Agree with Frank993 c4s, they should give you numbers. With compression, all six cyl should be close be high or low. Ie its better to have 6 at 115 than 5 at 130 and one at 110. On leak down 5% or less on each. again, even is better

For some reason when I posted a note in reply it went to another thread. So start again, Compression numbers should be even or close be they high or low. all 6 at 115 is better than 5 at 130 and one at 110.
On leak down you want 5% or better on all 6. Again even is better.

Once I get the car it wont be long before its up at a Porsche specialist in Brisbane getting a proper look over and some freshening up. The owner told me he had put 5000km on the car in 6 years, so im guessing most of the leaks are dried up seals. Because the car is an import its value wont hold like an Australian delivered model so I am not too concerned about keeping it as stock as possible (it already has coilover suspension and a RUF exhaust), so a 3.6 motor swap might be in the cards if its current motor gives out.
Thanks for all the input guys, it has been very helpful. Now your going to have to put up with a lot of newbie 911 owner questions! I already have a decent list of parts ready to be ordered and I am looking forward to spending many hours getting the car back into A1 condition.

On a cold motor, leakdown of > 20% on a 3.3 Turbo motor is what FBR considers to be rebuild time. Got the impression from talking to them that an average motor was in the 10% range when tested cold.
