1) Did you have to increase the belt size to accommodate the extra idler pulley?
2) If you did not increase the belt size is there a concern about too much belt tension causing premature belt wear as well as extra tension on the bearings of other idlers and components being driven by this belt? The belt seems to have some pretty good tension already.
Thanks all.

1) If you're using the stock Stillen belt then that belt works fine with the TopgunZ (sti) pulley. If you need the part# for the pulley, let me know. If you use the Tbatt kit, it comes with a new belt.
2) There is a stock nissan tensioner that provides the tension on the stock serpentine system. It will compensate for the extra tensioner pulley. It will be a tight fit but I haven't had or know of anyone that's had premature wear on the other pulley bearings with the additional tensioner pulley.
