with a good hg and arp bolts and proper torquing, the engine will hold up to almost anything. and if it is a turbo engine the compression will be better suited for a tt.
twin turbo wont really help the 7m unless you have sufficient suppporting mods and good turbos but you wouldnt tt a 7m if it wasnt ready for it.
