N/A 944 camshaft - an upgrade for a 951?
Hey gang,
I heard a rumor that swapping a N/A 944 cam into a 944 Turbo yields some sort of power gain or performance benefit.
Is there any truth to this?

Not sure about performance difference on Turbos, but the on the NA's the late cam is prefered vs the early cam. The Turbo uses the early NA cam.
Here is alink to Danno's Website on the cams.

Nah, not worth it. The only difference is on the exhaust lobes. What you really want is a later closing on the intake.
Even the mildest aftermarket cam, the Webcam #274 that's part of the Kokeln-363 kit creates a Dr. Jekyll & Mr. Hyde type of powerband that's completely dead down low with tonnes of turbo lag, then it hits all of a sudden around 4500-5000rpm and slams you into the seat.
The more radical aftermarket cams like Millege would probably yield a peaky power band that's really only suitable for a race car (around 6000-8000rpm).
A cam upgrade should be one of the last things on your car. The cam profile should be custom-ground to match the turbo you're using as well as the flow characteristics of your upgraded intake and exhaust systems.
