Can someone identify this Holset turbo?

[AndyMan]

On the truck I recently purchased is a rather strange looking turbo. Every time I pop the hood to give someone a looksee, they all say the same thing: "that ain't the stock turbo is it?".



Here's a pic of the dataplate. No pics of the turbo itself. Compressor side is black, turbine side is rust just like all others. Truck is a manual trans.



In case you can't read it, the tag is as follows:



Assy. 3533320

Serial: C0296353

Customer: 3925740-0-09/3

Type WH1C



Thanks,

Nebbermind... . It appears that this is the turbo used on the 1994's. I thought they were all HX's or HY-35's. Evidently first 12v's had the WH1C.



I guess that settles that.



Thanks,

I believe that is a 12 cm housing.

is the truck a 94 or a 95???

The WH1C uses the same exhause housings as the HX35's. If it's wastegated it's most likely a 12. The earlier (1st gens) came with bigger non-wastegated housings.

The WH1C and early hx35 was basically the same performance wise.

The difference is that the WH1C uses a band clamp around the compressor housing instead of the snap ring that the HX uses. Cost cutting...

my HX40 was built w/ an H1C core... v-band compressor. SO much nicer to work with/clock than the snap ring!

i second that a snap ring sucks to mess with the vband is better. .
