Couple Q's about the HTT

[FMOS]

It took me awhile, but I'm slowly getting it together haha.

I pretty much gave up saturday night when the stock oiling location didn't work right off the bat. I'll get it together though. Worst part is just trying to plan for all these little issues ahead of time so that when I'm actually near the truck I can get some work done rather than run around gathering BS little parts

the plug down by the oil filter is a 19mm. if you are looking at the block from the driver side front tire... the plug is located just above the oil filter bracket assembly. remove it from the block and install the -6 fitting that should have come in your kit. the instructions state that "you must remove the metal ring that is surrounding the rubber o-ring on the fitting prior to threading it in. be sure not to overtighten so much that the rubber o-ring becomes distorted."

also... if you are still stuck you can find pretty good instructions from the bd website which also has some pics that may help out the reading impaired

.....Pictures..... the universal language!!!...

 

[NWTDIESEL]

Yes the BD website has good instructions. I can send you a pic of where the oil supply fittings go. Do you need it?

The oil line from down by the filter makes sense. The fittings will work down there anyways. Still not sure about that 90° elbow on the oil inlet of the turbo... I thought that it screwed right into the center piece of the turbo. I actually first thought that there should be some sort of mating flange piece that bolts down there with two bolts because it is a machined surface obviously for a gasket. But then I noticed that the threaded hole was tapered pipe thread...

Anyways, thank you all for the support. I'm actually back at work for two weeks long ways away from the truck but I think my bro is working on it a bit and I relayed the info to him. I think it will all come together now.

Only thing he noticed when I talked to him just a few minutes ago is that the turbo doesn't seem like it sits flat down on the the three bolted mounting faces... is it required to use a spacer or can it bolt in the factory position with no spacer?

As for the size and stainless... I roughly measured the compressor at 2.6x... does that make sense? I didn't have a metric rule near me when I did it haha.

And... I requested the stainless housing, and thought I paid for it. but as I originally asked, what kind of stainless is used to create the turbine housing? Because on the turbo I received, the compressor housing is aluminum, and the turbine housing is steel. Now it appears to be carbon steel, and it is magnetic, but they might have used a ferretic stainless like a 400 series to make the housing so I dunno. Thats why I asked because 400 stainless is still magnetic. It would have slightly better high temp properties, but not like 300 or another high nickel/chrome would have.

It is a 400 series SS. It will rust a little.

The word I got from HTT was that it was some kind of special "boballoy" stainless.

I figured since I have a background in metallurgy and work with a lot of different materials on a daily basis that I would have heard of it, but I never have. Eeven an extensive search brought up zero results.

So yea, my diagnosis is that it is a ferritic stainless, maybe not 400 series, I think there are a few others.

Don't be fooled by HTT:cool2:

 

[FMOS]

Yea, well you know, I was going to call filthy BS on him when he was telling me this...

But whatever. If I was really that curious I would break out my "in-situ metallography" skills and figure it out.

Turbo is on and works fairly well, I'm happy.

 

[WolfLMM]

It's a good turbo, I liked it on my LLY.

 

[SIKDMAX]

bump for me to find earlier.

Did anyone need to run a spacer between th e T3 and turbo? The turbo housing is hitting the end of my pedestal studs before it seals

i have ran mine both ways , i would run a 1" spacer it looks better being out of the valley and is a touch easier to work on , to run with out a spacer you need shorter studs .

 

[SIKDMAX]

LOL Dammit I really freaking hate "KITS" that arent even close to what we need.

So if I spacer I need to make a longer oil drain spacer too, and that would be lame.

GRR.

Anyone know what size that stud is so I could get a shorter one for that corner? Wonder if I could just cut it?

the kit should contain everthing needed for install ? I got my spacer& studs from MPI and Nathan said it came with the HTT kits , mine started life as a BD and it did not come with a spacer but still needed a spacer for the oil drain tube .

 

[WolfLMM]

Take a hack saw and cut the offenders. Then file the bur off them.

If I remember it is the rear passenger stud that is the worst.

I just put my first htt kit on, i am way way impressed over the other kits ive put on, there were two sets of studs in my kit, the long ones hit the turbo, the short ones were fine, if i put another one on ill put a spacer it it just to make more room around things but it didnt need to have one IMO!

 

[SIKDMAX]

Hmm, only 1 set in my bag for sure!

 

[05_LLY]

Maybe they relized the trouble and fixed it, i just put this kit on saturday!!There was a bag with two bolts and two short studs in the box with the turbo, and then there was a bag with 4 long studs in the bd install kit, i used two long studs from the bd kit and the two short ones that came in the turbo box and it worked great, a way more complete kit then my gt40 was, it came with 4 bolts that werent even long enough to get the nut started on!

you go with the 66mm or the 71mm?
