I think sho shource used to list them. I'm sure they might be able to put one together maybe. It's the piping that's the issue. Most turbo SHOs I know of were 1 off custom jobs. You will also need someone to tune the thing and this will be obd I tuning not the normal OBD 2 computers. In addition fuel injectors, higher flow fuel pump etc.
I would not turbo this car unless you have other transport and access to used replacement transmissions and other things. SHO Source is located out of WA so they are not geographically that far from you.
Here is a supercharger kit for the MTX maybe they can give you info on how to attach to atx cars. Should not be a huge deal
