Sure it would. Just keen an eye on them to make sure they aren't exhibiting any signs of running "too hot", but in my motor running 1.2bar of boost, they are working great.

My original post above suggests the author of the article was having great success even running FR6DTC's on his "hard run turbo motor", so the FR5's would be fine as they are a heat range colder than what he's running.

The later model twin turbo's such as 993TT's and 996TT's all run the FR6's
