engine ???

i just buy a 911 T targa 1971, i have surprise everyday...
the engine # 901/03 9547 *2080005*
is this 2.2, 2.4, 2.7 or ...help me
blue smoke 5 minutes after start and back-fire, running good when hot,
weber carb., the car is stored two year before,
thank you
PS excuse me for my english (french-canadian)...

Raynald,your engine is none of those from your list - it is in fact a 1968/69 2.0T !
As the numbering sequence for these engines started at 2080001 this makes your engine the 5th 2.0T engine in the production run.
In standard tune these engines produced 110bhp at 5800rpm.
Hope this helps.
