But this is my first watercooled boxer six so this is new to me, But I suppose itīs also have to do with valve size and cylinder head intakes etc...
What is the win?
My engine will just have sport air filter, race exhaust manifolds and 200cell cats, nothing more at the moment.
On the 986, there is a pretty big discrepancy between power outputs for the 3.2 and 3.4 motors, which with all else being equal is likely due to the much smaller intake and TB between the 986 and 996.
The 987 airbox is much larger than the 986, and has a 3.25"MAF hosuing already, so you would just need a 78 or 82mm Bosch TB and the 996 intake plenum/runner.[/QUOTE]
