Hi Matt, welcome on this side! So you're the one who just bought it from ebay!!
Congrats.
CSL engine is optimised for the larger volume of air that's being sucked in so intake and exhaust camshafts are longer duration. 280 in and 272 degrees out. Also, the exhaust valves are optimised too.
The lift remains the same at 11.5mm just the duration is a bit longer. If you're going to go for cams, go for Schrick 288 / 280 but stick with 11.5mm lift or CSL ones. It's worth it IMHO. I am hoping i'll achieve 380bhp with mods i am installing.
By the way - I am buying low milage CSL engine (£1500) right now so maybe just buy a second hand engine?
Good luck!
