Holset Turbos

[1029TSG]

If so, check to be sure the lever isn't hitting the flange on your o2 housing. If so you can grind it down a bit or bend the lever up just a tad so it will clear, this happens alot on aftermarket and EVO III o2 housings since the flange sticks out past our turbine flange. You can also check and be sure the larger puck isn't hitting the inside of the o2 housing or gasket if you didn't use our outlet gasket.

he has your outlet gasket

i grinded the o2 housing down myself when i had it because it was a shitty fit

and the flapper inside- the wall had to be grinded down for the flapper to clear because it would only open 1/4 inch!

its the bullseye-power holset actuator too.

everything is setup more than fine, but it still doesnt work.

Call us on Monday and we'll go over everything again, i'll put you in touch with one of our techs.

If there's an issue with the wastegate lever on our housing we would be more than happy to adjust it for you. As far as the actuator, you have to purchase our Holset one if you want it to be a "bolt on" affair. Using the stock Holset actuator requires some bracket and rod adjustment to say the least. We dont recommend it but I have a picture of one that a customer of ours was able to modify.

The lever is fine (although the allen head screw comes loose from riding around on the floor of my car, I hope it stays together on the car), it's the placement of the flapper that makes it hang up on the inside of the hole. And yes, it does open far enough to get hung up. Maybe with exhaust pushing against it there won't be a problem, but that is yet to be seen.

I have the stock Holset actuator. In that picture you posted, is the actuator itself shimmed to tilt it in the right direction? It looks like the actuator rod is still coming out of the head at a pretty steep angle.

I just purchased the Hx40/35 hybrid ext wastegate Garrett mani setup.

Present mods on my car are Stck 6 bolt bottom end with 95 pistons,hks 264/272 cams,3 inch exh,660 Denso inj with -8 fuel line,255 walbro fuel pump,AEM EMS standalone,spearco FMIC(2-221) with custom piping.

My question is what is the max boost I can run safely with this thing and do I need bigger injectors than the 660's at some point?Remember I have -8 fuel lines.

I have read all the posts I don't know if I missed it but would the hx-35 be a decent setup for running only 15-20psi until I have all the supporting mods to turn the boost up.

 

[aero_sallee]

What kind of supporting mods do you already have?

>I see what you where talking about with the wastegate flapper being able to stick. But it requires way more movement than any actuator can give to get it high enough for it to stick. So their is no need to worry about it.

>You're right, the actuator travel is not nearly enough to open the wastegate fully.

That's BS. My actuator opens WAY past the point of the flapper sticking.

The housing needs to be rotated (and new tabs welded on for the wastegate actuator) before the turbo will even bolt in my car. The compressor outlet hits the front engine mount, definitely no room for the elbow that needs to be on there. The turbo in this pic still needs to go back over an inch.

The more I do with this turbo, the less bolt on it gets.

It also hits the stock 02 sensor housings.

I have been running hx35 for approx 3 1/2 months.I had issues at first but, I was able to work them out. know dyno runs yet. but did a highway run against an h22 vtech civic w/all bolt ons and a 100 shot. I pulled pretty good. I am AWD. I was runnign 25 psi externaly wasted gated at the time. my mods I have 680 injectors, 255 feul pump, fuel pressure set at 42, gm mass, FMIC, stock tiimng, HKS cams 272's, and dsm chip. Only about 7 counts of knock throught the whole run, on C12. I can 18 psi on 91. With out damn near any knock. Still on stock 6 bolt. pics attached of my setup..... hope it is helpful.

 

[1029TSG]

Please find a way to remove that screen and replace it with a cone filter at least. You'll notice an increase in overall performance and spool up.

 

[bigtim-x]

thanks man yeah I am in the process of doing that just haven't had a chance yet. overal spoil up right know is still pretty damn good. can't realy complain but always looking for better performance. trying to add more pics but having a problem. It says it is upload in process. Not sure what it is doing.

 

[1029TSG]

Good to hear it. Try sizing them down to 600x600 or less.

 

[MattGVR4]

Why do you disregard every comment I make about this thing being lacking in quality? All you can say is something about his air filter? Why pretend like problems don't exist?

 

[1029TSG]

Are you talking to me? What problems? I dont recognize anyone on here buying a complete Holset turbocharger from us, only our turbine housing. If you dont buy the complete unit or actuator from us its strictly a do-it yourself project.

 

[1029TSG]

If anyone has a problem with our turbine housing or wastegate assembly please let us know so we can take care of it.

