These are good chargers But.... Make sure you get the comp. wheel pined, you can try it without but Ive seen a pile of the come apart. If you can make 55-60lbs with one of these Id say your doing something. I would also not push them any more then that. As for the waste gate Enginered Diesel has some nice set ups. I would suggest the adapter plate you will need with the gate plumed into it.
