I'll let you look at mine when you come over tomorrow. It's an HY35 and was used on a 2.4 motor.

RUN IT.


I've been looking into these for a while, and here's basically what I've come up with from research.....

The HX35W comes on the manual trucks, the HY35W comes on the automatics.

Compressor sides are the same on both turbos, but the HX35W has a bigger exhaust side. The exhaust housing has a split inlet on the HX though, and with a pulse manifold with the right pairing (1&4, 2&3) the HX should spool up as fast as an HY, maybe even a little faster. One thread said the pulse manifold will reduce your spool time by 1000rpm.

The general consensus from what I've gathered is it's probably too much turbo for an 8v unless you're HEAVILY ported, but it should do well on the 16v. It's really coming into its own at 30psi, and you can probably run 40 if you like.

The downside is it's not water cooled. If you give it proper cooldown time you'll be fine. Cummins recommends 5 minutes at idle after heavy towing.

Lots of turbo ford guys have run the HY/HX35W on their 2.3s, and I think a couple have even moved up to an HX40.

Since you're going TIII, I bet you'll love it. I've already got 2 HY's to rebuild in the garage right now for when I go 2.4.

thanks for the info about the HX versus the HY, I was always wondering that myself. I've also heard that people running 16v have had great results with the hy35's, but I too think it'd be way too much for a stock or barely ported 8v head to spool decently.

Simon - how cheap? I picked up one of my HY35Ws for $51 shipped, needs a rebuild and an exhaust impeller though... Hoping to take the one off the other one I bought with a jacked up compressor side.

Watch them for a couple of weeks, you'll see one or two go DIRT cheap.

Simon just left a little while ago from my house. I showed him my HC-1 (for some reason I thought I had an HY) Holset which has a split inlet as well and a huge exhaust side. It was run on a 2.4 16V motor as I also have the manifold and external wastegate for it. I put it next to my T3/T4 .48 stage II turbo and it made it look tiny! lol

Its up to $39 and its not broken, it also comes with a DP. If I really wanted, I could bolt it up and go, :thumb:

I am using an early (98?) hy35 on my 2.5 16v,and I find it to be great.I only run up to stock smec boost cut-out,and find that it is hardly any less responsive than the ford .60/dodge .48 combination I was previously using.Once it begins building boost,it builds and pulls very hard,excellent for the money these things now cost.:thumb:

If you can get your hands on a Natural Gas Cummins truck engine's turbo it will have a water and oil provisions on it's Hx35. I have one on my neon but, I do not use the water cooling ports.

I posted on TD about using a Holset HX35 on an 8 valve 2.5. I never ended up trying it because I needed the car for a driver and it was basically uncharted territory at that time. Still, the thread ended up with a good bit of useful information if you're interested.

That's a good idea. I'd still like to hear results from anybody that's fooled around with one on an 8 valve engine. The HX35 I bought is still around and if John doesn't end up using it on his 16v project, I may end up trying it eventually for curiosity's sake if nothing else.

How are you going to mount the wastegate actuator?
I made a simple clamp for the compressor intake filter that has a mount piggybacked for the actuator.I used a large can from an old turbo,and modified it's rod to be adjustable.
I could take some pics if you guy's are interested,it's easy to get at.

Millerman340
01-03-2007, 09:39 PM
Now to make it work, Unless you buy a complete setup the housing does not come cut to use the v band flange. So you have to remove the divider. Also the 38mm puck hits the v band to soon for my liking . I'm going to mill a slot or dish in the cover to make more room.

Well I went low tech to cut it out. Used a hand grinder to show that it can be done without using a drill / mill press. If u do this watch where the flange thins out. I made it wide & cut through at the corner, Welded it up from the inside & reground it again.

I would like to know more on an 8 valve setup. I found one super cheap.

I have read all the other posts and threads but still have more questions. How will it work with a 5 speed? Everyone running one seems to be leaning to an auto. Also, how about making a header to place it over the top of the tranny/ would that make it spool a lot slower (higher R's needed?) Would one run better on an early head or a later head? I havw both in the shop so I could go either way. Obviously 3 inch exauhst. lol This would be a DD ,but wouldn't be getting opened up all the way everyday. Any more light on the subject would help a lot.

Some jy finds for the swap, These came off a power stroke ford van. the 3" v band 90 will work for me & only cost me $5 . The 4" to 3" elbow was $10 & the v band clamps were free! There is 4 more of these Vans sitting there.

It's alright, we didn't really want to wait for the pics either:thumb:

I am assuming one bung on the DP is for the O2 sensor and the other is for wide band? The Innovate system says not to expose the sensor to higher than 900' f Are other wideband sensors more heat tollerant that their 'Cadillac' sensor?

