1998 Impreza Outback Turbo Swap

I'm just basing that off what I've read, never done a dohc swap in an ea81 body. I have done a basic ej22e in a brat.

I was just wondering if it was possible. Usually motor mounts have enough excess stud length to allow a few spacers if needed. U-joints can typically tolerate it as can trans mount if the movement is small. Was just thinking it'd be easier than notching if it worked.
