All I did was push the motor far enough forward to allow enough clearance, but I left myself a little more room than I needed, so the redesign of the mounts allows the motor to move back about an inch. The mounts leave a little room, about 1/2" to adjust it forward or back. You just need a hard bend right after the turbo, not ideal but it woks fine, I will put up better pics tonight and show you what I mean. I don't have any heat shields and everything seems to be fine, but it would probably be a good idea to add one.
I have also seen a thing they call a "Cobra head" which is a cast iron down pipe, that looks like a cobra head, but it does not look like it flows well, but it is an option, it would probabl give you anothr 1-1.5" of clearance
