Well there are preliminary prices being discussed. The crank pulley kit at $399 looks a decent price if you want to keep the dampened OEM pulley. But considering that some have failed, I'd guess there are plenty of solid crank pulleys available for less. As I know the Vdamper alternative is a lot more, but its the only solution if you want a reliable oversize dampened crank pulley. However the "special" bit is the throttle body kit and the figure of $1599.99 is being suggested. However its not clear if this includes the APR ECU file or not. Lets see what UK prices will be. If the TB is £1600 then even I may pass at it, or at least I shall wait until there are some firm figures available demonstrating its value. BTW remember that this mod is such that upgraded charge cooling will be necessary.
