turbo question

[gobcumminstruck]

what is the differets between an holset h1c and wh1c turbo? and well the inlet side from h1c fit on an wh1c? i find were it an wh1c needs rebuilt, the wh1c has exhuast housin and wastegate comes with it. i also find were theres the middle been rebuilt i may get it put i need inlet side thats why i was wondering

[skilletky]

the w in wh1c means it is wastegated

HOWEVER......there are two diff. h1c turbos.

The Non I/c trucks have a smaller h1c on the compressor side.

The baby h1c.


50mm compressor.

A true wh1c has the same inducer as a hx35,which is 2mm bigger than a h1c at 56mm vs 54mm.
I've got one tore apart in a box

[gobcumminstruck]

so i take that as no. and how u measure the housing to know what it is??

[ellis93]

I measured the ends of the turbine blades to find out what it was. I had the same thing told to me,that the wh1c was the same only to find out it was the same as the hx35. I don't know about the baby h1c but the turbine shaft interchanges with the wh1c,h1c,hx35,hx40(older) turbos,least thru all of my digging thats what I've came to understand. I bought all my rebuild stuff from gds when I was building my hybrid and even the guy there said the same.

I can dig up some old pics of how I did it if it'll help you out

The turbine housings are interchangeable......the compressor side is what is different.