 

[MattGVR4]

Who else would I be talking to? Why don't you FIX the problem with the housing. If what you are selling doesn't work, something needs to change.

Actually, that is something that shouldn't need to be fixed, it should never have been an issue.

 

[1029TSG]

What exactly is the issue?

 

[MattGVR4]

Like I said 3 or 4 times already, the wastegate HANGS UP ON THE WASTEGATE HOLE. It opens WELL PAST the point of hanging up. That is UNACCEPTABLE.

The HOUSING is advertised as a BOLT ON housing for Holset turbos to a DSM. The only thing that physically bolts up is the turbo itself, nothing else works. The turbo doesn't even fit on the car without modification. The turbo needs to be clocked, and wow, now I can't use factory Holset actuator mounts, new mounts have to be made for the actuator with a TIG welder (Lots of DSM guys have those), the list goes on. The average DSMer would need to take their parts to monster garage to get it to work.

And if I were to spend the money on a complete turbo, it sure as hell wouldn't be one of these turbos that no one besides you can provide dyno information for. May as well call these things MUTTS.

 

[1029TSG]

You can attract more bees with honey (Mutt comment). If the wastegate is sticking and it's not hitting the gasket or 02 housing please send back the housing and we will replace the entire wastegate assembly for you, no charge. If you dont buy the turbo from us there's no chance of it being clocked correctly. If you dont use our actuator then of course you have to modify the stock one. Where does is say that you could buy our housing and a stock Holset turbo from a Dodge Cummins Diesel pickup truck is going to just mount up without any additional modifications or adjustments? How could anyone provide dyno info besides us since we are the only manufacture that produces a housing for the Holset turbo?

I'm not trying to be nice, I'm trying to figure out why nobody put any thought into this piece before they decided to sell it, and make sure people know what they are getting into before they buy it. What exactly can you tell us about the mutts?

I'm not going to have my car down so you can fix something you shouldn't have let go past whatever quality control you have.

Like I said before, I'm not paying that much for a turbo that nobody has any info on but you. Who else could have info? Well I could, if I ever get the damn thing on. Anyone who has one could. Has no one privately bought one of these and dyno'd their car? Plenty of people have dyno info for Greens besides Forced Performance. That's because they WORK, and that makes people a bit more willing to pay the money for them, and then they can take them to the dyno.

What would be the point of buying your HOUSING and then buying a TURBO to go along with it? If the housing doesn't work, DON'T SELL IT. Sell the complete turbos all day long if they work as advertised (again, yet to be seen.)

Let's put this in the proper context:

The quote above COMPLETELY describes WTF D S M O W N E R S H I P WTF .

........cheap, w/stock blocks, expecting quality and results.

(btw, I got my TIG when I got my FMIC )

 

[danamo250]

I have 3 inch turbo back exhaust, k&n filter adpater kit, 2600lb clutch, and thats it. I was running 15psi on the stock turbo until the 7 bolt blew up so all these parts will be on a freshly rebuilt 6 bolt.

I personally love the Bullseye turbine housing. I think you just might have got a bad wastegate. And about the clocking of it you can turn the chra a little to move it some as long as the oil return isn't more than 20* off. Also the Compressor housing can be clocked as well. You just have to remove the locating dowl on the seal plate which is no big deal then you can make it work. The stock actuator will have to be modified which is kind of a mute point since it was designed for the holset turbine housing. Not hard stuff to do. I'm hoping to install mine this weekend if the weather permits. Otherwise it will be installed the weekend after next. I just found out the local dyno is going to have a dyno day in 2-3 weeks. If they let me do a pull with my Xfer case on the ground I'll be able to have a dyno chart for you on my car. My mods are in my sig.

The bolt on turbine housing works as designed. It bolts onto the CHRA without a problem. After that it's up to you to get it to work and fit.

There are more people, even in this thread, that have a "bad wastegate".

I understand how to clock a turbo.

I have tons of wastegate actuators, from stock Mitsubishi to different kinds of Holsets. None come close to working correctly without major modification. With the stock Holset actuator and the housings clocked correctly, the turbo outlet hits the front 1G motor mount long before it's where it needs to be (first pic).

Second pic is that of a modified Holset actuator. Works fine pn the bench, too bad it won't bolt to the car like that.

The oil drain sits right on top of the motor mount, just like a mutt. Weird.

I've already said it bolts to the turbo. That's the least it can do. The wastegate flapper arm could be a bit taller so it clears the O2 sensor housing, but apparently I'm already asking too much out of this thing.

Why don't you post some pics of your setup so we can all see how easy and perfect it works?
