Hi and welcome to the forum!! I'm Rykan one of the owners of Holderdown performance. For not much towing and wanting some power I'd go with the 64mm turbo and bigger than stock nozzels such as 75% for sure. The big price diffrence comes from the new performance cut nozzels. They are not just extrude honed like some. The bigger nozzle will empty the injector of fuel faster. Therefor in the upper end of your rpm range you can inject your fuel in the prime spot (piston bowl) for the most power. Hope this helps!

 

Do you think 190cc injectors will be too big? How streetable will this set up be?
Will I have alot of turbo lag?

 

I run 190's and a 65mm Vgt daily on my truck. Obviously a 64mm non Vgt will have some more lag but that's all in the sizing of the exhaust wheel and the housing. It can be made real streetable. Tuning plays a big role as well.

 

Will an S366 be to big? I do not want the lag to be extremely bad. What a/r do you recommend on a s364?

 

I'm getting ready to try an s366 on my 190's I'll let you know how it goes. But alot of people who I've seen that run a 64 run a .70 housing and seen to like it.

 

first you want a 62mm or 64mm then you bring up 66mm?

i'd say 190/75 and a 64/71/70 would be a decently quick street setup and an okay >8k towing setup...

these threads are getting old.. what happened to trial and error:doh:

send me your credit card and ill build your truck for you... this is what i told a customer after he handed me a heated fass system, an aurora 4000 and 225cc injectors to install on his truck... needless to say he got his truck back with a much different setup and I have a shelf full of parts to sell.

 

Guys need to use the search bar to see if anyone has asked the same question. But on a side note wana sell those 225's oke: ?

 

I see those threads, but they can't seem to stick to one turbo..

 

I just want to know what turbo to get 550Hp!... And I do not want the powermax or alot of turbo lag.

I plan on changing the injectors out, I'm working on a 2 piece billet intake, and im ganna port the heads.

 

Don't waste ur money porting the heads...... it wont be worth the cost at the HP level ur looking at...... 64mm Turbo 190/75% tune it delete it beat on it

 

a 62/70 will bring you 550 with the 190/100s on a race tune...

haha two piece billet intake? have fun with that

ported heads? worthless

troll?

 

all our cnc machines are sitting idle in this economy anyways. haha hopefully i could come out with something sweet that other people might want. i could already see me cad designers giving me the stink eye

 

good luck!

 

if you go with the 62mm id look in to the batmowheel will help with the spool up 66mm is going to be way to big with 190 or small just my two cents

 

a 66 will be just fine for 190/100's, depending how you spec it, it will spool quickly

 

this is about the 442 thread about "what do I need to make 550 hp." search my brotha....search.

 

Don't you own your own diesel shop ??

 

Where is the best place to buy 190cc injectors that won't brake the bank

 

I have 07 f250 6.0 I want to upgrade turbo and injectors trying to get 700hp so far the injectors are going to be very expensive just looking for the best place to get them without getting a loan for it lol

 

In order to have a truck that makes 700hp reliably, your going to be in your truck $15k at the least. What mods do you currently have?

 

You want 700hp but don't want it to get expensive? Injectors aren't your only but expense. But you can't expect to cheap out and have reliability either. If I'm buying that big of an injector (it'll take a big one to get that 700 number), I sure as hell don't want to go cheap. Ben then there's the issue of turbo, which will cost you 3/4 the price of those injectors, more than likely dual HPOP (which ain't cheap), fuel system, built trans (another $5k)....see where this is going? "Being in it $15k at least" is 100% accurate.

Now let's talk about everyday usefulness of the truck. Forget ever towing again with that setup, and I'd imagine it's not going to be the most pleasant daily driver. But if this truck is just a toy, and nit your primary means of transportation, have at it. Just don't expect it to be cheap.

 

Just realized you dug this thread up from 2011...And how big of an azzhat some members were back then!

 

You better have deep pockets and be committed to go all in and do it right if you want a reliable high power daily driver truck. Trust me I know from experience.

 

I think we scared him off

 

Building a high hp 6.0 is a lot like dating the hot chick. You get all excited at first, thinking it's going to be a blast, but soon realize it costs WAY more than its even worth.

Usually only takes a few posts with dollars and cents thrown out there in them to scare most off.

 

Yeah but when it all said and done and built it's bad ass to have and a blast to drive.

 

I don't doubt that at all, but most people don't have the time, expertise, or funds to upkeep/maintain/own one over 600hp.

 

I think a lot of people get caught up in the internet hype of what they think they should have. One should do their research pretty well before settling on a setup for their vehicle.

 

I blame YouTube. People,watch a video of a truck running hard, owners says "it's just got injectors and turbo", and people say to themselves "I can make that happen". They don't know about all the other supporting additions it takes to make those "injectors and turbo" reliable.

 

More than that my friend. These sites as well. I presume a lot of people probably aren't 100% honest about their set ups or have an actual clue what hp they are actually putting out.
