Alright, I got and swapped my 240 about 2 1/2 months ago. And it seems like every 2 weeks or so I am replacing the turbo gasket and studs, and or nuts. I use grade 8 lock nuts, not the nylon ones the reg ones. But at first the nuts would come loose, so i put lock nuts on there, that helped but they would still come loose. Or I would snap a stud some how. I've replaced every stud and nut at least 4 times by now. Finally I managed to find those tabs, so I put those on and the nuts dont' come loose, well kinda. The front two are still tight with the tabs. But I snapped another stud on the back so since there was no nut for that tab to hold the opposite side nut came loose and fell off. Does anyone have a solution for this? Potential problems: no torque dampener or flex pipe in the down pipe. But I know friends that don't have those either and they seem to not have a problem. Any help or advice will be greatly appreciated. thanks in advance.

Is your downpipe connected to the tranny with the hanger there? If not, that causes a lot of problems.
