Spencer- you have what is called an H1C holset, I never got a chance to measure the wheels on it, but it should have a 58mm exducer or might even have a 55mm exducer on the turbine. Maybe you can get the wheel measurements?
Russ- if you have a hy35 it will have a 9cm turbine housing on it stock, the he351 has the 12cm housing. I believe the turbine exducer is 58mm, it might be a 60mm though. I might go out and measure my hy35.
