Im gonna say that yes it will bolt up but you have to use a mix match of parts for the clutch n flywheel. If I remember correctly. The g54 2.6 liter is a wide block just like the 4g64 2.4. The g63b 2.0 and 4g63 2.0 dohc are narrow block. If you search around here in posts and the wiki youll probably find what youre lookin for. Also try projectzerog.com
