You can turbo, but one the stock internals you won't get good results - plus I don't know any pre-existing kits for the truck. I would see if someone sells bigger cams, and you can port and polish your head. If you do anything to it you will want to get it tuned- that alone with the stock hardware will probably get you 20+whp.
