Ive seen guys have all the hoses in the engine bay swapped out to another color, however i can never seen to find these anywhere online.

Anyone happen to know where to find them? Or perhaps know the name of these hoses?

 

You mean like this? Its called wire loom, it just goes over the stock wires/cables. They come in various colors

 

A lot of guys buy non specific hoses that are colored and cut to length, otherwise they wrap them like shown above.

 

the only hoses that appear different in the photo you showed are the radiator and supercharger hoses. OBX, Mishimoto, Samco make radiator hoses in different colors of the tC. The supercharger hoses are probably Samco universal pieces cut to length, unless someone makes a kit for the supercharger.

 

If you notice, there are red arrows pointing to the black hoses. Those are the hoses in question. The wrap idea is cool, didnt know about it, but im looking for a hose replacement.

If I have to get my own and cut them, what sizes woudld I need for the hoses pointed out in the pic?

 

I have a supercharger kit rebuilt with reinforced brackets ceramic bearings and the stock ones nst 9.5 pulley full kit mounting equipment screws everything ready to put on asking 2000k or best offer the supercharger has no shaft play due to the rebuild it's basically brand new just trying to get rid of it ASAP and the trd exhaust was on the car for a year or so looking for like 200 also for the supercharger I have the greddy emanage ultimate tapped oil pan 440 and 550 injectors have reinforced brackets I put a lot of money into this build
