right now with the fuel i am running my h1c with 60mm wheel is to small. has anyone ran an hx40 of these trucks? i am also thinking about putting an intercooler on my truck but that is later on. i just thought about going to a couple semi truck junkyarks around home and try to find a good hx40 on a truck. what i did not know if that would be any improvment. the 60mm wheel is doing ok for me but i dont trust pushing much boost out of the h1c, or should i start saving my pennies and get a good aftermarket turbo? i aint sure what to do.

I'm in the same situation myself. Too bad air is so expensive.

Most junkyard turbos have too big of an exhaust housing. You are better off buying a turbo set up for a 5.9. I wouldn't bother with an HX-40, I suggest you go straight to an HTB2. It's a much tougher turbo and can make more boost.

that is kinda i figured you would say and you are right air is really expensive

Twin it...I've got a set of those you could test drive too

i dont really want to do twins i want to make big power on a single no drugs yet at least yet. i dunno i think twins are sweet but i want to do what i can with a big single.

Then skip the HX40 and go straight to a big single.

Don't mean to steal the thread but what size of exh housing would you use with the HTB2, would a 16 be too big?

I'm running a 12 on my h2b2, spools nice n quick. I wanted a 14 and he talked me into the 12 instead I'm glad I listened. My $0.02 Jethrro

rockjeep73

are you talking about wastegated housings? if so a 16 would be too big, I would have to agree with Jethrro on the 12.

with a nice 2nd gen IC you would drop you IAT's ALOT, making the intake air much more dense. So you could see a little lower boost and make more power. I dont think you can make huge safe power without an IC anyway, so why not spend the $200-300 now and put one on. The H1C with 60mm wheel and high AR is good for an easy 350 rwhp at around 35psi. I may not know diesels as well as i know gassers, but in know turbo's and there potential. What is your end goal for power and reliability? Might as well buy it right the first time and save alot of head ache. LOL

Sounds like he's asking for CHEAP. He's not wanting to buy a new or vendor hx40, if he had that money, then yes, a HTB2 or B1 would be the wiser choice. For CHEAP, aka junkyard, if you can find a hx40 with a 16 or 18cm housing, the 16 being the more desireable and harder to find housing, and get it for less than $200, I say jump on it. Of course if its in decent shape, and ready to put on a truck and run.

Underpsi, the HTB2's come with their own style exhaust housing in either 12 or 14cm. You can't use a h1c or hx35 housing with one, without major work I imagine. It's a whole turbo and housing.

IHP, I used to feel the way you do now about twins. Thats when I was just didn't understand the twin concept. I suggest getting that 'gotta do it with a single' idea out of your head as I have done now. Who cares how many turbo's you have lol. It's all about air and fuel. I mean, spool up of a itty bitty turbo/housing and air flow of a big turbo?? Who wouldn't want such a thing???

Definately go to those big truck junk yards and see what you can find on engines of 10L and less. Usually can get a good runner for CHEAP. Have some fun with it before you save your pennies up for a super duper vendor setup. Or you might end up satisfied with your el cheapo junkyard turbo, and can laugh at all the guys like myself that spent high dollar on a vendor turbo, when you bought a similar turbo that might do the same job for hardly nothing....

Underpsi

So you wouldn't use a non wastegated housing with a HTB2 then right? I always thought 12cm was bad for exh restriction.

bgilbert

The HTB2 doesn't come with a non-wg housing. It has a true 4" exhaust housing, its not the same as a hx35 3" exhaust housing, so it will flow more air.

I'm wondering if there is a CHEAP way for all of us HTT stage 4 guys to do twin turbo's. Now i think the HTT stage 4 as a top turbo wold be fine and a ???? for a bottom turbo. What could we get from the junkyard that would be a good bottom turbo?

Thanks

The HT3B is supposed to be a good match for a hybrid.
