So only 1999 engine will be compatible to mine ?

The problem is that Porsche never leaves anything alone for long. The 99 cars had no CAB Bus, the 01 cars used a partial CAN Bus for DME, dash, and other controllers; by 2002, most of the car's systems were on the CAN Bus network.
The VarioCam system also changed, at first being a single move of around 25 degrees, them became totally variable (VarioCam+), and then added variable valve lift to the system.
I would limit the search to a 98-99 engine to be on the safe side, unless you are ready to fund a lot of "one-off" custom systems fabrication, which ultimately reduces the car's resale value as no one but the person the made it work will know how to fix it.
