I am fairly certain it will not work on the 606 turbo without additional electronic modifications to fool the computer, and that's if it will physically work. From looking at the EPC, it's possible the 606 turbo could use two of the round discs to eliminate the exhaust feed pipe. You can't use the blockoff plate because the EGR valve is integrated into the mixer housing, unlike the 603, where the EGR valve and mixer housing are two separate parts.

The kit may work fine on the 606 non-turbo, used from 1995-1997. At least it seems that way from the EPC...
