I'm getting ready to buy some POD injectors. Along with the PODs, I am also going to be doing more pump mods (internal), tranny/TC mods and getting a larger turbo housing (probably a 14cm WG). I just don't know what turbo or compressor wheel to get. It seems like there are a few options.

1. HTT Stage IV. This is a nice cheap option. Any problems with longevity on this kit? I think I remember seeing that wannadiesel was running one of these in his truck, and said he needs more air to burn the fuel from the PODs. Maybe I am missing something, but

2. PDR HX40. This is the expensive way. Will it give me more air than the HTT stage IV? I searched and it seems as though the PODs have enough fuel to spool this baby up. As for exhaust, I can TIG/MIG/gas/arc weld, so I could fab something up pretty easy, and save me from having to buy a $150 4" downpipe. Is the compressor wheel in this larger than the HTT stage IV?

3. Any other options? I was looking into an HX35 but I thought I read somewhere that you can't upgrade the HX35 as much as you can with an H1C (becuase of the HTT stage IV).

I'd rather spend more money now than have to upgrade my turbo in another few months. Any input is appreciated. Also, this truck is now my play truck, it really won't be used for any towing. I might be totally wrong with all of this, so set me straight!

Oh, and I joined the pull cable club today.

 

I cant see the HX40 being any problem to spool. I use one on my 2.2 liter 4 banger and get 23 psi by 3600. So with 5.9 liters it should be no problem.

 

I'm running a HTT IV/12cm WG, without the internal pump mods wannadiesel has done. Its enough to keep my setup comfortable, it will get alittle warm, but I don't have the plasma hot exhaust temps like I had with the WH1C and H1C I had on.

There have been reports of problems with shafts breaking on the HX40's with its bigger wheels, shaft size isn't any bigger than a HX35 or H1C.

Wannadiesel will probably comment in the morning about this, but at one time I was thinking about getting a HTBG from HTT instead of upgrading the H1C. I think he said he had something close to $900 tied up in that turbo. A HTBG isn't much more than that.

The HX35 is identical to the WH1C in every way except construction, which is why the H1C/WH1C turbos are upgradable to a larger compressor side than the HX35.

 

I thought the Super 40s had the bigger shaft that eliminated shaft problems?

 

Does the PDR HX40 push more air than an H1C with a HTT stage IV? How about the HTT HX40? I don't have a problem spending more money now to get a better turbo... I'd rather do that than having to spend more and upgrade the turbo again in a few months.

 

Im running the HTT H1C with an HX40 compressor and a 16CM housing. It spools very quick and wont cut the power on the top end.
I never tryed the 12 CM wastegated housing, Im sure it will spool a little quicker than my set up but I bet it wont pull in the midrange ond top end like mine does. I was totally satisfied with this turbo untill I ported my head and installed the ATS manifold (which is also ported) Now Im thinking I need a bit more.
Im thinking now about the HT2B or the KSB serious. Maybe twins
I think the HTturbo would be a good update but I heard they were 4 weeks backed up. You might phone them and see what they have to say.
Its all good, have fun!!

 

Don't waste money on the 14 cm WG housing. If you can't keep the boost under control with timing and a 16 or 18.5 cm housing, you need a bigger turbo anyway. In the short time I ran the truck with the Stage IV/16 and no internal pump mods, the EGT's were fine. I had to run a lot of timing to keep the boost around 40 psi.

Don't waste money on an HX-40. The Schwitzer ("B" series - HTB2, Phat Shaft, B-1 Bomber, etc.) based turbos are a lot tougher and have a lot more upgrade potential.

An HX-35 will not be a big enough improvement to to be worth doing.

 

Thanks for the input guys! It's nice to hear from people who really know their stuff.

Wanna- Don't waste my money on the 14WG... just curious as to why you went from a 16 non WG to a 14WG on your truck?

 

To keep boost under control with the water/meth. It was a bad idea, but I didn't know that at the time. I should've spent the money for a bigger turbo.

 

So what you are saying is... H1C with stage IV and 16 cm non WG or just a plain bigger turbo, such as some of the B series?

 

Exactly.

 

If you plan on running injectors plus decent pump mods I'd go to the HTT HTB2 series, II PS series, or a KSB1 or something of the like. I think an HTB2 62/12 would probably spool pretty well and cool over 400hp.

The HX40 compressor side is the same as the HTT Stage IV, but due to the larger turbine wheel and exhaust housing it would cool better. Like others have said, they have been known to break shafts, but it shouldn't be much of a problem under 40psi.

One other comment: According to Paul at HTT, the HX35 Stage III upgrade is the same compressor wheel as the Stage IV for the H1C's.

 

From all the reading/searching I've done here on this great site, I think that the HTBG turbo may fit my needs. The HTT site says that it is good for the 350-425 HP range, and I don't think the PODs have can push enough fuel for more than that. It is also about $450 cheaper than the HTB2. I don't see myself going with EDMs in the future, so I think PODs will be the only injectors my truck will see. Does this sound like a good plan?

 

I'm not too much of an expert but, doesn't the HTBG have a 57 mm inducer. Which really wouldn't do too much controlling EGT's with POD's. If that's the case wouldn't it be more benifical to get a HTT Stage IV rather than a HTBG?

 

That makes for two of us not being experts .

I was only going by what the HTT website said, that the turbo could support 350-425 horse, which would be perfect for me.
