In case you missed it and for those interested in performance and driving experience of both HO and SO engines there is a good driving and 0-60 test on YouTube. Can be found by searching for the Tungsten on Redline Reviews, 40:32 long, 2 weeks ago. Somehow I missed that one. The presenter is compelling in his delivery and might even sell you on the Tungsten. To bypass Tungsten review you can go to about minute :26 and see driving and acceleration tests of the HO and SO engines (Tungsten and Rebel). Even the SO is impressive.
