Holset Turbos

[306dsm2.0]

i dont want to be a bother to you guys but have you heard anything on the hy35 housing yet. Im just getting anxious because i got my motor back and im dying to throw this turbo on.

Sorry for the delay guys, but we had to finish the MR2 kit. It will be wrapped up next week and we will be able to finish the HY print. We also had to wait for our next batch of castings which just came in a few days ago from the foundry. Anyone interested please email me directly at [email protected] with your name, address and phone number so we can add you to the list.

I got my H1C today

I noticed it will bolt right on to my tdo6 adapter so Should I try it as it is? Iwould need to get a wastegate though.

I also thought of modifying the housing to block off the second runner of the tubine housing I couls weld a piece into the second part and tapper it up to the inlet to make it like a smaller single runner. What could it hurt to try it. Id rather experiment with it then just tossing it out. I have the facility to do the mods so that isnt an issue.
I know Im likely to get negative feedback just thought Id throw this out there.

Does anybody have any idea if this will work? I really cant see why it wouldnt but feedback would be nice.

Most people that are comtemplating useing a Holset turbo I hope knows that the MAS intake temp sensor is before the IC. So I would assume that by the way Joeracer talks he knows this and it's an aftermarket IAT sensor post IC.

But the profile doesn't state either a MAFT or IAT sensor so it could just be the ECU+ pulling that info. I'm not going to reread this entire thread again but it's not to imparitive as the size of the FMIC is fairly large. The holset turbo's are fairly efficient as far as turbo's go. And anything that is pushing 30+ PSI is going to get fairly warm. I would say above 25+ PSI is where you will see the difference in different FMIC constructions ie... Bar & Plate vs. Tube and Fin for efficency. So lets not get to carried away with IAT's as this thread is for the Holset turbo's and their performance on the 4G63/64.

I am just making sense of his ECU+ data which when running numbers shows some discrepencies. You yourself are not 100% sure which side (pre or post turbo) he was referring to so please do not assume and reply with assumptions. That is why I was asking him. His data shows 71 degrees at 35psi. Pre-turbo I can understand as he may have constructed a cool box around it. Now if this was after the turbo and FMIC as was previously stated (he appears to have edited his post and removed this) this seems to be an extremely low temp for pushing this amount of boost... anyhooo....

I UNDERSTAND this thread is about the Holset Turbo. Do you not realize that you have to consider the supporting mods of the engine? Poor/Superior mods (FMIC, FUEL, INTERNALS) can either make or break this turbo's performance as with any turbo. I am NOT just going to go out and buy this turbo because his ECU+ says the turbo works this well w/o knowing what supporting mods he has (that are relevant). I hope this makes sense to you. If I am running too small of a FMIC or not enough fuel upgrades to manage the volume this particular turbo can produce, then it will run like crap on my setup. In that, it would not be fair to post how :thumbdown this turbo is without providing additional information as to why it may not have performed the way it should have. In Joe's case, knowing and understanding his setup and how it may affect the turbo's awesome performace is key and any "DSM techie" would know this.

Hi, I'm a newbie here....

I've been following this post closely for some time now. I'm really liking the results that this turbo is giving on the smaller displacent engines. I've seen the hx35 run on a 2.3 Ford engine also. I am in the process of making a header for my car and looking for a hx-35.
The difference is, I have a 1987 Mitsu Starion, with a 2.6L in it. My only concern is, that it may be a little laggy. Your 2.0's don't seem to spool them to badly. I do have a little more displacement, but I don't have DOHC or a redline like you guys have. I'm afraid I won't beable to take advantage of a braod boost range. The good old 2.6l likes to choke out at around 5,500 rpms with the bad intake and turbo setup on it from the factory, not to mention a NA cam put in from the factory. I have been upgrading to get away from this, so I can make some power a little higher.

After looking at the compressor map posted here, it looks like this will start spooling nicely around 3,000 for me. That's doible, big time.

Anyways, I had a question for you all? Has anyone ever considered clipping the hx-35 or 40? I honestly don't think it's going to hurt the higher boost at all. I personaly don't plan on running more than 20 psi. And with the large AR wanting to be laggy, I think you'll see some better lowend spoolup and not killer the really high boost. I've read of the Rams running these turbos, pushing 40+ psi all day long.

I am considering this. My tiny 12a only really starts to spool around 2,700 anyways, but peters out in short order. When the car was all stock, around 3,000 or 3,100 I'm thinking is when it started to spool.

I know someone from "starquestclub" said they were running it for some time, but couldn't tell me when it wanted to spool...all I was told was, "it was fast."

Also is anyone running the HY-35? The small non-split tag housing, I'm thinking might spoolup a little faster than the HX. I know it starts to choke out at aroound 29psi from what I've read.

There are some great posts here, thanks for all the info.

^^If you are still using factory TBI, this large of a turbo is not for you. They(bullseye) haven't made the hy housing yet, if you have really been watching this thread.

The car is winterized, waiting on a 60 or 65 mm TB upgrade, at minimum. But probably a MPI setup will be going on it.
They/Bullseye many not have, but Holset has. As in the HY35 (2002 autos and 2004 and newer) the diesel ram trucks are running. I'm not looking for any bolt on kit, I'm making my header so anything is possible.

