Garrett turbine housings

[blown 944]

Hello,

New here and I looked back but did not see a thread regarding the use of Garrett turbine housings with Holset turbos.

I have been experimenting for the last couple of years and have found good results using the P-trim housings for the larger wheels and the stg 5 housings for the hx35 turbine wheels.

There is minimal modification required to get the housing to fit the turbo.

1) the bearing housing along with the  heat shield needs to be shaved down slightly where it meets the T- housng
2) on the p trim size wheel you need to polish out the mating area of the t-housing so the wheel will fit through.


I have used both  with some success on my Porsche 951's. My current DD has an HX 35 using a .48 T4 twin scroll t-housing and spools at 3300 rpm and makes some pretty good power.

I have also used a full HX 40 pro wheel turbo with a  .58 T4 housing to make close to 500 rwhp at 27 psi. I have ran more pressure but not dynod it.  

Thank you for providing this site and if this has been covered please feel free to delete this thread.

Well thats good to se some one has done what i have done. I have done what Sid has done for some time
machining the bearing housing flange and heat shield down and the depth of the recess fot the heat shield. Have bored out the turbine bore and touched the profile to sought copping the Holset Turbine Housing. I have used the HX35 wheel and HX40 wheel in a Garrett singel entry turbine housing A/R .48 and A/R.63 .Using the 54mm inducer comppressor wheel. And have also had the turbine housing ceramic coated. i will post the photos and performance specs on a BMW 318 and BMW325
