What year is the car? Assuming a turbo was on the car, if the motor blew, they would most likely have replaced the whole engine. Do you know anything about he motor(what year it came from)? TD-84U shows as a GSR distributor...I don't see why a LS cap fits. If the car had no cel in the first place, that means the correct distributor is on the car but may have failed. If wrong distributor was on there it would have had a check engine light since day one.
