Lonx: The intake cam actually opens the valves for 248 degrees, as opposed to the standard 240. It also provides 0.8mm more lift, bringing it up from 7.8mm (max valve opening) to 8.5mm.

The exhaust cams however are the same. I'm not sure, but I've heard it is good for around 5 - 10kw, with gains almost completely across the rev range. I have one of these cams lined up for my car and besides a set of bearings its basically a 'drop in' job. I'll let you know how it goes.

Lumpy: the camshaft swap is pretty easy. there are no specifics for the upgrade other than careful adherance of the factory procedure for the belt removal and bolt tensions etc.

There is no need to worry about bearings as the camshaft doesnt have any.

As the engine uses an air flow based fuel metering system, there is no need to worry about tuning fluctuations with the cam swap. The stock mapping is beyond adequate in this regard.

The swap will give a very slightly lopey idle - although hardly noticable.

when used with a larger turbo and free flow exhaust, there is no loss of power with a noticable improvement in the mid and top end performance.

The CA18DE cams are mid way between the CA16DE and the CA18DET.
