He341 turbine housing.

Are you referring to the turbo from a 2003 or early 2004?
Or are you referring to the HE341VE (VGT) turbo?

If you're referring to the 2003-Early 2004 version, AFAIK, the exhaust housing is the same as an HE351cw, both measure 9cm2 and align the same way.

Now, I know the BEARING HOUSING is different between the 351 and the "341", since the relief that the compressor wheel sits in is bigger on the 351.

Mark.
 
Yes im refering to stock 03-04 turbo. I thought the turbine on the 351 was also bigger, not just the compressor.
 
Well, I have measured the turbine wheels between a 351 and the "341", they share the same assembly.
As I mentioned before, even the turbine housings both measure the same, at 9cm2.
The difference is all in the compressor cover, the compressor wheel and the bearing housing.

In fact, even the '01-'02 HY35w uses the same turbine/shaft assembly, but they DO have an oddball exhaust housing that resembles an HX35w, in that it uses a bolted-on back cover, instead of a band clamped cast elbow.

Mark.
