Solved Pessima V6 into 200BX Coupe engine rotation

Hello everyone, I am attempting to place the V6 engine from the newer Pessima into the 200Bx. I have managed to swap over the textures and engine, but I cannot figure out how to rotate the engine. An older thread mentioned replacing the term "pos" with "rot", but I encountered 2 problems with this. First, if I attempt to place a rotation value separate of the "pos" it an error and the vehicle no longer functions. Second, if I simply replace the existing "pos" with "rot" it rotates the mesh relative to the vehicle I believe, not in place.
The current Jbeam I have is this :

"flexbodies": [
["mesh", "[group]:", "nonFlexMaterials"],
["midsize_engine_v6", ["midsize_engine"],[]{"rot":{"x":0,"y":0,"z":90}}{"pos":{"x":0,"y":0.2,"z":0}},
],
"nodes": [
["id", "posX", "posY", "posZ"],


Thanks for your time, any help is greatly appreciated

 

Surely it would be easier to make a copy of the model and rotating it in Blender?

 

Like this? It's much easier to do it in Blender.
