While diesels offer so many great statistics (fuel economy, etc) what they seem to lack is a positive tactile senation and a genral lack positive throttle response. I was just in italy driving a very current diesel specimen, and every time I stomped on the accelerator it just left me feeling flat and unsatisfied. Until this "vagueness" type quirk is ironed out of all diesels, I think to do this type of to conversion to a VX would be an agregious crime against the intent of vehicle's original design purpose. Remember, the JDM's were only 3.2's versus the U.S.'s 3.5 to help enhance the gas-type of throttle resonse magic I just mentioned.
