Engine/Transmission (1994 - 1998) HX 35/40 How do you like it?

[Signal73]

I was looking at a 35/40 Hybrid for my setup below. Thats about as far as Im gonna go for a while (right :-laf ) And right now feel under turbo'ed for the mods I currently have. HTT said 35/40 was probably the way to go and am just asking for some feedback as to how this turbo worked out for you, also any other suggestions would be appreciated



Thanks, Jim

Jim,

I had one on my old 97 truck,it preformed good for me. It is an HTT Hx35/40 stage III. I thought it spooled as good as the stocker if not better. There were no lag issues. If you have any other questions just ask. I did not get a chance to dyno with this turbo, power level in my sig was with stock turbo.

Another option is the Dodgezilla from City Diesel. I ran one for 2 years on my truck and it was excellent. Give Jason a call and let him know what your goal is and he will steer you in the right direction.

I have a homebuilt stage II. Spoolup is like the stocker. Made a huge improvement in EGT reduction, and gave me about 40 hp on the dyno. I'm happy with it.

Jim,



I have the HTT stage 3 set up. We'll have to go for a ride. Very quick spool up with a stock exhaust housing - plus it'll make a great top turbo for a set of twins.

That's what I was thinking.

What did it do for you guys about 200° on EGT reduction? It all sounds good so far. They offer a 16 NWG housing or a 14 WG housing. Im guessing the 14WG would be safer with the stock Head gasket? Paul Ill defenetly take ya up on that offer also. Ill be around fri if you will be in Derby.

Thanks, Jim.

Bump to the top

 

[Rams-n-Hogs]

I run the 16cm non-wastegated housing. The 14 would probably be safer, but i don't hammer on it all the time, anyway. I'd say about 200* reduction in EGT's.

[Signal73]

Hey EE thanks for the bump, Rams & hogs, So if you go NWG housing, you want to watch the boost gauge alot closer I assume, also what boost level do these self destruct at? (35/40) are they tougher then the regular Holset 40's that I read are are good til about 40psi then boom?

HTT vs Piers 35/40

How does the Piers 35/40 compare with this HTT 35/40 stage III? I did not see any information about a stage III on the HTT website.



Thanks

 

[Rams-n-Hogs]

The hybrid on my truck is still the original HX-35 bearing housing, and shaft, with 128000 miles on it. It's been hybrid since about 80,000. I'm not sure where it self-destructs at, cause I haven't done it, yet. I have, however, seen it hit 45, before I got scared and backed out of it. It got there, quick, too. It's great for an everyday driver, that doesn't get hammered on all the time. It also works well for towing, but if you don't have a valet switch, you will need to watch your EGT's pulling a grade, if your pushing a lot of fuel. I can't say how it compares to Pier's hybrid. I'm relatively sure Piers is better than mine, since mine is home built, (cause I'm cheap) :-laf , and I like to be able to say, "I built it myself. "



To read about the stage III, go to HTT's website, click on diesel performance, click on dodge, scroll down to compressor and wheel upgrades, and click on that. Hope this helps.

I like mine with the 21 housing it's a bit laggy but it works

 

[DProehl]

I did the same as Jim but went to the larger overall diameter inducer wheel like the stage III HTT set up, it works real well and really lowered the EGT's, it gets up to 45 lbs boost real quick with my set up. I got all the parts from Rocky mountain turbo and machined the center section myself, like Jim I like to say I built it myself. Good luck on your quest

 

[JPittinger]

DP- What did you use to machine it? I have a large rotary table for my Bridgeport, do you think it would work? Thanks, JJ

 

[DWitcher]

Back to the top. Need more info DP.

 

[DProehl]

I turned it between centers on my lathe, it worked good ,I think I had to take off about 60 thoasands off of each side, Im not sure about using a mill, maybe someone else could chime in on this method, good luck!

 

[vssman]

J'



Using the rotary table is a matter if clamping the center section and clearing the shaft. The end mill will have to stick out a bit but my quick guess is it should clear.

 

[DWitcher]

Great! Thanks for the info. I'll have to give it a try.

hx 35/40 less durable?

Does this upgrade to the larger (hx40?) pinwheel have more considerable rotating mass than the stock pinwheel. Cause the stock hx35 is one tough

turbo and has taken some serious abuse without any trouble. I have read on here in the past that the hx40 was prone to shaft breakage if abused (read barked) or whatever. I also read that the shaft on the 35 was larger and/or stronger than the 40. Just looking for input, was also considering the htt stage 3

to cool the soon to have 370's. Thanks
