Okay so I kind of started this discussion with Mr. Beggs on another thread but thought I would bring it to the front. I am actually thinking of going this route since they can be tuned to any lower level (Stage I, II, stock) but can also be tuned for extreme or Wild. From what I read, you can still run your stock HPOP with them which is a savings in itself(I have a 17* ready to install anyway) but would require a better turbo eventually. I plan on putting in a D66 turbo at the same time. Will this be enough. Is anyone out there running these in there Truck. How do they like them? I really drive like a grandma and I dont care about laying a mile long trail of rubber or blowing a Cummins away BUT I do like knowing i have 450 RWHP at my discretion. You know its that guy thing....bigger ,better, longer, faster.etc. Any and all input, opinions, experiences, knowlege, tall tales would be appreciated.

Sorry, I forgot to ask about the hole thing. What about the larger 7 hole nozzle's verses the old 5 hole. The claim is the 7 hole are 80% larger. What does this equate to?
PowerStroke 7.3 Injectors

Well?

 

Other then two more holes of couse!! Am I talking to myself(lol) Maybe Ill come up with a tall tale.....

 

The 7 hole nozzles are the PSD nozzle. the 5 hole nozzles are for the 466 and 530. They are just new as in brand new from the factory with larger holes not enlarged afterwards. The D66 isn't recommended for injectors bigger than 2's. There are a few running it with hybrids but its not optimal. An H2E would be the turbo to go with.

 

TJ, Can you lend me some money for that H2E? (lol) Is the H2E a direct bolt on? If your not running in tahe extreme mode much does the D66 still fall short?

 

I would expect the D66 to fail. it's only rated for 40 psi, and IMO hybrids would go way past that if you let them.
With the larger nozzles, you cant quite expect the same fuel economy, because unless you're running WOT, you dont get the same atomization. I have heard of staying close to 16-17 with them, but any more than that i'd have a hard time believing.
As for a budget option for the turbo, i'd look into the HX50 if you have any fabrication experience. I think TJ's trying to do one for under $500...

 

Sorry I have my own addiction to finance! The Holset H2E is not a direct bolt on but it can be with a kit to the tune of $2500. Or you can build you own mounting kit. Like Secondarychaos said that is my plan with a Holset HX50 (similar to H2E). Should be under $500 but I bought the turbo for $150 and need to rebuild it then build the mount, up-pipes, intake and down pipe.

 

will the d66 work with the stage II injectors. what boost will i (or aireeek) be seeing with that setup? should i (him) be worried about headstuds?

 

With two's and a d66, i'd think you could hit 50psi, with the right intake and exhaust. I'd be worried about headstuds, and gaskets, ya, but im really not sure that the D66 would hold up to that kind of punishment.
I, however, dont have first hand experience. only what i've read and what the site says.

 

yes the D66 is recommended for 2's and below. Boost don't know. close to 40 psi I would guess.

 

So Im still alittle confused. If I put in stage 3's and I never used them for more than stock, stage I or stage II levels but always had the option to upgrade stuff later for stage 3's, would this still ruin my D66 turbo? I mean, I know it sounds stupid to invest in stage threes and never use them to there full potential, but It provides the options to upgrade later and not have to change my injectors. It seems like a good idea that you can run with stage I's when towing, stage twos whem hot ******* and stage threes when you race are or just pissed at your girlfriend and just want to spin your tires to show her(yeah, right!). Is it the constant more fuel that the injectors are supplying that ruin the turbo are cutting the setting up to high which delivers more fuel than your turbo can handle tha ruin it??

The key to the D66 is not exceeded 40 psi. So do that and you should be fine. You can probably even go over that a few times just not extended.

 

With my new stage II's I am seeing Easy 32 psi and often 35 psi and I still haven't run the air out of the oil system yet. I would seriously look into H2E or HX50 mod. You will be surprised at how easy it is to get well over 30 psi boost when speeding up to get on interstate etc.
