1998 Bonnie SSEI Engine Mounts
I am starting to make modifications on the supercharged engine on my Bonneville. Wondering if the Stock engine mounts will be enough or what other people have done for a stronger more solid setup. Im not planning on going too crazy with Modifications much more than 325ish Horsepower. If there is already an existing thread someone please point me in the right direction?

Never really had an issue with my mounts. Just buy some new ones, fill em with window weld and change them whenever its easiest.

People usually replace the front transmission mount as it tends to let go even at stock power levels. Other than that though, you're fine.

Drill a hole through the front trans mount and put a grade 8 or higher bolt throught it. It'll keep it from pulling apart.
If you want to go beyond that, window weld or urethane fill the passenger torque axis engine mount as mentioned. And Rodney Dickman makes an adjustable dogbone mount for v6 Fieros that is a drop in replacement for the passenger trans dogbone mount. There's nothong easy for the driver's rear trans mount.
