i have a 3.4 v6 camaro and i really want to keep the motor but turbo it. is there any way i could put a single rear mount turbo on it with out major modifications to the motor

 

Sure. You can rear mount a turbo, or mount it under the hood. Rear mounting keeps heat away from the engine room, but costs more, and of course is more complicated with piping. If your engine is stock, then the compression ratio should be low enough to turbo without any mods.
If you plan to boost the turbo much you will need to do mods to beef the bottom end of the engine up, but if you keep boost down it should handle it fine, if the engine is solid.
