It's not only the transmission that doesn't like much more power than stock but the differential and halfshafts. It's also a non-intercooled factory setup. I cannot really think of any other turbo or supercharged factory setups without an intercooler.
The GSX comes with a 3.5 pulley which is a very minor pulley change from the stock 3.8. When most people start modding the L67 they usually start with a 3.4 and a few other mods to combat knock retard.
