Engine/Transmission (1994 - 1998) just lost turbo help

[DDarmos]

turbo started sounding weird. took the intake hose of an turbine inside was loose and I could see wear on the inside around where the finns were rubbing. The trucks has been running great before that. I would like to have equal or better power. The turbo was factory original with 190,000 on it and max boosting 47-48lbs. I have removed the fuel plate, tightened the governor spring, pluged wastegate and made a airbox with an afe aircleaner. Plus a straight pipe that goes from factory to 4" under front seat. Truck is 5-spd, 4. 10 gears, and luk pro gold clutch. Just made the air box like afe last week it has dropped my fuel mileage :--) ,but dropped egts. I plan on timing truck at 15. 5 to 16. 5 not sure yet and a 4000 gov kit. what turbo do you recomend I look beating on it an puttin down powerstrokes, I am runnin low 15's in the 1/4mile. limited budget want new or lite use. is th hx-40 the answer or ?, what do you recomend.

thank you for the help, need to be back on the road soon

wow!

wow 47-48 psi :--) . im suprised you turbo lasted that long. thats way too much boost for the stock turbo, generaly the hx35 moves out of its efficency range at about 35-37psi. the tubo is already spinng fast enough, and i cant even imagine 48psi on that turbo. a pdr hx40 would be a good upgrade. any hybrid turbo would be good. theres been good succes with the htb2 turbo from htturbo. the only thing is do you want to sacrifice some spool up for more top end, or have better spool up ,and not so great top end. either way you need a turbo witha larger compressor, which flows more air. sorry to hear about your turbo go, but 190,000 is a pretty good number for a stock turbo.

what is my stock turbo hx 35 with ? cm housing

 

[Bob4x4]

12 cm

[DDarmos]

If I go with a hx 40 what cm would be recommended. I see piers has different sizes and the 18 spools like a 16 and 16 like a 14 . Any suggestion I would like it to spool rater quick but I don't am still learning what is best.

 

[SEmerson]

HX 40 18 should work well for you. And you can add a HT3B to it later to make a twin setup.

 

[Joseph Donnelly]

The Diesel Dynamics jammer turbo spools very well and is more durable than the HX40s. Costs more, but it lasts much longer in hopped up Rams. I have blown several 40s and chose the Jammer for my 2004.

 

[CATCRACKER]

i think greg b popped his jammer on his 03 maybe he will see and correct me if i am wrong

 

[DDarmos]

I have looking at DD jammmerand piers hx-40. Not sure which would be best. A friend of mine said that the boost gauge reading is different with the hx-35 than the hx-40. Something as to the effect the with the 40 at 40lbs is more (air ?, not sure what he is talking about, maybe harder on the head gasket?, don't know) than the 35 at 40lbs. I figure if I am replacing the turbo I should up grade, I love to run the truck hard. So which is better in power, durability, an lifespan the piers 40 or the jammer. Will my truck run quicker with the turbos I know I was gettin some high boost #'s. and I would bury the egt gauge in 4th gear until I made that air box.

Thanks for the help

more air with the hx40

i may be wrong about this but ill giveit a try. the hx35 can put out 40psi, but the compressor has moved out of its efficency range, thus all the turbo is doing is blowing alot of hot air, hot air = less power. a hx40 can put out 40psi, but the compressor map on the 40 is higher, therefore it is making a cooler 40psi than the hx35. at the same time the larger compressor is moving more air, or in other words the hx40 is flowing more air than the hx35 could do at the same psi. even though it is flowing more air, the over all pressure on the head gasket has not changed. at the same time, you have a larger exhaust housing on the hx40,(16cm2 wastegated vs. 12cm2 wategated) and that will create less back pressure, and the engine will not have to work as hard to expell the exhaust gas through the turbo making even more hp. clear as mud? experts if im wrong feel free to step in!

if you run an HX40, run a 16cm housing

45 psi

"i may be wrong about this but ill giveit a try. the hx35 can put out 40psi, but the compressor has moved out of its efficency range, thus all the turbo is doing is blowing alot of hot air, hot air = less power. "



Glad I came by this thread. That is interesting to know.

My stock turbo is making right about 45psi with plugged wastedgate. I have been looking at new turbos as well as I plan on moving up to injectors and delivery valves.

Would I be in the same boat as DDarmos? I eventually would like to move up to twins.

 

[WDimig]

trqmonster - id be very leary to push the stock turbo past 38psi for long. look for a good hybrid turbo for you choice, or if you plan on going big, twins would be an excellent option.

which turbo is better

I also will eventually upgrade to needing twins, but not yet $$, so which turbo would be better piers hx-40 or dd jammmer. which is heavier duty. Hey trqmonster I was at tere haute this year "good" time, but I thought it would be wilder, police were strict.

 

[WDimig]

ddarmos - id go with the jammer. a bit stronger than the hx40 and as far as i now they flow near the same amount of air

 

[TrqMonster]

I am not really expecting the stock turbo to last long. I just blew the head gasket a couple weeks ago and its getting fireringed and studded and some other goodies at Scheids right now.



Yeah, the extravaganza was kind of toned down becasue of the popo. I think Muncie was a lot more wild. I guess people didnt like all the smoke.

 

[DDarmos]

muncie

ya I was at muncie it was a blast. I also go to lima ohio 4wheel jamboree it gets pretty wild there. ya the popo broke up or party at tere haute for burnin tires. I am still undecided on which turbo dd jammmer or piers hx-40 what have you found since you are looking to upgrade?

 

[TrqMonster]

Either the HX-40 or the B-1, but if I went with a B-1 its almost the halfway to a set of twins which I cant afford right now. Where do you get info for the DD jammer?

I am going to talk to Scheid when I pick my truck up and see what Dan Scheid says. I will be upgrading my injectors and DV's and will need a better turbo. Still waiting on my truck though as they need to cut the grooves for the o-rings. It will be worth the wait.

Bring on the boost.

Do you have a stock clutch?

today i talked with diesel dynamics and piers. diesel dynamics really turned me off and was not helpfull at all other than eliminating them by not wanting to give me any advise or answer my questions like "what is max boost+what we set wastegate at= your not answering my question" :-{} on the other hand piers was very nice said the hx-40 was not what I needed and the b-1-2 ex4 would be teh best for my truck and what I have planned in the future. bigger shaft on turbine =longer life. same question as before"what is max boost50+ + but we recomend wastegate at 40 for your head gasket= thank you for the advice. sounds like the b-1 is the choice little more than i wanted to spend, but it will not become obsolete and have to be sold at half price for me to upgrade again, it will just be half of a twin. Oh no stock clutch I am running a Luk pro gold for $350 holds since april talk to a rep at muncie an he said there were truck with more than the 700ft/lbs of torque running it, he see confident it could hold well for a single disk. If this goes mcloud will be next.

 

[TrqMonster]

Yeah, I didnt see it in your post. I had a #11 plate all the way up and it would slip the clutch bad. Put in a $400 button clutch from a local guy. It holds great. Same here though if it goes Im getting the street puller (what I wanted in the first place). Exspensive but oh well. Also would need new input shaft.

so the B-1 can be used them in the future for a twin setup? I guess that would be ok as far as justifying the price, which was around $1500 or so I think?
