930 "wastegate"


Vehicle Information: Year: 1989; Engine (Size, Modifications): 3.3L; Total Mileage: 36;

Hi , I am replacing my original turbo wastegate with an after-market unit. My "shop-manual" calls the two "hard-lines" to the wastegate , "control-lines" ? Are these "vaccuum" , or "manifold-presure" lines? Is there any oil that circulates thru unit? The reason is that, I will have to "splice" into the factory lines , as they are positioned slightly differently on the new unit ,and I will need to know in advance , the nature of these lines , so I can "splice" them in accordingly. Also , my car is equiped with the " One bar" boost spring. The spring itself resides inside the OEM wastegate? thanks in advance
