I may have a 12cm

Spenser i have a Holset HY35.

I wouldn't mind trying a different housing eventually.

R.mojica: I'm assuming you have the 14cm housing on yours too?

I'm not sure how to tell. it has the 4" V band outlet. I would love a 9cm housing if mine is bigger.

Oh ok - mine has the 4 bolt flange like the stock turbo. It was at a slightly different angle though, so I ended up converting it to a 2.5" V band.

ohh ok, mine is 4" turbo back and out the side. ill look into housings on break today. I was looking into billet comp. wheels as they are lighter with different blade designs and will allow for faster spool.

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.

My mistake, Noted for future reference.

If I have it apart again, I'll measure it.
