Engine/Transmission (1998.5 - 2002) Need a new turbo ASAP!!

[Beach]

I need some serious advise as to what I should do for a replacement turbo! I was taking a buddy out for a ride and beating on it when it seemed the power started to fade. I let off and that's when the turbo was making a loud whining sound like the turbo "fin's" were rubbing. Not a good sound. I limped it back to his house and pulled the intake tube off the turbo and there is a little more play in the shaft than before! I've been dreading this for a while since my turbo is golden and been pretty much roasted from to much fuel! I need this truck back on the road since it's my daily driver. I just got it back running again after breaking the input shaft. I had to send the tran's out to ATS in Col. and the truck was out for a month. I just got it back together on the 4th and now this. I am going to have to sell my 4-wheeler to pay for a new turbo! I need some help in choosing the right one for the right price and application! I need something that's going to drop EGT's pretty good but spool's like my HY35 or better. I don't want to spend an arm and a leg! I don't need to much more horse power but it would be cool. Looking at my truck profile, I'm guessing I need headstud's also! I'm thinking of these turbo's, but don't know much about them: 1. ATS Aurora 2000. 2. Edge Jammer BB. 3. BD's single? 4. Schwitzer? 5. Quadzilla? 6. HX40? The ? mark's are one's I have no clue about, just heard of! Sorry this is so long but I need serious help fast! Thank's for any direction!

If I had the HTT rebuilt already, I'd sell you my PDR 40. I'd bring it out and help install it too. You're only about 100 miles from me.



Have you looked in the TDR classifieds yet? Might find a good used one. Either the PDR 40 or a HTB2/12 would probably work just fine.

I've got a Dodgezilla 35/40 hybrid with about 700 miles on it that i bought for a wastgate project. I'd sell it pretty cheap. It's been wastegated at 25lbs in my twins so it's basicly like new, but broken in.

Thank's guy's, I'm kind of leaning toward the BDsuper B and a set of head stud's. Sound's like a direct bolt up and decent price. I'm still open to opinion's though! Thank's! The hardest part is coming up with the extra money!

That DZ 35/40 sounds like a good deal to me. It'll move much more air than your old HY 35 & even a new one will cost you much less than the options you're looking at, probably spool quicker too.

 

[AKAMAC]

I have my old HY that you could use till money became easy again. I could leave it out tomorrow for ups pick-up if you need. I'm not worried about damage to it as I won't need it again. You just pay shipping. Mike

Hey RonA, can you tell me a little more about the Dodgezilla! Will that work on my '01. I see you have a 92 or is that not the truck it was on? I'd like something that will push more air, drop EGT's, a little(or a lot) more horse/torque, and bolt up using my down pipe I have now! It's flared w/ two bolt's holding it, no clamp's! Will it work? Send me a PM w/ a price if you want! Thank's

Beach, I've run a DZ 14 on my 01. 5 with Mach 3. 8's an APB & a Smarty. You are pushing it's limits fuelled like we are but it works pretty good in the low lands but it could ge a little warm on a long mountain pull. On the other hand, it spools very fast & it's great in traffic.

 

[Beach]

I don't want to push the limit's on any turbo again! :-laf I just want to have plenty of reliable power and not break thing's anymore! I love my truck and would lose my a?? if I tried to sell it with the money I have in it, but it has crossed my mind recently. My buddy is friend's with a diesel mechanic that said he could get me a HX40 or HX50 hybrid but I don't know anything about either. What is a hybrid turbo? I'm trying to learn about turbo's over night so I don't buy the wrong thing! Thank's

I believe the DZ 35 40 is a tougher unit than the HX 40 but it doesn't move as much air at the top end. You won't hurt the turbo. Wastegated to 38 psi it's quite efficient. The hybrid just means it's made of parts from two different sized units. The DZ 35 40 has the turbine wheel of the HX 35 & the compressor of the HX 40.

