Factory cut & welded center turbo manifold?

[T9000]

I bought a backup turbo center manifold on epay as I am planning to add a few sensors to measure boost and temperature as well as experimenting with water-methanol injection.

The part is listed as NOS and it came in a box with an AMG label, however it is about 1/2” taller than the one on my engine and part of the top it is cut & welded with the air impaler removed:



On the back, mine is casted with ACE CO1 and the new one with ACE CO2.
I checked the parts TM and it does show the RCSK17829 as the center turbo manifold.

Is this one for a different engine?
I don’t think it even fits on my truck as there is very little room at the top.

Is this an actual AMG part with that cut & weld?

The port sizes look slightly different as well.

The one you bought was an early non GEP cross over, it had to be modified in later models for clearance, why your GEP cross over was designed lower.
If I had one of the early types that was modified I would seek out the GEP (black) cross over, although it may not actually make any difference.

I’ve seen these on Early turbo motors, IMO, it was done before they started doing a minor body lift…I’ve had numerous of these crossovers.
