Need injector education - 175/146 vs hybrids

Sorry in advance for my injector ignorance. I am thinking down the road a little bit here and was curious what injector would be the appropriate upgrade. Here are a few of my thoughts, in no particular order:

I would like good fuel economy- I currently get 18.5, hand calculated at 70mph.
I do not want the truck to be abnoxiously loud - I am not sure if one injector is quieter than the other.

The truck needs to be daily driver quality.

I did not want to have to upgrade the turbo, but not solid on this decision.

I don't think I would be interested in anything over 400hp.

I have pmrs right now and if I keep the stock injectors, the rods will stay, but if I upgrade injectors the rods may have to go.

To be honest, I am not even sure what hybrids are. I am aware that one of the great advantages is that you may not need big oil.

The 175/146 split sounds perfect for you.

I asked specifically about that injector and the response I got was that "it takes so much more HPO to operate than the 175/146 single shot that it was not really worth it." I am in a very similar boat as clydesdale and have eyeballed these 175/146 splits many times. The price is right too!

Singles are more efficent, in many ways. If you ran 175 singles with the right tuning there'd be no reason to crack your bottom end, or do anything else to the motor.

Re: Need injector education - 175/146 vs hybrids

I can't think of any good reason to run splits personally.

Worse MPG
Worse Power
Worse HPOP useage
Maybe a tad more quiet but negligible.

Don't do 175 splits!! Either 175 singles or 200 hybrids, the Hybrids won't need an HPOP upgrade to make 400+hp

Re: Need injector education - 175/146 vs hybrids

The 175/146 injectors that I am thinking of are singles. Is there a reason or advantage to go with a mild hybrid, if there even is such a thing? Can the hybrids be tunes down to the equivalent of the 175/146 and thereby allowing some room to grow up with a little more tuning?

Yes and yes, the smaller hybrids use less high pressure oil volume than stock AD's.

Re: Need injector education - 175/146 vs hybrids

Both injectors would be great for your setup. The hybrids will use less oil. With either injector, if you are staying with the stock turbo and will be spending much time in the hotter tunes, I would recommend a larger exhaust housing, either the 1.0 or 1.15. And I would delete the ebpv for more flow, lowere egt and less drive pressure. That would be the makings of a great pmr motor! I vote 200cc hybrids and 1.15ex and have Bill retune it!

Re: Need injector education - 175/146 vs hybrids

I would go with a set of standard 235cc hybrids with 80% nozzles...

With good tuning it should net you the same MPG and what ever power you want to stop at...