When's the maiden voyage???:thumb:

Millerman340
01-16-2007, 10:27 PM
well I guess I should have checked that out before I put two that close! I've already had it out. It spools like the stock turbo to me but just does not hit as hard at low boost. I had by brother with me & he said it feels the same as the last time I took him for a blast. So until the trim cal goes in at least the head gasket will stay happy:eyebrows:

But on topic :) that setup looks great :thumb:

Millerman340
01-17-2007, 07:30 PM
Yea it's neat but I'm not sure that it's that cost effective vs a hybrid turbo. I have over $700 in this project already. I had to cut the ear off the tranny, cut the stud off the bobble strut & the compressor housing is hitting the shifter cable housing making the shifter cable bind a little I'll fix that when I replace the trans. Now I just turned the head gasket into a toro sprinkler (just a small spray right now) even at the same boost level that the stock snail was running. At least the exaust pipe has v bands on both ends to put another bung downstream for a wide band sensor. But on a positive note I can't really tell much difference driving the car.

Millerman340
01-19-2007, 10:34 PM
I took the r/t to work today ,Well since I'm needing a head gasket anyways I closed the g valve to see where I hit boost cut. Keep in mind that everything is still stock.(Let me tell you that this thing will be a rocket when I get a trim cal & put all the necessary parts on to support the holset). Now back to my story, 1st & 2nd are pretty much rendered useless except for the squalling . You can hear & feel it spool about 2500 or about the same place as the stock Garrett and unless someone told me that there was a hx35 on there I would not know. I guess with 1st there is not enough load to spool past the cut spinning, It hits the boost cut about 4 grand or so in 2nd spinning , 3rd hits the cut about 3500 or so rolling in from about 2000 .It's about the same for fourth. I'm assuming that with the waste gate having to open way before the turbo hits 14 lbs to keep it of the cut that was why it felt soft when I first drove it. The feeling that my assometer was sending to my brain made a big grin come on my face that's still there typing this:wow1: :wow1: I was almost home I got on it one more time & blew the hose off the turbo outlet. I can see why people like the hybrid if they run like this but I've never driven one so I have nothing to compare to as far as spool. I'm trying to give the most unfiltered thoughts about the holset that I can.
I just hope that the Bullseye housing does not choke the turbo off a higher rpm under high boost.

Well hello everyone.

I am from Bullseye Power and was googling our name and came up with this thread. I am glad to see that people are using our Holset turbine housings. We have sold tons (literally) of these turbine housings and always seem to get great response from any one that has used them.

We have had one customer that made 560whp on a 2.0L EVO around 30psi so that goes to show that our turbine housing can flow enough to make great power.

Anyways I just thought I would drop in and let you know if you have any more questions I would be happy to answer them.

We can do the machining on the divider and the V-band adaptor. We have had to do that on some other applications. We have that figured out. :thumb:

If you want to let us have your DP for awhile I might be able to get a production run made for anyone else that would like to use our housings.

We can do other turbos besides the the holset. We can do it for the Mitsu TD05H turbine wheel. What I would like to see if the New Borg Warner "S" lineup on some of these cars. It is really hard to beat the bang for the buck of the holsets.

Send me the B/W & a housing and I'll let you know!. When you try to bolt up the v band cover the bolts hit the housing. I'll add a link for you to see.[ there is 3 problems there can't get the bolt in without cutting the flange ,no clearance for the head & the mounting surface is not flat so you have to grind it flat for the bolt or nut. Dave.

BEP Nick
01-30-2007, 05:55 PM
OK. I see what you are talking about now. Only have that problem on the 3" v-bands. There is enough clearance on the 2.5" ones. We have done two things to get around that:
1st- use studs instead of bolts there. It makes it a tiny bit easier.
2nd- We have welded the v-band flange onto the turbine housing. Makes it REALLY hard to change the wastegate if you ever needed to, but most people never will have to touch that.

...You can hear & feel it spool about 2500 or about the same place as the stock Garrett and unless someone told me that there was a hx35 on there I would not know.

So, just out of curiosity, how would you guess it would spool on an 8v 2.5?
If you're saying it spools about like the stock Garrett on a 16v, and we know people have used the stock 16v turbos on 8v cars, maybe the Holset wouldn't be too bad on an 8v...
I'm pretty curious about this and was planning to put an HX35 on my old Daytona but scrapped the idea because it hadn't been done before and I needed the car to drive. That Holset and a redrilled exhaust manifold are still around and the Sundance needs rid of the little mitsu.:)

I'm gonna have to read back through this thread to get caught up, so forgive me if I'm asking something that you already covered. What's the difference between the bullseye housing and the stocker? When I was considering doing this initially, I was planning on cutting the divider in the stock housing back a little and knife-edging it.
John and I actually had it mocked up on an engine stand at one point and it looked like it was going to fit. I seem to recall that clearence between the compressor housing and the bottom of the intake looked a little tight, but probably nothing that couldn't be cured with some grinding. We were fooling with this in an open carport in the winter last time which is a big part of the reason it didn't go to far. Now that I've got a heated garage to work in, I may just give it another shot.
Only problem is I gave John a bunch of my spare parts when I moved including the Holset and spare engine blocks. I need to see if he minds if I reposess the Holset and borrow a block so I can get it on a stand and work out the details like compressor housing orientation, downpipe and wastegate. I'd like to get all that taken care of before I pull the head on the Sundance so the swap doesn't take forever.:thumb:

