Modding the center housing
 

Will ceramic bearings be evern better?

Re: Modding the center housing
 

I drilled mine out and used two rc car ball bearings. The hobby shop had a set that was a perfect fit on my shaft. Spools about 450 rpm sooner then before :y

Re: Modding the center housing
 

make sure they're teflon sealed. 5x11 bearings fit, but you can use 6x11

Re: Modding the center housing
 

thats sick. practically free upgrade

Re: Modding the center housing
 

I wont have any lag as it is with a dsm t25. I may give this a try before i'm ready to send the turbo off to be refitted for a t28 chra.......

Sleeper status.

Hi, you think ceramics would make a difference? Spooling from 2500 to 2000, man that seem like something to aim for ;D

Ok, I don't want to show my age, but what's a TARDS?

Re: Modding the center housing

:l

That looks like a ------- skateboard bearing. Are all the cages for BB Turbos that low of bearing count?
I mean less BB = less force distribution

I mean it's not like it's a lot of force on it, but the rotation. IDK seems sketch.

Re: Modding the center housing
 

if they are teflon sealed, that wouldnt allow oil to the bearing though?

Re: Modding the center housing
 

the seal is only on one side of the bearing. teflon side out.

Re: Modding the center housing
 

oooooh, ok.

Re: Modding the center housing
 

thats a great idea... :)

any part numbers for the bearings?

Re: Modding the center housing
 

www.towerhobbies.com search for 6x11 as a search term, all one word. look for teflon or full sheilded

Re: Modding the center housing
 

Do you use these for the turbine and compressor side? If this really works it really changes the game when it comes to ball bearing turbos, you can get a cheap 500 dollar turbo and make it a 1000 dollar turbo with 50 dollars in parts.

Re: Modding the center housing
 

it goes in the center section (chra)....aka title of the thread

Re: Modding the center housing
 

it's more like $6 in parts.

Re: Modding the center housing
 

would bearings like this work as replacments for journal bearings in a MHI turbo? The bearings in a MHI have holes in them to allow the lubirication to come through... how would you mount a bearing in a turbo with that style oiling?

I did a search and went back to 05 but couldnt find any more info on doin this mod... i love free/cheap DIY performance so any more info would be killer

Re: Modding the center housing
 

finding the bearings is the biggest bitch, that's the reason you really don't find anything on this mod. it's like finding a flathead longblock NOS in crate, in the back of your choice of still in business ford dealership

Re: Modding the center housing
 

There's no seal on either side and yes, it's similarly sized as a Abec7 inline skate bearing but guess what: it's not.
and it's unfortunately not as simple as throwing-in a hobby shop bearing. Otherwise, everybody would do it. :1
The shaft has to be machined down and the thrust system is different than the standard one. However, it uses a standard dynamic seal backplate.

Re: Modding the center housing
 

you take all the fun out of life, blaast. also, on a td04l stock wrx turbo, what compressor upgrades can i do?

Re: Modding the center housing
 

Well that bearing does not look so special at all. I also don't believe they made bearings just for the turbo. I believe someone came up with the ideal of trying it.

Blaast just what type of thrust bearing are you meaning?

Re: Modding the center housing
 

Hi, how did you get around the issues of the thrust as Blaast mentioned?I'd really like to mod my twin T-25s before I upgrade for the T-28 compressors, so if you have done this process please share?

Re: Modding the center housing
 

yeah i might try this on my ihi turbo, but would need more info on what you did.

Re: Modding the center housing
 

Re: Modding the center housing
 

I think the bearings won't be hard to find. Presently I'm looking for the ceramics. However Blaast shared some info about other pitfalls. Just hoping to hear more on the pitfalls :-\

Re: Modding the center housing
 

Hell my Mitsu 15G in my 850R is on it's last leg so I'm gonna give it a shot.

Re: Modding the center housing
 

Hi, do you intend to just install the bearings only? Blaast point should be taken into consideration also. My T-25 nut is so tight it won't budge. I need to see just how the oil flows to each side of the turbo shaft.

Re: Modding the center housing
 

why did you edit your post?

dont be scared of the sponsors... this site was build on thinking out of the box ;)

Re: Modding the center housing
 

Hi, I edited my original post was due to having a few member respond as children. I really would like to get something out of this. I believe the turbo world did not make a new center section for the ball bearing. However I don't know this to be true. I'd like to know of the many difference or if there are that many differences in moding the center section. The number two post I've even e-mailed him attempting to fine out just what does it take to do the mods. Still no response, next Blaast shows the bearings but next stated the pitfalls. I even tried to disassemble a T-25 in order to see the oil passage. Some turbos have a parallel oil supply to the bearings (this the drilled holes on the outer bearing surfaces. If the oil supply is parallel, and does supply oil to the outer bearing (OD) surface; installing the type of bearing that will seal up the oil supply will cause a turbo failure.

Re: Modding the center housing
 

You gotta remember this is HMT so take everything with a grain of salt. I was just gonna give a whirl as I'm buying another 15G and can experiment on the old 15G. Now if this is like some aftermarket snail then I don't know if I'd try it and really toast it. Any old stock oem snail I'd give it a whirl on. I wouldn't mind picking up a thunderchicken 63/60 and trying it out. Being when I do upgrade beyond my little 15G I'm gonna rock that 63/60 pump. O0

Re: Modding the center housing
 

Are you ever going to answer what it takes to mod the center section?

Re: Modding the center housing
 

A baby, a dildo, and patience.

Re: Modding the center housing
 

:l

Might want a doctor to check that out.

Re: Modding the center housing
 

what do you want to know?

Re: Modding the center housing
 

Thanks for replying.
1. did it take maching the center section?
2. what type of thrust bearing?
3. so far, how's it holding up?
4. do you have any pictures of you turbo while in pieces
5. was is a DSM T-25
6. if it was a DSM T-25, I have a DSM T-25, and I have taken it apart. I have noted it has a bushing type bearing (as should be), but what I noted was the oil supply to the bushing/bearing had slots in them for oil supply. How did you address the oil supply to the bearings?
And again, thanks for your reply.

Re: Modding the center housing
 

bumping up and old thread to see if anybody has more information on this since it was kinda just left unanswered.
i just picked up a 60/63 and wouldnt mind trying this.
any more info?
