Have you ever designed a direct injection turbo engine before? Do you have any idea how difficult it is to size the turbo? It's waaayyyyyy harder than picking something for a custom project or a kit sold in small volumes. I have seen guys who size turbos for a living get it wayyy wrong, surging at low speed and choking at high speed. That kind of mistake can cost a supplier huge contracts when they fail to meet targets. Have some appreciation for what's involved in making that kind of "truck" torque curve. Coincidentally, the new M5 and S8 have a similar curve, although high output spec DI engines do rev a bit higher. Also, BMW and Audi have 2 liter turbo gas engines in their sporty cars.

The FA20DIT is a great engine for a family car (Legacy) or truck (Forester). Am I disrespecting the notion of putting this type of engine into a sports car? Yup. That's all. I do believe when/if the wrx/sti are released in the near future with their version of this motor it will address the issues I have with it's unsporty nature. There is more to a fun motor than pushing your butt into the seat. I'm not dissing all turbo motors. There are lots of great examples of awesome gas turbo motors for sports cars... ej2xx, 4g83, sr20, etc. I'm not sure I'm sold on stand alone DI for turbo cars yet with all the issues people have run into on the VAG/BMW side of things.
