Bad news
1) Complete front timing cover assembly from your block . (power steering is different on CL and S)
2) Oil pump and both oil pans.
3) The blower inlet on the CL, has a different adaptor for the CL`s vacuum brakes. I think you can sawp your fitting, unless you have a modified inlet to use.
4) You also will need your rubber plug for the intercooler line just to the left of the blower.. The S and CL use that line and the E`s do not..
All the heads, block, blower, pulley`s,intercooler, water pump,coils, injectors, other vacuum lines, are the same..
I may have missed something but this should be damn close to everything. Front motor cover and oil pump/pans are the main things.
