When going turbo what alternator and tensioner do I need. Like off what engine/ year

 

Any of the other engines. You need the belt/tensioner/alternator from a 2.2 or 2.4 or turbo 2.0. They all use the other setup.

You can keep the LSJ alternator, but you'd need to lock the pulley to keep it from not spinning enough due to the one-way clutch it has. Some people just tack-weld them and leave it. You will still need the non-SC tensioner though.
