to go bigger than that, then install a regulated return and be done with it.

Head studs aren't really needed until you get over a 200cc injector either, with proper tuning. Improper tuning, or to much backpressure from a poorly chosen turbo will lift the heads right off with a 238, and can do it with less fuel, depending.

With your truck, I'd probably lean toward some 160cc injectors with a stock nozzle, or maybe a 100% nozzle if you're willing to push the limit a little. My 02 has been going strong for the last 25k or so with 160's in it.

I make the engine work pretty hard too. Try to keep it under 3700 RPM's though.
