yes..therefore a lot of US T-Duos where sold in europa as import goods.
btw. found a good chapter about the development of the engine on watarus site. they also discussing about the growup of the US TG etc. briefly, they say that the PCE was made of longterm proven PC-parts and therefore the size could be minimized to its max at that time. in japan they liked the small design of the white core, but for oversea sale it might look like a childs toy, so they pumbed it up. since they had more space available, they also changed the mini-DIN plug to the normal DIN, for robust reasons.
will translate the important parts later
