Do you mean the blocks of wood that came with the kit? A few modified them to mount a turbine. You can look back in this thread to see how they did it.
Regardless of what you use for a mount I suggest that you put the engine at 5 degrees and lower the engine as much as possible. Mine almost touches the rear of the engine shelf. Also that shelf needs to be reinforced. I suggest that you read this entire thread before starting.
