Can't clock the turbo... Help?
So i picked up a mitsu t25 and im trying to clock the center to turn the drain downward and the compressor housing back to the top. But.... it's stuck! The turbo has never been apart and is out of a 98 talon. I have Break away on it and tryed the backing out of the 4 bolt against the center cast and still no luck?. Anybody have a good idea what next to do? Oh and its the style with the long neck on the compressor housing if that helps (not my pic) but like this with the wastegate removed.

So, you have the 4 bolts and the 2 clips off.
Do this:
Remove the compressor housing.
Spray the mating CHRA/Turbine mating joint with PBBlaster and let it sit for a few hours.
Put the whole thing in the freezer overnight.
In the morning, remove and clamp the CHRA in a vice.
Hit the turbine housing with a torch for about 5minutes... some light tapping is all it will need.
Make sure the CHRA is clamped in tight!!!

The compressorhousing/CHRA/turbinehousing are 3 independent pieces that don't care at all how they are in relation to each other.
There are only 3 things that have to match. The turbine housing is going to be in a fixed position relative to the manifold. The CHRA must connect to the turbine housing so that when mounted on the manifold, the OIL INLET/OUTLET is vertical. The compressor housing must then mount to the CHRA so that the wastegate actuator is in the correct position to connect to the flapper.
If you need the compressor housing in a specific orientation for the outlet pipe... IE, you need the outlet to aim down, you may need to purchase/fabricate a bracket to mount your actuator to so that it will actually actuate.
The good thing about the DSM actuator is that it mounts to the back of the compressor housing. You can mount it anywhere on the back of the housing you want... just drill and tap new holes. I run a DSM actuator on my Nisan turbo cause it was so easy... you can drill/tap the back of any compressor housing and that thing will fit. Compressor housings or actuators that mount the actuator to the front of the compressor are much more limited in what you can do.

The one in the pic is exactly what I use. I was able to clock mine ok with the oil drain down but I had to remount my actuator at a different location which as stated is quite easy. Drill a couple of new holes and tap them. Use loctite when bolting back on.

Sam, is this the magical DSM actuator you speak of? This install would be a ton easier if I could clock my T25 however I please and fix the wastegate bracket later...
