- You never know what's actually inside unless you take it apart! Today we are giving you a front row seat to see what's inside of this turbo. Bearing, VNT vanes and more - ohh my!
Need a turbo for your Cummins ISX or X15? We've got em!

I use slick50 for re assembly it’s better then oil as it has linkade in it which coats parts and makes them slippery
Would be better without the music, good video though
Or at least the music volume much lower than their talking.
does it have a reassembly video for this specific turbo
How do you get that plate out after taking the bolts out?
gracias
What IF🤔.....someone(Borg Warner) invented a performance version of the Cummins/Holset VGT that functions normally & accepts the Holset actuator? Imagine getting a 78/1.32 VGT that can function as a 1.25 or 1.20a/r under acceleration & when the jakes are activated. Plus, using the standard bolt flange & T6 flange would give a variety of options, too.
Turn the music up I could almost hear it!
I have a turbo with the cold side impeller dented from debris, would it be okay to just replace the impeller without getting it balanced after?
I would recommend having it balanced.
When you say that these nozzle rings are infamous because they get stuck, can you please explain in greater detail?
In my experience, the nozzle rings have great movement as they slide in the shroud plate. The riveted actuator rods always seem to have just the right amount of play. And the foils/vanes hardly seem to have too much FOD damage or abrasive wear.
It would be great to know where these NRs get stuck in your experience. I appreciate the video, excellent work. Love seeing these VGTs compared with turbos that have all those articulated vanes.
The vanes can be distorted from excessive exhaust gas temperature, or any foreign impact. Either of these events will cause the vanes to become lodged in the unison ring. On rare occasions, excessive soot build up can cause the vanes to begin to bind at the unison ring, but VGT functionality can be restored once the soot is cleared (but you still need to correct the source of the soot)
In my personal experience the above scenarios are fairly common when we come across a VGT that is "seized"
@@momentumworxthanks for the reply. Agreed on the soot/carbon buildup, but IMHO CTT’s VGT nozzle rings and shroud plates are famous (not infamous) for FOD resistance and thermal resistance. I believe those are a 300 series stainless and are heat treated for those specific forms of resistance. I’ve seen plenty of rip outs during rebuilds and more often than not, those nozzle rings and shroud plates get the carbon dissolved off and scrubbed, then go right back in. I’m more thankful for these than VNTs from those “other guys” lol.
Clearing up the cause for whatever causes FOD, etc - couldn’t agree with you more brother!
Keep up the great work. Love these videos.
@momentumworx how do you get the plate off with the 3 bolts in it after you remove it
About the EGR system, cause carbon accumulation in exhaust gases?
Obnoxious music.
I see you exercising that 1st amendment my guy. Enjoy!
@@momentumworx Good no BS analysis and comparison of your turbos.
What’s up with that annoying music?
