I guess in the grand scheme of things though, that statement isn't entirely true. I only get about 2 milliseconds of actual "spray time" with my truck at the moment because my high pressure oil pump can't supply enough oil for more injector on-time (read: not really injecting the full capacity of fuel). The truck WILL smoke like a freight train (as evidenced in the first "all-out" dyno run I did with it) but it's horribly inefficient.

What size nozzles Cody, kinda wondering what would be good for mine with the stock turbo

[cleatus12r]

With a stock truck that's used for working/towing...stick with stock size nozzles. The ones I have on my truck currently are 100% over stock (hafta see how the truck tows 13-15K lbs. when I get home). I have a feeling it's going to suck.

I betcha its gonna be good once the tuning is right....not saying it isnt already....but mine towed real nice once they were dialed in.

[cleatus12r]

I'm not worried about the tuning. It's about dead-nuts now.

It's just the wonderful world of taking the reliability of a stock truck and modifying it......

You know what I'm talking about.

[907DAVE]

That's why my single cab is staying stock.....I dont want to even open the hood unless its for an oil change.

And watching the gauges like a hawk is not much fun either.

[cleatus12r]

That's why my 95 is staying stock.

I purchased this 2000 to be a "toy" anyway. A toy with a gooseneck ball in the bed.

Thanks Cody, so the single shot w/stock nozzles is what I should be looking for

[cleatus12r]

That's what I recommend for everyone in your shoes, CJ.

On paper, the Stage 2 injectors 160/80 or 100% nozzles just aren't worth the trouble. You're either shooting for good numbers on stock high pressure oil (like the 160/0% injectors in Bill's red truck; 395 HP and still able to maintain 3000 PSI) for $1100 or you're looking at making more than 400 HP with the possibility of not needing an aftermarket high pressure pump (strong case for hybrids).

Stage 2's are just kind of....well.... outdated. They're pretty oil hungry and they don't have the fuel capacity for an easy 400+ HP.

Thanks Cody, the reliability is really what I'm after & the way I drive I've got plenty of power. I'm just trying to get a good idea of what I want to do as I've got 190k on the originals & I believe a couple are a little sticky.
