Yes the turbo will bolt up exactly the same to the engine. The only problem he will run into is, the 16cm exhaust housing is a little shorter by about 1. 25in" because there is no wastegate. He can either 1) extend his exhaust system or down pipe forward, or 2) buy a ready made 1. 25in exhaust housing spacer from Diesel Injection of Pittsburg. Or if he's replacing his exhaust anytime soon to a 4", then he won't have any problem fitting the down pipe a little forward to make up the difference.
