There was a garage that signed up on here on looking for info about the Z. This is the car they were working on, It was supposed to have a 1000hp target.
But you dont have to take out the rear bumper to replace the lights... Do you?

Mine was left all over winter with no coolant or radiator fitted & its fine now
