RS vs C2/C4 camshafts ?
Hi,
I just bought a pair of C2/C4 camshafts in CA and have a pair of RS camshafts at home.
I have to assembly an engine now and wanted to know if the camshafts are different. If the RS are a bit more agressive, I will have to wait and use them.
Can someone tell me that ?
thanks

From the tech spec book on the RS:
"Intake lift has been increased from 12.0 mms to 12.5 mms and exhaust lift from 11.0 to 11.1 mms. The valve timing must be set using special tools 9551 and 9552.
The two chain sprockets and the driver flanges are made in one part. Different parts are therefore fitted on the left and right sides.
Tightening torque: 20 Nm + 1 X 90 degree turn.
The tightening procedure for the two chain sprockets has been changed. When tightening, special tool 9582 must be held against the chain sprocket to relieve the stress on the chain drive"
I also know the cam has a 288 degree duration... the other specs.. sorry no got!
My engine is more pointed than the 3.8 X 51 optioned car of my friend. Idle is set at 960 ISO 800 +-40. Lumpier engine too... different cam is quite obvious. Hope this helps.
