The new 911 turbo's have a rediculous 0-60, watching them launch with the sequential box is like watching a ninja kill you. Don't get me wrong it is a good engine design for certain reasons but in the grand scheme it isn't the best. It is much more useful in a Porsche due to the rear engine design, a front engine awd vehicle doesn't need a boxer engine. Case and point the EVO, which when it hit the shores and competed with the STI, beat the STI at everything except for sheer power and acceleration (the STI had an extra .5L to work with). The newer EVO's are gay IMO but the last of the 4G63 equipped cars were a force to be reckoned with.
I think the boxer engine is necessary in a Porsche, I think Subaru just uses it to be different, if they had Inline engines they would be the same as everyone else but not quite as good and hence run out of business real fast. They know boxer engines, no one else other than Porsche does, so they stick to it to give themselves a niche to survive in. But there is a reason NO ONE else uses them, Toyota is just capitalizing on that niche with the FT and hopefully using some of their amazing engineering and quality control skills to make this engine more reliable.
