I have a KKK K14 Turbo that has been rebuilt by turbo technics using new bearings, seals and a new shroud.
The turbo will come in the original Turbo Technics box with all the paperwork from them. It still has the oil they put into it as well as the little caps to plug the oil galley.
As it came from a GTD it means the turbo is also water cooled. I'm not sure if you can run it without the water cooling for other purposes though. Apparently the K14 is the best compromise between the K03 and the K24 in terms of lag and boost pressure.
Looking for any offers as my GTD conversion is now out the window. I also have the auxilary electric water pump with pipes available. Turbo comes with temp sensor attached.
