after swaping the engine the car is not going more than 200 Km. I guess the engine need somthing to open the rev limit.
So what I have to do ??
did you talk to the mechanic about swapping in the wiring harness and DME from a VANOS motor? Your problem is most likely that the VANOS unit is not being controlled, and so the intake cam is not being adjusted as it should. You HAVE to have this connected to take advantadge of the VANOS.
