7MGTE engines are pretty cheap to come by. Give the thing a GOOD going over before you put it in the car. IE all new gaskets, get the head refaced if needed, Metal head gasket, do a search and im pretty sure ull be able to find the proper torque settings, use new head bolts (im pretty sure its 82lbs but double check it first!) the stock head bolts are what makes the fuck up.
7Ms are tough engines my a dude in my car club has one putting out something like 380rwkw out of his one? pretty nuts, puts 2jz's to shame
best of luck!
