I have been trying to replace my Turbonetics T04B 60-1 .96A/R .70 trim 4"inlet p-trim big shaft 360° bearing CHRA through MJturboshop.com.

MJ turbo shop says they are having difficulty sending me a replacement CHRA since they are not sure of the size etc. I called turbonetics to get some info but they told me I told MJ turbo shop everything they should know to replace this.

(told turbonetics this is the second turbo so I will not be dealing with them anymore)

For some reason the price has gone up to. On the phone they said its not a problem to send me the part but now that they have the money its difficult to get the correct part and it might cost me more. They are requesting me to send the turbo or the turbine housing to them so they can match it. For me that is not ideal since paying for the shipping is useless etc.


Any info. What can I do to get the proper CHRA???

This is going on 3-4 weeks. I want to settle this.

 

SIMPLE. Tell them its a T4 CHRA with a big shaft (if infact you are running a big shaft) and 360* thrust. Thats all the freakn info they need. If your turbine shaft is toast, then tell them big shaft (if infact thats what your running) P-Trim turbine. Its really that simple, if these guys don't know what your asking for then steer clear, this is simple and common turbo terminology. FWIW have you tried CHEAPTURBOS.COM yet? Also, you understand that CHRA is the entire center section right? I mean if your bearings are blown, just buy a rebuild kit, its mucho cheaper then an entire center section.

Were would I get a rebuild kit? Also how would I get it balanced?

Thanks for your help

 

Any turbo dealer should carry a re-build kit. As far as balancing... its not necessary unless you have blade damage. Just make sure its cleaned VERY well and pay attention to how the turbine is "clocked" in relation to the compressor wheel. in other words, make a mark / line so that the compressor wheel bolts back on in the same position on the shaft as when you took it off. Besides, if you were planning on buying a CHRA, you would of had to go through all this anyways because you would of had to dissasemble the entire turbo to swap over the turbine, backplate, compressor and misc parts...........

Balancing on t3 and t4 and bigger turbos isn't done to ubber tight tolerances people here seem to think. Mainly only full ball bearing turbos and turbos smaller then a T3 (ex: T25) get full VSR (dynamic and static balancing) balancing from Garrett and most Garrett suppliers. The turbines and the compressors (T3/T4 and larger standard bearing)come from the factory balanced seperately and are assembled and thats it. No dynamic balancing at all. There are very very few turbo companies that do a full VSR balance on standard bearing turbos new or rebuilt unless you request and pay extra for it. there are some exceptions though... like Innovative Turbo VSR balances ALL of there turbos. VSR balancing is a computer controlled and calibrated device. Once the turbo is built and assembled completely with the exception of the comp and turbine housings, its mounted on a VSR machine, this machine supplies oil to the turbo and spins the turbo up and takes note were material needs to be machined off then does it (older models you have to machine it off manually) to balance the entire rotating assembly.

get a rebuild kit and do it your self for under $100, slap it on and go boost. Like I said, any Garrret parts dealer/ turbo retailer will carry re-build kits, ask around for the best price. Make sure that you infact have a big shaft and not a standard shaft by measuring the shaft diameter with a set of mic's or calipers and tell whom ever your purchasing the kit fromthe diameter sothey can determine if its standard or "big" shaft.

As I've stated, all ball bearing turbos are VSR balanced, if not they would self distruct rather quickly

BTW, I've always notice you always describe your turbo incorrectly.

"I have been trying to replace my Turbonetics T04B 60-1 .96A/R .70 trim 4"inlet p-trim big shaft 360° bearing"

Correctly listed:

T04B 60-1 compressor wheel. (60 trim)
T04S compressor housing, .7 A/R (not trim) 4" inlet 2.5" disscharge
360* thrust bearing
T4 P-Trim turbine
Big Shaft (I dunno if you have this option or not)
T4 undivided (open valute) tangical turbine houisng .96 A/R

Its a pet pev..... sorry

~Mike...................

 

I see. I think it may be that the shaft may be bent. When you push on the turbine wheel it binds and is hard to rotate.

Turbonetics can be replaced with garret rebuilds?

My bill stated

When I sent it back
Part # 20371 Bearing housing Big Shaft Rev B. Wet and Dry.

Original Turbo purchase
Part # HF11123J093 60-1 P.96 Full size turbo
B.S. 1/8" oil inlet/dry 4" polished comp inlet.

That is it.

Thanks for your help.

I guess I've always had the trim size wrong.

 

Ok, sounds as though you have a big shaft, and you also have a "wet" CHRA, meaning you have water cooling along with oil lubrication. Its not too common to bend a shaft. Infact is very rare unless there has been debri that struct either the turbine wheel or comp wheel HARD or you had very severe surge. FWIW if bearings go extremely bad you can hear comp/turbine wheels hit there housings. If your hearing this something is really wrong and you should have the turbo looked at by a good shop.

"I guess I've always had the trim size wrong."

No, you confused the compresor covers .7 A/R value with trim.

"Turbonetics can be replaced with garret rebuilds?"

The vast majority of turbo suppliers and retailers (Turbonetics, Innovative Turbo Systems, XS Engineering, Turbo XS, Performance Turbochargers {PT}, ATP turbo, AiResearch, Majestic, CHEAPTURBO.COM etc etc etc... even these pieces or JUNK ebay turbo suppliers XS POWER, Stone Racing, MASTER Power etc) ,use Garrett parts or garret clones. Nearly ALL Turbonetics parts are Garrett or Garrett based parts. So actually it should be asked "would these Turbonetics parts fit my Garrett turbo?"

Good luck, it sounds like its toast it really should be looked at by someone turbo knowledgable.

First off, get your turbo back immediately. Those guys obviously have no clue whatsoever.

I can *highly* recommend Forced Performance in TX for any of your turbo charging needs.
