I want to find out if a particular Turbonetics turbocharger I anm considering ,is a "Big Shaft" turbo (therefore being rebuildable) or whether it is a standard shaft, unrebuildable unit. it takes a 17mm socket to fit on the compressor side wheel nut. -not sure if that indicates anything of use???

If anyone could tell me how to determine the difference, I'd really appreciate it.
I've read through the stickies (great info there!) but didn't find anything pertaining to this.

Standard shaft unit is 1/4" @ the quill (shaft threads)
Big shaft unit is 5/16" @ the quill (shaft threads)

so if it's 1/4", it is therefore NOT rebuildable, and if it is 5/16", then it IS rebuildable???
Is this the only criteria needed to determine rebuild-ability?

If it is a 1/4 shaft you can get a rebuild kit but if your if you need any hard parts like bearing housing and turbine wheel it will be hard to get parts for it.

Yes determining what turbo you have can be the telling factor if you can get it rebuilt.
