if i convert a automatic shell to a 5 speed and cut off the mounts of a donor 5 speed and re weld the tranny mounts on a automatic shell. How much horsepower can the new welded mounts take before breaking. Will it be safe to turn the car to a turbo 2 or will it not be safe? thinking about a 500 hp turbo 2

so welding the mount should be good. by the way this car will be use for drifting comps. nasa racing events and mid level touge mountain racing. So really dont want the tranny to break and fall when racing in the mountains

Yes, welding the mounts will work as long as the welder is good.
+1 on the no adaptors, welding in new mounts is cheaper, easier, and stronger then any kind of backass adaptor crap.
