Holy CRAP! That looks monsterous! Any chance you could put something next to it for size reference? How did you come up with the idea to do this? Were you just looking for a bit vgt?

 

Well I was actually curious about using Holset turbos. A guy up here has the fastest 2.0 WRX in colorado with a Holset He351cw. It doesn't have VGT and still spools faster than a 20G. Then I found out about this turbo I thought It was worth a shot. Plus it is unique.
Also Holset is the only diesel VGT turbo that can be used in a Gasoline engine. Because it uses different technology it can handle the higher EGT's.

 

GeneralTJI? His car is SICK. Not to thread jack, but here's a Holset WRX in action!

iv always wanted to do this quick spool like a VF series, then vanes open and pulls like a 35R up top ;D

how are the vanes controlled on that particular one i know it varies year to year some used OIL pressure similar to AVCS or VVT which i think would be near impossible to control but others use a simple 5v stepper motors which would be awesome because in Theory you could control it with a UTEC or even possibly a OS tune

but like you said EWG with a MBC or 3 port for insurance

 

Very nice, read a lot about these turbos over the years, interested to see how it goes.

 

I'm interested in seeing how this turns out as well. I know I will be helping with some of the install and what not. Or I'll just stand there picking my nose wondering WTF Eric is doing. I do hope it works the way he intends, because this would be some bad ass sh*t.

 

I'm glad someone is gonna try it! Can't wait to see what you can do with this thing.

 

Yup GeneralTJI.
He ran an 11 in this vid. For this altitude it is quite incredible. High 12's up here in a vf52 require e85 to reach.

These turbo's have a electronic motor to control the vanes. The plan is to control the vanes with a wastegate actuator.

 

FYI there's a guy on dsmtuners.com who is using a tweaked 14b wastegate to control the vanes along with an EWG for boost control. Apparently with awesome results, I can hunt down the post if your interested.

 

Do want! Seriously i can't wait to see what you make of this. Build journal is a must!

 

Can't wait to see how this turns out. I've never seen/heard of a turbo like that before, pretty cool.

 

They've been putting Holset turbos on Hondas for years now... they aren't very well-known yet, but they are great turbos at an even better price.

 

DSM's too, here's a thread with a bunch of results info as well as links to allot more threads with tons of info.

I can't find the other thread I was looking for however there is a ton of Holset info both in the links in the link above as well as on dsmtuners.com.

 

So i checked ebay, am i looking at the wrong thing or are these really going for $250 + shipping? I don't have the money or the skill to fab the needed parts, was just curious.

yes these are very common on diesel trucks 05+ i believe ??? ram 2500+ with a cummins and they are verry common to come across used because the guys that do alot of towing upgrade them fairly soon

 

I remember you mentioning this idea a while back. Nice to see you got the turbo and are going to be putting it to use VGT!!!

 

Actually there is a shit ton on ebay. The reason why is they clog up and vgt function gets jammed. This was the issue with mine. I had to hit it with a hammer to break it free. Early on, Cummins was having the turbo replaced. So these turbo's started piling up at dealers. Later on they started a process for cleaning the turbo. The literally drilled a hole in the turbo, ran a cleaning solution through the turbo while the truck was running and then tapped and plugged the hole up. So the supply of these turbo's is diminishing slightly. Still ebay auctions are starting at $100 with $50 shipping. I had no other bidders so I got a turbo for $150. Even if this project never makes it's way to completion I will at least be able to rebuild it and make my money out of it anyway. And 150 is not a lot of investment.

I know there are a few diesel guys on here. Anybody know a good way to decoke and clean this turbo? This is my first step in the process. I may have to contact my turbo guy.

 

do you know the mileage on this one and do you know if the ring linkage and vanes are removable

because when i worked at GSD we used to rebuild 6.0L PS turbos and you had 2 options a full rebuild where we would re-balance the compressor and turbine, ultrasonic clean them. everything else would be hot tanked and media blasted. then everything would be re assembled with new bearings and seals so it was like having a new turbo. or we offered mostly for fleets a semi rebuild where alls we would do is remove all the vanes linkage and ring and they would get media blasted and the rest would just get cap plugged and go in the walk away spray tank so it was basically just cleaning turbine housing and the vanes and that was all



but if you only picked it up for $150 then i would just say go for a full rebuild dont cheap out. get the new bearings and seals and start with a freshly balanced rebuilt turbo

 

Well Shit, I was wanting to get an AVO turbo, or atleast a VF52...but damn, this project is making my mouth water lol

I don't know about the rest of you guys, but if there is enough interest I wouldn't mind donating some monies to the final product if need be (even if in the end we find out its not possible).

This seems like a hell of a lot better solution than dropping close to a grand on a decent turbo upgrade lol

 

I would be down for the cause as long as the price is with in my budget ( in the Army, not big balling like most of you ;D)

 

There would be plenty of fabricating to be done (flanges, etc...) but **IF** there were to be enough interest, I can see this being a hot item, just like in the Honda and DSM world.

 

Not if it delivers like a GT35R! a 30R is even about at the limit of the stock internals, all depending on your tune how you drive, or course, but this could be a big power turbo. Think transmission and engine build. Eric mentioned this thing could probably put down 600ft-lbs!

 

ive read alot about these turbos from other forums and i think these might be a little intense for a stock block and diffidently a stock tranny

but i would love to see some vids and dyno of a holset on a 3g, these turbos lag a bit from what i remember but once they hit boost they are a monster

My plan is to just keep boost at a safe level for a stock block. Probably running 20-21 psi straight to redline on e85.

correct me if im wrong but the holset flows way more air(lbs/min) then a stock turbo...from what i remember 10psi on one of these would be like 19-20 on the stock turbo right?so with that said wouldn't 19-20psi to red line be way too extreme for a stock motor and tranny?

 

My plan is to just keep boost at a safe level for a stock block. Probably running 20-21 psi straight to redline on e85. The plan is to get a built block one day and see what this turbo can really do. It may be a bit of a dyno queen until I can also get some PPG's in the tranny. Maybe it will be a killer autocross car. I have been day dreaming about this for a long time so I really can't wait to build it out.

 

I like where this is going!!! Can't wait for more info!!!

 

I talked to my turbo guy and he thinks I should rebuild it. I think at 19 psi I should be at the 450whp mark. Only because of my altitude and real uncorrected whp being closer to 370 can I even think about using this on the stock block. I certainly will be running e85 and would keep 91 octane at about 13psi or so. One day I will explore the full power of this turbo with a built block. Even a sponsor needs sponsors sometimes.
For now I will just work towards this slowly. Rebuild first, get an actuator setup and then have the custom up and down pipes and fmic fabbed up.

 

When is all of this slated to begin?

 

Who the hell knows. Maybe, just maybe it will happen by next spring. Unless I can meet up with my brother long enough to fab me up something. I'll have him bring his welder next time he visits. It will probably get put off longer than your build, LOL.
I will do this one step at a time.

 

Ok, maybe my build will happen sooner than yours. I just wanted to know so I can show up and be in the way and look like I am helping. But I hope it does work out, because it gives hope for others. But on another note, payday is tuesday, and there should be some goodies coming...........hopefully!

I should just go and get a freakin loan to finish this damn thing!

 

i know i'm reviving the dead a bit but eric have you seen this build on nasioc with a juicy holset on an 08 wrx?
