hey whats up im new to this and this is my first time doing this but ive heard that the atts cant take alot of torque either. h series motors are pretty powerful if done right. whether or not your engine is in great condtion you shouldnt run a turbo with a stock engine. it may hold up for a little bit but not for long then youll be into serious money issue!! unless you got money to burn like that. pay the money and do it right. i did its expensive but well worth it plus to be on the safe side. i switched my tranny out with a 92 non vtec si . 1. for closer gears 2. a quaife lsd . when your putting out alot of power the stock atts is just gonna let the tires spin and its gonna look embarrassing. there are turbo kits fo r the sh models just make sure you know what your getting into -later