Millerman340

Tony Hanna
03-23-2007, 03:17 PM
Well, I finally got around to mocking up the Holset/redrilled stock manifold to see if the compressor housing would clear the bottom of the intake. It does with about 1/2" to spare.:D The only issue I can see is limited space for the wastegate actuater rod, but a couple bends in the right places should clear that up.:)

The HY35 is a better choice for 8V turbo dodges. It has a slightly smaller compressor wheel than an HX35 (but not much, and certainly much larger than even a 50 trim T04E) but the turbine is much much better suited for our cars. An HY35 is probably good for 400+ WHP, HX35 should definitely only be used in over 400 WHP applications and definitely drag only cars.

Maybe...
But the divided tang turbine housing on the HX35 offers a bit of an advantage. I don't think I have the room to make a proper header to take advantage of the divided tang housing without some serious fabrication and firewall clearancing, so I'm planning to eventually build something like this to go between the stock manifold and turbo.
http://www.speedshopthagard.com/pics/projects/280Z_Turbo/spoolyjobby1.jpg
I'm gonna use an old wastegate can as an actuater for the valve instead of the cable rig in the picture. In theory it'll block one side of the housing effectively halving the a/r. The increased velocity should spool the turbo pretty quickly. Once it's building enough boost to overcome the spring in the actuater, the valve will open the other side of the housing for full flow. A G-valve type mbc inline with the actuater would add even more control.:thumb: I just need to figure out what to build the thing out of. I think the one in the picture is hastelloy. I'll probably end up going with mild steel for the plate and inconel for the valve and pivot. I should be able to fish something out of a scrap pile on a job that will serve the purpose.:)

Millerman340,
If you're still following this thread, what did you do for an oil feed line? I'm thinking about just using stainless braided from a local speedshop, but the inlet on the Holset is an oddball size (12 mm I think). I need to find something to go from that to whatever size AN fitting is on the line I get.
Speaking of which, the fitting on the distribution block is AN isn't it? I wonder what size it is?
Thanks,

An HX35? Pretty much yes unless you are making ATLEAST 400 WHP. Like T3RSE said the for 8V guys are making 500 HP on the HY, if you are capable of making that power with the smaller HY why sacrifice the spool-up of the larger HX?

Another little update on my project. I got a block and engine stand for mockup. The compressor outlet is going to be a nightmare. There's about 2" between the outlet and the back of the head. I think I can make it work though. My plan is to buy a 2.25" short radius 90* cast aluminum elbow, cut the compressor outlet back enough to make room for the elbow to fit, then weld the elbow to the outlet.
Any thoughts?
Thanks,

I know what you're talking about. I'm seriously short on funds myself. It's bad enough that I need to check my bank balance before I spend the $28 for the aluminum elbow that I need for the compressor outlet. :o Luckily I got the turbo a couple years ago when I was working. It's just been sitting around waiting for a home since then. Most of the other stuff I either already have laying around, or know someone that does. If it wasn't for myself and most of my friends being packrats, this project would be dead in the water.:)

Hey guys, I just picked one of these Holset turbos out of the T R A S H here at work. Yes, I said trash, it got sent to scrap metal, and well me being such a car guy, couldnt let it goto waste. It has N O shaft play and the wheels spin free with no grinding or anything, the blades show NO wear at all.
Problem is, which model is it? I looked at the ID tag and it did not say HX or HY anywhere on it. It has the split exhaust housing, and the 2-step 'bulls eye' intake, the center section has a V-Clamp and 4 bolts on the compressor, and 2 C-brackets and 4 bolts holding the exhaust. It also does not have a bolt-on down pipe, it is V-Clamp style, meaning I would have to run an external wastegate. I looked at some of the turbos pictured here and it does not have that bracket looking thing near the outlet for the compressor.
Can anyone clue me in as to which model i have? I will look at it again when I get home and post up the item number if that helps.

Can you get a pic? Right now it kinda sounds like a H1C (early version on the HX35) and they are non-wastegated with uge turbine housings. You can find a 12cm wastegated housing from and HX35 for pretty cheap and it's a bolt on.

Well, I should have some before too long. I got called out on a job working 7 12's so free time is almost nothing. I've got the compressor housing and elbow ready to weld together, just need to run it up to John since I'm not set up to weld aluminum. After that, all that's left is to fab some kind of exhaust outlet, and mount the wastegate can. It should be ready to go on then.:)

Care to post up some details like engine mods (port work, etc), anything done with the cal to improve spoolup, ignition timing, and when it spools? Also, is that the divided tang 12cm^2 turbine housing? How does the wastgate act? I've heard they'll boost creep badly unless the wastegate opening is enlarged...
Sorry for all the questions, but I'm getting pretty close to having mine ready to go on, and I'd like to make sure I've covered all the bases.:)
Thanks,
Tony

Thanks man! The RPM at onset of boost, full boost, and max boost psi would be really handy too whenever you test it out.:)
