Topic: HX 35 vs. HY 35 (Read 26824 times)

onlyflash944 · « **on:** March 11, 2009, 09:32:12 PM »

Well I thought I'd do a thread to compare and contrast the two turbo chargers that I might use. HX 35 on the left, HY 35 on the right.

Divided T3 for the HX, straight T3 for the HY

Both have an identical 5 bolt pattern for the exhaust outlet, the HX came with a 2.5" v-band, the HY with a cast DP

I do believe this is your standard T3/4, T3, and T4 oil drain flange

Both are internally gated. They are clocked 180 apart

Extra fin for the HX

Close up of the numbers on the HY 35

I know for a fact the HY has a 12mm x 1.50 oil inlet, I have that tap and it fits. I'm freaking looking everywhere for the inlet on the HX and can't find shit. Probably just going to take the whole damn thing to lowes tomorrow and go test fit in the plumbing department.

dont waste your time at lowes they dont have shit in metric

If its an older HX35, you may have trouble finding that specific fitting, i heard of guys having problems with that $:-\$ . Ace hardware has a nice selection of hardware.

onlyflash944 · « **Reply #3 on:** March 11, 2009, 10:27:30 PM »

Yea, lowes is definatley SAE only in the plumbing section. The HX 35 looks like is an inverted flare fitting of some sort, measures about 0.55" ID with my dial caliper. I was going to try a 5/8th inverted flare and see if I get lucky in the morning. Then place an order for a whatever it is to -4 an like the rest of my oil feed shit.

Logan76 · « **Reply #4 on:** March 11, 2009, 10:35:52 PM »

hmm thats a good idea, I would guess its an inverted flare fittings, I dont think its metric, so I would guess that inverted flare would be the next best bet.

good info on the turbos. Thanks

dvst8r · « **Reply #6 on:** March 11, 2009, 11:13:12 PM »

Depending on the HX-35 it is either a 14mm x1.5 or a 12mm x 1.5, but since you have the Hy and I am inferring from what you posted, that it is not the same it is then the 14mm x 1.5.

+1 on Ace hardware, the bigger corporate stores have the absolute baddest ass brass/fitting/connecter collection available outside a dedicated fastener outlet or grainger.

SAE/Metric

yea, but see, I have a metric tap and dye set with a nice little thread pitch measurer, and it didn't seem like the 1.5 fit at all. if anything the 1.75 was closer, but then again i might be stupid or something.

also, its definatley not a 12mm hole. it might be a 14, but i don't have a tap that size nor do i feel like finding a bolt right now to try it. i'm still sticking with 5/8th inverted flare until further notice. I'll also post a picture of the HX 35 inlet, its not just a threaded hole like the HY.

Logan76 · « **Reply #9 on:** March 11, 2009, 11:18:49 PM »

If you have a Fastenal local they stock lots of shit too.

I read that older HX35's had a weird ass inlet like 96 and older ones, but thats just what I read so it may have been useless info.

onlyflash944 · « **Reply #10 on:** March 11, 2009, 11:20:07 PM »

for the record, i have no clue what year either turbo is. I just know that the owners said that they are what they are.

http://mdmetric.com/3550/3501-D.pdf

go to the inverted flare on that web page. in my opnion it looks an aweful lot like whats pictured there.

Well you see I am running one of those turbo's, and have owned at least 5 now, and built several more rides using these turbo's. To the point where I went out and bought a die just for making an oil feed adapter for these turbo's

This weekend when I am out in the garage, working on my truck I will take some better pics of what I did. In short I took some SAE brass one end is 12mmX1.5 in this case, I have also made them to JIC or to just normal 1/8th npt ect... I filed the threads down till this die would start nicely, then ran it over, added some thread sealant good to go, for a year now.

