i have a 2006, with smarty jr, air dog 150, snow performance stage 3 water/meth, MBRP exhaust, AFE intake with green filter and a ATS intake horn and a suncoast trans (torque converter, valve body and shafts)... i'm looking at upgrading my turbo... alot of people have told me to look into an HX40 (i think thats what it was).... i have the stock turbo on now and looking to upgrade... i do A LOT of towing, usually 12-15k sometimes as much as 30k (i own a farm and tow 2 bin wagons at a time on occasion)... i want something that will give good power from low to mid to high range... after i turbo i plan on doing 100 hp marine injectors and a CP3 mod of some sort... i have no desire to sled pull or drag my truck so i'm not worried about anything like that... just something that will make good RELIABLE!!!!! power...

thanks
nick

 

Don't, Do not, heavens pleeeese don't think about an hx40.
First, it is old technology and slow to spool for the air it puts out.
Second, it is not a turbo to tow with.
Third, it has a weak shaft that is prone to breakage when pushed and therefore is not "reliable"
Fourth, no way it supports 100hp injectors and a programmer.

You may want to strongly reconsider your desire to use 100hp injectors with the weight you tow... that is a lot of heat that turbos can't necessarily overcome the way you want. With the towing you descirbe and the need for reliability, may I suggest 50hp injectors max. I think I know what injectors you are looking at-- QSB 480 marine nozzles. Please don't let all the Comp D folks steer you into stuff you neither need nor will benefit from. They have the $$$ and truck downtime to swallow. I am sure you don't. I am not entirely sold that the spray angle of the QSB nozzles is entirely compatible with your 06 pistons either.

There is no "magic turbo" that does all you are asking-- everyone wants the do-it-all-and-more turbo; that really does not exist, especially with the activities you have that are mutually exclusive That being towing heavy and often with big injectors. You want to consider twins at this time.

It appears you have a lot of supporting mods and that is a good thing. But what you really want to do now is define your realistic goals and go from there. You aren't going to build a potential for 800 hp truck and tow 30k and expect it to live.

Based upon what looks like your need to have a work/tow truck and not a dyno queen, I would recommend looking at 50hp stix, a towing cam and a s400 under the stock turbo kit.

 

^^^^^^^ yep, I think Soulzoo summed it up!!!!!!!!

 

WOW! thanks a million!!! i did some research on twins using the stock turbo and i think thats the route im going to go... as far as head studs and head gasket, should i address that? like i said, reliability is #1 for me, i can't afford to have my truck down, and would rather address all the issues early, before anything goes wrong... i'm not sure if i want to modify my motor internally... how much boost would twins make using the s400 under the stock turbo?

 

Minus the 100 hp injectors I think a 62/65/13 would be a great setup for towing. I've had mine on for over 60,000 miles and I've yet to turn the juice down from 5 while towing. I've pulled several loads over 15k and the turbo keeps the air in check. I've been very pleased so far..

 

The boost you will see will be relative to the fuel you throw at it. A rule of thumb is about 10hp for every psi of boost on a common rail. So 20 psi boost = 200 HP. That is just a guide and not a absolute and results vary widely. I made 900hp at 74 psi boost for example. On the other hand, I have seen 90 psi of boost on the street. As airflow improves (boost is a measurement of airflow restriction, not how much air you are getting) boost will actually go down while providing the same or more air. A stocker over s475 is capable of just under 60psi with stock components before it is out of the map. Some folks have managed 600hp with that combo. Studs are recommended (again opinions vary, this is mine) at boost levels over 45-50psi. Valve springs are also recommended at that boost level and spinning over 3200 rpm. (Valve float is possible)

Personally... again, reliability being your key here, I would stick with the 50hp stix, stock over s400 tune it to stay at 45psi or lower. You can add studs (say ARP 2000-- 625's not needed) but don't change the head gasket! Do a one for one swap out of bolts to studs. For some reason the factory seal is much better and takes more abuse so it makes sense not to disturb the gasket if you don't have to. And you don't have to.

 

I know you will be happy with stock over s400.. That is what I have and I 1st had a Silver 62 and learned how to drive around the lack of spool. I have not changed my stock stix and still love how the truck drives compared to stock or Silver 62 I had. If I had gone straight to the s400 instead of Silver 62 I would have the 50hp stix by now.. Hoping this spring to do stix and studs and then be able to bring up boost some..
Twins are the answer to a nice driving vehicle.. and power.

 

Don't forget the towing Cam. Until I swapped mine, I didn't know what I was missing.

 

What is the benefit of the towing cam.

 

Quicker spoolup and a wider powerband. More TQ down low.

 

Forgot to change sig after adding Diesel Pro Killer B and Hamilton 110# springs... I had hoped this would also help with my instant black oil changes but it did not help oil.
