I beleive the T5 is rated to 340 TQ, so as long as you aren't doing a lot of power shifting it should hold up for quite a while. Mine lasted 4 years behind a 365HP 400TQ 350.

Yes we have to deal with some smog, but no sniff test. My car is 100% emissions legal, for the record. But, whenever I take it in to get it checked they never check anything, they just gawk at it and ask LOTS of questions. EVERYONE in the shop always wants to take it out for it's road test.
