What is the difference in the center parts? Found a deal on a new WH1C center bearing housing with wheels. I got it today and the tag says H1C. I have a WH1C in the garage now and another whole turbo that needs work on the way. Basically the plan was to swap parts onto the new center and go. If they are the same and the only difference is the MWE slots or in the housings then its no big deal. If there is something that will prevent the swaping of parts or cause a problem down the line let me know to I can get back with this guy.

 

I'm not sure if you can interchange the h1c and the wh1c. The wh1c is the early version of the hx35, they only put them on 94 and 95 model years but they are nice because they have the band clamp to hold the housing on rather then the dredded c-type clip.

 

Yep. A WH1C is an H1C with a wastegated turbine housing and MWE slots.