Who make's the Dodgezilla and do places take old turbo's as core's or do they become paper weight's? I'm so confused with all these choices! My biggest concern is keeping my EGT's way down and having a good power curve! I think the high EGT's are what took mine out! I could peg my pyro in 3-5 second's! My TST box would actually read "TO HOT" so I don't know what temp it was at after a while! Not good obviously!

 

[RonA]

My 92 has a p-pump converted 2002 motor in it. The DZ is a step up from where you are, but if you are over 375hp, you will still be able to go over 1300 deg easily with everything turned up. Mine is set up for twins right now with a rather large wastegate mounted to the 14cm n/wg housing. It would probably just be a band-aid for your egt issues.

 

[PC12Driver]

If you're wanting to keep your spoolup, I don't think you'd be to happy with the DZ/14. Especially since you have a tight auto. It spools great with enough fuel and rpms, but then again which turbo doesn't? Off the line and around town when you're not fueling heavy it'd be laggy with your auto. I sold mine for a High Tech Turbo HTB2/12, which made a night-and-day difference with how the truck performed. The new turbo wakes up much sooner and keeps things cooler with less psi than the DZ. The DZ has a "hook" when it wakes up, where the HTB2 starts pulling sooner and smoothly transitions to the top end. And it has a real wastegate that vents all six cylinders, so drive pressure stays nice and balanced (which means you can get away with running the smaller 12cm housing and keep some spoolup).



With 465hp, I've yet to see 1350* with my combo. I do have a cam that is good for 50-100*, but I am also only pushing ~32psi of boost. The HTB2 can make "good" boost to a little over 40psi, so I could cool things off a bit if I turned up the 'gate.



The HTB2 was well worth the extra $. After my experience with a Schwitzer-based turbo (like the HTTs, or BDs), I'll never put another Holset on my truck.

 

[zstroken]

I am with PC12Driver. My truck can get a little warm with the box on, but is easy to keep under control with the box off dragging around 13K.

 

[Beach]

I think I'm getting closer to what I want, "I think". I've narrowed it down to the HTB2 or the BD Super B I think it's called. The super B is suppesed to bolt right up and I can use my existing 4" down pipe. I need to do some more reading on both and a couple other's possibly. I dynoed early june and had around 355hp/755tq. Would those two be good for my set up and power. Also, how much more do turbo's usually give!

 

[PC12Driver]

I can already feel the backlash from this one, but here goes...



I think the HTB2 would be too big for your current HP level. I spaced and didn't check out your mods when I suggested it. At that power level I'd think something like a HTBG or similar would do you just fine. If you get a bigger turbo than you need you'll just end up with unnecessary lag. A stock HX35/12 is good for about 350hp, so you probably don't want to get much larger than that. With High Tech Turbo's trade up program, you can start with what fits your truck now (I'd say an HTBG/12) and upgrade the components for a fair price as your needs grow. The 'BG/12 will last you to about 430hp-ish. I believe the Super-B has a larger exhaust housing, which you don't need at that power level.



Don't think of the turbo as a hp upgrade. Fuel is what makes power, air keeps the egts down. You may gain a few hp from a more free-flowing turbo, but egt reduction is where it's at. And keep in mind, too large of a turbo can cause a loss of power (ecm doesn't send fuel 'till it sees boost; if boost takes too long to build then fuel doesn't get added 'till later in the rpm curve). The turbo "shapes" the power output of our engines kinda like a cam in a gasser. Figure out where power is important to you in the rpm band and pick the turbo/housing accordingly.

 

[24V-DSL]

No backlash here... . I agree with you. Good info post.

 

[Beach]

I'm glad you said that. The HTBG is cheaper and I like the fact that I can upgrade if I need to. What are your thought's on the BD super B. I can bolt that one right up using my down pipe. The only thing that bother's me is that my down pipe is 3. 5 at the flange and jump's up to 4" right away. Should I get a true 4" or is what I have O. K. for egt's. The lower the better. I just want to do it right and not put a turbo on only to find my down pipe is still a problem!

 

[JR2]

Why don't you just get that free HY35 mentioned above and take it easy for a while. That way you could learn about all the options and make a good unrushed chioce.
