Thanks for taking the time to do this. Helps a lot since I will be changing cams sometime this summer. I know someone that might have some gsc s2s for sale soon. Might have to buy them after seeing this.

Great update, good to see the new hks 272/278 up there for the IX. Quick question, how does duration of cams affect power band and agressiveness/driveability? ie. kelford 272/272 and the new hks 272/278, more duration for hks but similar lift. What would be the difference between the 2 when installed? Stock IX turbo in my case...

Good question, lift is how high the valve opens and duration is the period that the valve is open for. More lift/duration allows more air to enter the cylinder and more exhaust to leave the cylinder. Typically higher lift/longer duration cams are a little rougher, but depending on overlap that can be reduced.

I'm assuming you're talking about S3's. I'm running those currently and they are pretty aggressive, but don't idle much worse than S2's on my car. Although I've converted to speed density on stock ecu. You will sacrifice a little down low for big gains up top. Make sure to get upgraded valvesprings if you run these or the valves will float.
