They do look like real copies of the pentroof manifolds but i wasn't sure about how long ago they were made,yes it could be around 5 years ago.Do you have any idea what turbos they were designed to use? I bolt the stock turbo to them with some modification but it would required to make custom piping since it pushes the turbos slightly out more than the stock manifolds and more to the back to clear the engine mount brackets. It would make a really good engine built project but only for people that have the time, since alot of things would have to be relocated in the engine to make it work right.
