Kinda fused in from the heat. I'm working on getting them loose and really dont want to remove the turbo but i might have to.
by "clocked wrong," i'm assuming you mean the CHRA is off by a few degrees (kinda like timing belt/chain can be off by a tooth or more)? if so, i didn't even know that CHRA's had to be aligned like that. i just figured that if you can't detect any play in the CHRA indicating that the rotational axis is off-center, you're good to go (correct me if i'm wrong). are you confident that its not just some bad or mis-seated turbo seals?

yeah, that would be my guess too, seeing as how a V-band doesn't use a gasket of any kind to rely on for a perfect seal.



anyways, can't wait to see this thing running 100%...don't forget to make some videos.
