Rotating T34 compressor housing?
I need to rotate the compressor housing 90 degree's, how does one go about it on these turbos? Most I've had experience with use V Bands in the centre!

I had to do this recently with my new turbo. Was told to loosen the 6 bolts that hold on the 2 plates in the pic, 1 being where to attach the RS500/original damper, then just rotate the exhaust housing to whatever orientation your exhaust manifold is.
As far as I know, it's the same procedure for the compressor housing, loosen the 6 bolts, rotate and tighten the 6 bolts.
Hopefully someone else can clarify as never did this before.

Are we talking about the ones that are on the compressor housing itself?

You have to rotate the exhaust first so the core is upright (oil input at top and outlet as close to vertical as possible) tighten it all up and the do the same with the compressor housing.
Before doing the final tightening, fit the wastegate actuator. This also has to line up to the wastegate control arm.
The plates that you tighten with the bolts have the same effect as a v-band. Once all are untight, the core should rotate freely

Do we have any recommendations on getting them loose? They're FT! Open end spanner just seems to want to open up.

The ones on my turbo were siezed too,
I tried with WD40, left it on for a week, but it did nothing
The last resort was heating it up with a blow torch.(turbo on workbench-vice )
Be carefull of the ones on the turbine intake, they need heating from the inside for best results as they are surrounded by too much metal and heat dissipates quickly (as its supposed to)
EDIT:P.S. If the bolts are seized, the core will probably be siezed to the housing too. I held the housing on the vice, and tapped the core with a hammer gently and evenly all around (paralel to the turbo shaft, hammering onto an extension bit - not directly)
Dont forget that hot things can burn your hands (and whatever you do, do not -I repeat - DO NOT pick up the bolts of the floor like I did
)

Got the bolts done, one needs replacing now. Core is well and truly seized though!
