What is your goal? The turbo combo had already made the car a little more laggy. Adding big cams will make that worse, and to be clear 272 cams on a stock 2.6L is a big cam. Testing shows nothing beats the stock cams for response (248) but that you can gain a bit of midrange without sacrificing too much response with Tomei type R or type A (250 and 256). Duration is only a small part of it though, lift will help response and bigger lift needs valve springs. Ramp rate will also help it feel not as lazy, but aggressive ramp needs valve springs as well. I used Kelford 264 after reading lots of reviews about the Tomei having soft ramp rates. I've got strong torque from just under 4k rpm to redline, but my car has a few other mods to help and I run e85. I'd suggest you talk to Kelford Cams, Camtech or Clive Cams about your whole setup, current results and your desired goals.
