You need to measure the wheels. I'm sure Bison will chime in. He's really good at this game.

The compressor housings and exhaust housings are all about the same size. They machine the insides to match the wheels. You need to know the sizes of the wheels in mm. That will tell you the combo.

Sometimes the turbo size will be scribed on the compressor outlet.

post pics of the wheels. Measuring the wheels will give a definite answer.
