I'd assume you could use the TB's from the 300, however, I think you'd have to do something about secondary butterflies. Like remove them. If it's like the EU 250R TB's, it's a dead-end fuel rail instead of the version ecotrons uses with the return line, which makes the plumbing easier.

My only worry about using TB's from the 300 is the injector size. What is the ID of those TB's? 32mm?
If you wanted I could get my caliper out and measure the opening end and head end.
