3D Models

Hey guys, i'm looking for 3D Models of Mercedes M111 cylinderhead or M111 exhaust manifold.
Would be also really nice if anyone got a model of CLA/ A 45 AMG Borg Warner B03S turbocharger like OEM article number A1330900408 / A1330900280.

I can edit .stp, .iam .ipt .sldrp .sldasm

If anyone could help, it would be really nice. Want to prototype for car.

Thank's at all!!!
