Leakdown Results on High Mileage Turbo

Engine

Vehicle Information: Year: 1991; Engine (Size, Modifications): 3.3; Total Mileage: 79,000;

I'm considering a high mileage (79k) turbo primarily for track usage. A recent leakdown using the Porsche Test Kit revealed compression readings as follows (Cylinders 1-6, in order):115, 115, 115, 115, 120, and 120; Leakdown on 1-6 was: 3%, 4%, 3%, 3%, 3%, and 3%.Is there any reason from those numbers to expect that it will soon need a rebuild? As far as can be determined the engine has never been rebuilt.Thanks!