MY HX 35 = 3/8" inverted flare oil feed

onlyflash944 · « **Reply #13 on:** March 12, 2009, 02:59:36 PM »

HY 35 oil feed port, as mentioned above, 12mm x 1.50

HX 35 oil feed port

HX with 3/8" inverted flare steel plug installed. Here is where it gets tricky. This SOB is a 16 threads per inch hole, instead of the WAY more standard 24 tpi. Summit doesn't even carry an adapter for the 16 tpi. So what to do?

Drill the steel plug out

Tap with 1/8" NPT

1/8 NPT is a great choice since they are like 2 bucks to go from male to male, 1/8" NPT to -4 AN on Summit

Test fit

The steel plug I found was at Advanced, and cost 2 bucks. With the 2 dollar NPT to AN fitting I need, I'll have all of 4 dollars in the oil fitting. Enjoy.

You throw a wrench on that and it will turn right out, mine did. I'm betting that's where you'll find the metric thread mentioned above. I tapped a 1/4-20 hole on either side and bolted a flange to it, so I have no clue what thread either are.

onlyflash944 · « **Reply #15 on:** March 12, 2009, 03:42:34 PM »

all ready used a 1/2" ratchet and snugged it up quite well without any teflon. It screwed in 3 tuns with my fingers, another 1.5 or so with the ratchet. I'm happy where it is. As many of these as were made, I'm sure there were different oil inlet configurations

dvst8r · « **Reply #16 on:** March 12, 2009, 06:23:30 PM »

You can unthread that adapter nut on the HX-35, under that is the 14mm x 1.5.

dvst8r · « **Reply #17 on:** March 12, 2009, 06:24:02 PM »

Oh good job, on the rHMT styles adapter though.

tricky tricky

didn't even think of that cause it looked like one piece. anyway, already ordered the 1/8" npt to -4 from Summit.

Depending on the app some don't come with that adapter at all. My last hx35 was off of a brush cutting tank thing, and it didn't have one at all VS the ones that normally come off Dodge trucks that do. From what I have seen there are a few different adapters depending on the application that it was for, but all that I have come across to this point have the 14mm x 1.5 as a base.

thats really good info.

for the record, and the cheap

like me, a 14mm x 1.50 to -4 AN was $12.39, and the 3/8" inverted flare plug plus the 1/8" NPT to -4 AN was $3.24 (1.99 + 1.25)

Nice.

This weekend I will show you what I do. It consists of $.50c of brass, a file, and that Die.

that's what I meant say, not that onlyflash's adapter was going to fall out. I suck at getting my point across.

Pretty sure I know what dvst8r means for re threading an adaptor for it.

I think both of your ideas are less time consuming then the flange deal that I made, but I used what I had at my disposal.

LOL, look at the black whornet thread, we made an adapter like that, but way more ghetto.

onlyflash944 · « **Reply #26 on:** March 14, 2009, 04:54:47 PM »

i have the shittiest set of internal snap ring pliers in the worlds. allready tried and they don't even reach hole to hole on the compressor housing rings. The HX 35 bolts the turbine housing together, the HY 35 uses a v-band. Just gonna have to fight the rust.

i broke another 1/2" ratchet getting an axle nut off the other day, and an adaptor for the 1/4" drive so i'll be making a trip to sears soon. they have a good set of inernal snap ring pliers, i'll get them and definatley do it. I'll have them apart before I use either one, I just don't know when

Drill the steel plug out

Hex plugs make the BEST custom adapters! The ones I make the most are 1/4" NPT to 1/8" BSPT for the stock oil sender.

The only issue with that custom plate is the mating surfaces. You're pumping pressure through that part, and if they aren't flat and cleaned to death before sealant, they'll usually leak (but not always). Looks like yours has enough silicone to stick a horse to the ceiling.

Back to the turbos, the actual compressor wheels used in those turbos is hard to tell w/o looking at them. There are 6, 7, and 8-fin wheels - 8-fin wheels are a bit more efficient, but 6-fin wheels flow a bit more.
