HobbyKing carries the Trackstar engines with the red cooling heads and the EG Sport engines with the black cooling heads. Mine is a Trackstar and it has a turbo plug. (Evidently some were not turbo plugged)The EG Sport engines use a regular plug. As for the displacement, I also saw in reviews and such that the displacement was not as advertised but I haven't measured mine as I don't really care. Parts might be difficult to get as Go is out of business so any parts you need might be new-old stock from somewhere.
