You'd have to change:

- Muffler inlet flange to a GT 4 bolt, or just weld a 3" v-band on it and be done with it. A V-band interface will allow quicker/easier removing of the muffler, instead of stuffing around trying to access rear bolts etc.

- Oil drain flange on the GT is different to the KKK

- GT turbo has a 2.5" outlet on the compressor side, so you *may* need a reducer if your KKK has a 2" outlet.

- GT turbo has a 4" inlet to compressor, but you can get the supplier to CNC it down to a 3"-3.25" to make it easier to mate with your existing air intake pipe depending on what size it is currently. You may need a silicone reducer there too.

- oil feed line for GT only needs a -4AN, otherwise you'll over-flood it with the existing oil feed line I'd say.

Hope that helps.
