When I had my Z32TT it was upgraded by about 50HP (Sport 500 turbos and JWT ECU upgrade). Compared to my wife's E63S estate (0-60 in 3.4 seconds and 11.7 in the quarter mile) the Z felt slow. I still loved it! Enjoy your Z for what it is - one of the most beautiful cars in the past 50 years. Most classic cars are not acceleration competitive with today's higher performance cars but are loved for what they are!