So Hy, turbo...any input or and input on clipping?

Well these are duh things for most knowlagable people, but maybe it wasn't you and someoene else who jumped on being totally rude. I think the post was deleted. Anyways yes IAT is very good info to have along with your IC dimensions and construction type. I wasn't flamming. It just pisses me off when people get all rude about things before people have a chance to explain. I personally won't have a IAT sensor to show until later this summer. I'll have since moved to the desert and it will really tell the story of IC effeciency and turbo efficency as I'll have two. one post turbo and one post IC just for numbers sake.

Anyways. you can check vehicle profiles and see what someone is running for mods, and hope it's up to date. Info is good to have but he was just posting a ECU+ log to show us what's up. Sorry if I offended you. I'm out.

We are cool bud.

 

[EagleTalonRacer]

so let me get this straight, can we use these turbos on our 4G63T or not?

 

[1029TSG]

Yes, if you buy one of the Bullseye turbine housings.

 

[PSI TSI]

I think an Hy35 will work with the stock Mani if you get an adapter plate made. I know I can bolt my h1c on to my Manifold with My Mitsubishi TDo6 adapter plate. As far as it being to laggy Guys are using them on sohc mustangs and volvos so we should have less lag then them.
Im working on my H1c project I started to modify the 2tang housing into a Single runner since no one has any input to my earlier post. Ill have to just try it. Im going to try to take pics of the whole process so ill post them when I get it done. If it does or doesnt work at least it will be documented here.

 

[defrag010]

PSI TSI, My H1C has the 18 cm housing too, and if yours works out and provides decent spoolup I'm going to have mine done too.
Where did you get your TD06 adapter from?

I made my plate. its a piece of 1/2'" plate with both bolt patterns in it its machined flate on both sides so it can seal. How do you know what size housing you have? Mine is non wastegated so Is it still the same as yours?

I also have a 1/2" Manifold spacer to bing the mani out. Im thinking Im still going to be hitting the water pipe on the turbine side. Im getting a mock up block and head set up so I can check clearnances while on the floor and not in the car. Ill keep you posted on this.

I'm pretty sure mine is the same(no wastegate) will the bullseye housing still work for it? Just want to make sure before I order.

[defrag010]

It is stamped on the turbine housing. There will be a 7 digit serial number, and the size of the turbine housing is stamped below it. Mine is stamped. The H1C's only came with 18 and 21cm non wastegated housings, WH1C (with the w standing for wastegated) had a smaller housing. I don't see why your turbo wouldn't work with the bullseye as long as it's an H1C.

 

[unlikely hero]

Serial number is H 839380 don't know if that helps. This is a brand new turbo but you can tell shes been sitting around for awhile(theres tons of dust on her) what I don't like is theres some shaft play, could this be because theres never been any oil through her? It makes me worried and I just don't want to go through all of this to find its bad. What do you guys think?

[93AWDTalon1]

I'm hitting 21psi at 4700-4800rpms in 3rd on my 60mm hx35/40 hybrid my mods are in my profile. I'm running 7.8:1 cr so mine is a little lagger than most.

 

[maximumbob]

Maybe I missed it, but what are people doing about the funny lip on the compressor housing outlet, with respecxt to the hx 40 and hx35? Just slide the coupler over it or machining it off??

[93AWDTalon1]

I had mine machined off

 

[orangecrush4g63]

put a cupler on it and a t bolt...never came off

Mine has a number like that, and right below the number it's stamped 18. The number below the serial number is the size. I got mine used, and it only has shaft play when I Really push on the shaft. Just sitting there, it doesn't have any play but if I press on it pretty hard I can barely get some play in it. I think it's because of no oil being in there. If I move the turbine wheel I can't get any play at all no matter how hard I push.

 

[MattGVR4]

WH1C's come on up to 95 Dodges, maybe even later models. My 94 has a WH1C. The W just stands for wastegated.

Can anyone confirm that a H1C will bolt up using the HX35 Bullseye housing?

I think most Holset turbos have the size of the exhaust housing stamped in the exhaust housing inlet.

As far as toughness of these turbos go, my Dodge has the original turbocharger. It has 319K miles on it, and I run 40 pounds on it on a daily basis, for extended periods of time, and I "bark" the crap out of it. It has just a tad more shaft play than a new HX40 I have.

The reason you hear of HX40s having shaft failures is because no one runs an HX40 on a stock truck (they are basically all run under high HP conditions), and they have the same shaft with bigger wheels. They are more likely to fail under a "barking" situation than an HX35 or H1C.

 

[unlikely hero]

Well crap I dont' know now, I get about 1mm side play with not any effort at all. I think I'll try to tighten the nut a little and see if that will help any.

[onefastcar]

I have a H1C Holset turbo on my integra, I don't know anything about surge or anything about the turbo is self. I do know that the holset ex flange is a T3. I do know that seems to flow pretty good, but I am only running low boost 4-5lbs. before I was running a .45 a/r turbonetics turbo at the same levels, I really like the holset it makes my car rage after 4K all the way to redline.
