Vindicare Posted November 6, 2008 Share Posted November 6, 2008 Hey guys, I had a quick search and couldn't find what I was looking for. My question is, Does the oil supply/drain have to be vertical for it to work properly? Reason I ask is because the Turbo manifold I have sits the bearing casing on the horizontal plane. Also. Is it possible to change the orientation of the compressor housing on a Holset hy35? I need to turn that also 90 degree's. This Manifold is starting to give me a headache Aaron Quote Link to comment Share on other sites More sharing options...
RB26powered74zcar Posted November 6, 2008 Share Posted November 6, 2008 I've never seen a turbo you couldn't loosen the bolts and clock it how you need it. The oil inlet/drain should be as close as possible the vertical, but can be off slightly... Quote Link to comment Share on other sites More sharing options...
rossman Posted November 6, 2008 Share Posted November 6, 2008 Yes you can clock compressor on a Holset. You need to separate the housings and grind off the little clocking nipple. It will be obvious when you take it apart. Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted November 6, 2008 Share Posted November 6, 2008 The locating pin you are referring to can be pulled out of the hole it's pushed in. It isn't necessary to grind it flat. The turbo must have the oil feed and oil drain within about 10~15 degrees of the vertical axis to avoid oil leaking past the seals. The situation gets much worse if the CHRA axis isn't horizontal as well. Quote Link to comment Share on other sites More sharing options...
Vindicare Posted November 6, 2008 Author Share Posted November 6, 2008 Cheers guys, someone had already removed the pin so I just loosened the clamp and spun it to the right orientation. Thanks for all your fast responses. Aaron Quote Link to comment Share on other sites More sharing options...
