Check out the '87 Dakota 360 twin turbo test mule. Blast from the past. Man if only they'd built that one!
Putting a turbo on a magnum engine just isn't practical. In order to avoid damage you would have to really know what you're doing. Their was a post made on some other forum of a man with his dakota I think that put a turbo on it and well bye bye piston but I think he was expecting it to break. I can't find the darn post but I'll keep looking.

Anyway's the pistons in the magnum engine are fine maybe not for turbo application but I never put a turbo on my magnum though I thought of it hah. I think having forged wouldn't be a wise move for just a few reasons, one would be the weight it would probably put some drag on the stroke and the ECM would get confused with timing (possibly), another issue might be with expansion as the magnum engine was designed with aluminum pistons because aluminum expands over twice as fast as iron does so this ways the piston keeps it's shape and it's seal. Also the aluminum piston's were used to better distribute the heat from the piston. But just throwing a turbo on a magnum and that's it will damage the engine, it would need to be done properly to avoid the damage. Besides you can probably get more hp and torque in higher RPM's with other modifications besides a turbo which not to mention having an engine that can only handle so much boost.
